Cowie Technology : What barreaux magnetics and accessories in PTFE for the laboratory?

Cowie Technology designs and manufactures high-performance PTFE laboratory accessories, purpose-built for demanding chemical environments. The brand is particularly recognised for its magnetic stir bars, but also provides inert, autoclavable and non-contaminating tubing, clamps and instruments for applications in chemistry, synthesis, analysis and biotechnology.

Sixty years of expertise in engineering plastics

For several decades, Cowie Technology has been developing PTFE accessories valued for their chemical inertness, thermal resistance up to 280 °C, and compatibility with solvents, acids and bases. This technical focus makes it a trusted reference for laboratories performing delicate procedures or harsh reactions.

Expertise and areas of specialisation

Cowie Technology specialises in virgin PTFE accessories for critical environments.

Its expertise is reflected in a wide range of magnetic stirrer bars (cylindrical, oval, octagonal and micro), engineered to ensure consistent, stable and long-lasting stirring, even in corrosive media.

Cowie stir bars are autoclavable, resistant to solvents and acids, and ideally suited to dissolutions, syntheses and demanding chemical reactions.

The range is completed by PTFE tubing (moulded from virgin PTFE, non-contaminating, certified to FDA and USP Class VI) and PTFE forceps, ideal for the safe handling of sensitive samples.

These solutions serve chemistry, R&D, pharmaceutical, biology, quality control and analytical laboratories.
