Minisart® NML Plus 0.7 µm2 GF Syringe Filter

Minisart® NML Plus with glass fibre filter is optimized for particle-laden aqueous solutions or oils for a higher total throughput. Type 17824 with a particle retention of 0.7 µm can be used for clarification and has a male luer lock outlet. Version K is a non-sterile pack of 50 syringe filters. Units can be sterilized by gamma irradiation or EO.

Non-sterile Minisart® NML Plus syringe filters are supplied in a pouch in one pack. This reduces waste and makes the handling easier whenever the application allows the removal of particles or cells from highly particle-laden liquids under non-sterile conditions. The glass fibre prefilter protects the membrane from early clogging and increases total throughput. The very low non-specific binding characteristics of the SFCA membrane makes the filters a perfect choice for biomolecule solutions. The housing is made of the acrylic resin MBS (Methacrylate butadiene styrene) which has a limited compatibility with alcohols but is free of phthalates. It is glueable, e.g. to tubing, what enables assembly and sterilization by the user. GF and membrane in one filter housing decrease the hold-up volume. If this is no limiting factor a GF-only version is available and can be coupled with a membrane-only syringe filter of choice.
