Medium refers to a nutrient matrix prepared by the combination of different nutrients for the growth and reproduction of microorganisms, plants or animals (or tissues). Generally, it contains carbohydrates, nitrogenous substances, inorganic salts (including trace elements), vitamins and water. The medium is not only the basic material for providing cell nutrition and promoting cell proliferation, but also the living environment for cell growth and reproduction. There are many kinds of culture media, which can be divided into natural medium, synthetic medium and semi-synthetic medium according to the source of the prepared raw materials; according to the physical state, it can be divided into solid medium, liquid medium and semi-solid medium; The basal medium, the selection medium, the enrichment medium, the identification medium, and the like; may be classified into a bacterial culture medium, an actinomycete culture medium, a yeast culture medium, a fungal culture medium, and the like according to the use range. After the medium is formulated, it is generally required to test and adjust the pH. It must also be sterilized, usually by high temperature sterilization and filter sterilization. The medium is easily contaminated or deteriorated due to its rich nutrients. It should not be placed for a long time after being equipped. It is best to use it now. Chuangrui filling type Peristaltic Pump is mostly used for high precision dispensing of medium The medium is usually sterilized in a triangular flask or test tube.
(1) Triangle bottle
For static culture, 100ml medium / 250ml flask, up to 150ml medium / 250ml
Triangular bottle, otherwise the medium boiling during sterilizing will easily contaminate the tampon, causing bacteria; if it is shake flask culture, 15-20ml medium/250ml triangle bottle will ensure good ventilation.
The liquid medium is generally loaded with 4-5 ml, about 1/4 of the height of the test tube
Common media are: Beef Cream Agar Medium / Rhizobium Medium / Bovine Heart Medium / Actinomycete Medium / Flour Agar Medium / Microalgae Medium / SE Medium / Pr Medium / Fungal Medium / Edible fungus culture medium / tobacco culture medium / animal cell culture medium / selective medium Reasonable price, does not affect the accuracy of the dose
Easy maintenance, replaceable tubes allow you to switch from one product to another in the shortest amount of time.
Peristaltic pump with high precision
The suckback function prevents liquid (reverse): in the dispense mode, after the end of the direct cycle, the return stroke is initiated to prevent the liquid from flowing out of the pump tube during the stop.
Versatility
This peristaltic pump dispenser can be used with a variety of products and can be used in a variety of industries.
Easy to work
After the power is turned off and on, the control system maintains the current settings (pump head and hose, time and fill).
The principle of operation is based on the fact that the roller squeezes the liquid in the pump tube and the liquid moves along the roller, pushing the liquid forward. Only the hose (silicone tube) is in contact with the medium being transported, thus avoiding mutual contamination of the fluid and the pump.
Chuangrui peristaltic pumps are used in the pharmaceutical, food and chemical industries. The body is made of stainless steel AISI 304, which provides a corrosion-resistant casing and is easy to clean.
