Kartell DOSILab adjustable-volume bottle-top dispensers

DOSILab is a series of six adjustable-volume bottle-top dispensers from Kartell, designed for dispensing chemicals with precision and accuracy. Using the analog slider, the volume of each dose can be adjusted. The range has a capacity of 0.25-100 mL and a subdivision of 0.05-2 mL.

Each dispenser features a PTFE piston with silicone O-ring to ensure a high degree of accuracy. The internal cylinder is formed from borosilicate glass and protected by a polypropylene sheath for a long working life. The valve housing is a single piece, made from PTFE for high chemical resistance. As such, the performance of the range is good with all reagents (including organic solvents and concentrated acids) except hydrofluoric acid.

Every appliance in the range is individually calibrated according to ISO 8655 standards and is supplied with its own calibration certificate. Using the supplied tool, each device can be recalibrated, conforming to the requirements of the GLO/ISO standards. Each dispenser is also supplied with five adaptors for use with the most common reagent bottles: 28, 32, 36, 40 and 45 mm.

The models can be easily disassembled for cleaning and maintenance. They can also be autoclaved at 121°C without being disassembled.
