Centrifuge

$1.00
 A centrifuge is an instrument that uses rapid rotation to separate components of a liquid mixture based on density. In clinical and laboratory settings, it is indispensable for preparing blood samples (serum, plasma, cells), concentrating urine sediment, and processing microbiological specimens. Key specifications include maximum relative centrifugal force (RCF) and rotor type (swinging bucket or fixed angle). Safe operation is paramount and hinges on perfect load balancing, using securely sealed tubes, and never overriding safety lids. Proper cleaning after spills and regular rotor inspection are essential for preventing equipment failure and biohazard exposure. It is a fundamental piece of equipment for sample preparation across all disciplines of laboratory medicine.

Roller Mixer

$1.00
 A Roller Mixer is a laboratory instrument that provides continuous, gentle, end-over-end agitation of samples in tubes or bottles. Its primary clinical function is to prevent clotting in anticoagulated blood samples and to ensure consistent mixing for coagulation studies and immunoassays. Featuring adjustable speed and timer controls, it is designed for quiet, reliable, and continuous operation. Key to its safe and effective use is ensuring tubes are properly sealed, loading is balanced, and any spills are cleaned promptly to prevent contamination. It is a fundamental tool for maintaining pre-analytical sample integrity in clinical and research laboratories.
