Glass Rods
Product Code : SCL-CL-11920
Glass Rods (SKU SCL-CL-11920), also called stirring rods, are solid, clear glass rods 20 cm long and 4 mm in diameter for mixing solutions, guiding liquids while pouring and spreading substances. They suit school, college and research labs alike. As a laboratory glassware supplier in India, Science Lab Supplies can send them from Ambala against quotations from schools, colleges, training institutes, tender contractors and distributors.
Specifications
Every property of the 20 cm by 4 mm stirring rod appears in the table below. In short, each one is a solid, clear glass cylinder that resists heat and laboratory chemicals, so it can stir warm solutions, guide a stream of liquid and then be rinsed clean for the next experiment.

Applications and Experiments for the Glass Rods
A glass rod can stir solutions in beakers, direct a stream of liquid into a funnel or narrow vessel without splashing, and spread or transfer small amounts of substances. It can also touch a drop of solution onto litmus or indicator paper during simple acid-base tests at school and college level.
- Class 6–8 science: stirring solutions to show dissolving and saturation.
- Class 9–10 science: guiding liquid into the funnel during filtration.
- Class 11–12 chemistry: transferring a drop of solution to Blue Litmus Paper or Red Litmus Paper in acid-base tests.
- B.Sc. practicals: stirring during precipitation and crystallisation in a 150 ml Porcelain Dish.
Standard Scope of Supply
Glass Rods are supplied as described above, each a 20 cm by 4 mm clear glass rod. The number of rods per pack is confirmed on the quotation, and beakers, funnels or filter paper can be added if you are stocking a complete mixing and filtration bench.
Packing, MOQ and Lead Time
Stirring rods can break or go missing, so spares can be quoted with the main order. Ask for a quotation for a few rods or a full laboratory supply; it states the packing, delivery time and price, and beakers, funnels or other school chemistry lab equipment in India can be added.
With its Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). The quickest way to a price for a stock of rods is a note on the contact page or an enquiry cart list; tender documentation is dealt with via the lab tender page.
Frequently Asked Questions
What size are these glass rods?
Each rod is 20 cm long and 4 mm in diameter, made of clear, solid glass. The slim diameter suits beakers, flasks and funnels, and the length keeps fingers clear of the liquid.
What are glass rods used for in the lab?
They can stir solutions, guide liquids when pouring into funnels or narrow vessels, spread substances and transfer drops of solution onto test papers, making them a versatile tool for chemistry practicals.
Who supplies the Glass Rods?
These rods are offered by Science Lab Supplies from Ambala in India, for schools, colleges and tender contractors, and beakers, funnels and other glassware can be combined with them on one quotation.
Can glass rods be used in hot solutions?
Yes. The glass is heat and chemical resistant, so the rods can stir hot solutions; handle them carefully, as glass can break if dropped, and let them cool before rinsing.
