Filtration system 

  1. 1. Liquid filtration system 100% pure cotton fibre - high levels of the most pure form of cellulose fibre, alpha cellulose, combined with ultra-pure water yields media with high levels of absorbency and moderate tensile strength. This material is best suited for applications that are extremely sensitive to the presence of interfering substances. Blends ofcotton and wood fibre - addition of wood fibre adds greater versatility in the development of flow rates and strength, which results in a more economically produced media. Cellulose fibres derived from wood, can contain traces of naturally occurring organic and inorganic compounds that may cause interference in sensitive reaction systems. For this reason, cotton/wood blends are best suited for use as absorbent padding for collection of excess reagents,wash solutions or sample in self-contained reaction units or other applications that are less sensitive to the presence of interfering substances. Binderlessglass micro-fibre - manufactured from 100% borosilicate glass fibre with no added binders or other chemicals that would cause interference in sensitive reaction systems. The unique characteristics of glass fibre media make it ideal for use in applications requiring rapid flow rate,fine particle retention or high loading capacity. Glass micro-fibre with binder - a small amount of latex or PVA binder is added during manufacture to yield a stronger sheet that still retains the same high flow rate and fine particle retention characteristics of binderless glass fibre. The presence of the latex and PVA binders limits the use of this material to less sensitive applications. Specifications given in the catalogue are typical values that fall within a defined range and for this reason observed values may vary slightly. Used filter paper must be considered as hazardous waste and disposed of accordingly in an environmentally friendly manner. Product samples are available on request to assist in determining the Filtech® grade that is most suitable for your application.
