Narrow Mouth Reagent Bottles

The narrow mouth reagent bottles are laboratory storage containers used for holding compatible chemicals, reagents, solutions and other laboratory materials. Their restricted neck opening supports controlled pouring and routine reagent storage, making them suitable for chemistry, analytical, educational and research laboratories where organized chemical storage and handling are required.

Product Description

The STEMAids Narrow Mouth Reagent Bottles are designed for routine laboratory storage and handling of compatible reagents and prepared solutions. A narrow-neck configuration provides a smaller opening than a wide-mouth bottle, helping users control liquid transfer and reducing the exposed opening during routine dispensing.

The exact bottle material, nominal capacity, colour, closure type, stopper or cap material, neck dimensions and chemical-resistance characteristics are . These properties must be checked against the current STEMAids specification before making compatibility, sterilization or light-protection claims.

Key Features

• Narrow-mouth design: Provides a restricted opening for controlled pouring and routine liquid handling.
• Reagent storage: Suitable for storing compatible laboratory chemicals, solutions and reagents.
• Reduced open area: The narrow neck limits the size of the exposed opening compared with a wide-mouth container during dispensing.
• Reusable laboratory format: May be cleaned and reused when permitted by the bottle material, contents and laboratory protocol.
• Organized laboratory storage: Supports labeling and segregation of prepared solutions and reagent stocks.
• Educational and professional use: Suitable for supervised school, college, analytical and research laboratory workflows.
• Material and closure specification: Exact bottle material and supplied closure are and should not be inferred from the product name.

How to Use the Narrow Mouth Reagent Bottles

1. Inspect the bottle and closure for cracks, chips, contamination or other damage.
2. Confirm that the bottle and closure materials are compatible with the reagent being stored.
3. Clean and dry the bottle according to the applicable laboratory procedure.
4. Transfer the reagent carefully using a suitable funnel or dispensing technique when necessary.
5. Leave appropriate headspace where required by the chemical or laboratory procedure.
6. Fit the supplied closure securely without applying excessive force.
7. Label the bottle with the contents, concentration, date and hazard information required by laboratory policy.

Safety note: Do not store an incompatible, pressure-generating or highly reactive material without verifying the bottle and closure specifications. Follow the chemical’s safety data sheet and your laboratory’s storage requirements.

Care & Maintenance

• Clean the bottle using a method compatible with both its material and previous contents.
• Inspect the neck and closure surfaces regularly for chips, wear or chemical residue.
• Store clean bottles dry and protected from impact.
• Do not reuse a reagent bottle for an incompatible chemical without appropriate decontamination.

Frequently Asked Questions

What are narrow mouth reagent bottles used for?

Narrow mouth reagent bottles are used to store and dispense compatible laboratory chemicals, prepared solutions and reagents. Their smaller opening supports controlled pouring during routine laboratory work.

Why use a narrow mouth reagent bottle instead of a wide mouth bottle?

A narrow-mouth bottle provides a smaller opening that is convenient for controlled liquid pouring. Wide-mouth bottles are generally easier to access when handling solids or materials that require a larger opening.

What material are the STEMAids reagent bottles made from?

The exact material is . Glass, borosilicate glass or another material should not be stated until verified from the current STEMAids specification.

Do these reagent bottles come with stoppers or screw caps?

The exact closure configuration is . The product should not be described as screw-cap or ground-stoppered until the supplied closure has been verified.

Can narrow mouth reagent bottles be used in schools and colleges?

Yes. They are suitable for supervised laboratory storage and chemistry practical work when the stored substance is compatible with the bottle and appropriate chemical-safety procedures are followed.
