The LW Scientific Zip-IQ TT centrifuge is an impressive 6-place test tube centrifuge for spinning blood, urine, and other fluids in 0. 5ml to 15ml test tubes and micro tubes. This attractive unit is very small, conserving valuable counter space in the lab, but also sturdy and heavy with suction-cupped feet for stability. The digital controls allow speed and time to be adjusted with the touch of a finger and will show real-time speed and time remaining. This centrifuge is surprisingly quiet making the lab environment much more peaceful. . . you won't even realize this unit is running. The powerful, maintenance-free, brushless motor spins at 5, 000rpm (2, 500g) producing serum in as little as 5 minutes. Slow the speed to 2, 000rpm (400g) to spin urines in 5 minutes. The auto-brake stops the rotor in 10 seconds, and the lid pops open automatically upon completion. The Zip-IQ TT is the smart choice for any clinic or laboratory.
