Production Technique And Matched Application Of Glass Solvent Filter

Why We Choose Vacuum Filtration?

Vacuum filtration is highly appreciated by scientists as the ideal technique. Suction is applied to a mixture of liquid and solid to get the fast and efficient results when we need to separate and keep the precipitate safe from a solution.

On the one hand, vacuum filtration has lots of advantages. Gravity filtration uses the force of gravity to pull a solvent through a filter and leave the insoluble solids behind. Vacuum filtration is set up with a Buchner funnel set into a flask with a sidearm to be connected to a vacuum, and the filter paper is placed over the base of a Buchner funnel. Vacuum from Hawach diaphragm vacuum pumps can be applied to pull the liquid through the paper. Due to the force of vacuum, vacuum filtration is faster and more efficient at removing residual liquid and give out a purer solid than gravity filtration.

On the other hand, vacuum filtration sometimes carries more risk of losing some of the solids if you can not handle it with care. And it should be used only to collect insoluble solids because the vacuum will increase the loss of the low boiling solvent from boiling off.

Hawach vacuum filtration products are always recommended for well-prepared laboratories and for the scientists who want more accurate and efficient results.

Methods of Matched Application
The product is best used with a filter bottle and an air pump. There is a thin glass nozzle on the side of the filter bottle, and the glass nozzle is connected to the pump with a hard snake skin tube. Find a rubber plug of the right size, punch a slightly tighter hole in the middle, put it on the big hole above the filter bottle, plug it up, plug the sand core filter into the hole of the rubber plug, start the pumping pump, and use the negative pressure to filter quickly.

Benefits of Matched Application
In chromatographic analysis, the use of suitable equipment can not only effectively prolong the service life of glass solvent filter, but also obviously improve the data accuracy of the analysis system because of its vacuum degassing effect. In addition, this device selects high quality and high strength ultra-hard glass material, and is equipped with aluminum alloy special clamping for the whole device to connect, seal, and after oxidation treatment, it can resist chemical corrosion.

Material Selection
Hawach glass solvent filter is mainly applied to the flow phase filtration, particle material analysis and microbial contamination detection of the safe liquid chromatography. It uses high-quality、high-strength and ultra-hard glass materials, range temperature is up to 270 degrees, and has good pressure resistance, specifications are 2 liters and 1 liter. It can be used in conjunction with the oil-free vacuum produced by our company. Moreover, the high-quality borate glass is used as the material, and various water solutions, organic matters and corrosive liquid can be filtered in the analysis.

Instrument Characteristic
1.Classical design, easy to use.
2.The filter bottle is mass-produced. It is not only beautiful in appearance, uniform in wall thickness, but also has good interchangeability.
3.The oil-free vacuum pump which is matched with the filter bottle device is small and practical, the operation is simple and convenient, the efficiency is high, and the noise is low.
4.The solvent is directly extracted, so that the filtering process can be kept fully sealed as far as possible, the pollution can be reduced, and the degassing effect can be enhanced.
