Reagent Bottles, Narrow Mouth (Printed Graduation)

Quick answer: Narrow Mouth Reagent Bottles with printed graduation markings are borosilicate glass bottles used to store and measure liquid reagents accurately, with a narrow opening that reduces evaporation and spillage compared with a wide-mouth bottle. Reagent Bottles, Narrow Mouth (Printed Graduation) is priced at approximately ₹530 (indicative market benchmark, incl. GST, August 2026).

Narrow Mouth Reagent Bottles are the standard choice for storing liquid reagents where controlled pouring and minimal evaporation matter more than easy access to the contents — the narrow neck naturally reduces spillage during pouring and limits the surface area exposed to air, helping preserve volatile or air-sensitive reagents for longer. The permanent printed graduation markings let students check the approximate volume remaining at a glance without needing a separate measuring vessel, useful for keeping track of stock levels during a busy practical session. Made from chemically-resistant borosilicate glass, these bottles are built to safely contain volatile or corrosive liquids over repeated use in a school, college or research chemistry laboratory.

Technical Specifications

Applications

• Long-term storage of volatile or air-sensitive liquid reagents
• Controlled pouring and dispensing during reagent preparation
• At-a-glance stock-level checks via printed graduation markings
• General reagent storage for chemistry laboratory stockrooms

Care & Maintenance

• Handle with care, as borosilicate glass, while durable, can still break if dropped or knocked
• Clean and dry thoroughly between different reagents to avoid contamination
• Store with a compatible stopper or cap firmly in place to limit evaporation and contamination

Frequently Asked Questions

Why choose a narrow mouth bottle over a wide mouth one?

A narrow mouth reduces spillage during pouring and limits the surface area exposed to air, which helps reduce evaporation of volatile reagents compared with a wide-mouth bottle.

How accurate are the printed graduation markings?

They are intended for at-a-glance approximate volume checks rather than precise measurement; for accurate volume work, use a dedicated measuring vessel such as a graduated cylinder — exact graduation accuracy has not been independently verified for this listing.

Is this bottle suitable for corrosive chemicals?

Borosilicate glass is generally chemically resistant and suited to a wide range of laboratory chemicals, but compatibility with specific highly corrosive reagents should be confirmed with STEMAids before use.

Does STEMAids supply this in bulk for institutional labs?

Yes — STEMAids supplies laboratory glassware including reagent bottles for institutional and bulk orders; contact STEMAids to confirm current quantities and pricing.

Are exact bottle capacity and dimensions available for tender specification?

Exact capacity and dimensions have not been independently verified for this listing. Institutions preparing tender documents should confirm precise specifications directly with STEMAids before finalising procurement paperwork.

Is STEMAids a registered manufacturer of this product?

Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
