Researcher Steamer – Autoclavable, Gamma Irradiated, Hollow Fiber Cartridges – Ready to Use – Easy and Reliable.

The Researcher Steamer hollow fiber membrane products incorporates our latest glycerin free low extractables, heat resistant modified polyethersulfon membrane technology. All Steamer products are gamma irradiated and ready to use without any tedious pre-rinse. The Steamer HF cartridges are the product of choice for perfusion/ATF applications. They can be repetetively autoclaved in an ATF perfusion unit or as a stand alone HF cartridge or in a tubing assembly. Please contact us for the correct Steamer product for ATF 2-10 models. experttalk@WaterSep.net.

The extractables level for the Researcher Steamer is approximately 80x less than a glycerin conditioned membrane. (Please see graph below). After a quick buffer conditioning The HF cartridge is ready to use to be used or autoclaved. For autoclaving directions, please see the Steamer Validation Guide.

The Researcher Steamer hollow fiber cartridges are positioned between the laboratory scale Explorer Green and the full pilot scale Investigator Green cartridges. The membrane surface area is between 420 cm2 for the Researcher12 and up to 1,715 cm2 for Researcher41 and are the perfect choice for perfusion applications, small aseptic processes and preparative biopharmaceutical work with sample volumes between 400 ml up to 8000 ml.

The Researcher Steamer cartridges are available with molecular weight cut-off from 3K to 750 K and 0.1 um, 0.2 um and 0.45 um and with the same path length as all other WaterSep HF cartridges which makes scale up/scale down exact and predictable.

Typical single use applications for The Researcher Steamer products are:

  • cell perfusion with an ATF system or conventional pump operated perfusion systems. Bioreactor and Steamer hollow fiber assembly can be autoclaved simultaneously.
  • aseptic/sterile applications, where autoclaving is required.
