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, which suits small-scale organic chemistry and pharmacy practicals. For colleges, universities, training institutes, tender contractors and distributors, Science Lab Supplies prepares quotations and arranges dispatch from Ambala, India.
Specifications
Six capacity and socket combinations of the pear-shaped flask appear in the table below. In short, the 25, 50, 100 and 200 mL flasks take a 14/20 socket, the 50 and 100 mL flasks also come with a 24/40 socket, and all are heat-resistant borosilicate glass, so a small volume pools in the narrow base.

Applications and Experiments for the Pear Shape Flask
A pear-shaped flask suits work where only a few millilitres must be distilled or concentrated, because the liquid stays pooled in the narrow base and keeps covering the heated surface. That makes it 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, with a still head or an Adapter (Alunge) connecting the flask to the condenser and receiver.
- B.Pharm. and M.Pharm. practicals: concentrating small extracts and reaction mixtures, warmed gently through a bath on an Electric Hot Plate.
- Research labs: removing solvent from small fractions down to a minimal residue.
Hold the flask at the neck in a Three Prong Glassware Holding Clamp, fill it no more than about half full, and stop heating before the last drops boil away.
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 can be added to the same quotation where you need a complete distillation assembly matched to the 14/20 or 24/40 socket you choose.
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. Send a socket-by-socket list through the contact page, save the flask in the enquiry cart while you gather other glassware, or turn to the lab tender page for bids made through a tender committee.
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, thinly covered surface.
Which socket sizes are available?
The 14/20 socket comes 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, still head or adapter before ordering.
Does this flask have more than one neck?
No. This model has one neck only, for simple distillation or concentration. When a thermometer or inlet must be fitted at the same time, the two-neck pear flask with its 25° side neck is the matching choice.
Who supplies this flask?
Quotations for this pear-shaped flask come from Science Lab Supplies in Ambala, India, and can cover a single flask, a class set across both socket sizes, or a full tender quantity.
