QUARKZMAN – magnetic stir bars for the laboratory

A set of 36 cylindrical magnetic stir bars from QUARKZMAN measuring 30 x 8 mm, intended for use with magnetic stirrers or stirrers with a heating function. It is a basic laboratory accessory that allows quiet and efficient stirring of liquids and solutions in chemistry, biology and other research applications.

PTFE coating

Each stir bar has a magnetic core covered with a PTFE layer, resistant to most chemical reagents and to temperatures ranging from -180°C to 250°C. This construction ensures long-lasting operation without loss of the coating's properties, even with frequent contact with aggressive substances.

Practical advantages

• The smooth surface reduces friction and promotes even, stable rotation
• Easy cleaning after each use
• The stir bars are reusable
• Compact size allows use in typical laboratory vessels, e.g. beakers or flasks

Applications

The product is suitable for chemical, biological and research laboratories, as well as school labs and universities – anywhere a larger number of stir bars in one size is needed, e.g. for parallel experiments.
