Food and Beverage Refractometer
The Rudolph Research Analytical J47 benchtop refractometer is designed to meet the unique needs of a food and beverage testing where the samples are mostly a mixture of sugar and water. The J47’s single flat measurement surface, temperature correction and one button measurement capability make it perfect for heavy use applications. The J47 corrects for errors caused by sample temperature variation. Temperature correction is a very fast mathematical solution to obtaining measurement results without a temperature control system or a water bath.
Temperature Correction
The J47 refractometer corrects for errors caused by sample temperature variation using the latest ICUMSA temperature correction tables. Temperature correction is a very fast mathematical solution to obtaining measurement results without a temperature control system or a water bath. These measurement results are the most accurate when samples are comprised of predominantly sugar and water and measured near room temperature.
Standard and Ultra-Flat Sample Dishes
Refractometer performance depends on how well the instrument is cleaned between samples. The J47 has a very flat easy to clean measurement surface with no corners or crevices that tend to trap samples causing contamination. The flat low profile sample well with a sample volume of less than 1ml is easily cleaned by wiping with a paper towel. A single cleaning surface with scratch-proof sapphire prism makes the J Series refractometers popular with high throughput laboratories. The sample area is resistant to almost all solvents including Acetone, Toluene and similar organics. Hastelloy option are also available for acids like HFl and HCl.

High Durability Sapphire Prism
When using a traditional manual Abbe refractometer a high throughput application prism replacement becomes a regular task. Thus, traditional Abbe refractometers have glass prisms which are much softer than the sapphire prism of the J Series and therefore more prone to scratching and general wear and tear as described below.
Lower Cost Of Use
The traditional method of measuring Brix in a laboratory was a Abbe refractometer, sometimes with a water bath attached, sometimes not. (An Abbe with a water bath is the functional equivalent to the J57. An Abbe without the water bath is the functional equivalent to the J47). Therefore, the cost of replacing the Abbe’s dual glass prisms over time makes owning a J47 with its single sapphire prism actually less expensive than owning an Abbe over their comparable useful lives.
Calibration
The J47 Benchtop Refractometer offers a 1 or 2 point user calibration. The instrument stores the calibration information in line with ISO and similar standards. Above all, the calibration system is password protected enabling an administrator to control who calibrates the instrument.
User Configurable
Versatile instruments have advantages when applications change. However, versatility can sometimes lead to confusion by forcing operators to interpret extra results that may have no relevance. The J Series customizable display allows the instrument to configure to exactly what is required for each application. The customizable keypad can be “locked out,” or just a few keys can be operable, making for an even faster learning curve. In addition, the lockout function, calibration, and other functions are all password protected.
