Bottle Top Dispenser
Bottle Top Dispenser (Product Code: SLE/LI/13) is a bottle-mounted liquid dispenser used to deliver repeated, preset volumes of reagents and solvents from 2.5 to 25 ml straight from the reagent bottle in chemistry, biology and quality-control laboratories. Technicians and students use it for routine additions during titrations and sample preparation, and it comes with S40, GL25, GL28, GL32 and GL38 bottle adapters. The dispenser is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Bottle Top Dispenser Used For?
A bottle top dispenser screws onto a reagent bottle so the same volume can be delivered again and again without pouring or pipetting. As part of chemistry lab equipment for practical classes, it speeds up adding acids, buffers or solvents to a row of flasks, and in quality-control work it keeps additions consistent from one sample to the next. The 2.5–25 ml range with 0.5 ml graduations covers volumes typical of titration and sample-preparation steps.
Keep the liquid within the listed limits — vapour pressure up to 500 mbar, viscosity up to 500 mm²/s, density up to 2.2 g/cm³ and temperature up to 40 °C — and ask us about chemical compatibility before dispensing aggressive reagents. Fit the adapter that matches your bottle neck, discard the first few strokes to prime the dispenser, and operate the piston smoothly to avoid air bubbles.
What to Specify When Ordering
- Your bottle neck thread, to confirm which of the S40, GL25, GL28, GL32 or GL38 adapters you will use.
- The reagents to be dispensed, so compatibility and the listed limits can be checked.
- The number of dispensers required.
- Whether reagent bottles should be quoted with the dispensers.
Supplier
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, supplies this dispenser from Ambala, Haryana, to schools, colleges, testing laboratories, dealers and importers.
