How To Buy Different Classifications Of Vacuum Filtration System

The microbiological detection multi-linked vacuum filtration system is suitable for food and beverage production enterprises, pharmaceutical factories, disease control centers, medical treatment, university scientific research, or third-party testing institutions. It is suitable for the detection and filtration of the microbiological limit of the water to be tested. The principle is to install a filter membrane at a specific position in the filter device, pour the sample, and use the pressure difference generated by the vacuum pump to make the liquid pass through the filter membrane. After filtering, the filter membrane is placed in a Petri dish for cultivation.

The obvious difference from the general filtration is that the number of inspection samples is large. The use of traditional single-type filter bottles may result in lower filtration efficiency, and the use of professional microbiological detection multi-unit vacuum filtration system can filter out 3 groups at a time, 6 groups or more samples. At the same time, due to special use requirements, the requirements of microbiological testing for sterility and pollution avoidance are even higher.

Stainless Steel Six-Branches Vacuum Filtrations

There are many types of microbiological detection multi-vacuum filtration systems on the market. Customers can choose products that suit them according to these items when choosing:

The number of filtered samples: the common model classification is generally based on single, triple, and six. The main difference is the number of samples that the user can filter at a time, corresponding to 1, 3, and 6 groups, respectively. The unit needs to be filtered sample size to choose from.

At present, it is recommended that customers use the triple water microbial inspection vacuum filtration system. A vacuum suction pump is equipped with a set of triple filter brackets with three filter cups on the bracket, which can be filtered at the same time or can be closed using the valve switch lowered by the filter cup. No need for filter cups. And its big feature is that when the customer needs to increase the number of filtered samples in the future and need to expand the filter seat, only need to buy one more triple seat, through a straight connector can connect two triple seats in series, and still use only the original configuration a suction filter pump can realize the filtration work, no need to purchase additional suction filter pump.

Filter material: The filter material part can be divided into two parts, the main bracket material, and the funnel material. At present, the materials of the mainstream products are stainless steel and aluminum alloy. Both the aluminum alloy and the stainless steel can be sterilized at 121 degrees high temperature and high pressure, while the aluminum alloy has the advantages of lightweight.

The material of the stainless steel series vacuum filter body adopts cash anode aluminum alloy; funnel material types are more divided into stainless steel, glass, plastic, ceramic, etc., among which stainless steel material can be directly burned and sterilized by flame, the price of glass material is cheap, the structure of plastic material is simple and lightweight, and it is currently used. More and more widely.
