4-21R Floor High Speed Refrigerated Centrifuge
Scope of application:
The 4-21R machine is widely used in clinical medicine, biochemistry, genetic engineering, immunology and other fields. It is a necessary instrument for centrifugation in hospitals, research institutes and universities at all levels.
The 4-21R series centrifuges not only have the basic characteristics of high speed and large capacity, but also have ergonomic operation, excellent temperature control performance and excellent product quality.
Refrigeration centrifuge has many characteristics, such as compressor control technology to provide automatic refrigeration standby function, optimize refrigeration performance, reduce energy consumption.

Product characteristics:
- Double lock button electronic door lock, full steel door cover protection, superior to industrial standards.
- External heat dissipation design, efficient heat dissipation of the internal circuit of the main engine, the temperature rise in the cavity is better than the industry standard, to ensure the safety of the sample.
- High quality hydraulic rod, imported damper seal, hydraulic damper does not decay for ten years.
- Food-grade integrated silica gel sealing ring, life-long service, more sealable.
- The automatic identification system of magnetic rotor automatically matches the corresponding rotor program, prevents the rotor from overspeeding and ensures centrifugal safety.
- Humanized design is easy to operate, parameter setting is directly digital input, accurate to individual intelligent status prompt.
- It has many protective functions, such as door cover, overspeed, over-temperature, over-current, over-pressure, over-heat, etc. The solution is more stable with simultaneous voice and text display.
- Unique noise reduction system, running more quiet.
- Self-diagnostic function voice text prompts and displays solutions, more stable and reliable with electronic instructions, never lost, easy to use.
4-21R Display Screen (7inches)
Design of Chinese knot heat sink
7inch 3D HD LCD full touch screen, 3D interface is simple and clear, all parameters are clear at a glance.
Multi-function knob Home key, can be set to modi fy parameters independently.
- In the stop state, press the machine for more than 3 seconds to start running.
- When running, the machine starts to shut down after more than 3 seconds.
- Counterclockwise rotation reduces the value, clockwise rotation increases the value, and flexibly adjusts the required value.
Self-developed HMC system
>Long press the startup key 3S to open the startup mode.
>Humanized design is easy to operate, parameter setting is directly digital input, accurate to individual intelligent status prompt.
>The rotational speed, centrifugal force and temperature curves are displayed on the same screen to meet various centrifugal requirements, and the change relationship is clear and visible.
>Super large storage space, can store up to 99 program groups, 99 usage records and fault records can be traced.
Fifteen speed-up and speed-down curves can be selected and free parking time can be set.
>Two timing modes are optional, start timing and arrival speed timing.
>Password lock function, users can set password to lock the host or parameters to prevent misoperation.
>There are many languages in the startup interface, which can be switched between Chinese and English.
4-21Rcentrifuge can be adapted to a series of high-quality aluminium and patentable new material rotors. In addition to conventional rotors, 4-21R centrifuge al so adds several specially designed rotors to meet specific application requirements. (For customized rotor, please contact manufacturer)
