Common problems and solutions when using laboratory glassware washer
The laboratory glassware washer may encounter various common problems during use. If these problems are not resolved in a timely manner, they may not only affect the efficiency of bottle washing, but also have a negative impact on the cleanliness of the laboratory and the accuracy of experimental results. Here are some common problems and their solutions:
Slow heating up
Possible reasons: The condensed water from the heater was not discharged smoothly or there was a significant accumulation of scale on the heater.
Solution: Open the bypass valve of the steam trap to drain the condensed water, and regularly check and remove the scale on the heater to ensure its good thermal conductivity.
Possible reasons: insufficient cleaning solution, abnormal operation of water pump, or accumulation of filter debris.
Solution: Increase the cleaning solution to raise the liquid level, check and handle water pump faults, and regularly clean the filter to reduce resistance.
Possible reasons: Quality issues with the glassware itself, instrument malfunctions, or low bottle temperature during bottle insertion.
Solution: Replace the vessel with a qualified one, conduct a comprehensive inspection of the instrument, identify the cause of the malfunction and solve it in a timely manner. Increase the temperature of the bottle before feeding to reduce damage caused by sudden temperature changes.
Possible causes: nozzle blockage, excessive detergent foam or poor detergent formula.
Solution: dredge the nozzle in time, improve the detergent formula to reduce foam, and ensure that the cleaning effect meets the experimental requirements.
Possible reasons: Improper use of cleaning agents or unreasonable cleaning program settings.
Solution: Ensure the correct amount of cleaning agent is used and follow the manufacturer's instructions to adjust the cleaning procedure appropriately, including cleaning time and temperature. In addition, perform additional rinsing steps to ensure better removal of cleaning agent residues.
Possible reason: Poor water quality may cause scale and water stains, reducing cleaning effectiveness.
Solution: Use high-quality water sources such as deionized water or reverse osmosis water to reduce the occurrence of water quality problems. Regularly maintain the water treatment system, replace filter cartridges and clean nozzles to ensure pure water quality.
Possible reasons: Prolonged use may cause malfunctions or component damage to the cleaning machine.
Solution: Regular maintenance and repair, replace severely worn parts according to the manufacturer's recommendations. Check the status and function of the cleaning machine before use to ensure that all components are working properly. If any malfunction is found, promptly contact professional technicians for repair.
Possible reason: Improper operation may cause the cleaning machine to malfunction or cause other problems.
Solution: Carefully read the operation manual of the cleaning machine and operate it correctly according to the instructions. Train and remind laboratory staff to follow correct procedures and safety regulations. Regularly conduct operational skills training to ensure correct operation of the cleaning machine.
Possible reasons: The cleaning machine involves chemicals and high temperatures, which may cause accidents and injuries if operated accidentally.
Solution: Implement necessary safety measures, including wearing personal protective equipment (such as gloves, goggles) and following chemical safety operating procedures. Ensure the safety and reliability of the cleaning machine equipment, with a safety control system and emergency stop device in place.
