The Beckman J2-21 high speed centrifuge is a classic reliable workhorse. Standard features include imbalance detection, auto temperature compensation, selectable breaking modes, auto overspeed compensation, and built in diagnostics. If you are looking to save money on a basic high speed this is the model for your lab and your budget.
Features:
Easy to operate, use of friction reduction system reduces wear and tear on motor and refrigeration system.. Note; result is very efficient system with only 7000 BTU heat output of system
Indirect drive system results in faster acceleration and deceleration resulting in less wear and longer brush life
The operator can set speed, time, and temperature in any order and can change parameters at any time during the run.
Models have a door interlock which prevents the centrifuge door from opening when the rotor begins to accelerate.
