Case Number 098004 - Item Number 254 - Microcentrifuge Tube Spinner
Contact: Geoffrey Pinski
Description: Researchers in many fields routinely work with very small volumes of liquids, which they store in 1.5 ml microcentrifuge tubes (commonly called "Eppendorf tubes"). Upon standing, much of the liquid in these tubes can evaporate and collect around the top and sides of the tubes. This distribution of the contents also occurs when the tubes are mixed. To avoid losing sample, the researcher will briefly spin the tubes in a microcentrifuge prior to opening, collecting the contents at the bottom.
This device is designed as an inexpensive alternative to microcentrifuges. It can hold a number of Eppendorf-style tubes of various sizes (1.0 - 2.0 ml), and will spin these fast enough to settle their contents to the bottom. This device has several advantages over the current practice of using a microcentrifuge, primarily its ease of use, convenience, speed and low cost. The design makes it faster to load and unload, and by operating at lower rpms then a microcentrifuge it will have shorter breaking times. Because of its low cost, each researcher or student can have one readily available, saving the time of waiting for a microcentrifuge to become free.
