Sample fine filtration purification device filter

Sample fine filtration purification device filter

Sample fine filtration purification device filterstructure：

1.There is a cylindrical graduated funnel

2. Sand core filter

3. Special card clip, composed of three parts

filterSuitable for filter membranes with a diameter of 47mm

Purpose:

Suitable for chemical analysis, hygiene inspection, environmental monitoring, biological products, pharmaceutical industry, scientific research, etc., used to filter out particles and bacteria. For example, oilfield water injection, analysis of suspended solids concentration, membrane filtration coefficient, particle diameter and sterility test, cultivation and sterilization filtration. Sterilization and filtration of thermosensitive drugs to achieve sterility, as well as analysis and determination of aviation kerosene, hydraulic oil, high-purity reagents, and water quality.

Usage：

1. Place the filter membrane in the center of the sand core board;

2. Use a cylindrical graduated funnel to press down on the filter membrane;

3. Specially designed clips clamp the upper and lower flange edges;

4. Wash oil and salt with organic solution and distilled water or filter other solutions, visually filter the speed with a hand pump or vacuum pump.

characteristic:

1. This product is designed and produced using SH/T0093 technology, and has been approved by the Shanghai Technical Supervision Bureau, China National Petroleum Corporation Equipment Company, and Shengli Oilfield Geological Department

The college and other units strongly support and cooperate in conducting relevant project tests, and the results are good.

2. Made of high-quality silicate material, it can withstand hot pressing disinfection, and the flange mouth is finely polished with good sealing performance.

3. Use standard plug connections for easy interchangeability and operation.

matters needing attention:

1. It is not suitable for filtering hydrofluoric acid, hot concentrated phosphoric acid, hot or cold concentrated alkaline solutions to avoid corrosion of silicate materials or damage to sand cores.

2. When using, both the upper and lower flange ports should be placed flat and secure before being clamped tightly with a special clip to prevent damage or leakage.

3. Filter membrane paper can be purchased or purchased by users according to different characteristics.

If any components are damaged, they can be replaced at the local glassware store or provided directly to our company.

Social and economic benefits:

A solvent filter is a glass instrument used for analysis and testing. Due to its connection with a vacuum pump, it has a filtration rate that is 20-30 times faster than foreign hand pumps, saving time and improving work efficiency. *.
