Prism R Refrigerated Microcentrifuge 1
1. Safety Precautions
Before using the Prism R refrigerated microcentrifuge for the first
time, please read this entire operating manual carefully. To guarantee
problem free, safe operation, it is essential to observe the following
points:
1.1. Operation Safety Precautions
1. When using infectious, radioactive, toxic and other solutions
which may pose health risks, please observe the appropriate
safety precautions.
2. Do not use this machine in a potentially explosive environment
or with potentially explosive chemicals.
3. Install the machine in location free of excessive dust.
4. Avoid placing the machine in direct sunlight.
5. Choose a flat, stable surface capable of withstanding the
weight of the machine.
6. Install the machine in the room temperature 15~30°C, relative
humidity 20~80%.
7. Don’t block the air vents.
8. Make sure the power source conforms to the required
power supply specifications.
9. To avoid electric shock, make sure the machine is plugged
into a grounded electric outlet.
10. Do not allow water or any foreign objects to enter the various
openings of the machine.
11. Switch off the power switch before cleaning or performing any
service on the machine, such as replacing the fuses.
12. The rotor and the rotor lid must always be installed
securely on the motor shaft.
13. Always load the rotor symmetrically. Each tube should be
counterbalanced by another tube of the same type and
weight.

2
14. To guarantee sufficient ventilation, ensure that the
centrifuge has at least 30 cm of free space on all sides,
including the rear.
15. Repair should be carried out by Labnet International'
authorized service personnel only.
16. Use original spare parts and accessories only.
Warning Label: Please be aware of the danger of electric shock
or other dangers.

Prism R™ Refrigerated Microcentrifuge 3
2. General Description
The Prism R refrigerated microcentrifuges is a compact, bench-top
centrifuge which is suitable for both research and clinical laboratories.
The motor is brushless and requires no routine maintenance. It is
supplied with a 24 x 1.5/2.0 ml rotor for micro samples. The maximum
speed of Prism R is 13,500 rpm (17,135 rcf). The temperature range
is from –10°C to 40°C.
2.1. Features

Powerful refrigeration system, maintain 4°C at max. speed
Includes unique easy access rotor (24 x 1.5ml)
Exceptionally quiet and compact
Optional StripSpin adapter available for 0.2ml tubes and strips
Compact, ergonomic design
User-friendly operation interface.
Quick button for instant run without setting
Low noise level
Complies with CE, RoHS
3. Getting Started
3.1. Unpacking
The centrifuge is delivered in an external carton and an internal
carton with protective PE foam cushions. Remove the centrifuge from
each carton. All packaging should be retained until it has been
established that the centrifuge is working properly.

4
Open the Prism R refrigerated microcentrifuge package and confirm
that all items are included:
Prism R unit with a 24 x 1.5/
2ml
rotor and a rotor lid
Operation manual
Electric fuses (7A &3.15A) Warranty card
Rotor wrench Power cord
If there are any items missing, damaged, or not according to your
order, please contact your distributor or sales representative
immediately.
Note: Please use 7A fuse in power source 100~120/50~60Hz
countries, while 3.15A fuse is for power source 200~230V/50~60Hz
countries.
3.2. Initial Operation
Place the machine on a stable, flat table. Please keep the machine at
least 30 cm from the surrounding area or objects.
Mains power and frequency “MUST”be compatible with the
information given on the product label on the rear of the centrifuge.
Connect the power cord to the power socket of the centrifuge, then to
the power source. Switch the Power On/Off switch to turn on the
centrifuge. After the LCD display is on and the buzzer beeps twice,
the centrifuge is ready to operate.

3.3. Opening and Closing the Lid
The lid can be opened only when the centrifuge is powered on. Press
button to open the lid.
The lid will be locked automatically when the user presses down the
front edge of the lid.
Note: Do not slam the lid!
3.4. Loading the Rotor
For safety reasons, the rotor must be loaded with centrifuge tubes
symmetrically. The difference in the weight between the tubes should
not exceed 0.1 gram.
The centrifuge tubes should be loaded in pairs opposite each other
and each should contain roughly the equal weight of sample. One or
two additional loaded tubes may need to be added to achieve this.
Please refer Figure 1 to see an example of a properly loaded rotor.
Attention: To reduce air friction and noise, the rotor lid should
be attached to the rotor during centrifugation. Make sure that the
rotor lid snaps securely into place, by pressing down on center
catch.

3.5. Starting and Stopping a Run
Please refer Chapter 5 Operation to set up your preferred settings of
time, speed and temperature.
To start a run, press down the (START/STOP) knob.
When the pre-set time expires, the centrifuge will stop automatically.
To stop the centrifuge prior to the expiration of set time, press the
(START/STOP) knob again.
When the time is set as “continuous”( - - ), the centrifuge will run
continuously. To stop the continuous run, press the
(START/STOP) knob.
By pressing and holding the button, the centrifuge will continue a

short-run of set speed. The short-run will stop if the button is
released.
Note:
1. For safety reasons, the (START/STOP) knob will be
inactivated when the lid is open. A symbol “ ” will be
flashing until the lid is closed.
3.6. Emergency Lid Release
When the lid can’t be opened by pressing the button, users can
open the lid manually. First, turn off the power of the centrifuge.
Second, use a flat-head screw driver or other tool to remove the
Emergency Lid Release Plug ( Please refer Figure 2 ) on the
right-hand side of the machine. Third, pull the wire (attached to the
plug) while gently pushing downward on the lid. The lid willnow
release.
