"GENIUS" Bottle top dispenser
Fully autoclavable with recirculation valve
Drawing quantities of liquids from large supply bottles is a daily routine in the lab.
This manual task must be carried out quickly, accurately, reproducibly, simply and safely.
GENIUS bottle-top dispensers is a family of instruments with proven precision that offer many advantages in routine liquid-handling operations.
GENIUS can be used in practically any operation and are suitable for organic and inorganic solutions.
Applications
- Salt solutions
- Acids
- Bases
- Many organic solvents
Components in contact with media
- Borosilicate glass, FEP, ETFE, PFA, PTFE, platinumiridium, PVDF (screw cap)
Operating limits
- Temperature: +15 °C to +40 °C
- Steam pressure: max. 500 mbar
- Viscosity: max. 500 mm2/s
- Density: max. 2.2 g/cm3
Features
- The materials that come in contact with media (PTFE, PFA, FEP, borosilicate glass and platinum-iridium) are resistant to most acids, bases, and solvents
- GENIUS is equipped with a positive displacement piston and a fluoroplastic (PFA) sealing lip on the cylinder wall
- The latter acts like a windscreen wiper to prevent crystal build-up on the cylinder wall from readily crystallisable media
- The glass cylinder is also coated with a plastic material that reduces the risk of splashes should breakage occur
- The telescopic filling tube can be adjusted smoothly to different bottle heights
- GENIUS is equipped with our patented recirculation valve (EP 542 241) that reduces reagent loss when ventilated
- The simple-to-use calibration function of the GENIUS helps to meet all of the requirements of testing-apparatus monitoring, with the minimum of downtime
- GENIUS is completely autoclavable at 121 °C (2 bar) according to DIN EN 285, and are DE-M marked
