About the Features, Applications, and Cleaning of Glass Solvent Filter

The glass solvent filters adopt glass material, with uniform wall thickness, no bubbles, beautiful appearance, which can be used for sterilization under high temperatures and high pressure. It has good sealing performance, fast flow, and a standard grinding mouth. It’s made of borate glass, which can filter various aqueous solutions, organics, and corrosive liquids in the analysis, and can be autoclaved at 121°C.

The solvent filter is divided into three parts: the upper, middle, and lower parts. The upper end is a cup-shaped grinding container, named filter cup, with a capacity of 300ml and 500ml, so Hawach has 300ml glass solvent filters and 500ml glass solvent filters for your choice. It is used to support the filter membrane, and the corresponding specifications are 1L and 2L; the lower end is a pressure-resistant container with an external grinding mouth, called a triangular flask; the corresponding capacity is 1L and 2L, and it is equipped with special aluminum alloy clamps. For the tight connection of the entire device, the clamp is oxidized to resist chemical corrosion.

The glass solvent filter is a standing device in the chemical laboratory and is indispensable special equipment for liquid chromatography analysis. In the chromatographic analysis, impurities that affect the accuracy of the system can be removed, the service life of the column is extended, and the chromatographic and chromatograph are important. It is widely used in laboratory chromatography. The degassing effect of the glass solvent filter on the liquid during the filtration process is also significant. According to the test requirements, solvent filtration uses different types of membranes and is equipped with an oil-free diaphragm vacuum pump to remove impurities, clarify filtration, improve filtration efficiency and analytical precision, and enhance the effect of degassing. The glass solvent filter unit is equipped with a microporous membrane for liquid analysis in chemical analysis, instrumental analysis, sanitation inspection, the pharmaceutical industry, biological products and pesticides, petroleum, environmental monitoring, etc. to monitor and remove particles and bacteria from liquids.

Main features of glass solvent filter

We can select different materials and filter membranes with different filter apertures according to the needs of the operator to achieve the functions of removing impurities in the solvent, purifying, and sterilizing. In chromatographic analysis, the solvent filtered by it can not only effectively extend the service life of the chromatographic column, but also significantly improve the data accuracy of the analysis system due to its vacuum degassing effect. Made of extra-hard glass and featuring uniform wall thickness, good interchangeability, high pressure resistance, and high acid and alkali resistance, the glass solvent filter is frequently used in many industries.

Applications of Solvent filter

The glass solvent filters are standing equipment in chemical laboratories. The device is lined with a microporous filter membrane, which can be used for chemical analysis, sanitary inspection, biopharmaceutical and pesticide, petroleum, environmental protection, and other aspects of sample filtration.

The solvent filter is mainly used for rapid filtration of liquid chromatography HPLC mobile phase; it has a certain degassing effect to prevent and prevent the blockage of HPLC liquid path; it can filter various aqueous solutions, organic matter, and corrosive liquid particles. The solvent filtered by the solvent filter can prolong the service life of the instrument and the chromatographic column and improve the detection accuracy. Meanwhile, we often use it in many other industries, such as colloidal separation, microanalysis, gravimetric analysis, sterile experiments, and so on.

Glass solvent filter is mainly used for the filtration of water, organic and corrosive liquids. It is used for the analysis of specific pollutants. It is especially recommended for the filtration of the HPLC mobile phase. It has a certain degassing effect to ensure the mobile phase. Clean and prevent blockage of the HPLC liquid path. Can also be used for sterility testing, culture sterilization filtration, and sterilization of allergens.

Solvent filter cleaning method

After using it for a period of time, the titanium rod filter element of the solvent filter will become clogged to a certain extent, showing that the flow rate is reduced, and the pressure at the front end of the filter increases, such as: from below 0.22mPa to above 0.3mPa, then the filter element must be cleaned. There are generally the following cleaning methods:

1. For newly used filter elements, clean water backflushing and gas backflushing are generally used for cleaning, that is, flushing with clean water slightly greater than the working pressure (eg, 0.3mPa) in the opposite direction for cleaning.
2. For multiple backwashing, when the filtering effect does not rise significantly, use the hydrochloric acid solution below 5%, sulfuric acid solution below 8%, or NaOH solution below 10% soak at room temperature, and then rinse with water.
