Description
Thermo Fisher Scientific 1
1 Description RVT series Refrigerated Vapor Traps are reliable, easy-to-use, compact
benchtop traps for solvent vapor condensation and collection. Mechanically
refrigerated vapor traps replace dry ice/methanol traps, and are the easiest,
most practical, and safest way to protect high-vacuum, rotary vane oil
pumps in a vacuum system.
Solvents are removed from samples during vacuum evaporation with a
SpeedVac® Concentrator or during rotary evaporation and are collected in
the CFC-free Refrigerated Vapor Trap. Solvent vapors pass into a Glass
Condensation Flask and condense on its walls. This prevents the vapors
from reaching and potentially damaging the oil-sealed vacuum pump.
When used in conjunction with the ThermoSci VaporNet® controller,
RVT-series traps provide levels of solvent recovery equal to the most
elaborate liquid nitrogen traps.
Operating temperature is -105C.
The RVT5105 is controlled simply by an on/off (I/O) switch located on the
left side. An amber LED on the right front indicates that the unit is on. A
green LED indicates that the operating temperature has been reached and
the unit is ready to use.
The RVT5105 employs a cascade (dual compressor) refrigeration system to
achieve its low operating temperatures.
CAUTION! To assure safe operation and best results, read this
manual in its entirety before operating this instrument. Improper
operation can damage the trap or your vacuum pump.

Receiving and Inspection
Thermo Fisher Scientific 2
2 Receiving and
Inspection
2.1 Receiving Inspect the shipping carton upon receipt. If the carton is damaged in
anyway, call ThermoSci or your local distributor.
2.2 Unpacking Carefully remove the instrument from its shipping carton. Lift and carry
with two people, holding the unit securely underneath with both hands.
Compare the packing list to the box contents. If there is a discrepancy, call
your distributor.
2.3 Inspection. Inspect the unit for any damage that may have occurred during shipment.
Should there be damage, report it to the carrier and contact Thermo
immediately. Make sure the carrier inspects the damage and leaves an
inspection report. Register claims for shipping damage against the carrier or
his agent. Save the shipping carton in the event a return is necessary.
3 Installation
3.1 Site preparation The trap is typically placed on a bench top at least 26 inches (66 cm) deep
and located near a power outlet of the required voltage. The outlet must
have a rating of at least 13 A for 115V operation, or 7 A for 230 V
operation. The trap draws high current when first switched on; therefore,
other high-powered equipment, or equipment that will be affected by a
momentary drop in power, should not be placed on the same circuit as the
trap. The refrigerated trap and SpeedVac® may also be installed on a sturdy
mobile cart, such as Thermo Scientific’s Deluxe Convenience Cart,
(CC120/DX).
Provide adequate ventilation. Thermo refrigerated traps are air-cooled and
require at least 3 inches (7.62cm) of clearance for ambient air suction. The
RVT5105 draws air from the rear of the unit. Ambient temperature must
not exceed +90 °F (+32 °C) during operation.

Installation
Thermo Fisher Scientific 3
3.2 Other Components The following accessories are ordered separately:
Glass Condensation Flasks. GCF400 and GF4000
Order the wide-mouth GCF400 flask (4-liter Glass Condensation
Flask) for all standalone concentrators except for the SC250EXP.
Order the GF4000 for use only with the SC250EXP.
The glass flasks are quickly exchanged between runs and are easy to clean.
Having several available permits uninterrupted refrigerated trap operation
while the used vessel is being defrosted, cleaned and dried for next time.
CryoCool®Heat Transfer Fluid. A permanent, safe, efficient, and
economical alternative to methanol or ethanol. CryoCool does not
evaporate, has very low water absorption, is odorless, and non-toxic. Order
SCC1 for a 1-liter bottle; order SCC5 for a 5-liter bottle.
In addition, Thermo Scientific offers a complete line of other
components required for drying, including vacuum tubing kits,
SCT120 Chem traps and replacement Flask Covers for the GCF400.
3.3 Preparing for
Operation
Switch the trap OFF. Connect the power cord to the receptacle on the right
side of the instrument. Plug the trap into an appropriate wall outlet.
CAUTION! Before connecting the Refrigerated Vapor Trap to an
outlet, check voltage, frequency, and amperage to be sure they match
the power requirements indicated on the rear of each instrument. (115
VAC/60 Hz, 13 A, 230 VAC/50 Hz, 7 A.) If there are any questions,
please consult an electrician.
As a safety feature, units are equipped with a three-prong grounded plug
that fits a grounding-type power outlet. Consult an electrician to replace
outlet if necessary. Do not defeat this safety feature by modifying the plug.
These units are “FOR INDOOR USE ONLY”. Avoid operating in areas of
excessive humidity or extremes of temperature.
Pour CryoCool Heat Transfer Fluid (500 ml) into the stainless steel trap
chamber. Before each use, be sure the chamber is filled to the correct level. If
necessary. add more CryoCool.
Cryocool can now be drained from the RVT5105 system to remove
unwanted ice or other contaminates after the system has been fully
defrosted. Refer to Section 5 on page 10 for troubleshooting and
maintenance details.

