Square, Wide-Mouth Reagent Bottle, Graduated, GL80

The Square, Wide-Mouth Reagent Bottle (GL80) from Osmosis Scientific redefines laboratory storage by combining the chemical purity of Borosilicate 3.3 glass with a highly functional physical design. The standout feature is the 80mm wide-mouth opening, which is significantly larger than standard GL45 bottles. This allows for effortless filling and emptying of powders, granules, and high-viscosity liquids, and even enables the use of large spatulas or overhead stirrers directly inside the bottle.

The square footprint is engineered for laboratories where space is at a premium. These bottles can be packed tightly together on shelves, in refrigerators, or in autoclaves, minimizing “dead space” and improving organizational efficiency. Despite the square exterior, the interior corners are smoothly radiused to ensure easy cleaning and total sample recovery.
