GL80 Screw Thread Closures

A low coefficient of thermal expansion (3.3), provides temperature resistance that is far superior to that of standard lab glass (or soda lime glass). Aijiren glass can withstand temperatures from -70 to 500°C, permitting repeated use in freezers, microwaves, autoclaves and dry heat sterilization chambers.

Constructed from plastic, glass, borosilicate glass or soda-lime glass, reagent bottles feature stoppers or caps, which protect the contents from spilling or outside environmental contamination. Reagent bottles are excellent for storing powders and liquids. Reagent bottles in tinted amber or red protect light-sensitive contents from UV light, visible light and infrared radiation. Reagent bottles are available with narrow mouths for better control while pouring, or wide mouths for easy filling or content retrieval. Caps and stoppers for reagent bottles should be selected carefully, as their material or lining may interact negatively with the contents of the bottle.

The reagent bottles are made of durable materials, such as borosilicate glass, offering excellent chemical resistance and long-term durability. The clear glass construction allows for easy visibility and monitoring of the reagent level. The GL45 screw cap provides convenient sealing and unsealing of the bottle, facilitating easy access to the reagent.

Reagent bottles are made of borosilicate glass or soda lime glass with stoppers or caps to prevent spillage of contents or contamination from external environments. Reagent bottles are ideal for storing powders and liquids. Amber or red reagent bottles protect the photosensitive contents from UV, visible and infrared radiation.

COD reagent vial refers to a specific type of vial used in chemical analysis for measuring the chemical oxygen demand (COD) of a water sample. COD is a measure of the amount of oxygen required to chemically oxidize the organic and inorganic compounds present in a water sample.
The COD reagent vial contains the necessary chemicals and reagents to facilitate the oxidation reaction. It typically includes a mixture of strong oxidizing agents, such as potassium dichromate or potassium permanganate, along with other chemicals that help initiate and accelerate the oxidation process.

1. Made of premium glass, high quality, durable
2. High hardness, transparent, clear scales,
3. Designed with improved handling and more efficient storage of biologicals and other aqueous solutions
4. Wide mouth opening allows for quick fill, commonly used as lab bottles, jars in laboratory, and home uses

Reagent bottles, also known as media bottles or graduated bottles, are containers made of glass, plastic, borosilicate or related substances, and topped by special caps or stoppers. They are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves.

Some reagent bottles are tinted amber (actinic), brown or red to protect light-sensitive chemical compounds from visible light, ultraviolet and infrared radiation which may alter them; The bottles are called “graduated” when they have marks on the sides indicating the approximate (often with a 10% error) amount of liquid at a given level within the container. A reagent bottle is a type of laboratory glassware.?
