The syringe filters are a fast, convenient and reliable filter tool used in the laboratory. It is beautiful and light in appearance and high cleanliness. It is mainly used for sample prefiltration and clarification of removing bacteria and filtration of particles, liquids, and gases. It is the first choice for filtering HPLC and GC small quantities.
Hawach produces three series of syringe filters: WINSTAR series syringe filters, FILTSTAR series syringe filters, Sterile series syringe filters.


Hawach Scientific Co., Ltd filter cartridges divided into big/small pleated filter cartridge, membrane pleated filter cartridges, metal filter cartridge, micro fiber pleated filter cartridge and others. Our filter cartridges are widely used in foods before a filter cartridge is produced, it goes through a series of cleaning processes and filter integrity tests and finally drying 24 hours before packing out. Our filter cartridges are widely used in foods, pharmaceuticals, chemicals, and electronics.


The filter housings can be quickly filtered and have high filtration accuracy and easy cleaning. It has the advantages of less adsorption, no media shedding, no dead angle, no leakage, corrosion resistance, and acid and alkali resistance. It is an ideal filtration equipment for food, pharmaceutical, chemical, electronics and other fields.


Hawach filter bags are produced by heat-sealing or car sewing using porous short fiber non-woven fabrics or nylon woven mesh. Filter bag has a deep filtration structure and good integrity. Filter bags have the advantages of large filtration flow, low resistance, long service life, low cost and easy operation.


The shell of the filter capsules are made of high-temperature polypropylene material, and the filter cartridges inside are made of hot-melt welding with folded filter cartridges. The product does not contain adhesives and other chemicals. For filter capsules, different filter membrane and different pore size can be selected and autoclaved. It is suitable for filtering 1-20L low-dose liquids, gases, or industrially valuable small-volume liquids.


Filter membranes we have two types: round disc membrane filters and roll type membrane filter, both of them can be used for filtration and sterilization of liquids, gas, and other samples. Filter membranes remove all micro-organisms and particles reliably, without any effects on the ingredients during the whole process.
We are available in a broad range of pore size and materials such as PTFE, PVDF, Nylon, MCE, CA, PES, GF, PP and etc. OEM Service and customized size are also available.


Hawach Scientific Co., Ltd provides qualitative and quantitative cellulose filter papers. It can meet the needs of different levels of purity, hardness, flow rate, loading capacity, and chemical resistance for our customers. For the qualitative filter paper, it includes standard filter papers and wet-strengthened filter papers. The qualitative filter paper is used to identify the properties of substances in qualitative analysis. Wet strength qualitative filter paper contains a small amount of chemically stabilized resin, thereby enhancing the wet strength.


Hawach SPE cartridges are used in the pretreatment section of the sample being analyzed. When it is used for separation, the solution is generally left behind by gravity or with a vacuum device to speed up the separation. Our SPE cartridges are divided into silica gel, polymer, adsorption type, the special cartridge according to matrix type. SPE cartridges consist of medical PP empty tube, medical PE sieve plate, and a fixed adsorbent.


Flash column is a general consumable for flash chromatography method analysis, the flash chromatographic method commonly is used for isolation of a single chemical compound from mixed samples. Hawach Scientific special produced high purity stationary phased packed flash column with the full range of size supplied to global users. The column cartridge made from medical grade virgin PP material and PE frits. Column available in prepacked and empty flash column(solid sample load cartridge).


The filter manifold is used for liquid filtration. Hawach Scientific Co., Ltd single solvent can be passed through a single sample, solvent filter, and reasonable design. Vacuum filtrations are equipped with a separate valve that can filter single or multiple samples simultaneously, saving a lot of test time.


Hawach Scientific special produces and supply prepacked and empty HPLC column to global market and stationary phase with full range of material available such as C18 universal, C18 low PH, C18 aqueous, C8 universal, C8 low PH, C8 aqueous,C8-fluorine, Phenyl, NH2, CN, Diol, SiO2 ,Polar-RP etc. Our HPLC column with high column efficiency andexcellent shape peaks and low pressure for a longer lifetime, especially the universal C18 column which equivalent to brands like Waters, Agilent and GL Science.
