Flask Pear shape with Two Neck
Product Code : LSK-LF-10427
Flask Pear shape with Two Neck (SKU LSK-LF-10427) is a small borosilicate glass flask with a pear-shaped body, a 14/23 centre neck and a side neck set at 25°. The angled side neck lets a thermometer, gas inlet or addition funnel sit beside the main fitting in small-scale work. Organic chemistry teaching and research labs use it. Science Lab Supplies arranges supply of this flask from Ambala, India for colleges, universities, tender contractors and distributors.
Specifications
The listed 50 mL version has a 14/23 centre socket and an overall height of 100 mm, with the side neck angled at 25° from the centre neck. The pear shape keeps a small volume pooled in the base, which helps when only a few millilitres are being heated or distilled.

Applications and Experiments for the Two Neck Pear Flask
Two necks allow two things to happen at once: a condenser or still head on the centre neck and a thermometer, inlet or funnel on the angled side neck. For small-scale synthesis and distillation this makes the flask a practical piece of laboratory distillation apparatus in India.
- M.Sc. and B.Sc. organic chemistry: semi-micro reactions that need a thermometer or reagent inlet beside a condenser.
- Small-scale distillation with the liquid temperature monitored through the side neck.
- Research labs: running small reactions under a gas inlet while refluxing.
Standard Scope of Supply
Each flask is supplied as a single two-neck pear-shaped flask, as described above. The side-socket size and any capacity other than 50 mL are not given in the listing, so state your requirement and the quotation will confirm exactly what is supplied.

Frequently Asked Questions
Why is the side neck angled at 25 degrees?
The angle moves the side fitting away from the centre neck, so a thermometer or inlet and a condenser can both be fitted without touching each other.
How does it differ from the single-neck pear flask?
The single-neck model has one socket only (14/20 or 24/40). This flask adds an angled side neck and has a 14/23 centre socket, allowing two fittings at once.
What is the side socket size?
The side-socket size is not given in the listing. Please ask through the contact page and we will confirm it with your quotation.
Who supplies this flask?
Science Lab Supplies supplies it from Ambala, India, for single orders, lab sets and tender quantities.
