ELISA reader washing machineAlso known as a washing machine, it is a medical device specifically designed for cleaning enzyme-linked immunosorbent assay (ELISA) plates and is usually used in conjunction with an ELISA reader. Its main function is to clean some residual substances after enzyme-linked immunosorbent assay (ELISA) plate detection, in order to reduce errors caused by residues in the subsequent detection process. The washing machine has been widely used in the cleaning of enzyme-linked immunosorbent assay (ELISA) plates in hospitals, blood stations, health and epidemic prevention stations, reagent factories, research laboratories and other places.
The working principle of the enzyme-linked immunosorbent assay (ELISA) plate washing machine is mainly to inject cleaning solution into the micropores of the ELISA plate through high-pressure water flow or negative pressure suction, and to clean the residual substances inside the micropores through multiple flushing and liquid suction actions. At the same time, the washing machine can also adjust parameters such as the type of cleaning solution, temperature, and flushing frequency as needed to achieve the best cleaning effect.
ELISA reader washing machineUsage method:
1、 Power on preparation
Power and initialization: Plug in the power cord, turn on the power switch on the back of the instrument, enter the initialization phase, and clean the pipeline with distilled water. After completion, enter the working state.
Check the washing solution and waste liquid bottle: Ensure that there is enough washing solution in the washing solution bottle, the waste liquid bottle has been emptied, all bottle caps are tightened, and the pipeline connections are correct.
Choose hair washing: Choose 8 or 12 washes according to the direction of the washing board, and ensure that the pipes are connected correctly.
2、 Place the enzyme-linked immunosorbent assay (ELISA) plate and set the parameters
Place the enzyme-linked immunosorbent assay (ELISA) plate: Place the plate to be washed steadily into the tray, ensuring that the number of holes in the plate rows matches the number of holes in the cleaning head. Cover with a protective cover to prevent contamination of the enzyme-linked immunosorbent assay (ELISA) plate during operation.
Set parameters: Press the "Wash/Stop" button to enter the parameter selection program. Parameters such as the type of microporous plate used (such as flat bottom type, UV type, etc.), plate washing method (plate circulation or strip circulation), plate washing times (usually 1-9 times, generally 3-5 times), number of Flat noodles to be washed, liquid dosage per hole, etc. can be set. After setting the parameters, press the "Wash/Stop" button to return to the parameter selection program.
3、 Plate washing operation
Start washing the board: The washing machine starts washing the board according to the set program, observing whether each hole of the microporous board is filled with washing solution. If individual holes are not filled, as long as the liquid volume is not less than 80%, it will not affect the quality of the washing board.
Pause and Continue: During the washing process, you can press the pause button to pause the washing, and continue washing after resolving the issue.
4、 Rinse the pipeline
Change liquid: After washing the board, replace the washing solution bottle with a distilled water bottle.
Flushing pipeline: Press the "Flushing Pipeline" button, set the flushing pipeline time, and start flushing the pipeline. Rinsing with distilled water can effectively prevent pipeline crystallization and prevent clogging of the cleaning head.
5、 Shutdown and maintenance
Turn off power: After flushing, turn off the power, clean the instrument workbench, and cover it with a protective cover.
Daily maintenance:
Timely replenishment and emptying: When the washing solution in the washing solution bottle is insufficient, it should be replenished in a timely manner. When the waste liquid bottle exceeds two-thirds of its capacity, it should be emptied in a timely manner to avoid overflow and pollution.
Prevent cross contamination: Use a liquid dispenser that cannot be mixed with the added liquid head to prevent cross contamination.
Operating standards: Strictly follow the instructions of the reagent kit to ensure the accuracy of reaction time and conditions. Do not touch the enzyme plate during the measurement process to avoid squeezing or affecting the measurement results.
Cleaning and disinfection: After the instrument comes into contact with contaminated or infectious substances, it should be cleaned and disinfected in a timely manner. Regularly clean the pipeline with distilled water to prevent blockage or crystallization of the washing plate head and pipeline. When not in use for a long time, remove the washing head and soak it in distilled water, and empty the waste liquid bottle.
Troubleshooting: In the event of a technical malfunction, promptly contact the manufacturer and do not disassemble the enzyme-linked immunosorbent assay (ELISA) reader on your own.
