Amber graduated bottle with ISO GL80 thread borosilicate 3.3

Laboratory bottle in amber borosilicate 3.3 glass. The amber colouring protects contents against UV radiation — essential for photosensitive reagents that degrade on exposure to light. GL 80 thread to ISO 4796 with drip-free ring and blue polypropylene cap supplied.

Features

• Material: Amber borosilicate 3.3 glass
• Thread: GL 80, to ISO 4796
• Cap: Blue polypropylene, included
• Seal: Drip-free ring included
• Autoclave: Yes, up to 134 °C

Applications

Storage and dispensing of photosensitive reagents, organic solvents and biological solutions. The wide GL 80 mouth allows filling and emptying with pipettes or measuring cylinders — no additional adaptors required. Routinely used in microbiology, analytical chemistry and pharmaceutical settings.

Graduations allow visual volume estimation directly in the bottle, without transferring to a separate vessel for measurement.

Closure details

The drip-free ring ensures no leakage if the bottle is tipped over — relevant when storing flammable or corrosive solvents. PP cap resists most dilute acids, bases and polar solvents. ISO standardised thread: compatible with GL 80 caps and accessories from other manufacturers.
