A high intensity pulse Light cure units for the curing of Medical Device grade 3D Printed materials using Nitrogen. Otoflash G171: Flash-curing device for light-curing.....This unit has the additional ability to flush the chamber with Nitrogen gas for curing in an inert environment. Supplied with the connectors & regulator (NOT N2 GAS - which must be obtained locally) The Otoflash G171 has two flashbulbs that emit light into the polymerisation chamber from below. It is therefore especially suitable for application in otoplastics/hearing aids and in the production of jewellery. The device can be used for the photopolymerisation of all light-curable materials where the curing takes place at a wavelength of 280-700 nm.
