Autoclavable at 121 °C with adjustable volume.

• Direct displacement plungers with a fluoroplastic (PFA) seal that works like a windscreen wiper to prevent build-up of easily crystallizing media on the cylinder wall
• Glass cylinder coated with a synthetic material that reduces risk of splashes if breakage should occur
• Telescopic intake tube can easily be smoothly adjusted to the height of the bottle

The genius² bottle top dispensers are precision devices that offer many advantages. Since the materials in contact with the media (PTFE, PFA, FEP, borosilicate glass and platinum-iridium) are resistant to acids, solvents and bases, they can be applied almost universally. They are equipped with a patented recirculation valve that reduces reagent loss when ventilated. The simple-to-use calibration function helps to meet all of the requirements of testing-apparatus monitoring, with the minimum of downtime.
