Product Code : SCL-GW-12012
The Conical Flask 50mL with Glass Stopper is a laboratory glass flask used for mixing, swirling, holding, and short-term storage of liquid samples. It is suitable for school laboratories, college chemistry labs, research facilities, and routine laboratory users who need compact glassware with a stopper for controlled sample handling.
Product Description
The Glass conical 0050mL glass stopper from Scientific Equipment is a 50mL conical flask designed for small-volume laboratory work. Its conical body supports smooth swirling, while the glass stopper helps cover the contents during short-term holding or controlled handling.
This flask is useful in chemistry practicals, reagent preparation, solution mixing, sample storage, and classroom demonstrations. The narrow neck helps reduce splashing during swirling, and the transparent glass body allows users to observe liquid level, colour change, precipitation, and reaction behaviour during experiments.
Key Features
- 50mL capacity: suitable for small-volume liquid handling, preparation, and storage.
- Glass stopper included: helps cover the flask opening during short-term laboratory use.
- Conical flask design: supports safer swirling and mixing compared with open vessels.
- Narrow neck: helps limit splashing while handling liquids.
- Transparent glass body: allows clear observation of sample level and reaction changes.
- Reusable format: suitable for repeated use when cleaned and stored correctly.
- Classroom-ready size: practical for school, college, and training laboratory benches.

How to Use the Conical Flask 50mL with Glass Stopper
- Inspect the flask and stopper for cracks, chips, stains, or residue before use.
- Rinse the flask with clean water or the required solvent according to the laboratory method.
- Add the required liquid sample without exceeding the safe working volume.
- Hold the flask near the neck or upper body and swirl gently to mix the contents.
- Insert the glass stopper only when covering the sample is required and the contents are compatible.
- Do not stopper a flask during heating or gas-forming reactions unless the procedure is specifically designed for that setup.
- After use, remove the stopper carefully, empty the flask safely, wash, rinse, and dry both parts before storage.
Safety note: Wear eye protection and gloves when handling chemicals. Do not heat a closed stoppered flask, as pressure buildup can cause breakage or sample release.
Care & Maintenance
- Clean the flask and stopper after every use to prevent residue buildup and cross-contamination.
- Store the stopper with the matching flask to avoid fit issues.
- Avoid sudden temperature changes unless the verified glass type supports thermal shock resistance.
- Remove the flask from service if the neck, rim, body, or stopper is chipped or cracked.

Frequently Asked Questions
What is a Conical Flask 50mL with Glass Stopper used for?
A Conical Flask 50mL with Glass Stopper is used for mixing, swirling, holding, and short-term covering of small liquid samples in laboratory work.
Why does this conical flask include a glass stopper?
The glass stopper helps cover the flask opening during short-term sample handling or storage. It should not be used to seal reactions that generate heat, vapour, or gas unless the method specifically allows it.
Is this flask suitable for school chemistry labs?
Yes. It is suitable for supervised school, college, and university chemistry practicals involving small-volume liquid handling.
What material is the flask made from?
The product name confirms glass construction. The exact glass type, such as soda-lime glass or borosilicate glass, should be confirmed before publishing.
Can the flask be heated with the stopper fitted?
No. A stoppered flask should not be heated unless a validated laboratory procedure specifically requires it. Heating a closed flask can create internal pressure.
Does this product include only the flask?
No. Based on the product name, the item includes a 50mL glass conical flask and a glass stopper. Confirm pack quantity before publishing.
