【7 SHAPES OF STIR BARS & 1 MAGNETIC RETRIEVER FIT ALL YOUR NEEDS】This SOGA LIFE stir bar set is a solid professional equipment. Stirring rods of various shapes for greater turbulence and stronger vortex, 1pc recycling retriever for stir bar retrieval after mixing is done, free from polluting solvents.
【TEFLON PTFE MATERIAL】The stir bar is coated with Teflon (PTFE), which can be used with corrosive chemicals, and helps reduce friction and wear to the lowest while stirring the liquid.
【NON-ADHESIVE】Built in pivot ring, the SOGA LIFE magnetic stir bar will perfom its job well and spin in the solvents smoothly and balantly, free from vibration and adhesiveness with solvents.
【WIDE-RANGE TOLERANCE OF TEMPERATURE】The magnetic stir bars maintain good mechanical toughness between 196℃～250℃, still performing well with 5% elongation even if the temperature reach its limit of -196℃ or 250℃.
【WIDE APPLICATION IN ALMOST ALL SOLVENTS】The magnetic stirrer can be used in most solvents, with high inertia as well as strong acid and alkali resistance. It is also corrosion resistant, non-adhesive and non-toxic.
