A 100ml reagent bottle with a screw cap, typically made of amber glass, is a specialized container used for storing light-sensitive chemical reagents or solutions. Here are the full details you might expect:

1. Material: Constructed from high-quality borosilicate glass tinted in amber color. Amber glass offers protection against light degradation, making it suitable for light-sensitive reagents.
2. Capacity: The bottle has a capacity of 100 milliliters, providing ample storage space for moderate quantities of liquid reagents.
3. Amber Color: The amber color of the glass provides protection against ultraviolet (UV) and visible light, minimizing photochemical reactions that could degrade light-sensitive reagents. This feature is crucial for preserving the integrity and stability of such reagents.
4. Screw Cap: Equipped with a screw cap closure, which ensures a tight seal to prevent leakage, evaporation, and contamination of the reagent. The screw cap design allows for easy opening and closing, facilitating convenient access to the contents.
5. Narrow Mouth: The bottle likely features a narrow mouth, which helps control the flow of the reagent during dispensing and reduces the risk of spills or splashes.
6. Graduated Markings: Some bottles may include graduated markings on the side, providing reference points for accurate measurement of the volume of liquid contained or dispensed.
7. Chemical Compatibility: Borosilicate glass construction ensures compatibility with a wide range of chemicals, while the amber color provides additional protection for light-sensitive reagents.
8. Manufacturer: The manufacturer or brand of the reagent bottle may vary depending on the supplier or distributor. Choosing a reputable brand ensures reliability and quality.
9. Usage: Reagent bottles with amber glass and screw caps are commonly used in laboratories, pharmaceutical industries, and chemical manufacturing plants for storing and dispensing light-sensitive reagents, such as certain pharmaceuticals, dyes, and solutions prone to photochemical degradation.

When using a 100ml reagent bottle with a screw cap and amber glass, always follow the manufacturer’s instructions for proper handling, storage, and disposal of chemicals to ensure safety and maintain the integrity of the reagents.
