Description

Technical Field

[0001] The utility model relates to the technical field of biological applications, in particular to an adapter for maintaining a multi-well plate in a low temperature state for a long time. Background Art

[0002] Flow cytometry measures cells or particles in motion and can provide statistically significant single cell, particle or aggregate measurement data in a short period of time. At present, the development of flow cytometry technology has become an indispensable technology in many fields such as biological research, new drug research, and medical diagnosis. As these fields become more dependent on flow cytometry, higher requirements are also placed on high throughput and high accuracy of flow cytometry results.

[0003] However, high throughput and high accuracy require a trade-off in some cases. High throughput means a large number of samples and a long time required. In addition to technical requirements for equipment and personnel, high accuracy of test results usually requires that the test be completed immediately after staining. Using an automatic sample loader to automate sample loading can reduce the workload of personnel and shorten the sample loading time to a certain extent. However, when the number of samples reaches a certain level, even with an automatic sample loader, the entire detection process can take more than 2 hours. In some detection experiments on metabolites of living cells, the staining time is generally 30 minutes, and 2 hours of cell activity will have a significant impact on the test results. In cell biology, maintaining cells at a low temperature (such as 4°C or on ice) can significantly reduce cell metabolism and prolong the time that cells remain active.

[0004] The existing flow cytometer multi-well plate adapter can adapt to 96-well plates and automatically detect 96 samples at a time, which provides convenience for researchers to conduct high-throughput flow detection experiments. However, most of the adapters used are bottomless hollow aluminum alloy structures, which cannot maintain the low temperature state of cells in the multi-well plate for a long time by pre-freezing or putting in ice cubes.
