Glass Volumetric Flask

The Glass Volumetric Flask is laboratory volumetric glassware used for preparing a liquid solution to a defined final volume. It is intended for schools, colleges, chemistry laboratories, analytical laboratories and research facilities that require controlled solution preparation, dilution and quantitative laboratory work.

Product Description

The STEMAids Glass Volumetric Flask is designed for laboratory procedures in which a solution must be made up to a specified volume. A volumetric flask typically has a bulb-shaped body, narrow neck and reference mark that allows the user to adjust the liquid level to the flask’s calibrated volume.

STEMAids specifies high-grade borosilicate glass across its laboratory glassware range. The exact capacity, tolerance class, calibration temperature, closure type and graduation specification of this flask should nevertheless be confirmed before procurement.

Key Features

• Designed for defined-volume preparation: Suitable for making solutions up to the flask’s specified calibration mark.
• Laboratory glass construction: Supplied as glass volumetric ware; STEMAids specifies borosilicate glass across its current glassware range.
• Narrow-neck format: Supports controlled adjustment of the liquid meniscus near the reference mark.
• Useful for quantitative work: Supports dilution, standard-solution preparation and chemistry practicals where final volume matters.
• Suitable for educational laboratories: Helps students learn correct meniscus reading and solution-preparation technique.
• Reusable laboratory vessel: Can support repeated laboratory use when cleaned, inspected and handled correctly.
• Procurement transparency: Capacity, tolerance class and calibration details should be confirmed for the exact supplied model.

How to Use the Glass Volumetric Flask

1. Confirm that the flask capacity and calibration specification match the procedure.
2. Inspect the flask for cracks, chips, contamination or damaged markings.
3. Add the required solute or transferred solution according to the laboratory method.
4. Add the appropriate solvent until the liquid level approaches the calibration mark.
5. Bring the flask to the required working conditions specified by the method.
6. Add solvent carefully until the correct point of the meniscus aligns with the calibration mark at eye level.
7. Fit the closure, if supplied, and mix the solution thoroughly using the prescribed technique.

Safety note: Wear appropriate laboratory PPE and inspect glassware before use. Do not use cracked or chipped flasks. A volumetric flask is intended for accurate volume preparation and should not be treated as general-purpose heating glassware unless the manufacturer specifically permits that use.

Care & Maintenance

• Rinse and clean the flask promptly after use with a method compatible with the chemicals handled.
• Avoid abrasive cleaning that could damage the calibration mark or glass surface.
• Store clean glassware securely to reduce impact, chipping and contamination.
• Remove any flask with cracks, damaged necks or illegible calibration markings from quantitative use.

Frequently Asked Questions

What is a Glass Volumetric Flask used for?

A Glass Volumetric Flask is used to prepare a solution to a defined final volume. It is commonly used for dilution, reagent preparation and quantitative chemistry procedures.

What material is the STEMAids volumetric flask made from?

The product is specified as a glass flask. STEMAids states that its current laboratory glassware range uses high-grade borosilicate glass, but the exact material specification for this flask should be confirmed before ordering.

What capacity is available?

The capacity of this exact product has not been verified. Confirm the required nominal volume before procurement.

Is this a Class A volumetric flask?

No tolerance class has been verified for this product. Do not assume Class A, Class B or a particular accuracy specification unless it is stated on the supplied product documentation.

Can a volumetric flask be heated directly?

A volumetric flask is primarily intended for accurate volume preparation, not routine direct heating. Follow the supplied glassware instructions and laboratory procedure rather than heating it as you would dedicated reaction glassware.

Can this flask be used in schools and colleges?

Yes. Volumetric flasks are suitable for supervised chemistry practicals involving solution preparation, dilution and volumetric measurement when the capacity and accuracy specification match the experiment.
