Hawach Scientific Co., Ltd products

Hawach Scientific EChroma series C8/C18 HPLC Column with type B ultra-high purity full porous spherical silica gel (purity > 99.999%) as the matrix, has an extremely good peak shape and the economy of low-pressure chroma to the graphic column. The packing is the sorbent with C8 or C18 column in HPLC.

Ion-exchange NH2 SPE cartridge is a silica-based bonded to the aminopropyl functional group and is used to extract moderately polar or acidic compounds. NH2 sorbent performs well in a variety of sample matrices and can be used in food, environment, pharmaceuticals, and other fields.

The empty chromatography columns body of the fast separation column is made of medical-grade polypropylene (PP) material, which avoids the dissolution pollution of ordinary PP materials in the separated samples. In addition, the transparent PP material cylinder allows users to visually observe the separation of samples. Hawach Empty columns design enables the fast separation column to withstand pressure up to 300 psi and is safe and leak-free. The Empty Flash Columns have a Luer-Lock standard connector and can be used on various fast liquid chromatography separation systems. The standard Luer-lock end fittings are ideal for quick and easy connection to most of the flash systems such as Biotage, and Yamazen.

The Activated Carbon Syringe Filters are made of acid-washed, high-purity activated carbon for high efficiency and can be used in High-Efficiency Particulate Air(HEPA) filters. Activated Carbon Syringe Filters feature high throughput and no release of harmful substances. Activated Carbon Syringe Filters have a strong adsorption capacity and are designed to adsorb organic vapors, chlorine, decolorizing liquids, and a variety of heavy metals. They are widely used in gas filtration and sterile ventilation.

Cellulose Acetate Membrane Filters, usually called CA membrane filters, are suitable for the filtration of aqueous and many alcoholic media. They have low protein binding capacity, and is thermally stable up to 180°C. We have full range of Cellulose Acetate Membrane Filters, and pore size includes 0.1um, 0.22um, 0.45um, 0.8um, 1.0um, 3.0um,  and 5.0um.  Their diameter covers 13mm, 25mm, 47mm, 50mm, 60mm, 90mm, 142mm, 150mm, 200mm, 293mm, and 300mm. We also can customize the size if you want.

Moderate retention and flow rate are most frequently used in 11 μm daily filtration. It is widely used in laboratory applications to clarify liquids. It is used for the quantitative analysis and separation of precipitates, such as lead sulfate, calcium oxalate, and calcium carbonate.

The crimp cap of crimp top sample vials provides a larger target area to improve the accuracy of the autosampler needle. Crimp top sample vials use certified crimp caps with PTFE/silicone septa to ensure your autosampler operates seamlessly. The crimp cap of crimp top sample vials is guaranteed to work with your device to reduce autosampler malfunction and contamination. Crimp caps provide the tightest seal, reducing the possibility of sample evaporation. All of Hawach vials have super cleanliness and good chemical compatibility and are excellently fitted for autosamplers, OEM service is available.

The MCE membrane pleated filter cartridges consist of the CN-CA membrane and the deflector layer. The filter cover, the shell, the center rod and the flow guiding layer are all made of polypropylene. Each part of the seal is made of non-adhesive hot melt welding technology. The composition is complete and does not include any chemical contaminants. The mixed cellulose membrane filter adopts a hydrophilic mixed cellulose membrane, which has high throughput, high rejection rate, and low protein adsorption performance.

The capsule filter, also known as the integral filter, uses a folded inlet filter membrane with a large filtration surface area and is suitable for the filtration of larger-volume solutions. The outer polypropylene material of this filter, free of adhesives and other chemicals, ensures no contamination of the sample. Filters are available in different pore sizes and can be autoclaved. Hawach filter capsules can choose a variety of specifications and sizes, and can meet a variety of different types. The inlet, outlet, and exhaust outlets are equipped with the standard NPT or saw-genlock interface, which can connect pipes of different sizes through the corresponding swivel joints. The installation is fast and the service is convenient.

The filter bags are a deep filtration, fiber formation, highly fluffy three-dimensional depth, effective removal of solid and soft particles, gradient pore structure. With 100% welded seams.
