A quantitative constant temperature agar pourer

Abstract

The invention relates to a quantitative constant-temperature agar pouring device. The quantitative constant-temperature agar pouring device is mainly applied to a biological or medical experiment. The quantitative constant-temperature agar pouring device comprises a liquid discharging switch, a quantifying valve, a plunger, a one-way valve, a sample feeding port, a bottle cover, an insulating layer, a storage bottle, a plunger cavity, a return spring, an inlet pipe, a fixing groove, a partition board, electric heating plates, a charging interface, a storage battery, a storage battery switch, a control circuit, a temperature sensor, a temperature display, a control cabinet, a sample feeding table, a constant-temperature water bath, a vent hole and an outlet pipe. The storage bottle with agar is put into the small charged constant-temperature water bath for thermal insulation, and during operation, the quantitative constant-temperature agar pouring device can be placed on a sterile working platform, and through adjustment of the quantifying valve below the liquid discharging switch, the agar pouring volume is controlled to quantitatively pour the constant-temperature agar so as to meet requirements of a pouring culture method, bacterium-containing agar plate preparation and other experiments on sterile operation as well as precise control over the agar pouring volume and the temperature. The quantitative constant-temperature agar pouring device is convenient to move, easy and safe to operate and low in cost, and has relatively high popularization and application values and very strong creativity.

Description

technical field [0001] The invention relates to the technical field of biological or medical experiment equipment, in particular to a quantitative constant temperature agar pourer. Background technique [0002] Many experiments in biology and medicine need to pour 45°C constant temperature sterile agar into the petri dish containing the sample solution containing bacteria and mix well, or mix the bacterial suspension with 45°C constant temperature sterile agar first and then pour it into the culture dish in the dish. If the temperature of the agar is too high, the bacteria will be scalded to death, and if the temperature is too low, the bacteria will solidify. Usually, the agar needs to be kept at a constant temperature of 45°C. In addition, in order to ensure the repeatability of the experiment, the agar needs to be poured quantitatively, and the agar pouring needs to be completed in a sterile environment (such as an ultra-clean workbench). Therefore, the stability of the...

Problems solved by technology

[0004] In the process of pouring the agar into the petri dish, the existing method is usually to pour the agar in the Erlenmeyer flask into the petri dish according to experience, which is difficult to ensure that the same amount of agar is poured into the petri dish each time

If you use a pipette or a pipette to draw quantitatively and then pour the agar, the operation will be time-consuming and laborious, and it is easy to solidify due to the cooling of the agar during the operation.
