Rapid vertical type plate cleaning machine for microporous reaction plates

Abstract

The invention discloses a rapid vertical type plate cleaning machine for microporous reaction plates. The rapid vertical type plate cleaning machine comprises a cleaning barrel. A centrifugal motor is arranged in the cleaning barrel. A centrifugal disc is mounted on an output shaft of the centrifugal motor. Multiple microporous plate trays are uniformly arranged on the outer side wall of the centrifugal disc, wherein the microporous plate trays are used for storing the microporous reaction plates. Holes are machined in the microporous plate trays. The sizes, the number and the distances of the holes are the same as those of holes in the microporous reaction plates to be cleaned. Cleaning needle assemblies are arranged on the upper portion of the side wall of the cleaning barrel. Each cleaning needle assembly comprises a cleaning needle mounting plate and cleaning needles fixed to the corresponding cleaning mounting plate. The number and the distancea of the cleaning needles are the same as those of the holes in the microporous plate trays. The rear portions of the cleaning needle mounting plates are connected with a pipeline and connected with a liquid pump and a gas storage tank correspondingly through a T joint. The liquid pump is connected with a cleaning solution bottle and a pure water bottle through pipelines. The gas storage tank is connected with a pneumatic pump through a pipeline. By means of the rapid vertical type plate cleaning machine, cleaning time is remarkably shortened; work efficiency is improved; and work intensity is lowered.

Description

Technical field [0001] The invention relates to a rapid vertical plate washer for microporous reaction plates. Background technique [0002] In modern medical tests, microplate readers are widely used, mainly used to detect hepatitis A, hepatitis B, hepatitis C and AIDS and other test items that require a greater risk of infection. The current processing process of the enzyme-labeled microwell reaction plate in the hospital laboratory It is divided into two parts. The first step is to use a device to repeatedly inject / aspirate the cleaning solution into the micropores for cleaning; the second step is to use a manual method or a device for spin-drying to remove residues in the micropores Of cleaning waste. [0003] At present, the plate washer on the market uses a set of cleaning needles and at the same time cleans one enzyme-labeled microwell reaction plate at a time, which is low in efficiency. Some laboratories use manual clapping (using the inertia generated during clapping) t...

AI Technical Summary

Problems solved by technology

Some laboratories adopt the method of manual clapping (using the inertia generated when clapping) to remove residual waste liquid. This method requires laboratory operators to directly operate the enzyme-labeled microwell reaction plate. The disadvantage of this method is that the waste liquid is easy to splash and cause damage The secondary pollution of the environment increases the risk of infection for operators, and the efficiency of removing residual waste liquid is low and difficult to remove.

In addition, some plate washing machines use centrifugal drying to remove residual waste liquid. This method is better than manual clapping in terms of removal efficiency and removal effect, but this method is directly centrifugal after filling the cleaning solution. Dry, if you need to clean for many times, add cleaning solution after drying each time, repeat the drying operation, this method greatly reduces the cleaning efficiency
