Description
BOLA Beaker Liner is a PTFE laboratory accessory with a PTFE-coated Alnico 5 magnet core mounted centrally in a PTFE guide cage. It combines universal chemical resistance with a stable stirring geometry for routine magnetic mixing in glassware. The cage has an outer diameter of 85 mm and a height of 29 mm; the integrated magnetic stirring bar measures 70 mm in length by 9 mm in diameter. Dimensions are matched to low-form beakers of 800 ml and 1,000 ml, so the liner sits securely while the bar couples to a standard magnetic stirrer. Manufactured from polytetrafluoroethylene (PTFE), the cage and coating protect the Alnico 5 core and present an inert surface to aggressive media. This configuration from manufacturer Bohlender supports clean, residue-conscious stirring without metal contact with the process liquid. Net weight is 0,0468 kg. Supplied as one piece for laboratory setups that need a guided beaker liner with defined bar size and broad chemical compatibility in teaching, QC, and research environments.
This article is part of Beakers, in Beakers & flasks.

Questions about BOLA Beakerliner, Ø 85 mm, H 28 mm Stirring bar Ø 9 x 70 mm, magnetic core made
What is this article?
BOLA Beakerliner, Ø 85 mm, H 28 mm Stirring bar Ø 9 x 70 mm, magnetic core made is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Beakers, inside Beakers & flasks, in Labware.
A beaker is an open, straight-sided working vessel with a spout. It is for dissolving, heating and pouring. The graduations are a guide, not a volumetric calibration. Low form and tall form differ in stability and in how easily a liquid splashes.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
