Description

Technical Field

[0001] The utility model relates to the technical field of mixer auxiliary devices, in particular to a multi-hole mixer adapter capable of being sealed in batches. Background Art

[0002] Testing work carried out in the fields of biochemistry, medicine, etc. often requires the simultaneous processing of a large number of samples, including multi-step liquid preparation, sample addition, mixing, heating and other operations. In order to ensure the accuracy of the test results, it is necessary to use various methods to achieve synchronization of operations between samples as much as possible to avoid a large gap in the reaction time of samples processed before and after due to long operation time.

[0003] Mixers are small devices commonly used in testing laboratories. They can mix various experimental sample tubes, including vortex mixers, rotary mixers, reciprocating mixers, etc. The structure generally includes a host and replaceable adapters of various specifications. There are multi-hole, single-hole, flat plate and other forms, which can be used in different experimental scenarios. Among them, the multi-hole adapter can insert multiple or even dozens of sample tubes at the same time and mix them at the same time, which greatly improves the work efficiency and synchronization between samples, and ensures the validity of the test results.

[0004] In experimental scenarios that require batch mixing, a multi-hole mixer is often used to mix the sample tubes. However, the sample tubes often require other operations before and after the mixing step. For example, when disposable glass ampoule tubes are used as sample tubes, the bottle mouth generally needs to be sealed before mixing to prevent liquid splashing during the mixing process. After mixing, the next step often requires heating the sample in a water bath, or repeatedly performing mixing and heating operations. There are generally two ways to perform such operations. One is to manually perform sealing, transfer and other operations one by one, but this will take a lot of time and cause asynchrony between sample tubes. The second is to use fully automatic equipment. Although it is very efficient, the equipment is expensive and not suitable for use in non-professional testing laboratories. Utility Model Content
