Select a Refractometer for your demanding Laboratory application from the wide range of instruments available from Rudolph Research. Rudolph is a leading analytical laboratory instrument supplier, manufacturing precision quality benchtop instruments for the Pharmaceutical, Chemical, Petroleum, Petro-Chemical, Food, and Beverage industries.
All Rudolph instruments are designed to meet specific application requirements of specific industries and all are designed to exceed your requirements. A range of models and numerous configurations are available.
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.
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 contaminants 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.
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.
Rudolph understands your measurement applications and provides the needed instruments and configurations to meet your requirements. Application requirements may be dictated by regulatory agencies, quality control demands, or sample handling concerns. Refractometers may also be utilized in conjunction with other instruments for multiple measurements – load one sample to receive multiple measurement results. Sample delivery may also automated with or without other instruments for a complete laboratory automation solution designed to increase efficiency in your laboratory.
Rudolph Research Analytical offers a comprehensive range of Preventive Maintenance and Service Programs. Rudolph has demonstrated a commitment to its customers by keeping installed instruments operational, not only for 20 years, but in some cases for over 40 years.
This long-term commitment to keeping Rudolph instruments running makes the cost of ownership, over the life of a Rudolph Instrument, one of the lowest in the laboratory market segment. At the date this document was published, there is no other laboratory instrument manufacturer guaranteeing service and technical support for 20 years.
