With recirculation valve and calibration mechanism.

• Quick, easy and precise volume adjustment due to interior scalloped track and practical screw mechanism
• Innovative recirculation valve avoids reagent waste
• No drips after tube has been capped
• Easy calibration adjustment
• High-quality materials (PTFE, PFA, FEP, borosilicate glass, platinum-iridium) ensure good chemical resistance to most acids, solvents and bases
• A positive displacement plunger with PFA seal minimizes the crystallization of liquids and therefore the possibility of the plunger jamming
• Easy to dismantle for cleaning, no tools necessary
• Can be rotated 360° on bottle
• DE-M marked
• With screwable discharge valve

UV-absorbing, highly transparent.
For storage of light-sensitive substances.
With ring mark individually calibrated to In'.
Class A tolerances according to DIN EN ISO 1042.
With printed lot number and batch certificate. Thermal stress up to 121ºC (autoclaving) does not permanently exceed the tolerance limit. To preserve markings, do not clean at temperatures exceeding 60ºC...

With variable volume and calibration mechanism.

• Quick, easy and precise volume adjustment due to interior scalloped track and practical screw mechanism
• No drips after tube has been capped
• Easy calibration adjustment
• High-quality materials (PTFE, PFA, FEP, borosilicate glass, platinum-iridium) ensure high chemical resistance aganinst most acids, solvents and bases
• A positive displacement plunger with a PFA seal minimizes the crystallization of liquids and thus the clogging of the plunger
• Easy to dismantle for cleaning, no tools necessary
• Device can be rotated 360° on bottle
• DE-M marked
• With screwable discharge valve

Fixed volume and calibration mechanism. The screwable discharge valve is equipped with an additional safety bulb and closes the dosing channel, if dispensing tube is not installed, so that no medium can escape.

Scope of supply:
Bottle top dispenser, thread adapter GL 25, GL 28, GL 32, GL 38, S 40, telescopic filling tube, mounting tool, operation manual, quality certificate...
