Description
Made only of fluoroplastic – without any sealing materials. These filter adaptors for syringes are resistant to virtually all chemicals and do not release any trace elements into the filtrate. The filtering membrane is easily interchangeable after disassembly of the filter adaptor. All these filter adaptors have a very low dead-volume and they can easily be cleaned due to their extremely smooth PTFE surface. Further advantages are: suitable for sterilization and metal-free. These filter adaptors provided with Luer Lock connectors on both sides can be screwed together into multi-stage filters (prefilter, main filter). The non-adhesive surface of the fluoroplastic (PTFE) allows easy cleaning of these filter adaptors. Thus, they have a long working life.
