Cowie are the worlds leading specialist for the design and manufacture of PTFE Laboratory Products, including PTFE beakers, PTFE Bottles, PTFE coated magnetic stirring bars and PTFE Stirring shafts.

PTFE used in the manufacture of COWIE® PTFE Laboratory Products is pure, virgin material which conforms to FDA and USP Class VI requirements. PTFE is the material of choice for: 

Chemical Resistance 

The chemical resistance of PTFE is almost total over its working temperature range. Reaction is limited to some compounds with free electrons such as sodium in liquid ammonia and some fluorine compounds at high temperature and pressure. Halogens will penetrate PTFE but without apparent reaction. 

Thermal Stability 

The thermal stability of PTFE is outstanding. The material can be used to ca. 280°C yet there is no embrittlement in liquid helium. Thermal degradation does not commence until about 400°C. PTFE does not melt to form a liquid phase. 

Insolubility & Purity 

The PTFE we use conforms to USP Class VI and FDA requirements and is intrinsically pure and contains no additives. PTFE is insoluble in all known solvents except under extremes of pressure and temperature and will not contaminate media by dissolution. 

Sterilisation 

PTFE can be sterilised by all usual means except gamma radiation.
