Description

Technical Field

[0001] The present application relates to the technical field of culture medium dispensing equipment, and in particular to a conveying device for automatic culture medium dispensing. Background Art

[0002] Culture medium is an artificially prepared nutrient matrix suitable for the growth and reproduction of different microorganisms or the accumulation of metabolites. It generally contains water, nitrogen source, inorganic salts (including trace elements), carbon source, growth factors (vitamins, amino acids, bases, antibiotics, pigments, hormones and serum, etc.). Culture medium filling equipment is a device used to batch fill culture medium. Through the culture medium filling equipment, a certain amount of culture medium can be filled into multiple culture dishes. After the culture medium is filled, the culture dish containing the culture medium needs to be transported by a conveying device.
