TEFLEX specialises in 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 TEFLEX's PTFE Laboratory Products is pure, virgin material described in the following supplier material guidance: 

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 existing TEFLEX material guidance cites use to approximately 280°C and resistance to embrittlement at liquid-helium temperatures. These are material properties, not operating limits for every finished item. Do not use the approximately 400°C degradation figure as a safe working temperature. Follow the temperature limit specified for the individual product; the PTFE funnel range, for example, states a maximum of 250°C. 

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.

Check Compatibility Before Ordering

Confirm chemical identity and concentration, exposure time, temperature, vessel capacity and any closure or coating limitations. Chemical resistance does not establish a pressure or vacuum rating. The supplier resin purity and compliance statements above do not replace application-specific documentation for a finished product. Request supporting documentation where your laboratory procedure requires it.
