Mill-Rose Volumetric Flask Brush Pack. Combining top-notch and uncompromising quality with an affordable price the Mill-Rose Volumetric Flask Brush 72132W/ 70230-010 can fulfill your laboratory needs while still offering a great value for the money. Product Category Description: Dusting or cleaning a wide-mouth glassware container can be difficult because of the unusual shape of the flasks used. For a long time standard cotton swabs and cotton dusters were the best tools for the job. We developed a molded polystyrene brush with a sturdy base to fit the shape of a wide-mouth flask. To use the brush hold the flask with the brush end firmly in your hand while you clean. Dampen the brush by striking it on a solid surface with the back of your hand. A thorough cleaning will restore the spout to its normal shape and then the flask can be tumbled with a string or scouring pads to remove any residue. Styrene styrene neck caliber allows the flask to be blown dry with an etch of acid or alkali metal leaving no residue.
