Magnetic-Stirrer-Table details

CerCell offer Standard (12 magnets) and Compact (8 magnets) and Ultra (8 magnets) mechanical Magnetic-Stirrer-Table (MST) for adaptation to various Process-Control-System (PCS) servo motor's. Able to transfer comprehensive amount of power though depending on the particular servo motor capacity.

A popular agitation setup is based on the Biostat designed ID39-B adapter standard and PowerGrip WK-21 rubber coupling. It takes only a few seconds to exchange the servo motor from your Stirred-Tank-Reactor (STR) and mount on the MST.

 The small Applikon ID25-A nose drive fits any CerCell MST mounted with ID25A adaptor. The ID25A nose/adapter is widely used by several PCS suppliers (Applikon, DASGIP, Broadley-James). The exchange of servo motor from STR to CerCell MST takes only few seconds. Servo motors rated higher than 40 watt at low RPM can drive the MST.

Latest use of NEMA.23 servo motors gives a compact solution able to agitate up to 13 liter SUBs easily. Perseus Cadmus from with ID39-B adapter kit mounted on green MST-C.

The Eppendorf ISS ESM60C or ESM80motor when mounted with adaptor PN42607 fits any MST.

Perseus with geared Papst servo motor (from with ID39-B adapter kit mounted on MST-U driving the 3,2 liter CellVessel.

MOOG model C34 servo motor used by NBS with the short Guardian 18PG rubber coupling which fits the CerCell MST with the appropriate adapter. Also MagMotor model C21-K175 motor as used by NBS may easily be mounted with the ID39-B conversion kit in order to fit the standard MST and SUBs or SUFs from CerCell.

Four MST-U with white POM SUB-Support-Square (SSS) foot. Mounted on MST-U the 3 litre SUB driven by Kollmorgen servo motor.
