330mm Nylon S-Circle Brush
The 330mm Nylon S-Circle Brush from Eisco is an S-shaped nylon flask brush designed for cleaning the curved interiors of flasks, beakers, vases and other glassware. The semi-stiff nylon bristles and shaped head help you reach around rounded bases so you can remove residues that straight brushes often miss.
A semi-flexible twisted stainless steel handle allows you to adjust the angle slightly to suit different vessel shapes whilst maintaining good control. The nylon fibres provide effective scrubbing without scratching borosilicate glass or most plastics, making this brush suitable for routine washing in teaching, research and QC laboratories. The looped end gives you a convenient hanging point above sinks or wash stations, so the brush can drain and dry between uses. At approximately 330mm in total length, with a bristle section of about 160mm and 38mm diameter, it is well sized for common Conical (Erlenmeyer) flasks and similar glassware.
