Dosilab is a series of adjustable volume bottle top dispenser for dosing chemicals with precision, accuracy and inexpensiveness.

  • It is totally safe for operators and environment.
  • The six models of the line (0,25 ml to 100 ml) are simple to use and easy to disassemble to perform cleaning and maintenance operations; autoclavable without need for disassembly.
  • All the internal components that during use are in contact with liquid solutions are made of PTFE, FEP and borosilicate glass.
  • They therefore possess excellent compatibility with all reagents, except for hydrofluoric acid.
  • Volume adjustment is made precise and quick by using the adjustment knob, furtherly improved and supplied with internal and external locking system, to avoid accidental displacement during use.
  • Furthermore, the dispenser allows a 360 ° rotation when placed on the bottle.
