The things about washing in the laboratory

The first question: How much time needed to wash the bottles in one day of scientific research?

Friend 1: I did the high-temperature organic liquid phase synthesis for about one and a half years, and it takes about 1 hour to wash bottles every day, which accounts for 5-10% of scientific research time. I also can be regarded as a bottle-washing skilled worker.
Regarding bottle washing, I have specifically discussed with other people, mainly four-neck bottles are difficult to clean, the buffer bottles are easy to clean.

Friend 2:
Only one 5ml sample tank (beakers) is need to be washed, but it must be washed with deionized water-25% nitric acid-50% hydrochloric acid-deionized water under 130℃. Each wash takes 5 days, on average every day Wash 200-500 pcs.

Friend 3:
Two large pots of petri dishes, triangular flasks, and other types of glassware, you can wash about 70-100 in a day. Generally, laboratory ultrapure water machines are used for water production and cleaning, so the cleaning volume is not particularly large.

Friend 4:
Recently, I have been doing miscellaneous work in the laboratory. Because it is organic synthesis and the requirements are strict, I use a lot of glassware. Generally, it takes at least an hour to wash, which feels very boring.

Here are only excerpts from these 4 friends’ answer, which all reflect the following common points: 1. Manual cleaning 2. Large quantity 3. Time-consuming, so faced with such a large number of time-consuming bottle and dish cleaning, everyone has How do you feel?

Question 2: How do you feel about washing bottles and dishes for a long time?

 Friend A:

I stayed in the laboratory from morning to night all day. It can really count as 007, washing bottles and bottles, bottles that can’t be washed.
A few freshmen in the laboratory are that as long as the test tube of the bottle that has been touched by hand must be washed… Washing powder ultrasonically for two hours, tap water for two hours, and pure water for another two hours. Once the test tube is washed, three test tubes will be broken by ultrasound. One part (there is a trash bin next to it for broken glass, which was filled in a week)…I once watched a freshman wash more than 50 bottles from morning to evening.

Friend B:
I feel that washing the bottles can really hone people’s patience, but those experiments just go through the columns and it takes a lot of time, and it takes time to wash the bottles, and the uncleanness also affects the experiment. If you use them all at once, I feel that you can really save a lot of time to do other steps, and it can be regarded as a small increase in the speed and efficiency of the entire experiment.

After hearing the fair answers from these two friends, I still felt annoyed about washing a pile of glass bottles. Do you feel the same? So why not choose to use a fully automatic bottle washer?

The third question: What do you think of manual cleaning vs. bottle washing machine?

Friend 1:
Personally, every laboratory that does wet chemistry should be equipped with a bottle washer, just like every household should be equipped with a washing machine and a dishwasher. It is necessary to save students’ time and do more meaningful things, including but not limited to, reading literature, analyzing data, thinking, investing and managing money, falling in love, going out to play, internships, etc.
I heard that many high-throughput experiments in biology can be done automatically with equipment, but some research groups take advantage of the low cost of graduate students and let graduate students operate manually. Such behavior is outrageous.
In short, I advocate that all repetitive tasks that can be done by machines in scientific research should be done by machines, and students should be allowed to do scientific research instead of being cheap labor.

Friend 2:
What is the effect of washing special-shaped containers such as NMR tubes/Shrek bottles/small medicine bottles/sand core funnels? Do the test tubes have to be inserted one by one or can they be bundled and put in (similar to the general alkaline tank process)?
(Don’t buy the big head and throw it at the labor…

Friend 3:
The bottle washer needs money to buy, the students don’t need money to buy it [cover face]
The answers of three friends are selected above. Some people strongly advocate the replacement of manual bottle washing machines, some have doubts about the cleaning ability of bottle washing machines, and those who don’t know much about bottle washing machines. It can be seen from the above that everyone has not understood or questioned the bottle washer.


Turning back to the main text, here is the official model to answer the third question:
Advantages of laboratory glassware washer:
1. High degree of full automation. It only takes two steps to clean a batch of bottles and dishes: Put the bottles and dishes-one-click to start the cleaning program (and contains 35 standard programs and manually editable custom programs to meet the needs of most laboratory customers). Automation frees the hands of experimenters.
2. High cleaning efficiency (automatic glassware washer batch work, repeated cleaning process), low bottle breaking rate (adaptive adjustment of water flow pressure, internal temperature, etc.), wide versatility (accommodating a variety of sizes and shapes of test tubes, Petri dishes, volumetric flasks, conical flasks, graduated cylinders, etc.)
3. High safety and reliability, pre-installed imported explosion-proof safety water inlet pipe, pressure and temperature resistance, not easy to scale, with anti-leakage monitoring valve, the instrument will automatically close when the solenoid valve fails.
4. High level of intelligence. Important data such as conductivity, TOC, lotion concentration, etc. can be presented in real time, which is convenient for relevant personnel to monitor and master the cleaning progress and connect the system to print and save, which provides convenience for later traceability.
