The most common way to clean used glassware in a lab is to hand wash it. People think that hand washing is more economical than investing in a lab glassware washer. The opposite is true, and the direct costs of hand washing glassware (water, usage, and labor costs) make a strong case for automated machines to save money in addition to providing consistently clean glassware. Next, we’ll talk about how glassware washing machines work to help you better understand this equipment.

Cleaning principle of Laboratory glassware washers

The product’s cleaning principle consists of high-pressure water flow cleaning and chemical agent immersion cleaning.

  1. Pre-cleaning: the first tap water for 1 time through the spray arm of the vessel for a high-pressure cycle rinse; the residues in the bottle and dish are rinsed off after washing the dirty water. (Conditional laboratories can use pure water instead of tap water)
  2. Main cleaning: into the tap water for the second time, heating cleaning. The glassware washer automatically adds an alkaline cleaning agent through the spray arm on the bottle and dish to continue the high-pressure cycle of rinsing and washing after the discharge of dirty water.
  3. Neutralization cleaning: into the tap water for the third time, the cleaning temperature is about 45 ° C. Equipment automatically adds acidic cleaning agent through the spray arm on the bottle and dish, continues the high-pressure rinsing cycle after washing and drains the dirty water.
  4. Rinsing: Rinsing is a total of 3 times;
    Into the tap water, select heating rinsing;
    Into the pure water, select heating rinsing;
    In pure water rinsing, select heating rinsing; the rinsing water temperature can be set to 93 ° C, which is generally recommended to be 75 ° C.
  5. Drying: Rinsing completed bottles in the heating cycle, blowing steam, condensation, and discharge through fast and clean drying inside and outside the vessel while avoiding clean secondary pollution.
    Of course, the above cleaning process is just a routine process. Glassware washers can be based on the specific needs of the laboratory vessels, so select the cleaning program. The equipment is fully automated, and no personnel are required to operate after the equipment has started the cleaning function.

The use of laboratory bottle washing machine

  1. First of all, you need to clean the machine and make sure that the power line, water line and other connections are normal;
  2. Place the experimental bottles or glassware to be cleaned in the machine, taking care not to overlap or touch each other;
  3. Select the appropriate cleaning program and cleaning agent according to the actual situation and set up by the instructions;
  4. Start the machine and wait for the cleaning to be completed.

Precautions for laboratory bottle washing machine

  1. Before using the product, you need to read the manual carefully to understand the use of the machine and precautions;
  2. In the process of use, keep the machine clean and hygienic, regular maintenance;
  3. Pay attention to safety when using chemicals. Avoid contact with skin and eyes;
