A 1000ml Reagent Bottle with a Narrow Mouth (N/M) is a standard laboratory storage container designed for the secure handling and precise dispensing of liquid reagents. The “N/M” designation specifically refers to the narrow mouth, which is typically about one-third the width of the bottle body to minimize spills and reduce the volatilization of stored liquids.
Core Specifications
- Capacity: 1000 ml (1 Liter).
- Materials:
- Plastic (Polypropylene/HDPE): Rigid, translucent, and highly chemical-resistant. Often autoclavable.
- Glass (Borosilicate/Soda-lime): Superior thermal shock resistance and chemical purity. Brands like Pyrex or Borosil use borosilicate 3.3 for high-temperature and aggressive chemical applications.
- Closure Types:
- Screw Caps: Typically made of polypropylene (PP) with a built-in seal ring for a leak-proof closure.
- Glass Stoppers: Ground glass joints (often size 29/32 for 1000ml) provide an airtight seal, ideal for volatile or hygroscopic substances.
- Color Variations:
- Clear/Transparent: Best for monitoring liquid levels and identifying contents.
- Amber: Designed to protect light-sensitive chemicals from UV and visible light radiation.
- Dimensions: Approximately 235 mm in height (with stopper) and 107 mm in outer diameter.
Common Applications
- Liquid Storage: Ideal for acids, bases, organic solvents, and prepared chemical solutions.
- Precise Dispensing: The narrow neck allows for controlled pouring into smaller vessels.
- Environments: Extensively used in research labs, educational institutions, and industrial testing facilities.
