Iodine Flask

Product Code : SCL-LG-11989

Iodine Flask (SKU SCL-LG-11989) is a stoppered borosilicate glass flask for iodine determination and related iodometric procedures, offered in 250 mL and 500 mL capacities. The ground-glass stopper keeps volatile iodine in the flask while a reaction stands, which is why analytical chemistry classes, pharmacy colleges and testing laboratories use it. Science Lab Supplies, working from Ambala, India, supplies it to schools, colleges, laboratories, tender contractors and distributors.

Specifications

The flask is blown from borosilicate glass with thick, uniform walls and carries white enamel printing on the body. It closes with a ground joint and matching stopper, and each capacity is listed with 24/29 and 29/32 joint-size options, so buyers choose the combination they need.

Applications and Experiments for the Iodine Flask

An iodine flask is chosen when a titration involves liberated iodine that could escape before it is measured. The stoppered flask lets the reaction stand closed, after which the iodine is titrated. It is standard glassware for iodometric and iodimetric work in colleges, pharmacy labs and oil and food testing.

• B.Sc. analytical chemistry: iodometric titrations such as the estimation of copper.
• B.Pharm pharmaceutical analysis: iodometric and iodimetric assays.
• Oils and fats analysis: determining the iodine value of an oil.
• Supervised demonstrations of iodine-based redox reactions.

Follow the safety rules for iodine and the reagents used, keep the ground joint clean so the stopper does not stick, and never heat or pressurise the closed flask.

Standard Scope of Supply

Each flask comes with its compatible stopper, in the capacity and joint size you select. Burettes, pipettes, reagents, stands, clamps and other measuring apparatus are not part of the supply; name both the capacity and the joint size when you ask for a quotation.

Packing, MOQ and Lead Time

Order a single flask for a testing bench or a mixed quantity of 250 mL and 500 mL flasks for a class; either way the quotation shows packing, delivery time and price for exactly what you listed. A burette and stand for a full titration apparatus set can join the same quote.

Science Lab Supplies holds an Importer-Exporter Code as a registered exporter, so it can ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. Reach us via the contact page, place items in the enquiry cart, or check the lab tender page for bulk institutional orders.

Frequently Asked Questions

What is an iodine flask used for?
It is used for iodine determination and iodometric titrations, where the stopper keeps liberated iodine inside the flask until it is titrated. Oil and fat laboratories also use it to find iodine values.

Which capacities and joint sizes are offered?
The flask is offered in 250 mL and 500 mL, with 24/29 and 29/32 joint options. State the capacity and joint combination you need when you enquire.

Is the stopper included?
Yes. Each flask has a ground joint and is supplied with a compatible stopper. Burettes, pipettes and reagents are ordered separately.

Who supplies the Iodine Flask?
It comes from Science Lab Supplies in Ambala, India, which supplies analytical glassware to colleges, pharmacy institutes and testing laboratories and can quote it with other titration items for tenders.

Related Titration Glassware

Iodometric work is a titration, so the flask is only one part of the bench. Accurate delivery of the titrant and sample, and a supply of stored standard solutions, matter just as much. The four items below complete a typical titration set-up.

• Borosilicate Burette with Rota Stopcock — delivers the titrant.
• Volumetric Pipette 5ml — transfers a fixed volume of sample or reagent.
• Borosilicate Conical Flask — for titrations that do not need a stopper.
• Glass Reagent Bottle With Screw Cap — stores standard solutions between sessions.
