Specially recommended for curved and cornered shaped labware such as round bottom flasks. Uniquely designed convex swiveling brush head gets contact with all over the surface of the flask including difficult curves and corners and enables thorough cleaning. The brush head has a slightly convex shape for fast and effective cleaning even also at heavy soiled flasks. Strong yet flexible bristles provide long lasting trouble free life cycle. Good grip due to the solid and long wooden handle. The swivel brush part fits through NS 29/32 or larger or any non tapered neck with a diameter 24 mm or larger. 360 mm lenght brush handle offers easy touch of the bottoms of larger size flasks.