Glass Condensation Flasks Glass condensation flasks are ordered separately. They come in two types:
the GCF400 and the GF4000.
3.4 GCF400 The GCF400 is an open-mouth flask used with 4-liter traps. The wide
mouth facilitates cleaning and removal. A rubber Flask Cover (FC400) fits
over the top, and tubing attaches to this by means of fittings pushed into
molded ports on the rubber cover. This forms the vacuum connection. An
insulating cover fits over the flask to seal in the cold and seal out
atmospheric condensation from the refrigerated chamber.
The figure below shows the GCF400 installation in the RVT5105 chamber.
To the left is an insulation “lift and turn”retaining clip.
Figure 1. GCF400 in RVT5105 chamber
Installation Place a clean, dry Glass Condensation Flask into the stainless steel chamber.
Fit the black insulating cover over the flask. Seal flask mouth with the black
rubber Flask Cover (FC400). Press down flask and black insulating cover so
that the level of CryoCool rises around the flask, and so that the flask, its
cover, and insulation are seated to operating position. Lift and rotate the two
black retaining clips to hold down both the insulation ring and the Glass
Flask.

Installation
Thermo Fisher Scientific 5
The figure below shows the GCF400 with the black insulation ring, locked
down in the chamber by means of the retaining clips.
Figure 2. GCF400 locked down in chamber
This will fully seal the chamber. Withdraw the flask again and verify
that the level of CryoCool came to within about a half-inch (12–15
mm) from the top (shoulder) of the flask. If the level is low,
carefully pour more CryoCool into the chamber while holding
down the flask. Immediately wipe clean any CryoCool that spills onto
the rubber chamber seal or Flask Cover.
3.5 GF4000 (use with
SC250EXP only)
The GF4000 is a wide-mouth threaded flask used exclusively with the
SC250EXP SpeedVac system. The wide mouth facilitates easier cleaning
and removal of solvents.
A black insulating cover fits over the flask to seal in the cold and seal out
atmospheric condensation from the refrigerated chamber. A large
polypropylene vacuum connection fits over the top and is secured by means
of a threaded poly nut, and tubing attaches to this by means of stainless steel
fittings. This forms the vacuum connection.

Figure 5. GF4000 with SC250 vacuum cap installed

Installation
Thermo Fisher Scientific 7
To install the GF4000, place a clean, dry Glass Condensation Flask into the
stainless steel chamber. Fit the black insulating cover over the flask. Lift and
rotate the two black retaining clips to hold down both the insulation ring
and the glass flask.
NOTE: After the large Polypropylene cap has been installed, follow
directions for installation of vacuum lines included with the SC250EXP
system.
3.6 Tubing Connections A 1/2-inch O.D. fitting is required to connect tubing to the rubber flask
cover. If tubing from the SpeedVac concentrator (or other drying apparatus)
is wider (for example, SC250DDA or SPD131DDA), a reducer fitting
(such as the 3/4 –1/2 inch M60-0044-24 included with these units) is
needed. Fit the fitting to the tubing, and press the fitting into the molded
port on the rubber cover. Fit the suction line from the pump end of the
system in a similar manner.
For tubing instructions, refer to the installation instructions with tubing kits
(UTP-TYG) or with the SpeedVac concentrators. It does not matter which
molded port is used for the SpeedVac and which is used for the pump. The
best setup will have the shortest, straightest line of tubing with the fewest
amount of bends. It should achieve a convenient and comfortable lay of
tubing, with little stress on the fittings. The rubber cover and flask should be
easy to remove for system maintenance.
NOTE: Previous SpeedVac users may note that the GCF400 does not have
an internal funnel like the older GIT-type trap. In many cases, this is not
needed to assist in vapor collection. However, if desired, an extender fitting
(such as the M60-0044-14 straight fitting included in the UTP-TYG kit)
can be inserted under the rubber cap, so that vapors from the concentrator
enter toward the center of the flask.

