Transcript Rudolph Research Refractometer, Overview Video

Rudolph Research has been a global provider and manufacturer of quality analytical instruments for many decades and was originally started in 1930.

Our guiding focus has been on Quality, Integrity, and Innovation all with a Global delivery system to reach our customers anywhere they choose to do business.

Today, I would like to introduce you to the most innovative line of laboratory refractometer instruments made today. Yes we have a refractometer for your application, and we are here to help you select the right one.

Bringing years of successful experience with laboratory instruments, Rudolph Research entered the refractometer market with bold new innovations, and features.
Years later Rudolph continues to release the most capable instruments in the marketplace.

The latest Rudolph Research line of refractometers is designed around innovations that increase performance, accuracy, and ease of use no matter what you are measuring.

We know you will make your refractometer purchase decision based on specific needs demanded by your application.

Thus our instruments are engineered so you know the instrument you buy will measure the sample you need to measure, under the conditions you need operate in.
All Rudolph Research Refractometers offer several advantages over other options.

Let’s explore the Rudolph Research Analytical Refractometer Model Line Up

The Rudolph J47 is available as both an HA model with 5th decimal place accuracy and RI range of 1.32 to 1.53 and WR model with 4th decimal and range of 1.29 to 1.66.
The instrument’s small footprint fits anywhere in your lab and cleans up easily after a measurement.
The J47 offers temperature correction as opposed to the J57 which offers Temperature Control

If you are operating a food or beverage Lab the Rudolph J57 is an excellent choice. A true laboratory workhorse offering temperature control instead of correction. Same small footprint as our J47 and also available as a HA and WR model.

Highlights of the J57 are …
Ability to give accurate results regardless of sample type
The J57 can be calibrated on non-sugar standards such as those provided by NIST
Small footprint, despite the temperature control ability, the J57 is still in the same sized package as a J47

The J57 is a perfect choice when your samples are no longer just sugar and water based

Are you looking for a solution  for measuring food samples with  the best accuracy possible or working with chemicals, then the J157 maybe your best solution

The J157 offers various instrument configurations to meet the needs of your industry or application.
The J157 also offers features to make your work easier and measurements more accurate;
Variable temperature up to 65°C very useful for samples like fats that are not liquid at room temperature
Utilizing the Windows 7 embedded OS, USB printing and saving data are easy and straight forward. The network port allows for easy data exchange.
“Load and Go” means the J157 can be operated without ever touching the screen.
Adding standard and custom scales is not a problem for the J157. Users can also create their own methods to match their workflow, sample or industry.

Need more powerful software features? The J157 with the Plus option might be what you need.
Features such as Rudolph’s trend analysis can track the behavior of a standard over time. The Load and Go feature allows measurements to be taken just by dropping a sample on the prism – no buttons to push.

Do you need to measure at higher temperatures or want total control over sample temperatures? The J157 is available with Dual temperature control from both above and below the sample

The Rudolph J257 Wide Range Refractometer – Offering the high accuracy and the widest available measurement for Polymer, Petroleum, Chemical, Pharmaceutical labs.

Highlights of the J257’s features include. Rudolph’s flat, easy to clean prism, all USP methods included, Windows 7 Embedded Operating System, Dual Electronic Temperature control, and advanced software features.
The Rudolph J257 is an excellent choice for labs who regularly measure a variety of samples with a wide range of Refractive Indexes

Does your lab measure Pharmaceuticals, Chemicals, Petroleum, Essential Oils, Fragrances, or Cosmetics?

The Rudolph J357 is the instrument that measures them all.

The Rudolph J357 is designed to be a research quality instrument offering a wide RI Measurement range and the high accuracy required to satisfy the most demanding laboratories and regulations.
The J357 is available with the software features needed to comply with 21 CFR Part 11 making it a top choice for highly regulated Pharmaceutical laboratories.
The Rudolph J457 completes the Rudolph refractometer line. The J457 is our most capable and versatile refractometer. Designed to be configured in several ways the J457 can be adapted to your working environment to make your work flow easier.

The J457 incorporates a split instrument design that allows the optics portion of the instrument to be separated from the display and “Computer” portion of the instrument.

The J457-SC is the standard Benchtop configuration with the two sections of the instrument placed together.

The J457-WC has the optics box on a bench or table with the display portion mounted up and away from spills on the wall.

J457-FC Refractometer in Factory Configuration is recommended when there is a lot of sample spillage on the laboratory’s instrumentation. Factories working with sticky resins and syrups that end up being spilled on the instrumentation are great candidates for the J457-FC as the measurement unit can be as much as six feet away from the display unit.
