After filtration is complete, solution can be stored in the collection reservoir until needed. Individually bagged and gamma irradiated. Convenient and ready to use with no residuals from EtO (Ethylene Oxide) gas to harm your sensitive cell lines. Each unit is considered non-cytotoxic and meets the requirements of the Elution Test, ISO 10993-5, 1999. • Ergonomic collection container Designed with curved sides moulded into the reservoir for easy grasping and holding. • Convenient finger tabs Tabs located on funnel base and storage cap allow for easy removal and tightening. Simply twist for easy handling. • Stacking feature Finger tabs on cap create a broad surface area allowing for convenient stacking of collection reservoirs and minimising the space needed to store bottles.
