Product Introduction：
SG-851-type desktop large-capacity electric centrifuge is the company to meet the needs of various laboratories, carefully designed and sophisticated process technology, large capacity for various types of laboratory experiments by centrifugation of precision instruments。
This high-speed centrifuges used centrifuge rotor rotating centrifugal force generated by the powerful, to speed up the settling velocity of particles in the liquid, the samples of different sedimentation coefficient and buoyant density of the material separate, is a non-uniform system of liquid separation equipment.
Features:
1, attractive appearance, small size, fully functional
2, light weight, large capacity
3, simple, easy to use
4, stable, adjustable speed and can automatically adjust the balance
5, low temperature rise of high efficiency, wide adaptability
6, applies to the hospital laboratory, biochemistry laboratory for qualitative analysis, for plasma, serum, urea, and vaccine manufacturing use.
Handling Precautions
Work in a high speed centrifuge, used to safety and to ensure that the equipment to maintain high precision work, we must do the following：
(1)．Centrifuges used to be placed in a smooth, strong on the counter; large-capacity high-speed low-speed centrifuge and refrigerated centrifuge to be placed accordingly on the ground in a solid, level place. Centrifuge work done, the load balancing, weight error as small as possible, otherwise it will cause severe vibration, and shaft damage turned centrifuge.
(2)．Centrifuge starts, switch knob should be on the low speed position, start and then gradually adjust to the desired value. A work, shall knob again transferred to low-bit work, at high speed block ban on direct start.
(3)．Rotor in the strict inspection before each use if a foreign body and the dirt hole, in order to maintain balance. Turned around and must be kept dry and clean, do not impact abrasion. Such as accidentally dropped, turned to X-ray film should check that no internal injury can continue to use. Turned after each use with warm water (50 ℃ ~ 60 ℃) and neutral detergent immersion cleaning, and finally with distilled or deionized water rinse, soft cloth after drying with hair dryer, wax, dry place.
(4)．Pull all kinds of tube length, strength and stretch are different, should the need to use, the tube can be made of many different materials, such as polyethylene, cellulose, polycarbonates, polypropylene. Use care to ensure the sample, non-corrosive materials, solvent and gradient centrifuge tube and cap components. Expired, the aging, there are cracks or corrosion of the tube by minimizing or spin-down use. Control the use of plastic tube number, pay attention to standard matching. Centrifugal process may open the centrifuge lid, not by hand or foreign body collisions are turned and the rotation of the centrifuge tube.
(5) To ensure safety, be sure to use ground wire
(6)．In the centrifuge process, such as abnormal phenomena, such as the noise and vibration is not normal, should immediately stop checks, not to find reasons not to continue to operate .
(7)．Daily use of centrifuges in the process, every three months the level of response to host a degree of correction for each transfer using 500 million deal with a vacuum pump oil, working 500h should check drive motor carbon brush, preferably with a vacuum cleaner to friction toner remove, if necessary, to replace carbon brushes or commutator with fine sandpaper polish.Should be cleaned about every driver using the 1500h site with high-speed bearings and grease shaft and turned rust-proof joint of fat should be kept painted, do not be long-term anti-rust oil coating oil paper wrap. When not in use should be switched each month low 1 or 2 times, each time 0.5h, to ensure the normal operation of the site.
(8). Be sure to place the centrifuge tube placed symmetrically, and to keep the weight fairly. Things in the open centrifuge to centrifuge lid.
(9). Centrifugal liquid should not be too low boiling point，Should pay attention to internal and external pressure ratio.If it is toxic reagents, but also good ventilation treatment.
