一、Features and Uses
CENVCC-3 is a microcomputer-controlled desktop vacuum concentrator. made by full steel body. the
surface is spray-coated, with good rigidity and high strength. It has novel shape, beautiful appearance, low
noise, rising temperature slowly, safety and reliability etc
This machine use frequency conversion motor. stable speed and maintenance free.Adpot high-quality
solenoid valve and fully closed microporous filter ensure smooth and safe return air. LCD display
temperature, PID algorithm temperature control, highly temperature accuracy. adopts 304 stainless steel
inner cavity, transparent high-strength lid and aluminum rotor. with strong corrosion resistance, not easy to
scratch,has a long service life
Ⅱ、Working principle
The vacuum concentrator is a method in which the sample is continuously pumped by a
vacuum pump while being centrifuged, or even close to vacuum, so that the solvent in the
sample is quickly evaporated, the sample system is rapidly concentrated or dried, and the cold
trap and the filtration method can be effectively used,which collected evaporated solvent. This
model is suitable for RNA/DNA in the fields of molecular biology, biochemistry, genetics,
analytical chemistry, quality control, etc., as well as protein concentration or drying. The
sample after centrifugation and concentration can be conveniently used for various qualitative
and analysis of chemistry, biochemistry, bioanalysis, immunoscreening and instrumental
analysis.

Ⅶ、Working procedure
1) the centrifuge placed on the platform, visual to balance, shake and check whether the
centrifuge placed smoothly.
2) confirm the placement is stable, turn on the power, press the power switch, press the "stop
/ open" button, the lid can be opened.
3) Open the lid, the selected rotor gently placed on the motor shaft, screw on the screw so
that the rotor and the motor shaft tightly connected together (Note: it should be careful
and gentle, to avoid shaking and pull up and down, so as not to Damage the motor
support), and then put the tube set or adapter on the rotor, complete gently turn the rotor,
the rotor should be flexible rotation, Tube set (adapter) on the rotor should be tilted freely,
no block and rub Touch the phenomenon.
4) Put the tube filled with the same amount of test solution symmetrical into the tube set to
ensure that the rotor balance operation.
5) close the lid and check whether it has been locked (closed gently lift the lid, the lid is not
open. If the lid is not closed, press the "Start", the "time display" window will display "
E3 ").
6) set the rotor number, speed, time and other operating parameters.
(1)Set the speed: press the "Set" key, move the cursor to the "speed setting" position,
when the speed digital flicker, that is, enter the speed setting, then press the "increase
key" or "reduce key" to set the speed of this operation, after setting, press the
confirmation key to confirm the parameters.
Special reminder: The horizontal rotors and different adapters of this machine have their
own rotor numbers and maximum speed limits. Users must strictly observe the speed
limits of the rotor parameters when setting the speed parameters. Overspeed operation is
strictly prohibited to ensure safe operation.
(2)RCF set：Press“Set”to move the cusrsor to“Speed indicator”, when flashing，it is speed &
RCF switching state，Press“+”or“-” Switch the speed to RCF, “RCF”indicator，Press“Set”
move to，“Speed/RCF set”，when flashing，Press“+”or“-” to set and press “Enter” confirm
(3)Time：press“Set” to move the cursor to“Time Set”, when flashing，Press "+" or "-" to time
set，then press“Enter” confirm.

4. Compressor start / stop button
3、The operating procedures of the instrument are as follows:
1. Place the cold trap on the table stably, and the table shall be flat without strong vibration
and strong heat source.
2. After confirming that it is placed stably, connect the air inlet with the pipe for
concentration instrument, and the air outlet with the pipe for vacuum pump, and lock it
with clamps.
3. Plug the power cord into the power socket.
4. Turn on the power switch.
5. Press the start button of the compressor to cool the compressor. At this time, the
operation indicator lights up. If you need to stop cooling, press the stop button directly (the
compressor will also stop when the temperature reaches the set temperature).
The temperature control settings are as follows：

display is P0. Press the setting key again to set the required starting temperature through
the up and down keys;
P1 set stop temperature: press the set key to enter the internal menu, the digital display is
P0, switch to P1 through the up and down keys, and then press the set key to set the
required stop temperature through the up and down keys;
6. Defrosting: the cold trap is equipped with a one button defrosting button. When the
frost in the freezing chamber is serious after shutdown, press the defrosting button to
defrost (at this time, ensure that the compressor is in the stopped refrigeration state). When
defrosting is completed, press the defrosting button again to reset the button. If there is a
large amount of effusion in the freezing cavity, use a tool to unscrew the water drain valve
on the left side of the instrument to discharge the effusion (confirm that the seal is
complete when tightening).
7. Please turn off the power after use.
8. The cold trap host provides one year warranty. In case of non-human damage to the
product, the company will provide free maintenance service within 1 year from the date of
purchase. In case of human damage within 1 year or failure beyond the 1 year warranty
period, the company will charge a certain cost for maintenance. Repair by unauthorized
professionals. Unauthorized professionals shall not open the machine without the
permission of the company; All repairs and adjustments must be carried out by
professionals in accordance with the maintenance manual. The company will not be
responsible for the maintenance and adjustment of unauthorized personnel!
