Dispenser

Product description
The high quality DURAN Group Dispenser and the new DURAN Group Dispenser PRO make it easier and safer to dispense liquids directly from DURAN laboratory glass bottles. They offer the highest levels of precision in line with DIN EN ISO 8655 and ensure optimum reproducibility. The return valve on the DURAN Group Dispenser PRO also allows priming to take place without any loss of media. The threads of the DURAN Group Dispenser and DURAN Group Dispenser PRO are perfectly matched to the GL 45 thread on DURAN laboratory glass bottles, guaranteeing the best possible seal and reducing media loss. The easy action cylinder can be operated with just one hand, allowing effortless serial dispensing Additional benefits include safe storage of the content and protection against escaping vapours. The discharge tubes can be sealed with a cap. The dispensers are compatible with other thread sizes using the adapters (GL 28, GL 32, GL 38, S 40) supplied. In addition to borosilicate glass 3.3, the media only comes into contact with high quality plastics such as PTFE, PFA, ETFE, FEP and a platinum iridium compound. The DURAN Group Dispenser is therefore resistant to the majority of acids, bases and solvents, which combined with its virtually wear free properties makes it a universal solution. The PFA sealing lip around the cylinder wall prevents crystallisation in the media, even media that crystallises very easily, thus preventing the piston from becoming stuck.
