Description

Culture dish transportation and containing device

Technical Field

The utility model relates to a culture dish field especially relates to culture dish transportation holding device.

Background

The field of microbial detection often involves field sampling work of related detection items, such as air microbial detection in public places, microbial detection in centralized air conditioning ventilation systems in public places, detection of planktonic bacteria, sedimentary bacteria and surface microorganisms in clean rooms (areas) in the pharmaceutical industry, and the like. For the microorganism detection project which needs to be sampled on site, the guarantee of the sterility of the microorganism culture dish is extremely critical, and the transportation process of the microorganism culture dish from a laboratory to a detection site is an important link which has great threat to the sterility of the culture dish, so the sterile transportation process of the microorganism culture dish is particularly important and critical for the site sampling work of the whole microorganism detection project.

At present, a traditional microorganism culture dish accommodating container is generally a covered stainless steel barrel with a simple bracket inside; prior to loading into the microorganism culture dish, it is typically autoclaved to ensure sterility of the interior thereof. At present, due to the simple structure and the rough design of the stainless steel barrel accommodating container, the sterility of the microorganism culture dish in the transportation process is still difficult to ensure even if the stainless steel barrel accommodating container is sterilized by high-pressure steam before use. The containing container has simple structure and rough design, and can keep the culture dishes pressed and not loosened with each other only under the condition that the culture dishes are 100 percent full, while the situation that the culture dishes just can 100 percent fully fill the whole stainless steel barrel containing container in the actual detection work is few; under the condition that the culture dish is not full in most of the time, the culture dish shells are broken due to mutual impact, scattering of the culture dish cover, falling of a culture medium in the culture dish and the like due to reasons of bumping and shaking in the transportation process. The sterility of the microbial culture dish in the transportation process is difficult to guarantee under the above conditions, and even the individual integrity of the whole microbial culture dish is difficult to guarantee. This patent will provide a culture dish transportation holding device for microorganism witnessed inspections that can solve above-mentioned problem.
