Shanghai Guning Instrument's flapping aseptic homogenizer is mainly used for: food microbial analysis; homogenization of animal tissues, biological samples, cosmetics; meat, fish, vegetables, fruits, biscuits; microbiological analysis of drugs, etc., especially suitable for microbial detection Sample preparation. The working bin is made of high-quality stainless steel, which can effectively separate the samples of solid samples on the surface and internal microorganisms. The sterile homogeneous bag effectively isolates the samples from contact with the equipment. . Appropriate adjustment of working time and slap speed can achieve gentle homogenization of tissue cells.
Sterile homogenizer, also known as beating homogenizer, beating homogenizer. Mainly used for tissue dispersion in the field of biotechnology, sample preparation in the field of medicine, enzyme treatment in the food industry, and in the pharmaceutical industry, cosmetics industry, paint industry and petrochemical industry.
The working principle and precautions of Shanghai Guning instrument flapping homogenizer
The working principle of this instrument is: put the original sample (the large one needs to be cut into 10 × 10mm blocks), put it into a homogeneous bag with a certain liquid or solvent, and repeatedly hammer on the sample homogeneous bag through the hammer board of the instrument Impact, generate pressure, cause oscillation, accelerate mixing, so that the microbial components in the solution are in a uniform distribution state. This instrument is suitable for the homogenous treatment of brain, kidney, liver, spleen and other tissues and microorganisms. It is widely used in the fields of food, medicine, clinical, molecular, toxin and bacteria detection.
The device is equipped with a fully open glass transparent window door, which is easy to clean, and the glass transparent window is easy to observe. Using large-screen LCD display, the working time and homogenization speed are intelligently adjustable, and the beater can also adjust the front and rear distance at will. It can effectively separate the sample surface and the contained microbial uniform sample. The sample is isolated and operated with a disposable sterile homogeneous filter bag to ensure hygiene and safety, no contact with the instrument, no sample leakage and no system cleaning. It has the characteristics of convenient and fast, accurate results, homogeneous and soft, no pollution, no damage, no heating, no sterilization treatment, no need to wash utensils, and good repeatability requirements. This product is also suitable for the homogenization of tumor tissues (such as intestinal cancer, gastric cancer, liver cancer, breast cancer), which can obtain a large number of single cells. If necessary, the tissue cells can be broken softly by extending the homogenization time.
Treating these problems correctly can make the homogenizer serve you better.
1) The power plug must be firmly inserted into place. Looseness may affect the computer controller and cause a crash. If a crash occurs, turn off the power switch on the rear side, and restart after 3 minutes of shutdown.
2) Please do not open the homogenizer door at will when the hammer board is working to avoid overflow of sample liquid. It should be built according to "open / stop", and the equipment will automatically stop running. After closing the door, press "Open / Stop" to build, and the equipment will automatically complete the rest of the work. Do not reverse the operation.
3) If the instrument is not used for a long time, the power should be cut off and the plug removed. Prevent the aging of electronic components inside the sterile homogenizer.
4) The bottom of the homogenizer door is designed to prevent accidental rupture of the homogenization bag and facilitate the cleaning of spillage. The bottom is designed to be empty and can be used to place the water tray. It is best not to open the homogenizer door when the homogenizer is working, causing unnecessary losses.
5) Before running the machine, please check carefully whether there are foreign objects in the homogenization box, so as to avoid failure and damage to the homogenization bag during work.
6) Hard, sharp, hard and sharp materials, such as lumps, bones, and ice, should not be used to avoid damaging the homogeneous bag.
7) The storage of the instrument and the homogenous bag should avoid direct sunlight, especially the homogenous bag should be stored in a place without sunlight or ultraviolet radiation to avoid aging.
8) When the amount is small, the speed needs to be increased, and when the homogenous fiber is tough, you can use the rear knob to adjust the distance between the flapper and the window to achieve a better homogenization effect. Pay attention to the adjusted distance to avoid the occurrence of air strikes and other damage to the sterile homogenizer.
The correct steps for using a sterile homogenizer are:
1. Put the sample to be treated in a sterile homogeneous bag.
2. Open the homogenizer door (which can be fully opened) and clamp the opening of the sterile bag when closing the homogenizer door.
3. Set the use program (such as slap speed, slap time, etc.) to perform slap homogenization.
4. After the experiment, open the homogenizer door and take out the sample.
The use of a sterile homogenizer can greatly extend its service life and use effect if the above points are achieved.
