Magnetic stirring bars

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.

Cylindrical, PTFE, white.

For magnetic stirring bars up to 80mm long.

• The pivot ring reduces the contact surface and enables the stirrer to adopt the optimum position
• For vessels with slightly uneven bottoms
• High turbulence even at low speeds

Smooth surface. With rings and permanent magnet AlNiCo V core.

Useful extension to the existing range of Bola stirrer shafts. The additional blades can optionally be fixed in your preferred position on every stirrer shaft with diameter 8,10 or 16 mm (a flat spanner is included). The stirrer blades are entirely made of PTFE, the mounting devices are made of a special PTFE-compound. A high chemical and thermical (-200 to +250 °C) resistance is assured. This "building block system" allows the user to define a stirrer of their own special requirements.

Multi-faceted shape provides greater surface area and added turbulence for more vigorous, thorough mixing when compared to the smooth surface of cylindrical bars.

• With pivot ring for better mixing conditions
• Alnico magnet encapsulated with Teflon^® brand PTFE coating
• FDA Grade, USP Class VI
• Good chemical compatibility
• Autoclavable
• Manufactured in a registered ISO 9001:2015 facility

Multi-faceted polygon shape with increased surface area creates added turbulence relative to similar sized, smooth cylindrical bars to provide thorough mixing.

• Alnico magnet encapsulated with Teflon^® brand PTFE coating
• FDA Grade, USP Class VI
• Good chemical compatibility
• Autoclavable
• Manufactured in a registered ISO 9001:2015 facility

PTFE coated.

Cylindrical, with pivot ring. For vessels with slightly uneven bottoms. Alnico V magnetic cores. Maximum operating temperature 270 °C.

PTFE coated.

• Steady spinning position
• Good stirring action

With pivot ring. PTFE-encapsulated magnetic core (Alnico 5). Universal chemical resistance. This shape provides a bigger surface area and a very steady spinning position with additional turbulences. Temperature resistant from -200 to +250 °C.

• Can be bent as required (the shape is permanently retained
• Round ends

Round profile. Made of a highly magnetic material (rare earth samarium-cobalt) with PTFE coating.
