Product Description

The Narrow-Mouth Amber Reagent Bottle is the standard container for light‑sensitive liquid reagent storage in laboratories, manufactured from soda‑lime glass (borosilicate glass 3.3 optional). The amber glass effectively blocks UV and visible light (290–500nm) to protect photolabile reagents from light‑induced degradation. The narrow mouth design reduces evaporation and contamination, while the ground glass stopper ensures a secure seal for long‑term reagent stability.

Key Features

Soda‑lime glass (standard): Good chemical stability, moderate thermal expansion coefficient — cost‑effective for routine laboratory use
Borosilicate glass 3.3 (optional): ISO 3585 compliant, extremely low thermal expansion (3.3×10⁻⁶/K), thermal shock resistant to 280°C — ideal for autoclaving and demanding applications
Amber light protection: Amber glass effectively blocks UV and visible light (290–500nm) to protect light‑sensitive reagents
Narrow mouth design: Smaller inner diameter reduces evaporation — ideal for long‑term liquid reagent storage
Ground glass stopper: Precision‑ground fit ensures an airtight seal, preventing evaporation and contamination
Chemical resistant: Excellent resistance to most acids, alkalis, and organic solvents

Quality Assurance

Every bottle undergoes rigorous dimensional inspection, seal integrity testing, and visual examination to meet the high standards required in professional laboratories.

Note: Standard configuration is soda‑lime glass. Borosilicate glass 3.3 is available upon request. When storing strong alkaline solutions, we recommend using a rubber stopper to prevent the glass stopper from seizing.

Applications

Typical Uses

Chemistry labs

Light‑sensitive reagents including silver nitrate, iodine solutions, and hydrogen peroxide

Pharmaceutical industry

Storage and dispensing of photolabile APIs and intermediates

Biology labs

Light‑sensitive buffers, media, and staining solutions

Analytical testing

Storage of light‑sensitive standards and standard materials

Educational labs

Light‑sensitive reagent storage for university and high school chemistry labs

Compatibility Recommendations

Bottle + Glass Stopper

Ideal for most light‑sensitive liquid reagent storage applications

Bottle + Rubber Stopper

Recommended for strong alkaline photolabile solutions to prevent glass stopper seizing

Bottle + Label

Use light‑sensitive labels with "Store in dark" or "Protect from light" warnings

Tip: Use amber and clear reagent bottles together to cover all your light‑sensitive and non‑sensitive reagent storage needs. For applications requiring higher thermal and chemical resistance, we recommend choosing borosilicate glass 3.3.

Operation & Maintenance

Amber Reagent Bottle User Guide

Before Use

Inspect for cracks, chips, or scratches before use
Ensure the bottle is clean and dry to prevent contamination of reagents
Verify that the stopper fits properly — no wobble or sticking
Select the appropriate stopper type (glass/rubber) based on your reagent

Light‑Sensitive Storage Procedure

Pour light‑sensitive reagent slowly down the inner wall to avoid splashing
Fill to no more than 80% capacity to allow for expansion and handling
Gently rotate the stopper to ensure a snug, secure seal
Wipe the exterior clean and apply a light‑sensitive label (name, concentration, date, "Protect from light")
Store in a cool, dry, well‑ventilated area away from direct sunlight
The amber glass itself provides light protection — no additional wrapping required

Cleaning & Maintenance

Clean promptly after use to prevent residue from hardening
For routine cleaning, use detergent with a bottle brush, rinse 3× with distilled water
For stubborn residues, soak in dilute acid or specialty cleaning solution
Allow to air‑dry inverted on a draining rack
For long‑term storage, place a small piece of paper between the stopper and the neck to prevent seizing

Care & Notes

Safety Notice

Always inspect for cracks or damage before use — damaged bottles may break during use
For strong alkaline solutions, use rubber stoppers to prevent glass‑to‑glass seizing
For hydrofluoric acid and other specialty reagents, confirm material compatibility before use

Do not

Do not place reagent bottles directly on hot plates or open flames
Handle with care — avoid impact and rough handling
