Iodine Flask
Product Code : LSK-LF-10424
Iodine Flask (SKU LSK-LF-10424) is a borosilicate glass flask with a ground joint and stopper, made for the determination of iodine in titrations where volatile iodine must not escape. It has a thick, uniform wall and white enamel printing, and comes in 250 and 500 mL sizes. It suits college chemistry, pharmacy and quality-control practicals. Science Lab Supplies arranges supply from Ambala, India, with quotations prepared for colleges, testing labs, tender contractors and distributors.
Specifications

Applications and Experiments for the Iodine Flask
In iodometric and iodimetric titrations, iodine released during the reaction can evaporate from an open flask and give low results. Stoppering the flask while the reaction stands keeps the iodine in solution until it is titrated, which is why it belongs in a proper titration apparatus set.
- B.Sc. analytical chemistry: iodometric estimation of copper and of available chlorine in bleaching powder, titrated from a Borosilicate Burette with Rota Stopcock.
- B.Pharm. and food science labs: determining the iodine value of oils and fats, with the sample weighed out in a Weighing Bottle.
- Quality-control labs: iodine-based titrations on samples, with burettes held in a Burette Stand With Fisher Clamp.
Standard Scope of Supply
Each Iodine Flask is supplied with its stopper, in 250 or 500 mL and with the 24/29 or 29/32 joint you specify. Burettes, pipettes and reagents can be added to the same quotation if you are setting up a complete iodometric titration bench.
Packing, MOQ and Lead Time
From a pair of flasks for one analyst to a batch for a full practical class, you can ask for a quotation that sets out packing, delivery time and price for that quantity. Other flasks from this laboratory glassware supplier in India can be combined in the same offer.
Holding an Importer-Exporter Code as a registered exporter, Science Lab Supplies is able to ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Analysts can request prices for both joints via the contact page, line up titration glassware in the enquiry cart, or consult the lab tender page when a purchase committee is involved.
Frequently Asked Questions
Why use an iodine flask instead of an ordinary conical flask?
The ground-joint stopper seals the flask while the reaction stands, so volatile iodine cannot escape before titration. An open flask can lose iodine and give low results.
Which sizes and joints are available?
The flask comes in 250 mL and 500 mL, each with a 24/29 or 29/32 ground joint. State the joint you need so that replacement stoppers and any other fittings match.
What is the flask made of?
It is made of borosilicate glass with a thick wall of uniform thickness, and the markings are printed in white enamel. A ground joint and matching stopper close the neck.
Who supplies the Iodine Flask?
Supply comes from Science Lab Supplies, an Ambala, India business that quotes this flask for individual analysts, complete class sets and formal tenders in either capacity and joint.
