Electric Centrifuge

$1.00
An Electric Centrifuge is a Class I medical device that uses rapid rotation to separate fluids of different densities, essential in clinical laboratories for processing blood, urine, and other biological specimens. Available in benchtop, refrigerated, microcentrifuge, hematocrit, and high-speed models with fixed-angle, swinging-bucket, or vertical rotors. Speed range 1,000-30,000+ RPM with RCF up to 65,000+ x g. Features include brushless induction motor, digital controls, imbalance detection, lid lock safety, and programmable protocols. Primary clinical applications include separation of serum/plasma for chemistry and hematology testing, urine sediment analysis for microscopy, platelet-rich plasma (PRP) preparation for regenerative medicine, concentration of bacteria for microbiology, cytology fluid analysis, blood banking, and molecular biology sample processing. Critical safety precautions include proper balancing of loads (weight matching), use of sealed rotors for biohazardous samples, regular rotor inspection for corrosion or cracks, never exceeding maximum rated speed, and never opening lid during operation. Essential equipment in clinical, research, and teaching laboratories.

Manual Centrifuge 

$1.00
A Manual Centrifuge (hand-powered) is a non-electric mechanical device for separating fluids based on density, designed for use in field clinics, remote health posts, and developing world settings where electricity is unavailable or unreliable. Operated by hand crank, pull-cord, or foot pedal, achieving speeds of 1,000-4,000 RPM and RCF up to 1,500 x g. Accepts standard blood collection tubes (2-5 mL), microhematocrit tubes, and small centrifuge tubes. Primary clinical applications include separation of serum/plasma for basic diagnostic testing, urine sediment concentration for microscopy, microhematocrit determination for anemia screening, concentration of parasites for malaria and other vector-borne disease diagnosis, field epidemiology and outbreak investigation, veterinary medicine in rural settings, and teaching in resource-limited institutions. Critical safety precautions include meticulous balancing of tubes by weight (absolutely essential), never exceeding maximum rated speed, using appropriate PPE (no aerosol containment), regular inspection of gears and rotor for wear, and proper training of operators. Essential equipment for basic laboratory capabilities in low-resource and field settings.
