PK-4F Low Speed Desktop Centrifuge- Vacuum Blood Collection Tube Automatic Cap Removal Centrifuge (Cap Removal)
Product Model:PK-4F
Maximum speed:6000r/min
Maximum centrifugal force:6450xg
Maximum capacity:48 vacuum blood collection tubes
Product Introduction:
This series of instruments includes specifications such as 48, 80, 100, 120/128, and 240 units, as well as two types of models for room temperature freezing. Mainly used for collecting blood samples in departments and hospitals using vacuum blood collection tubes, there is no need to manually remove the cap (cover). Through the principle of instrument rotation centrifugation, the centrifuge tube and cap (cover) are automatically detached to continue centrifugation. Thus, it completely solves the problems and challenges of blood resuspension, bacterial infection risk, and low work efficiency caused by the vibration generated during the manual de capping process of using separation vacuum to collect blood vessels.
Technical performance and characteristics:
- 4-inch high-definition, high brightness true color LCD display screen, displaying speed, centrifugal force (automatically calculated), time setting parameters, and real-time operating parameters on the same screen, simple and intuitive, and modifying parameters without stopping the machine.
- Running in 16 speed up and down curves to improve centrifugal effect and prevent secondary suspension.
- Equipped with overspeed, door cover self-locking, safety protection layer, and fault diagnosis and handling system to ensure personal and instrument safety.
- The brushless motor is directly driven, with a large starting torque and fast acceleration.
- Using customized high-quality NR rubber, three-level resistance vibration reduction, and good centrifugal effect.
- Unique airflow guidance or powerful refrigeration system ensures the activity of the sample.
- Programmable operation, with over 99 sets of storage.
- The centrifugal chamber is made of high-quality 316 stainless steel material, which is rust proof, corrosion-resistant, and durable.
- Reaching speed timing and starting timing, jog mode, countdown less than one minute displayed in seconds, supporting programmable loading to meet the precise separation needs of different industries.
- Electronic door lock, just press lightly to close the door, easy and safe.
- Suitable for vacuum blood collection tubes with two lengths of Ø 13 75mm/100mm, with a success rate of over 97% for removing the cap.
