Category Of Membrane Filter
MCE Membrane Filter
MCE membrane filter called mixed cellulose ester membrane filter, is ideal for colony counting and sterility testing. It is composed of cellulose acetate and cellulose nitrate, which has made it one of the best membranes in research and analytical applications. It is suitable for sterilizing filtration, air monitoring, and particle monitoring; it is also fit for clarification of aqueous removal and analysis and microbiology analysis.
Cellulose Acetate Membrane Filter
The protein absorption capacity of the cellulose acetate membrane is very low, which is very suitable for aqueous solution and alcohol. Cellulose acetate membrane has improved solvent resistance. The membrane filter can withstand 180℃ high temperature, so it is suitable for hot gas and disinfection by various methods while maintaining the integrity of the membrane.
Nylon Membrane Filter
Hawach Scientific are available in a broad range of pore size and materials such as Nylon. The nylon membrane filter is suitable for use with high PH samples and good for filtration of aqueous biological solutions, alcoholic solutions and other aqueous solutions where protein, peptide, and nucleic acid binding is not a concern. Nylon membrane filter contains no wetting agents, which can greatly reduce the potential for extractable and leachable and provide good chemical resistance with aggressive fluids.
Hawach Nylon membrane filter has good mechanical strength and strong adsorption, it can withstand most organic solvents and most alkaline solutions, especially fit for the filtration of alkaline and solutions. Hawach Nylon membrane is a supported, naturally hydrophilic membrane, which is designed to wet out evenly and retain its superior strength during use in general filtration.
Produced through a proprietary manufacturing process, Hawach Nylon membrane filter meets rigorous quality standards throughout every step of production. And this process generates consistent lot-to-lot binding among the membranes and ensures product uniformity. Low extractable guarantees tests will be clean and pure and lead to more stable results.
Micro-porous Glass Fiber Membrane Filter
It is made of 100% borosilicate glass fiber without binders or with the binder. The depth filter combines a fast flow rate with excellent loading capacity and retention of fine particles. The small diameter fibers endow micro-glass media superior efficiency and dirt holding compared to cellulose and other synthetic media.
The glass fiber (GF) filter membrane belongs to the deep filtration category. Its main use is to be considered as a filter layer by directly putting on a filter membrane.
The GF filter membrane is made of 100% glass fiber without any binders. One of the most important features of it is its high flow rate. It could filter small particles with low resistance. Compared with other fiber materials and synthetic materials filter membranes, the glass fiber filter membrane has higher filtration efficiency and strong dirt holding capacity. Moreover, it can withstand high temperatures of 500 °C, and its large surface area gives it excellent retention capacity.
First of all, The GF filter membrane can be used for pre-filtration of membranes, which could effectively prevent the clogging of the membrane. Due to its high resistance to high temperatures, it can be used for the analytical experiments that require burning and high-temperature gas filtration.
It can be widely used in daily environmental air pollution monitoring because of its large capacity and fast flow rate. When filtering more viscous and difficult-to-filter liquids, such as a serum, usually the multi-layer filtration method would be adopted. There will be a polyester separation layer between the 2-3 layers of filter membranes with different pore sizes stacked., which can facilitate liquid filtration. The uppermost layer is the GF filter membrane.
