This firm has developed the bepure process, in which different types of high-purity cellulose are crosslinked to form a structure that does not require the addition of any inorganic material, even for sterile filtration duties. BecoPad P (photo) is characterized by unparalleled purity, with ion and endotoxin contents hardly detectible, says the manufacturer. The new range is available as a low or high cationic version. The filters are said to have a lifetime up to 20% longer than conventional sheets. Rinse volume is reduced by 50%, which results in significant cost and time savings, says the firm. — E.
