Closed System for Erlenmeyer Flasks

In the industrial production of biological products, reducing the potential risk of contamination during processes such as liquid transfer and sampling is crucial. Pairing Erlenmeyer flasks with sterile transfer caps and tubing systems can effectively prevent contamination issues associated with open operations.


Jet Biofil has introduced a Closed System for large-capacity Erlenmeyer Flask, made from USP Class VI-compliant materials, manufactured in GMP-standard cleanrooms, and subjected to rigorous tests including extractables studies and biocompatibility assessments. This system can be used with Jet Biofil’s 2L, 3L, and 5L Erlenmeyer flasks, ideal for scenarios requiring high cleanliness level consumables, such as the R&D and manufacturing of biologics including cell therapy, gene therapy, antibodies, and vaccines. It significantly reduces the risk of contamination and allows for easy, sterile, and secure liquid transfer.




Specifications of matching erlenmeyer flask: 2L, 3L, 5L
