How to Maintain the School Chemistry Lab Equipment?

Each piece of equipment in the chemistry lab needs to be maintained properly:

Glassware

1. Beaker – A beaker is a simple container used for mixing, stirring, and heating chemicals. After use, rinse glass beakers thoroughly with soap and water. Then, store them in the lower rack of a cabinet with glass doors. This way, dust cannot fall into the beaker and disrupt future experiments. Moreover, storing them properly ensures cleanliness, prevents contamination, and keeps the beakers ready for the next use. Therefore, always follow this routine to maintain accurate and safe experimental conditions.
2. Conical Flask (Erlenmeyer Flask) – Used for mixing and heating solutions with reduced risk of spills. Store and clean flasks like beakers. 
3. Test Tubes – Test tubes are small glass tubes used for holding, mixing, and heating substances. After use, clean them properly. Then, store them in boxes with holders to prevent breakage. Additionally, always keep these boxes in a well-ventilated, closed space, such as a glass-door almirah or cupboard.

4. Test Tube Holder – A clamp used to hold test tubes during heating. Keep ample holders in the lab, so that all students have enough holders to use during experiments. If enough holders aren’t there, students resort to hacks like using paper holders as a makeshift or using the test tube as is during heating. This is very risky, because the paper can catch fire, or the reagents in the tube can boil out, harming the student. Hence, test tube holders are a must for every school chemistry lab. 
5. Measuring Cylinder (Graduated Cylinder) – Used to measure liquid volumes accurately. Store them along with glassware, ensure dust and humidity does not affect the equipment. 
6. Watch Glass – A concave glass used for evaporating small amounts of liquid or covering beakers. Store like other glassware. 

Additional Equipment

1. Bunsen Burner – A gas burner used for heating substances. Teach students to stop the gas supply after use.
2. Wire Gauze – A mesh placed over a tripod stand to distribute heat evenly.
3. Crucible and Lid – A heat-resistant container for high-temperature heating.
4. Evaporating Dish – Used to evaporate liquids and concentrate solutions.
5. Pipette – A tool for transferring precise amounts of liquid. Assign one mouth pipette to each student. Mouth pipettes are unhygienic if shared. 
6. Burette – A long graduated tube used in titration to measure liquid volume precisely. Teach students to handle the burette carefully. Students might break the long glass burette by mistake. Fill the burette by keeping the burette and stand setup on the ground. Then place it on the benchtop to perform titration drop by drop. 
7. Dropper – A small tool for adding liquid dropwise. 
8. Glass Stirring Rod – Used for stirring solutions manually. Replace broken or cracked glass rods as they can cause injury. 
9. Funnel – Used for transferring liquids and filtering mixtures.
10. Filter Paper – A porous paper used to separate solids from liquids. Keep them inside packed boxes, to protect from dust and humidity. 
11. pH Paper – A strip of paper that changes color to indicate acidity or alkalinity. You must keep them absolutely dry.

You might be wondering how to deal with humidity in tropical countries. The best way is to store the apparatus or equipment for the school chemistry lab in a closed cupboard and then put silica gel in corners in the cupboard. It will absorb the moisture, keeping the apparatus dry, hence rust and bacteria free.
