PK-7M Low-Speed Freezing Centrifuge
Product Model:PK-7M
Maximum speed:7000r/min
Maximum centrifugal force:9100xg
Maximum capacity:6×1500ml
Product Introduction:
This model features mature technology and stable performance, primarily configured with 6×1000ml round cups or 6×1500ml square cups. It is widely used in production and research units such as blood stations, blood banks, pharmaceutical factories, blood products, and biochemical laboratories.
Technical performance and characteristics:
- High definition LCD screen display.
- Control system: ① Speed, centrifugal force (automatically calculated), temperature, time, rise and fall speed, rotor displays set parameters and real-time operating parameters on the same screen. ② The program storage capacity reaches 99 sets. ③ 16 speed up and down rate control to prevent secondary suspension. ④ It has multiple warning functions such as overcurrent, overvoltage, undervoltage, overspeed, overtemperature, and imbalance.
- Driven by a brushless AC variable frequency motor, it has no carbon powder pollution, long service life, three-level shock absorption, low noise, and minimal vibration.
- The PK-7M model uses imported well-known brand compressor units and environmentally friendly fluorine free R404a refrigerant. It has preheating and defrosting functions, as well as a unique heat dissipation system, which ensures good refrigeration performance of the instrument.
- The available rotors are made of high-strength and high-quality aviation alloys and biosafety covers to prevent aerosol contamination. The rotors can be sterilized at high temperatures and can be equipped with identification systems.
- All steel spray coated shell, stainless steel centrifugal chamber, rust proof, corrosion-resistant, electronic mechanical door lock, three-layer steel protective layer, ensuring environmental and personal safety.
