J157Image

Overview

The J157 Digital Refractometer has a range of 1.33 to 1.53RI / 0 - 100Brix. The accuracy is +/- 0.00002RI / +/-0.01Brix. The communication interface is through 2 RS232, one parallel printer port and one auxiliary port.

Upto 30 User Programmable Scales can be built in this machine. The setup can be done in a few minutes by entering 2, 6 or 10 data points of concentration and corresponding RI value. Then we need to press Compute and the instrument creates a new custom scale. The customs scale could also include Butyro which is a calculated value from RI. The scales which come with the basic machine are Refractive Index, Brix, Temp. corrected RI, Temp. Corrected Brix & Urine SG.

The Auto Measure option allows the closing and opening of the presser to stand and end a measurement. The operator just closes the cover to start measuring and lifts the cover to stop measuring. The closing and lifting of the lid functions as the start/stop in the measurement process without ever touching the measure button.

J157 AUTOMATIC REFRACTOMETER

Rudolph Research Analytical, working together with Refractometer users from various countries and disciplines, has developed the J157 Automatic Refractometer. The J157 combines features and accuracy that meet the most demanding applications both in and out of the laboratory.


Application

The J157 is designed as a high accuracy refractometer for food and water based chemical applications. The instrument can read to ±0.00004 RI / ±0.03 BRIX making it more accurate and reproducible than 4 decimal place wide range chemical refractometers.


Operation

Operating the J157 is as simple as placing a sample on the prism, closing the cover and reading the answer -- all in just a few seconds. There are no shadow lines to match and there is no eyepiece requiring any kind of operator determination or manual adjustment. When the "measure when stable mode" is selected, the J157 automatically waits until the sample has been heated or cooled to a predefined temperature before intiating a measurement.


Dual Temperature Control System

Unlike other temperature controlled refractometers, the J157 has temperature control from both above and below the sample. The sample cover is controlled to the same temperature as the prism and, when lowered, is designed to provide a temperature controlled micro environment that provides unrivaled temperature stability, fast measurement time and minimal evaporation. Depending on options, the sample cover can also be used to initiate measurement.


Optional Sample Presser

The J157 is available with an optional Temperature Controlled Sample Presser that touches the sample. Compared with the standard temperature controlled cover, the optional presser reduces the empty volume of the measurement area thereby decreasing evaporation and at the same time helping to evenly spread semi solid materials over the measurement prism. This feature offers improved performance on many samples.


Auto Measure Option

The Rudolph Auto Measure Option allows the closing and opening of the presser to start and end a measurement. The operator just closes the cover to start measuring and lifts the cover to stop measuring. The closing and lifting of the lid functions as the start/stop in the measurement process without ever touching the measure button.


Easy to Clean Measurement Surface

No matter how good the refractometer is, accurate results will only be obtained if the prism is clean. The Rudolph J Series offers a flat, easy to clean prism that makes this process simple even with sticky samples.


User Defined Scales

The J157 can be supplied with a large range of standard and customized scales. Scales can be customized in a few minutes. Simply enter 2, 6 or 10 points of concentration vs. corresponding RI data, and the instrument calculates the custom scale automatically.


Calibration

The J157 offers 1 point, 2 point or a full multi-point calibration. Calibration can be done at 20°C, 25°C or any user selectable temperature within the available range. Regardless of how many times the refractometer has been calibrated, it can always be restored to the initial factory calibration if required.


User Configurable

Versatile instruments have the advantage of being able to display a lot of information, however this versatility can also lead to confusion, with extra buttons and by forcing operators to interpret extra results that have no relevance to their application. The J Series customizable display allows the instrument to be configured to exactly what is required for each application. The customizable keypad can be "locked out" or just a few keys can be operable, i.e. the measure key, print key, zero key, customer specified sample keys or any combination thereof. The lockout function, calibration and other functions are all password protected.


High Durability Sapphire Prism

The J series refractometer offers a sapphire prism for high mechanical and chemical durability. The sample well is made of 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.


Touchscreen and LCD

J257 Refractometer Touch Screen Control PanelThe J157 Refractometer’s large 7.5cm x 10cm cold cathode fluorescent back lit graphics LCD allows the scale, sample temperature, set temperature, air temperature, time, date and temperature correction status to be easily viewed. All functions are activated through a touchscreen panel which will not wear out or get misplaced like traditional or detachable keypads. The touchscreen is impervious to sharp fingernails, sharp objects, chemicals, and acids. alt 

Simple Yet Flexible

 alt Operating the J157 can be as simple as placing a sample on the prism, closing the presser and reading the answer - all in just a few seconds. The entire keypad can be "locked out" or just a few keys can be operable, i.e. the measure key, print key, zero key, customer specified sample keys or any combination thereof. The lockout function, like calibration and other functions are all password protected.

Options and Accessories

Calibration liquids from 1.33 - 1.70 (available with 4 decimal & 5 decimal accuracy).
Continuous Flow and Pour-ln Style Pressers allow samples to be continuously monitored or poured directly from a beaker. The J157 standard presser is easily removable with a captured hinge pin and replaced with a Pour-In presser as shown at right or a Continuous Flow presser with an inlet and outlet port.

