Cleanest, Safest, and Highest Performance

Available in PFA, FEP, and the new to the market gamma sterilized
ETFE, our Purillex bottles are manufactured by a stretch blow molding process, adapted for fluoropolymer use by Savillex. This method allows for more accurate and precise molding of the bottle neck and thread - this gives a much more secure seal and eliminates leaks.

Unique Design for Bioprocessing

Purillex bottles feature a wide mouthed 45 mm diameter neck with a GL45 threaded closure. The large, GL45 closure is easy to grip and widely used in the pharmaceutical industry. Additionally, a full 2.5 thread turns gives Purillex bottles greater thread engagement allows the large GL45 closure to be tightened more securely, eliminating the need for a cap liner and ensuring long term seal integrity
