A 250ml clear reagent bottle is commonly used in laboratories for storing, handling, and dispensing various chemical reagents and solutions. Here is a full description along with key features of a 250ml clear reagent bottle:

Full Description:

The 250ml clear reagent bottle is a medium-sized, transparent container designed to hold chemical liquids. Made from high-quality materials such as glass or plastic, it ensures clarity for easy observation of the contents. This type of bottle is widely used in scientific, medical, and industrial laboratories for safely storing, mixing, and dispensing reagents.

Features:

1. Material:
   • Glass: Typically made from borosilicate glass due to its excellent chemical and thermal resistance. Borosilicate glass can handle temperature variations and resists chemical reactions, making it ideal for laboratory use.
   • Plastic: Commonly made from high-density polyethylene (HDPE) or polypropylene (PP), offering chemical resistance, durability, and being lighter than glass.
2. Capacity:
   • Holds up to 250 milliliters (ml) of liquid, suitable for medium-scale experiments and precise measurements.
3. Transparency:
   • The clear material allows for easy visual inspection of the contents, which is crucial for observing reactions, checking solution clarity, and verifying contents without opening the bottle.
4. Neck Design:
   • The bottle may feature a wide mouth or narrow neck. A wide mouth facilitates easier filling, pouring, and cleaning, while a narrow neck provides better control when dispensing liquids.
5. Cap:
   • Equipped with a screw-on or snap-on cap, usually made from plastic. The cap ensures an airtight seal to prevent contamination, evaporation, and spillage.
   • Some caps may have liners made of materials such as PTFE (Polytetrafluoroethylene) to enhance chemical resistance and prevent leakage.
6. Graduations:
   • Often marked with graduated scales on the side, allowing for approximate volume measurement of the contents. For precise measurements, it is recommended to use additional laboratory equipment such as graduated cylinders or pipettes.
7. Durability:
   • Designed to be robust and able to withstand frequent handling, cleaning, and various laboratory conditions.
8. Autoclavable:
   • Glass bottles and certain high-quality plastic bottles can be autoclaved, meaning they can be sterilized using high-pressure saturated steam at around 121°C, making them reusable and safe for storing sterile reagents.
9. Chemical Compatibility:
   • The bottle is compatible with a wide range of chemicals, making it versatile for different types of reagents including acids, bases, and organic solvents.

Applications:

• Laboratory Use: Suitable for storing chemical reagents, solutions, and samples.
• Medical Use: Used for holding various pharmaceutical preparations and solutions.
• Industrial Use: Ideal for storing and handling medium quantities of industrial chemicals.

Benefits:

• Visibility: Clear material allows for easy monitoring of the contents.
• Versatility: Suitable for a wide range of chemicals and solutions.
• Safety: Airtight caps prevent contamination and spillage.
• Durability: Robust construction for repeated use.

The 250ml clear reagent bottle is an essential tool in any laboratory, providing a reliable and safe solution for the storage and handling of chemical substances.
