Stainless steel bacterial culture incubator (repeatedly used)

Stainless steel bacterial culture equipment is an accessory and consumable used for sterile inspection of bacterial collectors. Precautions: This consumable can be selected if no positive control is performed. The filter can be reused after sterilization and disinfection. The pump tube and filter membrane are disposable consumables, saving experimental costs

DESCRIPTION Product description

The stainless steel bacterial culture incubator adopts a stainless steel design and a transparent cup body design, which can be used repeatedly for a long time and reduce inspection costs; The operation process is not easily contaminated and easy to clean; Aseptic testing experiments such as sterilization and particle removal can also be conducted

Main features Principal character

Open the sterilization packaging and pump tube packaging in an ultra clean workbench/biosafety cabinet or other clean environment that meets the requirements. First, check whether the connection between the stainless steel base and the fixing ring on the filter cup is loose. If it is loose, tighten it. Assemble the pump tube, filter cup, and accessories into a complete fully enclosed filter using aseptic operation methods, and install the pump tube into the peristaltic pump of the bacterial collector for filtration. The aseptic experiment is consistent with the operation process of disposable incubators.

The entire process is based on the following principle:

Combination: Repeated use of incubator: Take a clean and dry incubator cup body, stainless steel base, and "O" - shaped sealing ring and other accessories. Place a 50mm diameter microporous filter membrane on the porous plate of the base (the material and pore size of the microporous filter membrane need to be determined according to the characteristics of the test sample and the test purpose). Insert the stainless steel fixing ring on the base from the top of the cup body and tighten it in place.

Disinfection: Use sterilization bags, gauze, and kraft paper to package the combined reusable incubator as required (at least 12 layers of gauze are required), place it in a moist heat sterilizer, sterilize it at 121 ℃ for 15 minutes, or use ETO method for sterilization. After disinfection, place it in a drying oven and dry it at ≤ 60 ℃ for later use. The shelf life depends on the packaging method and should comply with the operating standards for microbiological testing of drugs.

Usage: Open the sterilization packaging and pump tube packaging on the ultra clean workbench/biosafety cabinet in the sterile room, assemble the pump tube and accessories into a complete incubator using aseptic operation methods, and filter on the bacterial collector according to the prescribed method.

The operating method of the microbial limit test bacterial culture set is:

a) Hold the filter base firmly with one hand and loosen the fixing ring on the stainless steel base counterclockwise with the other hand. After rotating it into place, carefully detach the cup body.

b) Carefully remove the "O" - shaped sealing ring with sterile tweezers, and then remove the PTFE gasket.

c) Carefully remove the filter membrane with sterile tweezers and place its front side (filter surface) flat on the surface of the culture medium after filtration. After filtration, the microporous filter membrane needs to be disassembled and removed. At this time, the stainless steel base and fixing screw should be loosened in opposite directions with both hands, and the cup body should be carefully detached after loosening. Use sterile forceps to remove the filter membrane and place its front surface (bacterial surface) flat on the surface of the solid culture medium. After filtration or cultivation is completed, it should be cleaned in a timely manner. It can be boiled in soapy water and then cleaned with gauze (do not use steel wire balls or other equipment that may scratch the plastic cup), rinsed clean, and left to air dry naturally. If bacteria grow in the cup, it can be boiled in disinfectant or steam sterilized before cleaning. Disposable pump tubing should be fitted with a needle sleeve after each use, cut in the middle, and then disinfected.

Attention:

1. Before filtering the medium, check whether the fixing ring of the stainless steel base on the filter cup is loose. If it is loose, it needs to be tightened.

2. The accessories such as pump tubes, respirators, clamps, etc. are sterile packaged and provided by our company. They can only be used once and are not suitable for wet heat sterilization.

3. The maximum temperature suitable for transparent cup body is not more than 130 ℃, otherwise it may cause deformation and damage. After repeated high-temperature and high-pressure sterilization and cleaning, the transparency may decrease. If it affects the experimental operation, it is recommended to replace the cup with a new one.

4. Any mechanical impact (drop, collision) or improper use may cause damage to the product. It is recommended to handle with caution and follow the terms of this manual during use.

5. This filter is not suitable for filtering the following media: a) strong acids; b) Strong alkali; c) Strong oxidizing agent; d) Various organic solvents that are incompatible with the chemical properties of materials such as cup bodies.

6. Disposable pump tubing should be fitted with a needle sleeve after each use, cut in the middle, and then disinfected.
