Description

Technical Field

[0001] The utility model relates to the technical field of instrument flushing, in particular to a simple manual plate washer. Background Technique

[0002] The 96-well plate provides a multi-well platform for performing multiple PCR reactions simultaneously. Each well is an independent experimental unit and can be used to amplify different DNA samples or target sequences, greatly improving the experimental efficiency; in laboratory operations of methodologies such as ELISA and hybridization capture, there is an operation of washing the 96-well plate;

[0003] There are usually two cleaning methods in existing laboratories: one is to use a plate washer; the other is manual plate washing; however, both of these methods have significant drawbacks and pain points; plate washers need to be purchased, and it is generally impossible for small-scale laboratories to apply for a plate washer; when the sample volume is small, the speed of the plate washer is not as fast as that of manual plate washing. Therefore, even if there is a plate washer in the laboratory, manual plate washing will still be used when the sample volume is small or when rechecking samples during operation; manual plate washing generally uses a small plastic bottle and squeezes hard to wash by the pressure of water. When there are many samples, it is very laborious to wash, and when the sample volume is large, the washing efficiency will also be low, affecting the experimental progress. If the bottle is small, it is basically necessary to refill water after washing half of a plate with one bottle of water. If the bottle is large, it is difficult to apply force with the hand; for this reason, a simple manual plate washer is proposed. Content of the Utility Model
