The company mainly produces various kinds of laboratory
centrifuge/moisture rapid tester and vacuum centrifugal
concentrator and has passed iso9001:2015 quality management system
certification, ISO13485:2016 medical device quality management
system certification and CE certification. Led the preparation of
ASTM international standard for total solid content of natural
rubber.
The speed of high-speed refrigerated centrifuge can reach more than
10000rpm, with the performance and structure of refrigerated
centrifuge, high-speed refrigerated centrifuge Angle head is made
of titanium alloy or aluminum alloy. The centrifugal tube is made
of polyethylene hard plastic with cover. These centrifuges are
mainly used to collect microorganisms, cell fragments, cells, large
organelles, sulphuric acid precipitates and immune precipitates.
Characteristic:
1. Adopt Mitsubishi PLC (in accordance with EU Electromagnetic
Compatibility Directive 2014/30/EU and IEC_61131-2-2007) and Weilun
touch screen (in accordance with NEMA4 protection regulations and
EU CE electrical certification standards), with independent
research and development control panels and high torque AC
frequency conversion The motor is stable and quiet, providing a
comfortable laboratory environment.
2. Fluorine-free refrigeration compressor unit and environmentally
friendly refrigerant R404a, with a wide temperature control range:
-20 °C - +40 °C, and can be set during the operation of the
centrifuge; with pre-cooling function, can quickly cool down to the
set temperature With standby cooling function, it can maintain the
set temperature in standby mode; it has heating and defrosting
function.
3. It has various early warning functions such as overspeed, over
temperature, unbalance, under pressure and overpressure,
three-stage damping and shock absorption, special combination
damping device, which makes the motor run safely and reliably,
prevent the sample from resuscending and achieve excellent
centrifugal effect. .
4. TFT-LCD true color display, touch control mode, display setting
parameters and operating parameters at the same time, the operation
interface is intuitive, simple and convenient to use; the operation
menu can be provided in multiple languages (Chinese, English).
5. Bio-safety airtight angle rotor adopts silicone rubber integral
sealing ring (EU RoHS 2015/863), which can avoid aerosol spillage
and fully guarantee the safety of workers and laboratory
environment.
6. Rear austenitic 304 stainless steel centrifugal chamber with
all-steel sprayed plastic shell, one-piece stamped steel front face
and three-layer steel protective cover, etc., which are both
durable and durable, ensuring the safety of workers and
laboratories.
7. It adopts mechanical door lock, which is easy to operate and
adapt to various harsh environments. Simply close the door cover,
it will trigger the door lock system and lock the door cover
safely.
8.10 speed acceleration and 10 speed reduction rate control, can
store 16 sets of user-defined programs, can modify the control
parameters of the running rotor at any time, can display the speed
rise curve, centrifugal integral curve, temperature curve.
9. Multi-standard aviation forged aluminum rotor (angle rotor only)
and a variety of polyamide fiber adapters are available.
10. The chassis has casters and carbon steel caster adjustment
blocks to facilitate the movement and level adjustment of the
centrifuge.
11. It has CFDA filing and CFDA production qualification, and has
passed ISO 9001 (2015) certification and ISO 13485 (2016)
certification.
