Abbe Refractometer DR-A1-Plus

This model features a brighter field of view than its predecessor, the DR-A1, making it easier to measure inhomogeneous and/or dark samples. The operations and specifications are the same as the DR-A1. Please contact ATAGO for recommendations on which of the 2 models is better-suited for your sample type.
