An 8-piece PTFE magnetic stir bar set in mixed sizes, designed for use with flat-bottom laboratory vessels. Each stir bar is constructed by sealing permanent magnets within PTFE (polytetrafluoroethylene) material for chemical resistance and high-temperature tolerance.
If used with thick, oil-like liquids, the stirring efficiency may be affected. Good Quality Material: Polyethylene tetrafluoroethylene (PTFE) magnetic stir bars are made by sealing permanent magnets in PTFE material can withstand high temperatures.
Component - Each petri dish consists of a flat disc-shaped bottom and a lid. 5 Plastic petri dish with lids. As the petri dish is fragile, be careful when cleaning and taking it, handle it with care.
Test Tube Plugs: Our tapered shape plugs have high elasticity, good insulation and sealing performance, high temperature resistance, acid and alkali resistance, will not dissolve and swell in acidic liquids.
