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. Chemistry students and analysts use it to make up standard solutions and accurate dilutions. The flask is supplied by Science Lab Supplies, working from Ambala, India, to schools, colleges, training institutes, tender contractors and distributors.
Specifications
This is a one-mark volumetric flask of glass: a round body, a long narrow neck with a single calibration line, and a ground glass joint closed by a matching stopper, which the specification describes as plastic. It is calibrated to hold its stated volume at the specified liquid temperature.

Applications and Experiments for the Volumetric Flask
A volumetric flask is used whenever a solution 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 is required glassware for CBSE/NCERT Class 11–12 volumetric analysis and B.Sc. analytical chemistry.
- Class 11–12: preparing standard oxalic acid or Mohr's salt solutions for titration.
- B.Sc. analytical chemistry: making primary standards and serial dilutions.
- Water and soil testing: preparing calibration standards of known strength.
- 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 are separate items that can be quoted with it.
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.

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 is used for standard solutions. A conical flask carries only approximate graduations and is used for mixing and titrating.
Which sizes can I order?
The flask is listed in 50 ml, 100 ml and 500 ml. The 100 ml size suits most school standard solutions; the 500 ml size is useful for stock solutions.
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 you prepare.
Who supplies the Graduated Flask with Fixed Stoppers?
Science Lab Supplies supplies it from Ambala, India, and can quote it on its own or with the other volumetric glassware a chemistry lab needs.
Related Volumetric Glassware
Making a standard solution also calls for weighing, transferring and topping up to the mark. These four Chemistry Lab items support each of those steps and can be listed on one quotation with the volumetric flasks.
- Weighing Bottles — stoppered glass bottles for weighing the solute.
- Funnel — glass funnel for transferring solution into the neck.
- Calibrated Plastic Droppers — for adding the last drops up to the mark.
- Volume Measuring Cylinder — plastic cylinder for measuring solvent roughly.
