In nt tr ro od du uc ct ti io on n
Congratulations on your purchase of a Labconco CentriVap Mobile System.
Models are available for operation on 115V or 230V.
The Mobile System combines a concentrator and a cold trap in one cabinet. The
concentrator uses centrifugal force with heat and vacuum to rapidly evaporate and
condense solvents from biological and analytical samples. Centrifugation
eliminates bumping and foaming as vacuum is applied and also concentrates the
solute in the bottom of the vial. This allows recovery of solutes from sample
volumes as small as a few microliters. The concentrator is equipped with a 300
watt heater to speed evaporation by warming the chamber during processing. A
timed outlet for the vacuum pump connection delays the start of the pump until
the rotor reaches operating speed. A safety switch prevents the concentrator from
starting when the lid is in the open position and a latch prevents the lid from being
opened while the rotor is turning.
The microprocessor, which controls the operation of the heater and the motor,
provides excellent regulation and reproducibility of protocols. The end of the run
can be signaled by a manually preset timer. Nine different protocols can be stored
in memory so exact test parameters can be easily repeated.
As an integral part at the CentriVap Mobile System, the cold trap protects the
vacuum pump by trapping moisture, vapors and corrosive fumes as they evaporate
from the samples. The stainless steel trap is used for aqueous and organic
applications. For corrosive applications, the optional Glass Trap insert should be
used. The 230V models comply with CE regulations.

Before you install your CentriVap, you need to prepare your site for installation.
Carefully examine the location where you intend to install your CentriVap. You
must be certain that the area is level and of solid construction. In addition, an
exhaust means must be provided. An electrical source must be located near the
installation site.
Carefully read this chapter to learn:
The electrical supply requirements.
The exhaust requirements.
The vacuum pump requirements.
Refer to Appendix C: CentriVap Specifications for complete CentriVap electrical
and environmental conditions, specifications and requirements.
Electrical Requirements
The CentriVap Mobile System requires a dedicated grounded electrical outlet.
This outlet requires a 20 Amp circuit breaker or fuse for models rated at 115V
(60 Hz). A 10 Amp circuit breaker or fuse is required for models rated at 230V
(50/60 Hz). 115V models are equipped with a 20 Amp NEMA 5-20P plug. The
power cord on 230V models is equipped with a NEMA 6-15P plug. If this does
not match with the available receptacle, remove this plug and replace it with an
approved plug of the suitable style.
It is recommended that an emergency switch for disconnecting the mains in the
case of a malfunction be located remote from the CentriVap, preferably outside
the room in which the CentriVap is housed, or adjacent to the exit from that room.

Location and Exhaust Requirements
The CentriVap Concentrator should be located on a surface that is stable, flat and
level.
WARNING: If hazardous or flammable solvents are used, it is recommended
that a benchtop CentriVap Concentrator is used and that it is located inside
a fume hood. Heating of materials could lead to the liberation of hazardous
gases. In all cases, regardless of the solvent used, it is strongly recommended
that the vacuum pump is vented in a fume hood. An accessory secondary
trap is available to minimize the exhausting of solvents into the atmosphere.
This does not, however, negate the need to exhaust the vacuum pump into a
fume hood. Failure to properly vent the CentriVap will expose personnel to
potentially harmful chemicals.
The CentriVap has not been evaluated by an approval agency for the use of
biological, radio toxins or flammable liquids or materials.
Vacuum Pump Requirements
A vacuum pump must be provided by the user. A vacuum pump with a free air
flow rate of 90 liters per minute and 1.3 x 10-4 mbar blank off pressure is adequate
for aqueous samples. More volatile samples can be satisfactorily processed using
a diaphragm pump with a free airflow of 42 liters per minute and 200 mbar
vacuum. The inlet fitting on the vacuum pump must be suitable for 0.50 ID hose.
Vacuum pumps used with 115V models should be equipped with a 115V, 15 Amp
NEMA 5-15P plug. Vacuum pumps used with 230V models should be equipped
with a “reverse” IEC 320 plug. This will allow the vacuum pump to be plugged
into the receptacle on the back of the CentriVap.
IMPORTANT: To ensure that aggressive samples used in the CentriVap do
not damage the vacuum pump, it is recommended that all internal wetted
parts are PTFE or PTFE coated. When selecting the vacuum pump it is very
important to consider the flammability of the solvent that will be used. If the
solvents are flammable, an explosion proof vacuum pump or one suitable for
the solvents to be processed is recommended.

