Detailed Description and Characteristics of 3-Branch Vacuum Filtration

Manifold vacuum filtration system is a kind of filtration product that can filter multiple groups of samples at the same time, and 3-branch and 6-branch are commonly used. That is, a single filtration operation can be completed at the same time to filter three or six groups of samples. This can significantly reduce the number of pumps and bottles purchased, reduce the space occupied by the table, and save the time of filtration operations, which helps to improve the efficiency of experiments.

Stainless Steel Three-Branches Vacuum Filtrations

3-Branch vacuum filtration introduction

3-Branch vacuum filtration is made of three filters in parallel, with many advantages such as novel and reasonable structure, good sealing, strong circulation capacity, easy operation, etc. It is a multi-purpose filtration equipment with wide range of application and strong adaptability. Especially, the chance of side leakage of filter bags is small, and the filtering accuracy can be accurately guaranteed, and the filter bags can be replaced quickly, and there is basically no material consumption for filtration, which makes the operation cost lower.

As a solution filtration device in laboratory, it is faster and can filter multiple samples at the same time with only one pump, which improves the efficiency of laboratory work. Secondly, it has independent control valves for each filter frame, so it can support single and multi-link operation at the same time. The material uses sanitary stainless steel, which is resistant to acid and alkali, corrosion and high temperature, and can withstand high temperature of 180℃, which is easy to sterilize at high temperature and makes the analysis results more stable; the production process is under the careful guidance and quality control of highly qualified technicians, which makes our products have superior quality assurance.

Applications

It is widely used in chemical analysis, biochemical and pharmaceutical, health testing, environmental testing, water quality analysis, food, beverage, scientific research, etc. It can detect three samples at the same time with high sensitivity and simple operation. Different materials of filter membranes can be selected according to the operator’s needs to filter different samples, such as suspended matter in samples, bacteria, chlorophyll, etc. It is suitable for colleges and universities, scientific research units, pharmaceutical plants, hospitals, etc. for culture medium, blood products, pharmaceutical solutions for sterilization or clarification and filtration.

Features

1. Quick connect design: the whole machine can be disassembled, including the filter head and filter tube, more convenient to clean and sterilize the internal residue. Quick connect filter head design, easy to replace the sterilized filter head when multi-sample filtration, to achieve rapid filtration of multiple samples. The silicone tube can be connected to the left and right, and the vacuum pump can be placed according to the specific laboratory conditions.
2. Special “three-claw” membrane clamping design, no additional clamps, easy to operate and remove the membrane with one hand, easy to operate and more efficient to use.
3. Modular design: The filter cups of this filter system are equipped with independent switches, which can filter single samples independently or multiple samples at the same time. Optional quick-connect vacuum gauge can be used to test the real vacuum level of the filtration process.
4. Stainless steel filter cup and glass filter cup two kinds of material can be chosen: according to different experimental conditions to choose different filter cup material.
5. High quality design: 316L sintered stainless steel filter membrane support pad is used to ensure that the filter membrane does not break or perforate during the filtration process, which guarantees the accuracy of sample detection and makes the microorganisms retained on the surface of the filter membrane uniformly distributed, facilitating the observation of experimental results.
6. Prevent secondary pollution: The filtration system is equipped with a ventilation hole in the upper cover of the stainless steel filter cup, and an optional air filter can be installed to avoid secondary pollution during filtration.
7. Improve detection efficiency: stainless steel filter sterilization method can be used 121 ℃ wet heat sterilization 15 minutes, 180 ℃ dry heat sterilization 120 minutes, or with high-temperature cauterization to achieve the purpose of sterilization. The inner wall of the filter cup has a clear volume scale line, which is convenient for quantitative sample addition.
8. Made of durable material: the main accessories such as filter, filter connector, valve, filter holder, filter top cover and filter membrane support pad are made of 316 stainless steel, which are not easily damaged and has long service life.
9. Different microporous filter membranes are available: hydrophilic membranes and organic membranes, each category has a wide range of pore sizes and dimensions, but the most used is still hydrophilic membranes, which is non-toxic and hygienic, a porous membrane filtration material with relatively uniform pore size distribution of penetrating micropores and microporosity of up to 80‰ pore size. The conventional sizes are 47mm and 50mm in diameter with 0.22μm or 0.45μm pore size.
