Abstract
The invention discloses a laboratory glassware cleaning method. The method is characterized by comprising the following steps of removing substances accommodated in glassware, repeatedly flushing the glassware for 2 to 3 times by using tap water to remove residual substances, soaking the glassware in a soak solution for 5 to 7 days, after taking out the glassware, brushing the glassware with a test-tube brush, and repeatedly flushing and cleaning the clean glassware by using deionized water for 2 to 3 times to flush off substances, such as ions on the surface of glass. The glassware cleaned by the method disclosed by the invention is cleaner, and cations and anions are hardly stuck to the surface of the glass, so that the method is applied to precise experiments.
Description
Technical field
The present invention relates to the chemical experiment field, be specifically related to a kind of laboratory glassware cleaning method.
Background technology
In experimentation, especially in biology, the chemical experiment, some product or tunning can be bonded at the glassware surface tightly, in cleaning process, require a great deal of time and energy, can't be thoroughly with its removing, after glassware dried, its surface still can residually have some to lose stain, and some accurate experiments are had a strong impact on.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of laboratory glassware cleaning method, the glassware of cleaning is cleaner, and glass surface contains zwitterion hardly, is applicable to accurate experiment.
The invention discloses a kind of laboratory glassware cleaning method, it is characterized in that may further comprise the steps:
A kind of laboratory glassware cleaning method is characterized in that may further comprise the steps:
1) flushing
To process totally with the article that hold in the glassware of crossing, and repeatedly wash 2-3 time in the pond, flush away is remaining article wherein;
2) immersion liquid preparation
Get the lidded container of a large ceramic material or glass material, in it according to distilled water: the concentrated acid volume ratio is 20:1-2(v/v) add distilled water and concentrated acid, the overall accumulated amount of distilled water and concentrated acid is 2/3 of container capacity;
3) soak
Glassware after the flushing is put into and filled in the soak container, glassware is finished being immersed in the soak, soaked 5-7 days;
4) clean
Glassware is taken out from soak, be placed in the pond and wash with running water, scrub with test-tube brush simultaneously, until till scrubbing clean;
5) deionized water rinsing
Repeatedly wash the glassware that cleans up 2-3 time with deionized water, the ionic species of glass surface is removed in flushing.
Further, wherein the described glassware of step 1) is beaker, flask, triangular flask, culture dish, test tube, graduated cylinder, measuring cup.
Step 2 wherein) the lidded container volume of described ceramic material or glass material is 50L or 100L.
Step 2 wherein) described concentrated acid is one or both in concentrated hydrochloric acid, red fuming nitric acid (RFNA), the concentrated sulfuric acid; During for two kinds in concentrated hydrochloric acid, red fuming nitric acid (RFNA), the concentrated sulfuric acid, two kinds of sour volumes are that 1:1 (v/v) mixes.
Wherein the described deionized water of step 5) is made by the ultra-pure water preparing machine.
Compared with prior art, beneficial effect of the present invention comprise following some: 1, laboratory glassware cleaning method disclosed by the invention, can save a large amount of glasswares and scrub the time, save great effort; 2, the glassware of the present invention's cleaning, the glassware that cleans than conventional method is cleaner; 3, contain hardly zwitterion on the glassware that the present invention cleans, be applicable to accurate experiment.
The specific embodiment
Below in conjunction with the specific embodiment the present invention is further elaborated.
A kind of laboratory glassware cleaning method is characterized in that may further comprise the steps:
1) flushing
To process totally with the tunning that holds in the triangular flask of crossing, and repeatedly wash in the pond 3 times, flush away is remaining article wherein;
2) immersion liquid preparation
Get the ceramic cylinder with cover of a 50L, in the ceramic cylinder according to distilled water: the concentrated acid volume ratio is 20:1(v/v) add distilled water and concentrated hydrochloric acid, the overall accumulated amount of distilled water and concentrated acid is 33L;
3) soak
Triangular flask after the flushing is put in the ceramic cylinder, and triangular flask finished be immersed in the soak, soaked 7 days;
4) clean
Triangular flask is taken out from soak, be placed in the pond and wash with running water, scrub with test-tube brush simultaneously, until till scrubbing clean;
5) deionized water rinsing
The deionized water that makes with the ultra-pure water preparing machine is washed the triangular flask that cleans up 3 times repeatedly, and the ionic species of glass surface is removed in flushing.
