HAWACH focuses on the timely delivery of high quality, consistent and robust products, and ensuring business continuity for its customers.

HAWACH flash column

Flash column is a chemical separation technique used to purify chemical mixtures. Because it is a purification technology, the process is also referred to as flash purification. The features of being fast, easy to operate, time-saving and labor-saving make it popular in the industry.

HAWACH owns three series of the flash column with different focuses to meet more requirements, for instance, the PureFlash series is for the high-end market and DepuFlash series for the low-end market. The StarFlash series is the silica gel columns for general usages.

In addition, various specifications are available to make all customers get they need, for instance, the adsorbent can be imported and domestic and the materials take medical grade PP or PE, or any material specified by customers.

What Is Filter Cartridge?

The filter cartridge is a term with the function of filtering and purifying.

Application
-Pharmaceutical industry: pre-filtering of various antibiotics and other liquids
-Food and beverage industry: filtration of alcohol, mineral water and drinking water
-Oil industry: oilfield water injection filtration
-Electronics industry: high purity water pre-filter
-Chemical industry: filtration of various organic solvents, acids and lye
-Metallurgical industry: filtration of hydraulic systems of rolling mills, continuous casting machines and filtration of various lubrication equipment.
-Textile industry: purification and uniform filtration of polyester melt in the drawing process, protection and filtration of air compressor, degreasing and dehydration of compressed gas.

Service life
The service life of filter capsule varies based on the raw materials adopted. Impurities in the water will clog the filter element as time goes by, and the activated carbon filter will absorb saturation.

Therefore, the PP filter cartridge needs to be replaced in 3 months, and the activated carbon filter bag needs to be replaced in 6 months. As the hollow fiber can not be cleaned, it is generally placed at the back end of PP cotton and activated carbon. Otherwise, it is easy to block.

As the end of the water purification equipment, it needs to be replaced in 1-2 years. Ceramic filter housing can generally be used for 10-12 months, and quality ceramic filter cartridges can be used for 3-5 years or even longer.

Types and Maintenance Of Sample Vial

Types of Sample Vial

Hawach scientific are available in wide selection of types and complete accessories, including crimp top sample vial, headspace vial, storage vial, snap top sample vial, septa, and cap for screw thread sample vial, screw thread top sample vial, septa and cap for crimp top sample vial and so on. Besides, sample vial provides with flat or rounded bottom designs.

Store samples in storage vials can eliminate leaching of ions while maintaining a consistent pH for the life of your sample. Compared with crimp caps, snap top sample vials are generally more convenient and can be easily applied and removed by hand.

Maintenance of Sample Vial

Sample vial provided by our company consists of two kinds of glass colors, one is clear, and another is amber. Caps are lined with PTFE/silicone for excellent seal-ability and chemical resistance, which can assure the maximum level of seal security.

Storage glassware manufactured in borosilicate glass, which can protect samples from evaporation and oxidization. In application, a secure seal and the cap should be properly aligned. After using, sample vial should be immediately cleaned and dried, then placed in storing box.

A Brief Introduction And Usage Of Syringe Filter

Syringe filter is made of transparent grade polymer material polypropylene (PP), which is used together with a disposable syringe.

It is a fast, convenient and reliable small volume sample filtration treatment device used in the laboratory. It is mainly used for pre-filtration of samples, sterilization filtration of laboratory biological fluids, media and media additives.

Syringe filter is aesthetically designed and high┬аcleanliness, as it does not require membrane change and cleaning filters, eliminating complicated and time-consuming preparations.

It is the preferred method for filtering small samples of HPLC and GC, and is often used in conjunction with disposable syringes. The filtration diameter is 4 mm to 50 mm, and the treatment amount is from 0.5 ml to 200 ml.

Usage

There are many usages and the main usages can be summarized in the following:
1.Removal of protein precipitates and dissolution assay
2.Beverage food testing analysis and biofuel analysis
3.Sample preparation
4.Environmental monitoring and analysis
5.Analysis of pharmaceutical and original liquid products
6.Liquid chromatography sample preparation and specific QC Analysis
7.Air filtration and fluid detection

The Selection Of Chromatographic Filter Paper

Chromatographic filter paper can be divided into three types: fast, medium and slow. It is based on its different texture, the thickness and the speed of solvent unfolding on the filter paper.

When selecting the filter paper, people should combine the Rf value of the separated object. For the compounds with slight differences in Rf values, slow filter paper can be used to separate the compounds clearly because using the fast filter paper will cause the inseparable weight of the separation zone. For the compounds with large differences in Rf value, medium or fast filter paper is suitable.

As to the thickness of filter paper, it should be determined according to the purpose of separation analysis. The thin chromatography filter paper is used for general qualitative analysis, and the thick chromatography filter paper is used for quantitative analysis or preparation.

When the chromatographic filter paper is applied to the experiments, it should be treated by different methods, such as immersed in a non-polar solvent, insoluble inorganic, or salt solution or non-volatile solvent and so on. In a way like this, the filter paper can be buffered separately for reverse phase chromatography and separation.

Comparison Of Bottle-Top Dispenser And Pipettes

World-known brands of bottle-top dispenser and pipettes

If you are in the separation industry, you must know the following brands, EPPENDORF, GILSON, Finnpipette, and Thermo Fisher and the like. Also, the BIOHIT, BRAND, NICHIRYO and RAININ, SOCOREX, Hamilton, Hawach, Labnet, and the CAPP also enjoy wide popularity.

Comparison
Usage
A pipette is a device that removes a small amount of liquid. The bottle-top dispenser is a device for installing a large amount of solution at the mouth of a solvent bottle.

Classification
The Hawach bottle-top dispenser and pipettes can be divided into the manual type and electric type. The manual pipettes are commonly seen with three different series: standard, advanced and advanced plus. The first two are half of the sterilization and the advanced plus series is all sterilization.

The manual bottle-top dispenser can separate the liquid volume from 0.5ml to 50ml and the electric mode can manage the volume from 0.1ml to 99.9ml.

Property And Different Performance Of Syringe Filter

Syringe filter offered by Hawach Scientific provides with a fair and competitive price, it uses the latest manufacturing technology to ensure a high quality and maximum sample recovery. Besides, it is noted for its originality and exquisite appearance.

Compared with other syringe filters, it provides a longer sampling range and higher protein recovery. In addition, it features in better chemical compatibility, and greater pressure resistance.

Different Performance of Syringe Filter

Advanced syringe filter is characterized in clear color and ultrasonic welding, and it is easy identification with the printed description of filter pore size and filter material; disposable syringe filter is designed with color code, and it adopts standard female Luer lock and male roller accessories, and it had lower cost and price; sterile syringe filter are constructed with virgin polypropylene and produced from pigment-free polypropylene or polycarbonate.

Compared with disposable syringe filter, sterile syringe filter has wide selection of pore size, larger hold-up volume. In aspects of maximum operating pressure, disposable syringe filter is 6.2bar, advanced syringe filter and sterile syringe filter are both 5.2bar. Housing are all adopted PP materials.
