The bacteria collection instrument and the microbial limit instrument are not the same thing, and there are some similarities and differences between the two. The specific editor will explain it in detail to everyone.
The common points between the bacteria collection instrument and the microbial limit instrument are:
1. The bacteria collection instrument and microbial limit detector are mainly used for adsorption and inspection of microorganisms, bacteria, and the like
2. Both use membrane filtration method
The difference between the bacterial concentration analyzer and the microbial limit analyzer is as follows
1. The bacteria collector is used for sterility testing, while the microbial limit detector is used for bacterial testing. If a reusable incubator is placed on the bacterial collector, it can be used to determine the microbial limit of purified water.
2. The bacterial collection device is a supporting instrument for the bacterial culture device. Through the directional peristaltic pressure effect of the bacterial collection device, the test sample is filtered and cultured in the filter to test whether the test sample contains bacteria. The function of the bacterial collection device is to test whether the test sample contains bacteria, and it is used in conjunction with a bacterial collection culture device. Mainly used for sterile testing of sterile preparations for injection, including antibiotics and drugs containing antibacterial agents, large infusion fluids, water injections, sterile medical equipment, sterile injection water, etc.
The microbial limit detector is generally made of stainless steel metal material, equipped with an internal or external diaphragm pump. The test sample is injected into the microbial limit incubator, and filtered through the negative pressure of the diaphragm pump of the tester. The microorganisms in the test sample are intercepted on the filter membrane, and the filter membrane is removed using a membrane extractor and transferred to a prepared solid culture medium, with the bacteria facing upwards and flat. Close the lid to form a closed incubator, place it in the corresponding constant temperature incubator for cultivation and counting.
Both are membrane filtration methods, and the sterile results of the bacterial collection device require sterility. If there is a microbial limit, there can be bacteria. If the bacterial collection device is placed on a reusable incubator, it can be used to determine the microbial limit of purified water. The microbial limit detector is used for microbial limit detection, which is a sealed filter membrane filtration device. The filter membrane is then taken and cultured on a flat culture medium. The bacterial collector also has a sealed filter membrane filtration device. After filtration, the culture medium can be directly poured onto the back of the filter membrane, and then it can be cultured directly!
The microbial limit detection device is made of stainless steel metal material. The test sample is injected into a microbial limit incubator, and filtered by the vacuum pump of the tester. The microorganisms in the test sample are trapped on the filter membrane. The filter membrane is removed using a membrane extractor and transferred to a prepared solid culture medium. The bacteria face up and are flat attached. The lid is closed to form a closed culture box, which is then cultured and counted in a corresponding constant temperature culture place
The above is the similarities and differences between the bacteria collection instrument and the microbial limit instrument. I hope it can help you. Many pharmaceutical and food factories use these two devices, mainly for the detection of microorganisms and bacteria, as well as the pre-treatment equipment for the next step of detecting specific bacteria.
