Magnetic stirring bars

For all beakers from 100 to 2000ml capacity. Comprises conical lid made of chemical-resistant plastic with stirrer bearing, two pipette openings and captive PTFE magnetic stirring bar with support shaft. Guarantees gentle running, with no de-coupling of the stirrer bar.

Ultra strong SmCo magnetic core, giving up to 3 x higher torque than conventional magnetic bars, ideal for highly viscous materials and difficult stirring conditions, PTFE-coated and autoclavable with no demagnetization.
New feature: Komet discs and rings for vertical operation, ideal for test tubes.

PTFE coated.

Stirring Bar SATELLITE 70
Extremely strong, abrasion-free and wear-free magnetic stirring bar, bearing on a tripod-construction, especially for the use in stainless steel vessels and in the case of media containing abrasive particles, e.g. sand or sediments, no direct contact between stirring bar and reaction vessel, therefore steady firm, wear-free, chemical resistance comparable to PTFE, recommended magnetic stirrers: 2mag MIX 1 XL and MIXdrive 1 XL.

Stirring Bar SATELLITE 140
Identical to SATELLITE 70, but for larger volumes/vessels, recommended magnetic stirrers: 2mag maxMIX, MAXdrive, FABdrive.

For test tubes or vigorous, eccentric stirring.

PTFE-encapsulated magnetic core (Alnico 5) axially mounted in a guide cage made of PTFE, universal chemical resistance. No shear action on the bottom of the beaker, smooth running in glass beakers also on an uneven bottom. The cage acts like a baffel and thus provides optimum mixing results.

The sealing rings on these bearings ensure a perfect sealing. The ground joint no longer sticks, the danger of breaking is reduced and the cone can be removed easily from the socket. A special gasket made of PTFE and an FPM o-ring which is compressed by a GL screw cap provide a good sealing of the stirrer shaft. This gasket can be exchanged after wearing. Suitable for vacuum, perfect bearing for stainless steel, glass and BOLA Stirrer Shafts.

PTFE-encapsulated magnetic core (Alnico 5), standard magnetic stirring bars, universal chemical resistance. Temperature resistance: from -200 to +250 °C. Cylindrical magnetic stirring bars offer excellent centering and smooth running characteristics.
