How much water and electricity consumption does a lab glassware washer require? Let’s compare it with manual cleaning

In laboratories, glassware washing machine have gradually replaced manual cleaning as the mainstream cleaning method. However, for many laboratory workers, the water and power consumption of bottle washers is still a concern, and they believe that hand washing saves cleaning costs compared to bottle washing machines. This article will compare the water and energy consumption of manual cleaning and bottle washing to help you better understand this topic.

1. Evaluation of water and electricity consumption for manual cleaning:

Manual cleaning of glass bottles and other containers is a traditional method that requires laboratory staff to clean them one by one. In this process, water consumption is inevitable. Laboratory workers need to use a large amount of water to rinse glass bottles. Taking a 100ml volumetric bottle as an example, it needs to be rinsed once, brushed once with detergent, and rinsed three times with pure water. Calculated based on the full volume of cleaning water: 100ml* 5=500ml (but under normal circumstances, the water consumption of running the faucet is greater). At the same time, it also requires the use of an appropriate amount of chemical reagents for soaking time and reagent costs. In addition, manual cleaning requires a lot of time and labor, thus increasing the workload of laboratory workers.

2. Evaluation of water and power consumption of bottle washing machines:

Compared with manual cleaning, bottle washing machines are more standardized and automated in cleaning glass bottles. The bottle washing machine uses water spray mechanical action and chemical reagents to clean glass bottles and dishes, and can quickly clean multiple glass bottles and dishes. In this process, the bottle washing machine needs water to wash away the dirt and residue on the surface of the glass bottles, and it also needs to use an appropriate amount of electricity to drive the equipment.

The following is the water and electricity consumption calculation of the bottle washer: Taking the Aurora-F2 double-layer model as an example, more than 144 100ml volumetric bottles can be washed at the same time. The amount of water required to manually clean the same volume of volumetric bottles is 500ml*144= With a water volume of 72L, the standard program of Xibianzhe bottle washing machine is 4-step cleaning. Each step consumes 12L of water, 12*4=48L of water. Compared with manual cleaning, the water consumption is reduced by 33%. The amount of cleaning agent used is 0.2% of the water, which is 12*0.2%=24ml. Compared with manual cleaning, the consumption is reduced by 80%. Electricity consumption calculation: 3 kilowatt hours of electricity, 1.00 yuan per kilowatt hour, cost 3 yuan, plus Excluding the water and cleaning agent costs above, the bottle washing machine only costs 8-10 yuan to clean 144 100ml volumetric bottles at a time. Time cost: Manually cleaning one bottle takes approximately 30 seconds, and 144 bottles takes 72 minutes. The bottle washing machine only takes 40 minutes to clean and 25 minutes to dry, and the process does not require manual intervention.

Compared with manual cleaning, the bottle washing machine can significantly reduce cleaning costs when cleaning glass bottles. Therefore, for laboratory workers, using a bottle washing machine can not only improve cleaning efficiency, but also reduce laboratory operating costs and promote laboratory automation.
