Glass Dropper Pipette 6

Product Code : SCL-LG-12007

Glass Dropper Pipette 6 (SKU SCL-LG-12007) is a 6-inch (150 mm) borosilicate glass dropper with a tapered tip and a removable rubber bulb, used to draw up and release small amounts of liquid drop by drop. Students add indicators with it, technicians transfer reagents, and biology classes use it for staining slides. From Ambala, India, Science Lab Supplies offers these droppers to schools, colleges, institutes, tender contractors and distributors.

Specifications

The dropper tube is borosilicate 3.3 glass with a fire-polished tapered nozzle for even drops, and it is not graduated. A black rubber bulb fits over the open end. With the bulb removed, the glass tube can be autoclaved or dry-heat sterilised up to 140 °C.

Applications and Experiments for the Glass Dropper Pipette

A glass dropper pipette is used wherever a few drops matter more than an exact volume: adding indicator before a titration, testing solutions in test tubes, placing stain on a slide or topping a volumetric flask up to the mark. At 150 mm it reaches into test tubes, small beakers and narrow-necked bottles.

• CBSE/NCERT Class 6–10 science: food tests, indicator tests on acids and bases, and simple reactions in test tubes.
• Class 11–12 chemistry: adding indicator and reagents drop-wise in titration and salt-analysis practicals.
• Class 11–12 and B.Sc. biology: staining onion peel, cheek cells and other slide preparations.
• College and testing labs: small-volume transfer of reagents and samples.

Frequently Asked Questions

What size is this dropper pipette?
The glass tube is 6 inches, or 150 mm, long. The "6" in the product name refers to this length.

Can the dropper be sterilised?
The borosilicate glass tube can be autoclaved or dry-heat sterilised up to 140 °C after the rubber bulb is removed. Clean the bulbs separately at low temperature so the rubber does not crack.

How do I stop liquid getting into the bulb?
Keep the filled dropper pointing downwards and never lay it flat or upside down. Liquid in the bulb can damage the rubber and contaminate the next sample.

Who supplies the Glass Dropper Pipette 6?
The droppers are supplied by Science Lab Supplies from Ambala, Haryana, India. Schools, colleges, laboratories and distributors get quotations directly for one pack or many.