Vacuum Line Traps
When evaporating acids, it is advisable to include a soda lime acid secondary trap
in the vacuum line. This adds additional protection for the pump.
NOTE: Several components within the CentriVap are made from stainless
steel or aluminum and can be degraded if exposed to acids. Before
evaporating acids, be sure to contact Labconco.
A moisture trap, solvent trap and radioisotope trap are also available. Refer to
Appendix D: CentriVap Accessories for ordering information.
Space Requirements
Refer to Appendix C: CentriVap Specifications for dimensional drawings of the
CentriVap.
No person or any hazardous material should be within 12 inches of the CentriVap
Concentrator while it is operating.

Setting Up Your CentriVap
After you verify receipt of the proper components, move your CentriVap to the
level and sturdy location where you want to install it. There is no need to secure
the CentriVap to the work surface. Then, follow the steps listed below.
Emergency Access Into the Chamber
The CentriVap is designed to prevent access to the chamber in the event of a
power disruption. If it is necessary to open the lid when there is no electrical
power connected to the CentriVap, insert a small screwdriver or similar
instrument into the small round hole on the left side of the case near the top
behind the control panel. This will unlock the lid latch mechanism. While
holding the screwdriver in place, raise the lid with the other hand.
CAUTION: Never attempt to defeat the latch or open the lid while the
CentriVap is running. Personnel injury can result from moving parts and
chemicals.

Vacuum Pump Installation
The user-supplied vacuum pump can be installed inside the cabinet of the
CentriVap Mobile Console. To gain access to the pump area, grasp the front
lower panel near the top and pull it outward. The vacuum pump should be
positioned on the lower shelf of the cabinet. Attach the hose that is hanging from
the clear canister to the fitting of the vacuum pump. Clamp the hose securely with
the clamp supplied.

Chapter 3: Getting Started
Product Service 1-800-522-7658
10
Exhaust Port
Attach one end of a user-supplied hose to the exhaust port on the vacuum pump.
Clamp securely. Route the other end to a fume hood or other laboratory
ventilation device.
Installing a Secondary Chemical Trap Insert
A secondary chemical trap is included to minimize the exhausting of solvents into
the atmosphere. Unscrew the clear bowl of the canister housing from the head.
Remove both the upper and lower caps from the filter cartridge and insert the
small end of the cartridge into the hole in the center of the head. Reinstall the
clear bowl.
Be sure to use the proper cartridge for your application. A solvent cartridge is
included with the CentriVap Mobile Console. The moisture cartridge is used to
trap water vapor. The acid cartridge is used to trap acid vapors and the
radiochemical cartridge is used to trap radioactive waste.
When the media in the insert has changed color, discard the insert and replace it
with a new insert. For the radiochemical trap insert, no color indicator exists,
therefore it should be discarded after each use. Use a Geiger counter to monitor
the pump exhaust.
IMPORTANT: This radiochemical cartridge does not meet NRC filter
design recommendations.
After operating, properly dispose of all hazardous materials in compliance
with all applicable codes. Labconco is not responsible for improper disposal
of any materials.
Electrical Connection
Plug the power cord into the receptacle on the back of the CentriVap Concentrator
and plug the other end into a suitable power receptacle. Plug the power cord from
the vacuum pump into the receptacle on the back of the Concentrator. If the
vacuum pump has an off/on switch, turn the switch on. The concentrator will
control the vacuum pump.
Rotor Installation
Place the rotor onto the shaft of the Concentrator. Rotate the rotor slightly to
engage the drive pin in the shaft with the slots in the rotor hub. The top of the
shaft should be in line with the top of the rotor hub.
IMPORTANT: Do not use a rotor if it shows any signs of damage.

Ground Wire
CAUTION: When draining the CentriVap Cold Trap always attach the grounding
clip to the solvent catch pot to eliminate the risk of electrostatic spark ignition.
Chemical Resistance of CentriVap
Components
Your CentriVap Mobile System is designed to be chemical resistant to most
compounds that are commonly used in the concentration processes that are
performed in it. However, by necessity, the CentriVap is comprised of a number
of different materials, some of which may be attacked and degraded by certain
chemicals. The degree of degradation is obviously dependent on the concentration
and duration of exposure. Some major components of the CentriVap that are
susceptible to degradation are as follows:

If a rotary vane vacuum pump is used, most compounds used in the
CentriVap will degrade the oil if allowed to enter to pump. Frequent oil
changes are required.
Diaphragm vacuum pumps sold by Labconco have wetted parts either made
from PTFE or protected by PTFE coatings and are suitable for nearly all
procedures.
When using compounds in the CentriVap that are hostile to the materials of
construction, it is imperative that the equipment is appropriately maintained.
After each run, clean up all residues, spills and materials that might have
splashed in the chamber using agents suitable for the substance involved.

