I have an International Centrifuge model HT. This is a powerful machine; capable of variable speeds up to 17,000 rpm and 34,000 xG. It comes with a rotor that holds 8 standard 50 ml tubes. It has a timer for up to 120 min. or continuous operation. The control panel meter measures amps or rpm, switchable. Heavy steel rotor chamber insures operator safety. Weight: 115 lbs.; power 120v., 12A.
This is a rugged, dependable benchtop unit; excellent for high-speed applications in biological research labs; or for difficult to separate materials like paints, greases, and secret recipe barbecue sauces.
It offers forces normally available in much more expensive floor models. The 1988 Fisher Catalog listed this model for $5760. My price is $500 + shipping.
