Main products of Hawach

Its main business covers bottle-top dispensers, pipettes, QuEChERS-related products, flash columns, HPLC columns, SPE cartridges, syringe filters, filter cartridges (including, filter bags, filter capsules, filter housing), membrane filters, extraction thimbles, filter paper, vacuum filtration. HAWACH products are the ones used in the QuEChERS method, including the extraction box (salt bag and 50ml centrifuge tube) and the purification box. SPE cartridge is usually used in laboratory small sample pretreatment, with 1ml, 3ml, 6ml, and 12ml at choice.

1. Extraction thimble
HAWACH mainly produces glass fiber extraction thimble and cellulose extraction thimbles, used in general Soxhlet extraction and glass fiber extraction thimbles, used when cellulose cartridges cannot be tried, like with a temperature higher than 120℃, strong acids, etc.

Generally, in a glass container below, it places the substance to be extracted, and the solution is repeatedly immersed to extract the required components from the substance (such as extracting pesticide residues from pepper). This experimental process is called Soxhlet extract. The extraction thimble also plays an important role in collecting particulate matter such as haze in the atmosphere. It is used with the haze collection device.

2. HPLC columns
In HPLC analysis, the chromatographic column packing has a small particle size and is easily clogged with foreign particles, so samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. The ion chromatography commonly used in environmental analysis also requires that no inorganic pollutants be introduced into the sample pretreatment. We usually use it in HPLC analysis and IC analysis.

3. Syringe filter

Filtering the sample solution is an important step in the sample pretreatment process. The filter is available in the material of Nylon, MCE, CA, CN, PES, PVDF, PTFE, PP, and Glass Fiber, with pore sizes ranging from 0.1μm to 10μm, which had been widely used in such industries as pharmacy, chemistry, bioscience, microelectronics, food & beverage, etc. HAWACH syringe filter features high cleanliness, easy operation, and high precision, with various specifications. Filter housing material uses sanitary polypropylene material. The precise design guarantees smooth filtering rationalized internal space, and a very low residual rate, which is only half that of other products on the market, thereby reducing the waste of samples. Such as Disposable Nylon Syringe Filter.

4. Vacuum filtration
HAWACH vacuum filtration device can replace the standard diaphragm vacuum pump and anti-corrosion vacuum pump. It requires no special working medium, without friction in the working part. The vacuum index can be adjusted according to experimental requirements. All parts in contact with the gas are made of rubber material, which has a strong resistance to chemical corrosion. The valve disc is made of high-quality materials, with branded motors. The transmission mechanism has a reasonable design, reliable operation, small size, lightweight, convenient movement, and space-saving.

5. QuEChERS products
HAWACH products are the things used in the QuEChERS method, including extraction boxes and purification boxes. The extraction box includes a salt pack and a 50ml centrifuge tube. The purification box is filled with the adsorbent directly in a 2ml, 15ml centrifuge tube. Another type of product is a set, that is, an extraction box + a purification box, by which the customer can do the whole set of experiments.

6. Filter paper
The choice of filter paper is determined according to the requirements of the analytical work for filtering the precipitate and the nature and amount of the precipitate. HAWACH filter paper filters out impurities in the liquid via ultrafine fibers to achieve the purity we need. Its uniform fiber distribution, large dust-holding capacity, small resistance, and high strength make it an ideal filter material. Welcome to contact HAWACH for the filter paper’s type, specification, and scope. Such as 25 Micron Quantitative Filter Paper: BIO-41.

7. Pipette
A variety of pipette tips are available, and the application range of different pipette tips will be slightly different. HAWACH will provide you with a full range of solutions for pipette tips. All accessories are made of high-quality materials because we consider accessories to be an important part of the pipetting system. When not in use, the pipette should be hung vertically on the stand to prevent liquid from flowing back into the pipette, damaging the piston, or causing pollution.

8. Bottle-top dispenser
HAWACH integrates the latest accurate liquid distribution technology, high-tech materials, and ergonomically designed dispensers to make it an easy, safe, reliable, and highly accurate laboratory device. All liquid contact parts are highly chemically resistant and it is suitable for any laboratory bottle. For large-capacity dispensers, also has a micro-adjustment ring, which can ensure high accuracy when dispensing large volumes.

9. Filter cartridge(filter bag, filter capsule, filter housing)
Filter bag: Deep filtration, particularly large filtration flow, low resistance, long service life, low cost, no fiber shedding, easy operation. Filter bag material: There are four materials to choose from: PET, PP, PP, PP, and NMO; there are two kinds of interface materials: stainless steel ring, and PP plastic ring. It is available in 5 sizes.

Filter capsule: The outer shell is made of high-temperature polypropylene material, and the inner filter element is made by welding the folded filter element together. It does not contain adhesives and other chemicals. For filtering 1-20L laboratory and other small-dose liquids, gases, or industrial precious small-volume liquids.

Filter housing: High filtration accuracy and fast speed; less adsorption, no medium shedding, no dead angle, no leakage; acid and alkali resistance, corrosion resistance, easy cleaning, and can be recoiled.

10. SPE, FLASH, HPLC column
HAWACH offers you SPE columns with a variety of packing media, including graphitized carbon, alumina, silica gel, florist, HLB, C18, WAX, WCX, etc., which can be used to concentrate or separate complex sample matrices of different targets. Choose different adsorbents and solvents based on the polarity (polar, non-polar) or charge (anion, cation) of the analyte.

HAWACH provides you with Flash columns with a variety of packing media, including aluminum oxide, C4, C8, NH2, CN, HILIC, etc., which can be used economically, quickly, and in batches for biochemical samples such as direct HPLC analysis of fermentation broths, food and beverages, Chinese herbal extracts, blood samples, and complex samples.

There are two main series of HAWACH HPLC columns: Xchroma Series has more columns choice than the Echroma series, but the Echroma series are more cost-effective. They are featuring high column efficiency, large peak capacity, excellent batch stability, high-quality chromatographic packing, high purity, and good uniformity.