Drain the cold trap immediately after the collected ice is melted to prevent
corrosive liquids from residing in the trap. Flush out the trap with water after
draining.
DO NOT chip ice off the cold trap walls as damage may occur.
DO NOT start a rotary vane pump when the cold trap contains any liquid.
The liquid will be drawn into the pump and will contaminate the vacuum
pump oil.
If the compounds used attack acrylic, consider using the optional glass
chamber lid. Contact Labconco for ordering information.
If the stainless steel cold trap chamber is attacked by the compounds in use
consider using the optional Glass Trap insert. Contact Labconco for ordering
information.
When using a rotary vane vacuum pump the oil in the pump should be
checked often. It must be changed if it is cloudy, shows particles or is
discolored. The useful life of vacuum pump oil can be extended if the
vacuum pump is operated for an extended of time after the CentriVap run is
over. This allows contaminants to be purged from the hot oil. This must be
done with the inlet to the pump blocked off to prevent air from free flowing
through the pump. If the pump is operated at an elevated vacuum level, oil
will be expelled from the pump and damage will occur.
Monitor the secondary trap’s condition often and replace it when it is
saturated. A new acid trap is off-white and changes color to purple when
used up. A new moisture trap is blue and changes color to pink when it is
used up. The solvent trap molecular sieve does not change color when
saturated so extra care must be taken to determine when a replacement
cartridge should be installed.
Solvent Safety Precautions
CAUTION: The CentriVap is not classified as “explosion proof.” It has been
designed with safety as a primary consideration and should be used in a
prudent manner using “good laboratory practices.” It has been designed for
use with compounds as described in the United States National Electrical
Code Class I, Group D. The heater may be programmed to run as hot as
100°C, however, the heater element may normally run at 110°C. A thermal
fuse limits the heater to a maximum temperature of 141°C. It is important
that the solvents used are compatible with these temperatures. Do not
evaporate solvents that have an autoignition temperature below 180°C. Do
not evaporate solvents that are classified as Group A, B, or C by the National
Electrical Code. Evaporate only non-flammable or Group D solvents with
autoignition temperatures 180°C or above. Use of other compounds could
cause an explosion.

Chapter 3: Getting Started
Product Service 1-800-522-7658
14
CAUTION: Solvents used in the CentriVap may be flammable or hazardous.
Use extreme caution and keep sources of ignition away from the solvents.
When using flammable or hazardous solvents, both the CentriVap and the
vacuum pump should be operated inside a fume hood.
If a sample is spilled in the chamber it must immediately be cleaned up.
Hazardous materials such as strong acids or bases, radioactive substances
and volatile organics, must be handled carefully and promptly cleaned up if
spilled.
Do not store flammable or hazardous solvents within 12 inches (300 mm) of
the CentriVap.
IMPORTANT: Various Federal, State or local regulations may govern the
disposal of substances used in connection with this equipment. All users of
this equipment are urged to become familiar with any regulations that apply
in the user’s area concerning the dumping of waste materials in or upon
water, land or air and to comply with such regulations.

Chapter 4: Using Your CentriVap Mobile System
Product Service 1-800-522-7658

Planning
Thoroughly understand procedures and the equipment operation prior to
beginning work. The unique performance of the CentriVap is dependent upon the
proper balance of heat, vacuum and centrifugal force. If the proper balance is not
established, it is possible to damage or lose a portion of the sample. Therefore, if
you are unfamiliar with the CentriVap or are attempting a new protocol, it may be
helpful to make a trial run that is void of the sample you are attempting to
concentrate.
Glassware Selection
Normally, sample tubes should be filled no more than approximately half full.
Select the size of the sample tube so it is compatible with the rotor and the desired
sample size. Tubes should not be loose in the rotor. Rotors are available with
holes for various size tubes. Refer to Chapter 6: Accessories for your CentriVap
Mobile System for available rotor sizes.
Loading Glassware Into the CentriVap
Smooth operation of the CentriVap is dependent upon proper balance of the
machine. Therefore, if less than a full load of samples is run, it is important to
load samples into the CentriVap in a fairly symmetrical manner distributing the
weight of the samples evenly in the sample rotor.
Temperature Setting Guidelines
The evaporation rate achieved by the CentriVap is dependent upon a variety of
factors. These include the nature of the solvent, the temperature and the pressure
in the vacuum system.
As a general guideline, to speed the evaporation process, the CentriVap
temperature should be set as high as possible as long as the temperature will not
damage the sample or cause the sample to bump.
Time Setting Guidelines
The CentriVap Concentrator has two timers. The “RUN TIME” turns the entire
concentrator off after the user set period of time. This stops the rotation, turns off
the heater and vacuum pump and bleeds vacuum from the system. The heater
may be turned off prior to the concentrator turning off so heat-sensitive samples
may be protected from exposure to excessive heat after the solvent has
evaporated. To turn the heater off prior to stopping the entire system, enter a set
time into the memory at the “HEATER TIME.” When the programmed time
expires, the heater will turn off but the rotation and vacuum will continue until the
run time expires.
