TST-ZP03B/06B series microbial limit filtration system


  TST-ZP03B/06B series of microbial limit filtration system based on the principle of membrane filtration method, and open filter (F250) and other components of a complete microbial filtration system. The microorganism is intercepted by the way of negative pressure suction filtration. Mainly used for all kinds of water quality, medicine, food and other media microorganism detection and laboratory sterilization, particle removal and so on. The operation process is not easy to be polluted and easy to clean.

  

  1. 

  

  2.   Method of use

  

  2.1. The assembly

  

  Connect the stainless steel base with the host machine and tighten it to achieve sealing effect. Take the silica gel tube, one end is connected with the main engine drain interface, the other end is connected with the waste liquid loading device. Thus, a complete microbial filtration system was assembled.

  

  2.2. Use

  

  Assemble the system on a clean workbench or other clean environment as required. Before use, check whether the connection between the stainless steel base and the host machine is loose. If it is loose, tighten it. Use the flame sterilizer gun to sterilize the stainless steel filter, open the choke valve, spread the filter membrane on the stainless steel base, buckle the filter cup, pour in the liquid to be filtered, start the power supply of the host, the sample in the filter cup will directly flow out along the fuselage drainage outlet, so that the microbes in the sample are separated from the sample, and the microbes are trapped on the filter membrane. After filtration, disassemble the filter and transfer the microporous membrane to culture under specific conditions.

  

  Carefully remove the filter membrane with sterile forceps and place the face (filter surface) flat on the surface of the medium. (Picture 2, Picture 3, Picture 4)

  

  

  2.3. Cleaning

  

  After filtration, the filter cup should be cleaned in time, soaked in water with neutral detergent, and then scrubbed with soft cloth

  

  (Do not use wire balls or other equipment that may scratch the plastic cup), rinse well and let dry naturally. If the filter medium contains positive control bacteria, the filter should be sterilized by wet heat before cleaning.

  

  2.4. Matters needing attention

  

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

  

  2. The maximum temperature applicable to the transparent cup body is not more than 130℃, otherwise it is easy to cause deformation and damage. After repeated autoclave sterilization and cleaning, the transparency may decrease. If it affects the experimental operation, it is recommended to replace the cup with a new body.

  

  3. Any mechanical impact (drop, collision) and improper use may cause damage to the product. It is recommended to operate with care and follow the instructions.

  

  5. The filter is not suitable for filtering the following media

  

  a)Strong acid;

  

  b)Strong alkali;

  

  c) Strong oxidant;

  

  d) Other kinds of organic solvents that are not compatible with the chemical properties of materials such as cups. (If in doubt, please contact us)

  

  6. If the filter is used for sterilizing test, special recovery catheter should be provided.

  

  7. It is strictly prohibited to sterilize the whole machine by high pressure steam.
