LABORATORY FILTRATION PRODUCTS
SYRINGE FILTER
The syringe filter is a kind of filtration product used to remove impurities from sample solutions before they enters HPLC process, which can prevent impurites from blocking the chromatographic colums, protect HPLC instruments, and prolong the lifetime of chromatographic columns. A syringe filter has to be used togather with a disposable injector, as a whole set of disposing device to filter small-volume sample in labs.

HYDROPHOBIC FILTERS
Hydrophobic filters are mad of medical- grade polyproylene (PP) and equipped with water- repelling PTFE hydrophobic membranes as the gas filtration media. They can withstand high pressure and be used repeatedly, which cater to the purposes of ventilation in small-scale fermentation tanks and bioreactors, protection of vacuum pumps, and aseptic air exchange in culture medium storage tanks.
STERLIZING FILTER
This disposable sterilizing filter is made of medical-grade polypropylene material. It is in single package with paper seal easy to tear. It adopts EO (ethylene oxide) sterilization process which is suitable for sterilization and filtration of lab bio-fluids, culture media, and/or media additives, it has no het source, no endotoxin, no DNA enzymes in the filtration process, and thus has high stability and compability.
STERILIZING FILTRATION MEMBRANE
The disposable sterilizing filtration membrane use EO (ethylene oxide) for sterilization. It is in single package with paper seal easy to tear, including two surface conditions- plain and grille- to choose. It can be used for lab sterilization tests.
MICROPOROUS MEMBRANE
Microporous Membrane is a kind of porous membrane filtration media made of fibre or polymer materials. Due to its advantages of uniform pore-size, high porosity, no pollution, etc, it can be applied for purification of water solutions, air, liquors and oils, sterilization and filtration of biologics testing and analysis of contaminations, pretreatment of seawater desalination, lab filtration,etc, providing broad services for pharmacetuicals, electronics, foods, helath cares, metallurgies, chemicals, machineries and other industries.
PES membrane is imported originally from USA, and with features of strong hydrophilic, high flow rate, high resistance to acids and /or alkali, low soluble substances and high strenght, it can be widely applied for the filtration and sterilizing filtration in fields of bio-chemicals, testing and analysis, pharmaceuticals,etc
This kind of membrane is with features of multi-application and high-temperature resistance. With high strengths, good flexibility and chemical compatibility, it is designed to meet the demanding requirements of chemicals filtration, and is the ideal and economic substitutes for PTFE. This kind of membrane also posssess good heat-resistance and chemical stability, is able to stand acids, weak alkalis , various bic, and is a kind of new-type the filtration membrane suitable for not only sterilization, micro-particle removing of liquid solutions, but also dehumudify, sterilization and dust-removing of gas substances.
These PP filter membranes are made up of ultrafine PP fibers that are bonded togather through hot melting to produce a type of deep filtration membrane. It uses food-grade PP as raw material during production, ignoring the use of any additives throughout the process. It exhibits stable physical and chemical properties, excellent compatibility, high porosity, high pollutant- carrying capacity, satisfactory pressure resistance, and the capability to undergo backwashing and withsand high-temperature sterilization. These properties make our PP filter membranes popular options for pharmaceutical, chemical, food, and beverage applications.
These CA filter membranes are special membranes processed from cellulose acetate and additives using membrane technology, boasting outstanding acid and alkaline stability, corrosion resistance, high mechanical strenght, and commendable damage resistance. These high-temperature stable membrane gain extensive application in the fields of chemical engineering,pharmaceutics, and environmental protection due to its properties.
These RC filter membrane are produced from pure cellulose or cellulose derivatives, giving them decent chemical resistance, good thermal stability, low affinity for proteins, high mechanical strength, and excellent flexibility. They are popular in the food and beverage industry, and are mainly used for filtering biological products,as well as in various environmental and industry filtration processes, among other use cases.
This membrane is made of alkali-free ultra -fine glass fibre, with no adhesives. It shows chemical inertness and advantages of high flow rate, high strenght and high filtration efficiency. It can remain sub-micro particles, and stand high temperature of 500°C, suitable for testing and analysis of large-and -middle -volume TSP and PM10. The products can be widely used for analysis and testing of air pollution under various conditions.
