Product description Key benefits - Reliable cleaning for a wide range of laboratory glassware: designed specifically for flasks, Erlenmeyer vessels, reagent tubes and test tubes. - Practical storage and handling: hanging design on the lab glass brush allows easy wall mounting to keep workspaces tidy and brushes accessible. - Effective reach and surface contact: brush shapes and construction are optimized to clean inner walls and bottom areas that are hard to reach with standard cloths or sponges. - Durable, practical construction for repeated laboratory use. What each brush does - Lab glass brush (hanging design): hangs on the wall for easy storage and fast access during routine lab work; suitable for general glassware cleaning in daily lab use. - Pipe/rod cleaning brush: designed to clean the inner wall and the bottom of flasks and similar vessels; useful where thorough interior scrubbing is required. - Erlenmeyer brush: made from material suitable for practical laboratory use and shaped to match Erlenmeyer flask contours for effective cleaning. - Test tube cleaning brush: fine-detail design ensures thorough cleaning of test tubes and other narrow cylindrical glassware. Function, compatibility and performance - Function: removes residues and deposits from inside surfaces and bottoms of laboratory glassware where rinsing alone is insufficient. - Compatibility: intended for laboratory glassware including flasks, Erlenmeyer flasks, reagent tubes and test tubes. - Performance: engineered to provide consistent contact with curved and narrow surfaces to improve cleaning efficiency and reduce the need for repeated manual scrubbing. Typical use scenarios - Teaching or research labs: routine cleaning of glassware between experiments to maintain sample integrity and prevent cross-contamination. - Chemical preparation and analysis: thorough removal of residues from flask walls and bottoms before reuse or storage. - General laboratory maintenance: organized storage and reliable brush performance for daily glassware care. Practical notes - Store the lab glass brush on the wall-mounted hanger to save bench space and allow brushes to air-dry between uses. - Select the brush shape that matches the glassware being cleaned (pipe/rod brush for deep or wide-bottomed flasks, Erlenmeyer brush for conical flasks, test tube brush for narrow tubes) to maximize cleaning effectiveness.
