Stirrer bars for stirring and mixing. These are PTFE coated so they won’t absorb odours, and are available in various sizes and two types – with or without rocker bar (this product). Stirrer bars with the rocker bar are less likely to stick to the bottom of the vessel when dealing with sticky substances, but they make a clicking noise as they stir.
The smallest stirrer bars are perfect to use with our 50ml beaker. The medium stirrer bars will work well with our 100ml Erlenmeyer flask or the 250ml size beaker, the large size are better if you’re mixing in a vessel more than 80mm wide at the base.
At Pell Wall we mainly use these for mixing powders and crystals into liquids, blending liquids together and similar tasks that require an automatic stirrer.
