Description

Device for collecting samples

Technical Field

The utility model relates to a test device technical field specifically is a device for sample collection.

Background

In cell preparation, the whole operation process is performed in order to ensure sterility. Usually we will leave the sample to check after the whole operation is finished to determine if our operation is qualified. When in detection, a sample to be detected needs to be collected into a container, and whether the result is qualified or not is judged through aseptic detection.

The aseptic detection is to inject the sample to be detected into an aseptic detection bottle quantitatively by an injector, culture for a period of time and observe the growth curve to judge the detection result.

Currently, there is no specific device for collecting the sample to be tested. Typically we replace it with a 50ml centrifuge tube. The 50ml centrifuge tube is mainly used in centrifugation, and if the centrifuge tube is used for collecting a sample to be detected, the sample needs to be extracted by an injector and injected into a sterile detection bottle during detection, so that the operation is inconvenient. And because 50ml centrifuge tubes require a centrifuge tube rack to hold them in place. It takes up the operation space of the experiment. Causing inconvenience in the experiment.

In the detection, the sample to be detected is drawn by a 10ml syringe after the cover of the centrifugal tube is opened, and then is injected into a sterile detection bottle. In the process, the centrifugal tube is in an open state for a long time, so that the risk of contamination of the sample to be detected is increased. Thereby affecting the experimental results. And may cause sample leakage due to the open operation during syringe extraction. Also probably the syringe is when the sample that awaits measuring of extraction centrifuging tube bottom, can be because the hand of taking the syringe is too close apart from the mouth of pipe, and the centrifugal tube mouth is touched to the mistake, can cause bacterial contamination very probably, leads to the experimental result error to appear.

The above problems are now prevalent in the laboratory industry, and a device for sample collection is designed to solve the above problems.
