Stuart stirrer US151 is a robust model with a stainless steel top plate which does not produce eddy currents like aluminium and so ensures a very powerful coupling and stirring action. Powerful magnets and motor give stirring speeds up to 2000rpm and is capable of mixing large volumes (up to 15 litres). The compact shape takes up less bench space and makes storage easier.The units also include BioCote® antimicrobial protection which reduces the presence of odour and stain causing microbes such as bacteria mould and fungi on the product surface by up to 99.99%. Formulated from silver ion additives BioCote® provides built-in antimicrobial protection to support a more hygienic laboratory environment.Please Note: BioCote® technology does not protect users or others against disease causing bacteria germs viruses or other harmful organisms. This technology is not a substitute for good hygiene and/or cleaning practices.Technical Specifications:Top Plate Dimensions: 150mm x 150mmTop Plate Material: Stainless SteelStirrer Power: 50WLow Speed: 100rpmHigh Speed: 2000rpmOverall Dimensions: (W)172mm x (L)248mm x (H)122mm It has an integral fitting for a retort rod and the bottom of the magnetic stirrer is shaped to allow a retort base to slide underneath the unit if required so saving further bench space.The unit is supplied with 2 x 25mm PTFE coated stirrer bars.
