Magnetic stirring bars

The cylindrical LABSOLUTE® magnetic stirring bars have a smooth surface. The PTFE coating makes them particularly resistant to chemicals and temperatures.

The LABSOLUTE® stirring bar retrievers in the lengths of 150, 250 and 350 mm are suitable for removing magnetic stirring bars from vessels of all kinds. They have a strong permanent magnet (Alnico 5) with a 10 mm diameter. Due to the PTFE coating the stirring bar retrievers are particularly resistant to chemicals and temperatures.

The set of LABSOLUTE® magnetic stirring bars is a perfect assortment of the most common sizes for almost all applications. The cylindrical, smooth, PTFE-coated stirring bars come in a solid box with a transparent, hinged lid.

The set consists of the following 10 stirring bars: 1x 15 x 6 mm, 2x 20 x 7 mm, 2x 25 x 7 mm, 1x 30 x 7 mm, 2x 40 x 7 mm, 1x 50 x 7 mm and 1x 60 x 7 mm.

Circular, smooth and PTFE-coated. Packaging size: 10 pieces

PTFE-encapsulated stirring bar retriever with strong permanent magnet (Alnico 5), universal chemical resistance. For the removal of stirring bars from aggressive liquids, prevents loss of stirring bars. Lower end diameter 10 mm.

Universal alternative to oil bath

The reaction block allows syntheses to be carried out in round flasks at temperatures of up to 250 °C. As a result, with this system, oil as a heat transfer media is made redundant and your lab is a safer place. The reaction block ensures safety at work and prevents oil baths and heating mantles from overheating in your lab. The messy oil clean-ups that results from changing oil or removing flasks from an oil bath will be eliminated. Injuries and burns from hot oil will never happen again. Uniform mixing is also guaranteed because there is no interference to the magnetic field from the aluminium blocks. This system ensures optimal heat transfer from the heating plate directly into the medium.

• Universal model

Safety cover for LLG-Reaction block system to protect against broken glass and for heat insulation.

Encapsulated in PTFE. Oval. Ideal for round bottom flasks.

PTFE-coated. Cylindrical. Round, smooth surface. Versatile. Autoclavable. Further sizes available on request.

Triangular. PTFE-coated. Wedge-shaped, ideal for dissolving solids and re-suspending sediments due to scraping action. Angular surface produces high turbulence, even at low stirring speeds.
