Conical Flask With Joint
Conical Flask With Joint (Product Code: SLE/GFL/03) is a graduated borosilicate conical flask whose neck is formed as a joint, so it can be closed or connected to matching jointed glassware instead of relying on a loose stopper. Heat resistant and chemical resistant, it is ideal for mixing liquids and is used in college, university and research chemistry laboratories that assemble jointed apparatus. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory glassware manufacturer and chemistry lab instruments supplier to India and international markets.

Typical Use
The flat base and conical body make this flask stable on the bench and easy to swirl, which is why it is favoured for mixing liquids and dissolving solids. On a hot plate magnetic stirrer the conical shape keeps a stirring bar centred while the joint at the neck lets the flask be closed with a matching stopper or linked to other jointed items — for example a condenser for gentle reflux or an adapter in a small assembly — provided the joint sizes match.
Keep ground joints clean and free of solid particles before assembly, as grit can prevent a good seal or cause the parts to stick. Separate joints after use rather than leaving them assembled, and rinse the flask promptly so residues do not dry in the joint.
Manufacturer
The flask is made by Jain Scientific Equipments Private Limited, an Ambala, Haryana company that trades under the ScienceLab brand and serves teaching and research laboratories. For an overview of its activities and product families, please see our company profile.
Related Laboratory Equipment
Equipment commonly used with a jointed conical flask:
- Magnetic Stirrer With Hot Plate — for stirring and warming liquids in the flask
- Liebig Condenser — a condenser for jointed set-ups; check the joint size matches
- Round Bottom Flask — the usual choice when heating in a mantle or under strong reflux
- Conical Flask — the plain-neck version for everyday titration and mixing

Frequently Asked Questions
What joint size does the flask have?
The joint size is not given in our current listing. Please contact us with the size you need so we can confirm availability.
Which capacities are available?
Capacities are not listed on this page. Tell us the volume you want in your enquiry and we will confirm.
Is a stopper included?
A stopper is not listed as included. Ask for a matching stopper when you enquire if you need one.
Can it be heated?
Yes, the borosilicate glass is heat resistant. Heat gradually and, for vigorous boiling under reflux, a round bottom flask is often the better choice.
How do I stop the joint from sticking?
Keep the joint surfaces clean, do not leave items assembled for long periods, and separate them while the glass is at room temperature.
Do you supply universities and distributors in quantity?
Yes, we supply institutions and distributors across India and international markets.
