A low contamination bottle for sampling, storing, and transporting of chemical samples includes a bottle portion defining an internal volume and having a threaded neck, and a cap portion provided with threads that engage the threaded neck of the bottle to provide a fluid-tight seal between the internal volume of the bottle and the ambient environment. The bottle has a flexible sidewall portion that permits the reduction of the internal volume to allow a liquid sample to be drawn into the bottle portion by a suction or vacuum process. Both the bottle portion and the cap portion are made from a material selected from the chemical resistant group consisting essentially of hydrocarbon polymers and fluorocarbon polymers, where the material generates less then 1 ppb of metal contaminants and 1 ppm of leachable anionic and organic contaminants. The flexible sidewall portion of the bottle portion has a minimum thickness of 0.2 mm such that the low contamination bottle meets all safety requirements for the transport of hazardous chemical samples.

[ We claim:] [1.] A low contamination bottle for the storage and transport of chemical samples comprising:a bottle portion defining an internal volume, said bottle portion having vertical axis having proximal and distal ends, said bottle terminating at said proximal end in a base portion and being formed at said distal end with a shoulder portion, said bottle further having a flexible resilient sidewall portion formed concentrically about said vertical axis with pleats which permit the reduction of said internal volume in response to a compressive pressure applied to said shoulder and said base and responsive, upon a release of said pressure, to recover said reduction of said internal volume, said bottle portion having a threaded neck, said bottle portion being made from a material selected from the group consisting essentially of hydrocarbon polymers and fluorocarbon polymers, said resin generating less than 1 ppb of leachable metal contaminants and 1 ppm of leachable anionic and organic contaminants, said flexible sidewall portion having a minimum thickness of 0.2 mm; anda cap portion provided with threads that can engage with said threaded neck of said bottle portion, said cap portion being made from a resin selected from the group consisting essentially of hydrocarbon polymers and fluorocarbon polymers, said resin generating less than 1 ppb of leachable metal contaminants and 1 ppm of leachable anionic and organic contaminants.
