Product Description

The Amber Dropping Bottle is the professional tool for precision dispensing of light‑sensitive liquid reagents 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 inner surface of the bottle neck is precision‑ground to form a tight seal with the matching dropper, ensuring sealing integrity and precise control during dispensing. Select models offer a rubber bulb option for more flexible dispensing control. It is an essential tool for precision photolabile reagent dispensing in chemistry, pharmaceutical, and biology laboratories.

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
Ground dropper: Precision‑ground fit ensures a tight seal and precise drop control
Rubber bulb optional: Select models available with rubber bulb for flexible dispensing control
Multiple capacities: Available in 15mL, 30mL, 60mL, 125mL, 250mL, 500mL, and 1000mL

Quality Assurance

Every unit undergoes rigorous dimensional inspection, fit testing, and visual examination to ensure smooth, precise dispensing performance.

Note: Standard configuration is soda‑lime glass. Borosilicate glass 3.3 is available upon request. Amber Dropping Bottles are designed for light‑sensitive liquid reagent dispensing. The dropper and bottle are manufactured as a matched set — do not interchange with other brands. Please specify if you require the rubber bulb configuration when ordering.

Applications

Typical Uses

Chemistry labs

Precision dispensing of light‑sensitive indicators, color reagents, and standard solutions

Biology labs

Drop‑by‑drop addition of light‑sensitive stains and media supplements

Pharmaceutical industry

Precision addition of light‑sensitive micro‑quantities of reagents

Analytical testing

Precision dispensing of light‑sensitive standards and standard materials

Educational labs

Light‑sensitive reagent dispensing in chemistry and biology teaching

Compatibility Recommendations

Amber Bottle + Ground Dropper

Standard configuration for precision dispensing of light‑sensitive reagents

Amber Bottle + Rubber Bulb

Optional configuration for flexible dispensing control with light protection

Amber Bottle + Light‑Sensitive Label

Use labels with "Protect from light" warnings

Tip: Use amber and clear dropping bottles together to cover all your light‑sensitive and non‑sensitive dispensing needs. The rubber bulb option provides more flexible control, especially for experiments requiring precise drop‑by‑drop dispensing. For applications requiring higher thermal and chemical resistance, we recommend choosing borosilicate glass 3.3.
