Nano phase-change constant-temperature culture dish and manufacturing method thereof

Abstract

The invention provides a nano phase-change constant-temperature culture dish which is characterized in that a single-layer structure of a traditional culture dish is improved, a double-layer culture dish in a hollow sandwich structure form is manufactured, a nano phase-change constant-temperature capsule material is injected into the middle of a sandwich layer, and the nano phase-change constant-temperature culture dish is manufactured after the sandwich layer is sealed. According to the culture dish, when the environment temperature rises, the nano phase-change capsule material can absorb andstore external heat, and when the environment temperature is lower than the phase-change temperature, the nano phase-change capsule material can release heat outwards, so that the temperature in theculture dish is kept relatively stable within a certain time range. The invention also provides a manufacturing method of the nano phase-change constant-temperature culture dish.

Description

technical field [0001] The invention relates to the technical field of production, manufacture and application of microbial culture vessels, in particular to a nano phase-change constant temperature culture vessel and a manufacturing method thereof. Background technique [0002] At present, the commonly used microbial petri dishes in the biological test culture room generally adopt the traditional upper covered glass petri dish or plastic petri dish. Growth is easily affected by changes in the external environment, especially in the case of a power outage in winter that cannot continuously heat the incubator and the cultivation room or lose the constant temperature protection conditions in a short period of time, such as the transfer of the site, which may affect the microorganisms or biological cells that require constant temperature cultivation. Causing irreparable accidental losses is a practical problem that can generally be encountered in the microbiological culture dep...

[0002] At present, the commonly used microbial petri dishes in the biological test culture room generally adopt the traditional upper covered glass petri dish or plastic petri dish. Growth is easily affected by changes in the external environment, especially in the case of a power outage in winter that cannot continuously heat the incubator and the cultivation room or lose the constant temperature protection conditions in a short period of time, such as the transfer of the site, which may affect the microorganisms or biological cells that require constant temperature cultivation. Causing irreparable accidental loss is a practical problem commonly encountered in the microbiological culture department and needs to be solved
