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.

Ⅴ、PRECAUTION

1. In order to safety working and correct centrifuging, please take the machine in a solid,

shockproof and horizontal table, please ensure the four feet equal force.

2. Before using, please move out the foreign body; check the rotor is correctly installed in the

rotor seat, please ensure the ro

3. tor and motor shaft with very good connection.

4. Set the speed strictly under the speed range allows, It is strictly prohibit to work

over-speed.

5. No unbalance working, centrifuge tube must be placed symmetrically, no single tube

working, the tube solution must be uniform to ensure balanced operation.

6. No high-speed working without rotor.

7. Remove the rotor must use the special handle which together with the machine or use

non-metallic tools gently tap the rotor first, repeated until the shock between the rotor and the

motor shaft connection. It is strictly prohibited to release the screw directly after the hard pull

up, so as not to damage the motor's flexible support.

8. Before using the rotor and centrifuge tube to check whether there are cracks, corrosion

traces and aging phenomena, if necessary to immediately replace, it is strictly prohibited to

use the rotor with crack or corrosion.

9. Check whether the external power supply meets the requirements, the instrument is

reliable grounding.

10. No moving and No lid-open during the centrifuge running, Do not open the lid when the

motor and rotor are not completely stopped.

11. The instrument or rotor disabled for three month, please running at low speed 10min, then

allow to work on high speed.

12. To prevent damage to the instrument and personal safety, No mixed using other company

Rotors.

13. To prevent the machine and spare parts corrode, Do Not place a container with liquid on

the instrument.

14. Please clean the machine and close the power switch and power plug after using.

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）Acc/Dec Set：press“Set” to move the cursor to“Acc” or “Dec”, when flashing，Press "+"

or "-" to acc/Dec set，then press“Enter”to confirm.

The system supports 0- 9 a total of 10 files, 0 is the fastest, 9 is the slowest, when the

use of larger volume of the angle rotor or swing-out rotor, you can choose a little bit of the

slows, the other can choose a little faster file Bit. Generally recommended to use 5 files;

Finally press "Enter" to confirm.

7) When the "Short" button is pressed, the machine centrifuges, and when the mobile phone

is loosened, centrifugation stops.

Remind: each step is completed, should immediately press the "Enter" to be confirmed.

8) Finally, check the parameters on the screen confirm correct, press the "Start" " to run.

9) The running time countdown to "0", the centrifuge will automatically stop, the buzzer

ring, when the speed is 0, press the "Stop / Open" button, you can open the lid. During the

event of an emergency, press the "Stop / Open" button, the buzzer does not ring when the

centrifuge stops running.

Note: Do not open frequently, the proposed interval of 10 seconds to avoid

damage to components

10) Open, take out the tube carefully, complete the separation process.
