A fine mouthed reagent bottle is a glass container used in laboratories for short-term storage of liquid drugs, which has the function of reducing liquid evaporation and facilitating flow control. Mainly used for storing liquid reagents such as hydrochloric acid, phosphoric acid, sodium chloride solutions, etc. Its slender neck design can reduce the contact area between liquid and air, reduce volatilization losses, and facilitate flow control during pouring.
Features and Applications: The slim mouth design facilitates liquid pouring and effectively reduces reagent evaporation. There are transparent and brown colors, and white is generally used to store drugs that are not easily decomposed when exposed to light and heat, such as hydrochloric acid; Tea color is used to store easily decomposable drugs.
Material: There are two common types: glass and plastic. Glass material fine mouthed reagent bottles have good chemical stability and are resistant to chemical reagent corrosion. For example, borosilicate glass material reagent bottles are suitable for containing various chemical reagents. Plastic material fine mouthed reagent bottles, such as polypropylene (PP) material, have good chemical resistance, can be sterilized under high temperature and pressure, and the raw materials are non-toxic. They are commonly used in fields such as molecular biology and cell biology.
Specifications: There are various capacity specifications, including 60ml, 125ml, 250ml, 500ml, 1000ml, etc., which can meet the storage requirements of different experiments for reagents.
Precautions for use: When taking reagents, the bottle stopper should be placed upside down on the table, with the label facing the palm of the hand. After use, add a stopper and seal it if necessary. Due to the frosted inner side of the bottle mouth, it cannot hold strong alkaline reagents when paired with a frosted glass stopper. If alkaline reagents are to be held, a rubber stopper should be used instead to prevent strong alkalis from reacting with silicon dioxide in the glass, leading to adhesion between the bottle mouth and stopper.
Operating Specifications
Opening direction: Tilt the bottle body to open the lid, avoiding liquid splashing out; Immediately use after opening the lid to reduce exposure time.
Pouring technique: Use the inner edge of the bottle mouth to guide the liquid to flow out, preventing it from dripping onto the outer wall of the bottle.
Residual treatment: After pouring, wipe the bottle mouth with filter paper to prevent corrosion of the label or contamination of the reagent.
Cleaning and maintenance
Cleaning method: Immediately rinse with distilled water after use to avoid residual reagents corroding the bottle body; Stubborn stains can be soaked in dilute hydrochloric acid.
Drying treatment: After cleaning, invert and air dry, or wipe dry with a dust-free cloth to prevent water stains from remaining.
Regular inspection: Check the sealing of the bottle mouth, replace the worn-out frosted stopper in a timely manner to avoid air leakage.
