DW-28 series water microbial membrane filtration deviceNetwork version parameters

Product Introduction:

DW-28 series water microbial membrane filtration deviceIt is a new generation instrument for microbiological testing of water samples containing small amounts of microbial contamination. It follows the national standards "GB 5750.12-2006 Standard Test Methods for Drinking Water Microbial Indicators" and "GB/T 8538-2008 Test Methods for Drinking Natural Mineral Water" for microbiological testing in waterExperimental equipment.

This product is widely used for water microbial quality control in environmental monitoring, food and beverage industry, cosmetics and pharmaceutical industry.

Product advantages:

1. The all stainless steel material filtration system is more resistant to high temperature and high corrosion.

The DW-28 series water microbial membrane filtration device replaces the traditional "suction cup membrane filtration" single sample detection method, supporting single sample filtration as well as multiple sample filtration, which can save a lot of time when detecting a large number of samples.

Technical parameters of DW-28-3 type:

1. System material: The triple all stainless steel filtration system is made of "316 stainless steel containing molybdenum", which is more corrosion-resistant at high temperatures than using 304 stainless steel.

2. Sterilization method: Filters can be sterilized using 121 ℃ wet heat sterilization, 180 ℃ dry heat sterilization, or more efficient flame sterilization and other sterilization methods that comply with ISO8199 certification.

3. Filtration system: The filtration system consists of a stainless steel filter bracket and three filters. Both the bracket and the filters can be sterilized by flame and cooled quickly, allowing for quick reuse.

4. Flame sterilization: The all stainless steel system can adopt flame sterilization method, which can achieve rapid sterilization of the entire system in 1 minute, greatly improving the efficiency of microbial testing.

5. Direct discharge of waste liquid: using oil-free direct discharge vacuum pump; No waste liquid bottle is required, the filtered waste liquid can be directly discharged into the sewage tank or pool.

6. Filter design: large capacity (250ml or 500ml) design; The upper cover of the filter is equipped with ventilation holes, which can be installed with an air filter to avoid secondary pollution caused by microorganisms in the air introduced into the water sample; The inner wall of the filter has a capacity scale line, which facilitates precise sample addition.

7. Filter membrane support pad: The filter adopts stainless steel filter membrane support pad to ensure that the intercepted microorganisms are evenly distributed on the surface of the filter membrane,Support filtration operation with 47mm diameter filter membrane.

8. Filter bracket: 3-piece all stainless steel filter bracket, with independent switches for connecting to each filter, supporting simultaneous filtration of multiple samples or independent filtration of individual samples.

9. Supporting filter membrane: The system can provide Haige white membrane and white membraneBlack film enhances the recognition of microbial colonies after cultivation, providing sterilityAnalyze COA certificate.

10. Configuration: Triple water microbial membrane filtration bracketOne, one micro negative pressure vacuum pump, three 250ml stainless steel filters, one flame sterilization bracket, one flame sterilization gun, and 100 individually packaged sterile films.

Technical parameters of DW-28-6 type:

1. System material: The six piece all stainless steel filtration system adoptsMade of "316 stainless steel containing molybdenum", it is more corrosion-resistant at high temperatures than using 304 stainless steel.

2. Sterilization method: Filters can be sterilized using 121 ℃ wet heat sterilization, 180 ℃ dry heat sterilization, or more efficient flame sterilization and other sterilization methods that comply with ISO8199 certification.

3. Filtration system: The filtration system consists of a stainless steel filter bracket and 6 filters, both of which can be sterilized by flame and cooled quickly, making them suitable for quick reuse.

4. Flame sterilization: The all stainless steel system can adopt flame sterilization method, which can achieve rapid sterilization of the entire system in 1 minute, greatly improving the efficiency of microbial testing.

5. Direct discharge of waste liquid: using oil-free direct discharge vacuum pump; No waste liquid bottle is required, the filtered waste liquid can be directly discharged into the sewage tank or pool.
