Spider - accelerating membrane performance screening

Spider front

The Spider is a high-throughput dead-end filtration module designed to revolutionize liquid filtration workflows. Capable of performing up to 8 or 16 simultaneous filtrations (depending on the model), the Spider drastically reduces experiment time while ensuring reliable and precise results.

Built from robust stainless steel, the instrument is compatible with both aqueous and non-aqueous feed solutions, making it a versatile and essential tool for modern membrane laboratories.

The Spider workflow is simple: membranes are placed inside the sample holder, the chamber is sealed, and the feed reservoir is filled with the selected solution. By applying the desired pressure, individual permeates are collected in separate bottles for analysis, while the remaining retentate can also be retrieved.
