Advantages
High-efficiency filtration
Using microporous membrane with excellent pore size consistency (typically 0.22μm/0.45μm), it has high efficiency in intercepting bacteria and particles, and has been verified to meet HIMA standards to ensure sample purity.
Fast flow rate
The unique membrane support structure and low adsorption design increase the flow rate per unit time by more than 30%, which is suitable for rapid processing of large-volume samples and improves experimental efficiency.
Low protein adsorption
Using low-protein binding materials (such as PES or PVDF) to minimize sample loss and ensure that the target concentration is not diluted or adsorbed.
Strong sealing design
The shell is ultrasonically welded, with strong sealing, not easy to leak, and can withstand high operating pressure (≥3.5 bar), suitable for harsh experimental environments.
Applications
Laboratory sample prefiltration and terminal sterilization filtration
Sterilization of buffer/culture medium in biopharmaceuticals
Removal of particulate impurities in drinking water and environmental samples
HPLC sample filtration
Impurity removal of electronic grade chemical reagents
