Duplex II Hemicylinder Replacement
duplex ll hemicylinder

Our GemPro refractometer has a hemicylinder that is exactly like the one used in GIA's Duplex II except we use a superior glass. We use german Schott glass that doesn't scratch easily and doesn't tarnish or get messed up from the RI fluids. For this reason we have for decades replaced the hemicylinders in duplex II refractometers. Customers can't believe the difference when they get their instruments back. This is the last hemicylinder change you'll ever need!
