Anotop syringe filters can be used with most organic solvents and aqueous materials and are suitable for sample volumes up to 100 ml. The distinctive hexagonal housing is manufactured from pigmentfree polypropylene to eliminate sample contamination. No wetting agents or adhesives are used in the manufacturing process. Anotop syringe filters contain the proprietary aluminabased Anopore membrane and are supplied in three pore sizes. Glass microfiber prefilter versions are available for difficulttofilter samples.
