The Researcher membrane hollow fiber cartridges are
positioned between the laboratory scale Explorer and the full pilot scale
Investigator cartridges. The membrane surface area is between 420 cm2 for the
Researcher12 and up to 1,715 cm2 for Researcher41 and area the perfect choice for
scale up/scale down studies and preparative biopharmaceutical work with sample
volumes between 400 ml up to 8000 ml
The Researcher 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. The Researcher re-use cartridges can be sanitized and
cleaned in 0.5-1.0 N NaOH, and stored in 0.1 N NaOH between usage.
Recommended batch volume for Researcher12 is 0.4L- 2L
with a permeate flow rate of 1.4 L/h.