Many custom scales can be built in this machine. The setup can be done in a few minutes by entering 2, 6 or 10 data points of concentration and corresponding RI value. Then we need to press Compute and the instrument creates a new custom scale. The customs scale could also include Butyro which is a calculated value from RI.

J357 AUTOMATIC REFRACTOMETER

Designed as a research quality instrument the J357 has the highest performance of any Refractometer in the Rudolph range. This instrument offers the same extra wide range as our chemical industry refractometer models combined with the high accuracy of our food industry refractometer models. It also offers the most powerful temperature control and is able to measure at up to 120 °C.


Operation

Operating the J357 is as simple as placing a sample on the artificial sapphire prism, closing the presser and reading the answer -- all in just a few seconds. There are no shadow lines to match and there is no eyepiece requiring any kind of operator determination or manual adjustment. When the "measure when stable mode" is selected, the J357 automatically waits until the sample has been heated or cooled to a predefined temperature before initiating a measurement.


Dual Electronic Temperature Control to 120 °C

Unlike other temperature controlled refractometers, the J357 has temperature control from both above and below the sample. The sample cover is controlled to the same temperature as the prism and, when lowered, is designed to provide a temperature controlled micro environment that provides unrivaled temperature stability, fast measurement time and minimal evaporation. With he Auto Measure option, the sample cover can also be used to initiate measurement.


Optional Sample Presser

The J357 is available with an optional Temperature Controlled Sample Presser that touches the sample. Compared with the standard temperature controlled cover, the optional presser reduces the empty volume of the measurement area thereby decreasing evaporation and at the same time helping to evenly spread semi solid materials over the measurement prism. This feature offers improved performance on many samples.


Calibration

The J357 offers 1 point, 2 point or a full multi-point calibration. Calibration can be done at 20°C, 25°C or any user selectable temperature within the available range. Regardless of how many times the refractometer has been calibrated, it can always be restored to the initial factory calibration if required.


Custom Scales

The J357 is available with 100 possible programmable scales. Custom scales can be set up in a few minutes. Simply enter 2, 6 or 10 data points of concentration and corresponding RI value, press Compute and the instrument creates a new custom scale.


High Durability Sapphire Prism

The J series refractometer offers 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.


Easy to Clean

alt  Easy to clean Measurement SurfacesNo matter how good a refractometer is, accurate results will only be obtained if the instrument is clean. The Rudolph J Series offers a flat, easy to clean prism that makes this process simple even with sticky sample

Built In 21 CFR Part 11 Compliant Data Storage

The J357 is available with data storage on a removable media card. In 21 CFR mode the data storage system provides a secure password system for storing raw data to comply with FDA specifications. When using non 21 CFR 11 mode the data storage system is a powerful tool for kinetics experiments and excellent system for QA traceability and to help laboratories meet the requirements of ISO and similar quality systems.


Interface

A large 7.5cm x 10cm cold cathode florescent back lit graphics LCD allows the scale, sample temperature, set temperature, air temperature, time, date and temperature correction status to be easily viewed. All functions are activated through a touchscreen panel which will not wear out or get misplaced like traditional or detachable keypads. The touchscreen is resistant to fingernails, sharp objects, chemicals, and acids.


No Water Bath Needed

alt

The J357 electronic temperature control means:

  • A significant savings on bench space because the water bath is eliminated.
  • Integrated temperature control where the instrument knows when to measure and records both the Refractive Index measurement and the temperature.
  • Hot liquid from a bath can present a significant danger in the event of a split hose, the J357 doesn't use liquid and thereby eliminates this risk.
  • Eliminating the water bath removes the most maintenance intensive part of a Refractometer. Water baths need to be regularly filled, dosed with algaecide and cleaned.

Traceability & 21 CFR Part 11 Compliance

  • All measurements are made automatically, which eliminates the need for operator judgment.
  • Calibration with fluids traceable to NIST and calibration data securely stored and available for review.
  •  Temperature can be calibrated against a traceable thermometer.
  • Operator Traceability, full 21 CFR Part 11 compliant password system.
  • Verification step with electronic signature.

Permanent Record of All Measurements

alt 

Permanent Record of all MeasurementsIn 21 CFR Part 11 mode, all measurements are written to a secure data storage card. Who used the instrument, what they measured and when it was measured is permanently stored on a locked storage media. The media card can also be used to transfer records to a computer for "backup" purposes.


Suitable for a Range of High Demand Environments

  • Petroleum Laboratories where the J357's ability to measure at up to 100ºC without a water bath makes the instrument ideal for ASTM D1218, D1747 and D5006.
  • Research Laboratories where the wide range and high accuracy of the J357 means researchers have the maximum chance of measuring newly synthesized products.
  • Central Research and Reference Laboratories where to have the most accurate results available for setting standards for an organization or a country are needed.
  • Chemical Laboratories can measure more viscous products with a level of accuracy previously available only in narrow range food instruments.