Operation
Thermo Fisher Scientific 8
4 Operation
4.1 Sequence of
Operation
After preparing the unit as described in Section 3 on page 2, switch it ON.
The power switch is located on the left side of the RVT5105. An amber
LED on the front illuminates when power is on.
It may take up to 90 minutes for the trap fluid to reach its operating
temperature. When this occurs, you may begin drying operations as
outlined in the instruction manual of your drying apparatus.
The RVT5105 Refrigerated Vapor Traps are designed to operate
continuously and may be left on for extended periods. Be sure to regularly
check the glass trap or flask and empty it as required. For maximum
efficiency, replace with clean vessel when not more than half full (see Section
3.1).
The RVT5105 operates in the following sequence. When you switch the
RVT5105 ON, an amber LED located on the front panel will illuminate.
The unit starts up and both the fan and compressors can be heard. When
the trap temperature reaches -75°C (approximately 60mins), a green LED
also located on front panel illuminates to indicate that trap is ready to be
used. Ultimate trap temperature, -105°C, typically will be reached in
approximately 90 minutes. During operation, the trap temperature may rise
because condensing and freezing solvent vapors cause transfer of heat into
the trap.
4.2 Emptying the Glass
Vessel
Vessels are available separately and are described in Sections 3.4 and 3.5.
During system operation, solvent vapors from the SpeedVac will collect in
the glass vessel. The vessel must be regularly emptied to keep the entire
system operating at peak efficiency. If the vessel is not maintained, it may
become so full that sample drying rate is adversely affected. Another
consequence of a full vessel is that solvent vapors are more likely to
contaminate and possibly damage an oil-sealed vacuum pump that may be
used with the SpeedVac system.
Empty the glass vessel before it is half full. Often it is convenient and good
practice to change the vessel at the end of the workday or workweek, no
matter the depth of fill. For aggressive solvents, you may wish to remove the
vessel at the end of each run for maximum protection of the system
components.
CAUTION! Refrigerated vapor traps reach low operating
temperatures that can cause severe damage to unprotected skin.
Wear protective gloves and clothing when removing glass vessels.

Operation
Thermo Fisher Scientific 9
To remove the GCF400 or GC4000 for cleaning:
1. Bleed the system back to atmospheric pressure.
2. Remove the rubber flask cover from the flask on the GCF400 or by
unscrewing the poly nut on the vacuum connector used on the
GC4000, leaving tubing attached to cover.
3. Withdraw the flask partially from the chamber and allow CryoCool to
drain briefly.
4. Fully remove the flask and insulating black foam ring.
5. Avoid thermal shock by placing the flask on several thicknesses of
absorbent paper toweling and allow to come to room temperature.
6. Insert a spare GCF400 or GF4000, clean and dry, into the chamber.
Cover with insulating Black foam ring, and seal with either FC400 Flask
Cover (for GCF400) or large Polypropylene cap (used with GF4000
only).
7. Make sure FC400 rubber cover is seated firmly for a good vacuum seal
or that the Polypropylene cap is screwed down firmly.
This easy system maintenance can be done in a matter of minutes; the
Refrigerated Vapor Trap need not be shut off during this process. When the
used flask has defrosted, dispose of contents in an environmentally
responsible manner. Clean and dry all flasks for next use.
NOTE: If the Refrigerated Vapor Trap is not needed for several weeks, you
may wish to shut it off between uses. Before switching on again, always
remove the used glass vessel and replace with a clean, dry trap. Check the
condition of the CryoCool; if a layer of water is visible under the CryoCool,
remove by opening the drain on the right side of the instrument (refer to
Section 5).
Failure to follow these precautions may cause the glass vessel to break when
the trap returns to operating temperature.

Maintenance and Troubleshooting
Thermo Fisher Scientific 10
5 Maintenance and
Troubleshooting
5.1 Replenishing
CryoCool
When cold, CryoCool condenses water vapor from the air and develops a
build-up of ice. This process is accelerated in humid environments. Loose
crystals may be removed with a strainer. Periodically, the CryoCool must be
refreshed if:
You see an ice build-up on the stainless steel chamber walls; the glass vessel
rises above its usual position, indicating an ice build-up beneath; or the
refrigerated trap seems to be losing efficiency.
The RVT5105 has a drain valve that allows you to removed the defrosted
Cryocool and water contaminates directly from the condenser. To operate
the valve:
Turn the unit off and allow it to defrost (this could take several hours); or
you could pour hot water to melt the ice.
The drain valve may be hooked up to a hose with 3/8 in. barbed fitting to
drain directly into a waste can.
The following pictures show the drain valve open and closed:
Figure 6. Drain valve open

Maintenance and Troubleshooting
Thermo Fisher Scientific 11
Figure 7. Drain valve closed
To reuse CryoCool that has a layer of water, transfer it to a container and
allow to settle again into a bilayer. Place in a freezer until the water layer
freezes. The liquid fraction is CryoCool, which can be reused. Decant off
the CryoCool and dispose of the ice.
CAUTION! Refrigerated Vapor Traps reach low operating
temperatures that can cause severe damage to unprotected skin.
Wear protective gloves and clothing when removing CryoCool, ice,
and glass vessels from the trap.
5.2 Vibration If the vapor trap vibrates excessively, have the line voltage checked with a
voltmeter. The voltage must be above 108V for 120V units and above 209V
for 240V units.
CAUTION! Low line voltage may cause thermal overload of the unit.
5.3 Cleaning the
Condenser
Vapor traps require proper air flow for ventilation. At least every three
months, clean the condenser grill. Dust and dirt on the grill can block air
flow. Be sure to turn the trap off before cleaning so that dust and dirt are
not drawn into the trap. Use a vacuum cleaner with a brush attachment, or
purge the condenser with compressed air.
The refrigeration system in the trap is hermetically sealed and does not
require maintenance.
