Flask, Conical, Wide Neck Manufacturer,Supplier and Exporter in India

Flask, Conical, Wide Neck (Product Code: SLE/GFL/17) is a clear 250 ml Erlenmeyer flask in borosilicate glass with a wide neck and white graduations, made to Class B. The sloping conical sides let contents be swirled without spilling, and the broader mouth speeds up filling, pouring and cleaning. It is a versatile conical flask for school, college and testing laboratories, manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

In titration practicals the wide neck makes it easy to position the flask under a burette tip and to rinse the walls down with a wash bottle as the end point approaches, while the conical shape lets students swirl vigorously without losing liquid. The same flask is used for dissolving solids — powders pour straight in through the broad mouth — for warming solutions on a hot plate with magnetic stirring, and for collecting filtrate beneath a funnel.

The clear glass gives an unobstructed view of colour changes, and the white graduations stand out against most coloured solutions for a quick volume estimate. Heat it gradually, avoid setting a hot flask on a cold or wet surface, and clean it with a brush and laboratory detergent — the wide neck lets the brush reach the base easily.

Frequently Asked Questions

What does Class B mean for this flask?
Class B is the general laboratory grade of glassware tolerance, as distinct from the tighter Class A used for volumetric glassware. Graduations on a conical flask indicate approximate volume, so use a pipette, burette or volumetric flask when precise volumes are needed.

What capacity is it?
This wide-neck conical flask is listed in 250 ml. For other capacities, see our standard conical flasks or contact us.

Why choose a wide neck instead of a standard neck?
The wider mouth takes powders and larger funnels more easily, is quicker to fill and pour, and is simpler to clean thoroughly.

Can it be heated on a hot plate?
Yes, the borosilicate glass is heat resistant. Warm it gradually and avoid heating the flask while it is empty.

Is a calibration certificate available?
Please contact us to discuss documentation requirements before placing your order.

Can you supply class sets or export orders?
Yes. Send the quantity and delivery destination in India or abroad, and we will quote pricing and dispatch time.
