Micro-Stir® and Biostir® Magnetic Stirrers, Wheaton

Supplier: DWK Life Sciences
BioStir®
W900703-A W900701-A W900702-A W900700-A
Designed for a variety of cell culture applications and for use with suspension culture flasks

Both the Micro-Stir and the Biostir stirrers have three computer-controlled modes of operation to optimize growth of cells. The constant speed mode is useful for suspension cultures and features a soft start to a constant stirring speed. The interval start mode can be used for attaching cells to microcarrier beads. This mode turns the stirrer on and off using the soft start and stop for a number of cycles, after which the stirrer runs at a constant speed which may differ from the speed used to attach cells. The two-speed stirring mode, also useful for microcarrier applications, slowly starts to a set speed, holds the speed for a user-defined period, and then softly changes to a final constant speed.

Micro-Stir stirrers are ideal for cell culture applications requiring exceptionally slow speeds, gentle mixing, and low heat transfer. The gradual stop rotation facilitates bead and cell attachment by allowing cells to settle and attach and to draw off and replenish any spent media.

Biostir stirrers feature a powerful alnico magnet for increased efficiency and a smooth-running DC motor that provides uniform speed while reducing heat transfer to the medium.

A DC motor and an easy-to-read display provide precise speed control for reproducible results. Units can be used in environments with CO2 and non-condensing humidity.

The remote control allows all stirrer functions to be controlled and monitored without opening an incubator and disturbing the incubator contents. The remote control comes with a 3.7m (12') cord.

Ordering information: Culture flasks sold separately. For Wheaton Celstir® suspension culture flasks, see 62401-900 series.
