PFA Bottles

PFA bottles are a high quality, temperature resistant solution for filling, storage and transport of pharmaceutical products. PFA is short for Perfluoroalkoxy alkanes, a highly pure and robust advancement of the common material PTFE.

GMPTEC offers Purillex® bottles made by Savillex, which are completely made of high-purity PFA. These bottles fulfill even highest requirements and assure the quality of your products!


Information about PFA Bottles

GMPTEC is the German-speaking partner of Savillex and offers a range of high-purity fluoropolymer bottles and vials under the brand name Purillex®. These bottles excel due to their very high temperature and chemical resistance, which cannot be archived by alternative products.

Depending on the application and specific requirements, there are three different materials available:

  • PFA – autoclavable
  • FEP – autoclavable
  • ETFE – gamma sterilizable

Purillex® PFA bottles are especially suitable for critical applications and processes, in which valuable drug substances and final products are being filled and afterwards frozen by using liquid nitrogen. Due to their enormous temperature resistance of up to -200 °C to +260 °C, these bottles can be frozen without any problems. They don’t have any negative impact on the product quality and help to prevent costly loss of produced batches. The bottles and vials can also be used to keep and storage retention samples. This assures that the sample is not affected by uncertain factors, which could lead to the corruption of test results.

All Purillex® bottles made by Savillex are produced in a special stretch blow molding process. This innovative production process allows to reach a very high product quality and manufacturing accuracy. All bottles have a non-sticking surface and a smooth transition to the bottleneck, which allows to completely empty the bottle. This also means that the bottles can be cleaned very effectively. This is a very important factor, especially when the fluoropolymer bottles are being used multiple times, because it minimizes the risk of contamination from residues.

Both, the bottle and closure, are made from the exact same PFA material. This assures that there is no material mix when using Purillex® bottles, like it’s the case for almost every other bottle with closure. The closure of the Purillex® bottles has more threads than a regular bottle, which increases the process safety and seals the bottle perfectly. Their special design and the precise manufacturing process eliminate the need for an additional gasket within the closure.

Purillex® bottles made of PFA stand out due to their extreme temperature resistance. They cover a material working temperature range of -200 °C to +260 °C. This is much higher than bottles made of polycarbonate or PETG, which will fail much earlier and therefore cannot safely be used for certain processes. The melting point of PFA material is above +300 °C.

Especially when the bottles need to be autoclaved before using them, the material PFA is the first choice due to its abilities and resistances. PFA bottles are also suitable for dry heat sterilization at up to +250 °C for two hours.

The used PFA material is extensively tested, certified, complies to USP Class VI and a vast number of other regulations. The bottles have outstanding leachable and extractable values and are nearly unbreakable due to their robust design. Validation data and test reports are available upon request.

Purillex®PFA bottles are also available as pre-sterilized by autoclaving and ready-to-use. The sterilization process has been validated and allows to certify a sterility assurance level of 10-6. All batches of pre-sterilized bottles will be tested for bioburden, endotoxins according to USP <85> and particulates according to USP <788>. Each bottle is individually double bagged.

Savillex has performed extensive drop tests for all Purillex® bottles in comparison to materials like PETG and polycarbonate. The test results can be provided upon request.
