Embodiment Construction

[0013] A kind of device of demonstration fermentation experiment is that a glue tip dropper 2 inserted in the round hole of the rubber insert 3 is inserted into the glass test tube 1 with the head down, which can be made into the present invention. The rubber insert 3 can be replaced by a round hole rubber stopper of suitable size, and its diameter should be less than the inner diameter of the test tube 1, so as to be loaded or taken out. When in use, first take out the rubber tip dropper 2 together with the rubber insert 3, absorb a certain amount of microbial culture solution, insert it into the test tube 1, then fill the test tube 1 with clean water, and then put it into warm water with a suitable temperature to keep it warm, that is, Fermentation experiments can be demonstrated.

Abstract

The invention discloses a device for presenting a fermentation experiment, pertaining to a field of medical and laboratory equipment technology. The device comprises a plastic head dropper (2) which is interspersed inside a round hole of a rubber block (3). The plastic head dropper (2) is arranged inside a glass tube (1), wherein a rubber hose portion of the plastic head dropper (2) faces the bottom of the glass tube (1), and an opening portion of the dropper (2) faces an opening portion of the glass tube (1). The plastic head dropper which contains a microbial culture medium is embedded in the tube which contains clean water. Therefore the device of the invention only needs to be placed into warm water to maintain fermentation temperature. Gas generated in fermentation can emerge in the form of bubbles through the sharp mouth of the plastic head dropper, such that the experiment is very intuitive.

Description

technical field [0001] The invention relates to a device for demonstrating fermentation experiments, which belongs to the technical field of medical treatment and laboratory equipment. Background technique [0002] To carry out biology teaching, it is necessary to demonstrate the fermentation experiment of microorganisms. Known demonstration method is usually earlier to culture microorganism in Erlenmeyer flask, then check its fermentation product. Like this, it is inconvenient to keep the fermentation temperature, and the intuitiveness is also poor. Therefore, we invented a kind of rubber dropper filled with microbial culture solution embedded in the test tube. The test tube is filled with warm water to keep the fermentation temperature. Therefore, a device for demonstrating fermentation experiments of microorganisms visually is necessary. Contents of the invention [0003] The purpose of the present invention is to provide a device that can demonstrate fermentation ex...
