Features of Hawach Syringe Filter

With the feature of low adsorption of samples and maximum recovery of small or high-value samples, the syringe filter is used for small amount of samples filtration in the laboratory. The lower part and upper part of the syringe filter are welded together by ultrasonic with the housing of polycarbonate, polypropylene, polyethylene plastic, featuring high pressure resistance and no leakage problems. Therefore, it will not contaminate the sample.

Relatively speaking, PES, MCE, PTFE, NY, PVDF, etc. Mainly trap particulate matter in the membrane. The GF membrane surface has strong dirt holding capacity, but for the absolute retention accuracy, it is lower than the microporous membrane.

Therefore, it is often used in coarse filtration and pre-filtration to give priority to the retention of large particles, while protecting the efficiency of the subsequent membranes, preventing the subsequent membranes from being blocked, and increasing the product use effect. Another membrane that can be used as a pre-filtration is PP, which is the same as GF and used at the front end of membrane filtration to prevent filter clogging.

There is no problem with the stability of syringe filter. The reason is: for the factory's strict quality control, there are strict links such as raw material inspection, production process monitoring, and finished product inspection to ensure that its quality is correct. For most laboratory needs, HAWACH syringe filters are suitable.

HAWACH syringe filter features

1. It is suitable for the filtration of a small amount of samples in the laboratory, and the adsorption of the samples is extremely low, which ensures the recovery of the samples.
2. The outer shell is made of polypropylene material without adhesives and will not contaminate the sample.
3. The outlet of the tube can be connected to facilitate the accurate filling of the filtrate into the micro bottle.
4. Equipped with membranes of different materials, which can be selected according to the nature of samples. For ventilation and sterilization, the PTFE hydrophobic, PVDF, activated carbon series are chosen. For organic solution, Nylon, PTFE hydrophobic, PP membranes will be used. For organic water mixed solution, Nylon, PTFE hydrophilic, PP are used. For water system, most hydrophilic membranes can be used. Commonly used membranes in biology are PES, MCE, CA.

In general experiments, it is used to filter samples, mobile phases, solvents, etc. Therefore, if certain impurities are dissolved in the filter membrane itself during the filtration process, it will seriously affect the customer's experimental results. HAWACH membranes have the following advantages in this regard:

1. The membrane is made of high quality raw materials with uniform material and low impurity content;
2. 10W clean workshop cutting and packaging, high cleanliness, no impurity introduction.
