J2-21
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.

GMI is
proud to offer a full line brand
carbon fiber composite
replacement rotors for most centrifuge brands
including Beckman, . Such replacement rotors offer substantial value
over ordinary rotors and come with a complete limited
lifetime warranty and guarantee!
They are non-corroding, don't require speed deration over time, and
offer significantly better performance characteristics (your
sample spends less time in the centrifuge), and put less wear and tear on
you centrifuge system!
Call for details on all popular rotor
types such as JA 20, JA 14, JA 10, & Type 45 and see
why your next rotor purchase will probably be your last !
