Smart Measure™ Calibration Reference Materials The J257 and J357 model Series know when a sample is loaded on CRM’s are available at various RI indexes and the prism and will read automatically. The instrument will not read Temperatures. Contact a customer service representative if the prism is not cleaned properly. for assistance in choosing a calibration standard that is right for your your application. TempTrol™ Exclusive Dual Temperature Control System with cooling and heating above and below the sample allows the J357-CC models unparalleled temperature stability and range: ±0.01°C from 5°C- 100°C. 5 Decimal Place Accuracy over the complete RI Range: Some brands offer a wide RI Range and some offer 5 decimal place accuracy, but only Rudolph’s J357-CC provides 0.00002 RI accuracy Insulating Ring over a range of 1.26 to 1.72 RI.

Your instrument’s interface can be customized to meet the information your application and environment demand whether you choose our full featured interface or our Load-and-Go™ display interface. The J257 and J357 offer laboratory flexibility with industrial strength and simplicity making this model series at home on the laboratory bench or on the factory floor. Full Display with Smart Measure™ Load - and - Go™ Display Trend Analysis™ Display In a modern factory, the most precious commodity is time. When a process starts to move outside its limits people want to know FAST. They want to correct the problem, preferably while it’s still small and before a product goes out of specification. The Rudolph live reading and Trend Analysis™ feature allows users to easily and quickly see how a process is going and catch minor deviations before they become major ones. Even in the most tightly controlled manufacturing environments, things do occasionally go out of specification. When an out of specification condition happens, material has to be quickly identified and decisions made as to what to do with the product. Long term data collection is a part of any good process. Knowing when and where the out of specification condition happened is equally as important. Rudolph Trend Analysis™ software quickly shows a supervisor the process history and where the problem occurred.

The (CC)Sample Cover is controlled to the same temperature as the prism and, when lowered, is Concave (CC) Sample Cover designed to provide a temperature controlled micro environment that provides unrivaled temperature stability, fast measurement time and minimal Sample Shallow evaporation. sample Optional Contact Presser (CP Option) well Temperature The J257 and J357 are available with an optional controlled prism Temperature Controlled Sample Presser (CP option) that touches the sample. Compared with the standard temperature controlled cover, the optional Contact (CP) (CP) Contact Presser reduces the empty volume of the Sample Presser measurement area thereby decreasing evaporation and at the same time helping to evenly spread semi solid materials over the measurement Sample Shallow prism. This feature offers improved sample performance on many samples such as wel PET and Glycerine.

Designation: D 1747-99 Standard Test Method for Refractive Index of Viscous Materials 1. Scope 1.1 This test method covers the measurement of refractive indexes, accurate to two units in the fourth decimal place, of transparent and light-colored viscous hydrocarbon liquids and melted solids which have refractive indexes in the range between 1.33 and 1.60, and at temperatures from 80 to 100°C. Temperatures lower than 80°C can be used provided that the melting point of the sample is at least 10°C below the test temperature.

Many of these pharmacopeias require the Fluoromethyl 2,2,2-trifluoro-1-(trifluoromethyl)ethyl ether measurement of refractive index. For example, the US Pharmacopeia [ 28523-86-6]. requires that sevoflurane has a refractive index of 1.2745 - 1.2760 at 20°C.
