Flask Pear Shape Single Neck
Product Code : LSK-LF-10419
Flask Pear Shape Single Neck (SKU LSK-LF-10419) is a heat-resistant borosilicate glass flask with a pear-shaped body and one ground-joint neck, made for semi-micro distillations. The tapering bottom lets a liquid be distilled down to a very small residue. Organic chemistry and pharmacy labs use it for small-scale work. Colleges, universities, training institutes, tender contractors and distributors can have it quoted and dispatched by Science Lab Supplies from Ambala, India.
Specifications
Six versions are listed: 25, 50, 100 and 200 mL with a 14/20 socket, and 50 and 100 mL with a 24/40 socket. All are single-neck, pear-shaped flasks in borosilicate glass, so a small volume collects in the narrow base instead of spreading thinly over a round bottom.

Applications and Experiments for the Pear Shape Flask
A pear-shaped flask is the vessel of choice when only a few millilitres must be distilled or concentrated, because the liquid stays pooled in the narrow base and keeps covering the heated surface. It is a useful part of any laboratory distillation apparatus in India set up for small quantities.
- B.Sc. and M.Sc. organic chemistry: semi-micro distillation and purification of small product samples.
- B.Pharm. and M.Pharm. practicals: concentrating small extracts and reaction mixtures.
- Research labs: removing solvent from small fractions down to a minimal residue.
Standard Scope of Supply
Each Flask Pear Shape Single Neck is supplied as a single flask in the capacity and socket size ordered. Condensers, still heads, stoppers and clamps are separate ground-joint items and can be added to the quotation where you need a complete distillation assembly.
Packing, MOQ and Lead Time
Request a quotation for one flask or a mixed set of sizes for a practical class, and it will show packing, delivery time and price for what you asked for. Other borosilicate laboratory glassware in India, such as round-bottom and two-neck flasks, can join the same order.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Use the enquiry cart to list sizes, send questions from the contact page, or check the lab tender page for institutional tenders.
Frequently Asked Questions
Why use a pear-shaped flask for small distillations?
The tapering base keeps a small volume of liquid together, so it can be distilled down to a small residue without the flask running dry over a wide surface.
Which socket sizes are available?
The 14/20 socket is listed on the 25, 50, 100 and 200 mL flasks, and the 24/40 socket on the 50 and 100 mL flasks. Match the socket to your condenser or adapter.
Does this flask have more than one neck?
No. This model has one neck only, for simple distillation or concentration. A multi-neck flask is needed when a thermometer, inlet or addition funnel must be fitted at the same time.
Who supplies this flask?
Science Lab Supplies supplies it from Ambala, India, for single orders, class sets and tenders.
