Graduated Flask with Fixed Stoppers
Product Code : SCL-CL-11899
Graduated Flask with Fixed Stoppers (SKU SCL-CL-11899) is a one-mark glass volumetric flask in 50, 100 or 500 ml, calibrated to hold its stated volume exactly at the specified liquid temperature. With it, chemistry students can make up standard solutions and accurate dilutions in school, college and analytical labs. Science Lab Supplies arranges supply from Ambala, India, and can quote it for schools, colleges, training institutes, tender contractors and distributors.
Specifications
This one-mark volumetric flask is set out fact by fact in the table below. In short, it is a glass flask with a long narrow neck and a single calibration line, closed through a ground glass taper joint by a matching plastic stopper, and calibrated to its stated volume at the specified liquid temperature.

Applications and Experiments for the Volumetric Flask
A volumetric flask is the vessel for any solution that must have an exact concentration: the solute is dissolved, the flask is filled to the mark and the stoppered flask is inverted to mix. It suits CBSE/NCERT Class 11–12 volumetric analysis and B.Sc. analytical chemistry practicals.
- Class 11–12: preparing standard oxalic acid or Mohr’s salt solutions after weighing the solute on a Semi-Analytical Balance with Box of Weighing Stones.
- B.Sc. analytical chemistry: making primary standards and serial dilutions, with aliquots drawn by Graduated Pipettes with Different Pupils.
- Rinsing the last traces of solute into the neck with a Plastic Washing Bottle (Pisetta).
- Laboratory-technician training: practising correct meniscus reading at the mark.
Liquids expand and contract with temperature, so fill the flask at the calibration temperature and never heat it; dissolve warm solutes in a beaker first and let the solution cool.
Standard Scope of Supply
Each Graduated Flask with Fixed Stoppers is one glass one-mark flask with its matching stopper, in 50 ml, 100 ml or 500 ml as ordered. Funnels, droppers and wash bottles for filling to the mark can be added to the same quotation as separate items.
Packing, MOQ and Lead Time
Whether a school needs a few flasks for the demonstration bench or a college needs one per student in each size, the quotation states packing, delivery time and price for the quantity asked. Ask also for the school volumetric flask in India price for other glassware on your list.
Science Lab Supplies holds an Importer-Exporter Code and is able to ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. To have the three capacities priced, note the quantities on the contact page or in the enquiry cart; for a volumetric glassware tender, the lab tender page sets out the route.
Frequently Asked Questions
What is the difference between this flask and a conical flask?
This flask has one calibration mark and holds an exact volume at the stated temperature, so it serves standard solutions. A conical flask carries only approximate graduations and is meant for mixing and titrating.
Which sizes can I order?
The flask comes in 50 ml, 100 ml and 500 ml. The 100 ml size suits most school standard solutions, while the 500 ml size is useful when a larger stock solution has to be prepared.
Why does temperature matter?
The flask is calibrated at a specified liquid temperature. A warmer or cooler liquid occupies a different volume, which changes the concentration of the solution you prepare.
Who supplies the Graduated Flask with Fixed Stoppers?
It is part of the volumetric glassware that Science Lab Supplies quotes from Ambala, India; the flask can be priced on its own or alongside the pipettes, funnels and bottles a chemistry lab needs.
