Ø The 3-18 series are widely used in molecular biology, molecular chemistry and PCR laboratories. Can be equipped with a variety of rotor capacity, cost-effective.
Ø Unique patent technology, new composite rotor, super light, high strength, slow heat conduction, strong corrosion resistance, fast speed up and down. Patent No.: ZL 2015 20661675.0
Ø The surface of the machine adopts fine sand grain plastic spraying process, and the executive standard is ISO9001 class I standard.
Powerful functions:
1. A wide selection of rotors and adapters are available for all centrifuge tubes from 0.2ml to 100ml.
2.The maximum centrifugal force is 25250 × g.
With 1 × G (speed up to 18500rpm, increasing by 1 RPM).
3. It has the function of differential time centrifugation: the specific time of speed up and down can be set freely, and the time of speed up and down can be set arbitrarily between 5S and 30min.
4. It has the function of gradient centrifugation: it can freely set the speed and centrifugation time of 1 to 10 gradients.
5. It has the function of inching centrifugation: it can carry out instantaneous centrifugation after setting the speed.
6. It has the function of timing centrifugation: the opening time of the centrifuge can be set freely, and the centrifuge can also run automatically after the laboratory is unmanned.
Maximum security
1. It can be equipped with biosafety centrifuge, biosafety air tight rotor and biosafety air tight adapter to prevent biological pollution. It is suitable for centrifugation of dangerous samples, such as infectious virus, infectious bacteria and radioactive samples.
2. The door cover is fixed by equilateral triangle, the force is uniform, and the centrifuge is safer during operation.
3. Electronic door lock, all steel inner cavity protective sleeve, T45 cold rolled steel body and 304 stainless steel centrifugal cavity are adopted; (4) heavy metal safety protection and primary buffer material to protect personal safety;
4. The emergency cover opening is equipped with a protective head on the side of the instrument, and there is no pull switch, which is convenient to open the cover in case of emergency and eliminates the potential safety hazard caused by misoperation.
5. The centrifugal chamber is treated by sand blasting, which has strong corrosion resistance and no light pollution.
6. The stainless steel centrifugal cavity has high strength and small wind resistance. There is no crack prone welding line under impact.
7. The noise of the whole machine is 60 dB, and the operation is quiet. Prevent hearing loss.
8. Environmental refrigerant R404 is used to prevent air pollution.
9. It is equipped with over speed, over temperature, imbalance and door cover protection, 3-level rubber shock absorption, good automatic balance function and imbalance automatic stop function to protect personal and machine safety.
The control of keeping improving
1. AC frequency conversion motor is driven, and it is stable and quiet without maintenance
2. It has the function of shortening the start-up and braking time. The braking time is controlled by acceleration and deceleration of gear 15 respectively
3. Large screen color display, beautiful appearance; Touch panel operation, simple and convenient. The setting of centrifugal force parameters can be accurate to 1 × g. The speed can be accurate to 1 rpm and the time can be accurate to 1 s. The large screen displays the parameters such as speed, centrifugal force, time, temperature, acceleration and deceleration. The parameters can be changed during operation without shutdown;
4. When the countdown time is less than one minute, it is displayed in seconds.
5. adopt imported high efficiency refrigeration unit and imported solenoid valve, with high temperature control accuracy.
6. Refrigeration function: the rotor temperature can still be kept at 4 ℃ at the highest speed; It has the function of prefabrication and cooling; Quick cooling function, reduced from room temperature to 4°C in 15 minutes.
7. The height of the whole machine is small, and the angle of automatic cover opening is small. Easy to operate.
