The right tool for the right job! Test Tube Brushes seem to be one of those items you don’t really think about until you need it. I recently received orders from several labs. In each case, the tech ran out or had used the last remaining brush they had, beyond the life of the bristle. Needless to say, I end up placing some rush orders, which prompted me to create this blog as a friendly reminder to those of you who haven’t checked your stock of brushes in a while.
Standard lengths range from 8″ to 13″ with brush diameters from 3/4″ (1.9 cm) to 1-3/8″ (3.5 cm). Though there are longer and wider brushes available, including beaker and centrifuge brushes, which I’ll address in a future blog. Choice of bristle’s are nylon and natural and most come in packs of 10, which should keep you going for awhile.
Again, these brushes are ideal for cleaning test tubes and narrow mouth glassware. Rounded tuft at tip facilitates cleaning and protects the glassware.
The brush pictured to the right is an example of a test tube brush that has a Tufted End.
