Pear Shaped Flask Manufacturer,Supplier and Exporter in India

Pear Shaped Flask (Product Code: SLE/GFL/09) is a borosilicate glass flask with a tapering, pear-shaped body that lets a distillation be continued until only a small bulk of liquid is left in the flask. Working down to that small volume reduces losses from thermal decomposition, which makes the flask well suited to semi-micro distillations in college, university and research chemistry labs. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as one of the specialised pieces of chemistry lab glassware in its flask range.

Specifications

Typical Use

The flask comes into its own when the quantity being distilled is small — purifying a few millilitres of a synthesised liquid in an organic chemistry practical, or recovering a solvent from a small extract. As the level falls, the remaining liquid collects in the narrow lower part of the pear instead of spreading into a thin film across a wide base, so the last portion can still be distilled rather than overheated. Like other borosilicate laboratory glassware, it copes with the repeated heating and cooling of routine lab work.

The 50 ml and 100 ml sizes are the usual choice for semi-micro work, while the 250 ml and 500 ml flasks handle larger crude batches that will later be reduced. Heat in a water or oil bath for even warming of the tapered base, clamp the flask by its neck, and stop before the flask boils dry. The graduations give a quick visual check of the volume remaining.

Useful companions for small-scale distillation with this flask:

• Pear Shaped Flask with Two Neck — the same shape with an extra angled side neck for a thermometer or addition
• Liebig Condenser — condenses the vapour driven off from the flask
• Water Bath — gentle, even heating around the tapered base
• Three Prong Swivel Clamp — grips the neck and can be angled to line up with the condenser
• Round Bottom Flask — the better choice for larger routine batches

Frequently Asked Questions

Why use a pear shaped flask instead of a round bottom flask?
Because the pear shape lets you distil down to a small bulk, which reduces losses from thermal decomposition at the end of a run. For larger volumes where the final residue matters less, a round bottom flask is the simpler option.

What sizes are available?
50 ml, 100 ml, 250 ml and 500 ml. Mixed-size orders can be quoted together.

Does the neck have a ground-glass joint?
The neck finish and joint size are not specified in our current listing for this flask. Please contact us with the joint size your condenser uses and we will confirm what can be supplied.

Can the graduations be used for accurate measurement?
They are intended as a guide to the volume in the flask. For accurate volumes, measure the liquid with volumetric glassware before transferring it.

What information should an institutional quotation include?
List the capacities and quantities required, the delivery address and any tender reference, and send it through our contact page or enquiry cart.

Do you ship outside India?
Yes, ScienceLab supplies laboratories and distributors in India and international markets; export packing and shipping terms are confirmed with the quotation.
