Using Reagent Bottles In Lab

Reagent bottles are one of the indispensable experimental supplies in the laboratory. Its function is to store, transport and dispense chemical reagents and solutions. Some details need to be paid attention to when using reagent bottles to ensure the accuracy and safety of the experiment. This article will introduce the use and precautions of reagent bottles in the laboratory.

Steps for usage:

1. Prepare the reagent bottle: Select the appropriate reagent bottle and make sure it is clean and sterile. Place filters under caps as needed to avoid contamination.

2. Reagent filling: drop the reagent into the reagent bottle through a vertical dropper. For high concentrations of acids, bases or toxic reagents, special tools and techniques are required to ensure safety.

3. Close the reagent bottle: Tighten the bottle cap by hand to ensure that the O-ring on the bottle cap is completely sealed. For long-term storage or reagents that need to be transported, the reagent bottle can be placed in an amber bottle to avoid light.

4. Store the reagent bottles: store the reagent bottles in the correct place according to the requirements of the reagents and the relevant laboratory rules and regulations. It should be noted that different reagents need to comply with different regulations when storing. Generally speaking, reagent bottles need to be stored in a place protected from light, moisture, dryness and good ventilation.

Precautions:

1. Avoid spillage: When filling the reagent, be careful not to spill the reagent out of the reagent bottle to avoid contamination and danger.

2. Clear label: clearly label the reagent bottle, including reagent name, concentration, storage date and other information. This helps identify reagents and track reagent usage.

3. Do not reuse: reusing reagent bottles may cause cross-contamination, which is not safe. Relevant regulations and standard disinfection procedures for reagent bottles should be followed.

4. Store away from light: Chemicals that need to be stored away from light should be stored in amber bottles and kept away from light sources.

In short, the use method and precautions of reagent bottles in the laboratory are very important to ensure the accuracy and safety of experimental results. Understanding these details can not only better protect the safety of laboratory workers, but also help to improve the efficiency and service life of reagents, thereby reducing experimental costs.
