High Durability Sapphire Prism
All Rudolph Research J-Series instrument offer a sapphire prism for high mechanical and chemical durability. The sample well is acid resistant 316 stainless steel with a Techtron sealing ring. There is no lamp to change, the LED light source is guaranteed for 1,000,000 measurements.
Shallow Refractometer Sample Well – All Rudolph J-Series Models
Refractometer measurement accuracy is only as reliable as the cleanliness of the sample well. Hard to clean sample wells can lead to inaccuracies due to residual from a prior measurement. Rudolph Research set out to dramatically minimize this problem by taking a new approach to sample well design. The Rudolph sample well is very shallow and smooth allowing easier cleaning and less surface area for contaminates to hide. Less sample is required and the well cleans easily. The result is more accurate measurements due to significantly less opportunity for sample contamination.
Refractometer – Sample Temperature Control
Rudolph’s uniquely designed refractometer sample well and electronic heating and cooling system improves results. For many applications sample temperatures must be accurately controlled within the sample well. When an application requires highly controlled temperature, a temperature controlled presser will assure even and highly accurate temperature stability. A sample in the measurement well that is controlled from both the top and bottom affords the most accurate measurement at a required temperature.
