Flat-Bottomed Flasks 250ml
Product Code : SCL-CL-11508
Flat-Bottomed Flasks 250ml (SKU SCL-CL-11508) are 250 ml transparent glass flasks with a spherical body, a flat base and a long neck. The larger volume makes them a general-purpose vessel for boiling water, preparing reagent solutions and culture media, and running gas-generation experiments on school and college benches. Science Lab Supplies ships them from Ambala, India, for schools, colleges, training institutes, tender contractors and distributors, as part of its laboratory glassware range.
Specifications
Each flask has a 250 ml spherical body with a flat bottom and a long mouth (neck). The transparent glass is listed as chemical resistant and heat resistant. The flat base keeps the filled flask steady on the bench or on gauze, and the long neck reduces splashing and takes a stopper or cotton plug.

Applications and Experiments for the Flat-Bottomed Flask 250 ml
The 250 ml flat-bottomed flask handles medium volumes that need heating or mixing without a clamp. It suits NCERT Class 9–10 science, Class 11–12 chemistry, B.Sc. microbiology media preparation, and technician courses in which students make up and store laboratory solutions.
- Class 9–10 science: boiling water and generating gases with a stopper and delivery tube.
- Class 11–12 chemistry: dissolving solids and heating solutions before filtration.
- B.Sc. microbiology: preparing broth or agar before sterilisation, closed with a cotton plug.
- Laboratory technician courses: making up and holding stock solutions.
Leave the neck open or loosely plugged whenever the flask is heated, and allow hot liquids to cool before handling the flask by the neck.
