Abstract
Thin tubelets coated on their inner wall with a solid coating of a dyestuff or staining reagent are used to stain biological material by passing such material through the tubelet, optionally after mixing with a solvent, and allowing the biological material to react in the tubelet with the dyestuff or staining reagent.
