The microbial limit detection and filtration device is an instrument used by a general pharmaceutical factory, a food and beverage factory, a university research institution or a third-party testing institution, etc., for filtering the sample in the sample on the filter film, in the later stage. Cultivation, etc. There is no limit to the number of limit detection filter devices, and customers can select the appropriate model according to their own conditions.

According to the number of filtered samples: the microbial limit detection filter device can be divided into single, triple or hexa, the main difference is the number of samples that can be filtered at the same time. For users who purchase the instrument for the first time, if the initial workload cannot be accurately assessed at the beginning, you can choose to filter the three sets of samples of the BV-321-A triple vacuum filter device at the same time, and sample the aluminum material bracket to ensure the durability. This material can also be autoclaved. If the amount of sample filtration increases in the future, it can also pass through the three-way interface, so that only one vacuum pump can be used together with two sets of triple brackets, that is, six filter bowls can be used at the same time. At the same time, due to the valve switch, it is also possible to close the valve when not using a filter bowl.

According to the way of sterilization: the suction cup of the St. Stephens Sciencetool brand contains different materials, including 316 stainless steel, polyethersulfone plastic and glass. Customers who are accustomed to using Bunsen burner flame sterilization can use 316 stainless steel. If you have the filter funnel with polyethersulfone material, such as R300A vacuum suction filter, with 300ml polyethersulfone rotary card funnel and liquid collection bottle with bottom drain, customers can filter multiple sets of samples. With this device, it is only necessary to prepare a corresponding number of funnels before suction filtration, and to use them before use. Even if the filtrate volume is large, it can be quickly discharged through the bottom drain port, and it is not necessary to repeatedly dump the waste liquid bottle, which is simple and convenient.

According to the budget situation: If the customer has sufficient funds, you can choose the six-connected vacuum filter device with 316 stainless steel material with complete configuration and good material. Such as BV-630-B, this model is equipped with all the firmware and consumables required for the limit inspection filter, including suction pump, filter holder, filter bowl, flame torch for sterilization, microbial limit detection filter membrane, 3000mlPC material Liquid collection bottles and other accessories. If the customer is in budgetary considerations only for basic general filtration, the FS3310 vacuum suction filter can be selected, along with a suction pump, funnel, liquid collection bottle and other necessary accessories, but the filter bottle is made of all-glass material. , so the price advantage is obvious.
