Rudolph Research Analytical is global Manufacturer of Refractometers, Polarimeters, Saccharimeters, Consequently, Mr. Rudolph & Sons, Inc.

The company was founded in 1930 by Otto Curt Rudolph, who imported microscopes, polarimeters, saccharimeters, and other scientific instrumentation manufactured in Europe. Scientific instrument importation was not possible after the outbreak of World War II. Rudolph began to manufacture a standard line of polarimeters, and undertook the custom design and manufacture of instrumentation for universit

ies and laboratories. Since that time, the company has been engaged in research, design, manufacture, sales and service of products utilizing light as a measurement medium. In 1970, the company changed its name from O.C. to Rudolph Research Corporation. The name was changed to reflect the modern and innovative philosophies of the company. Rudolph Research began expanding its products to include a standard line of automatic ellipsometers, polarimeters and saccharimeters, as well as accessories for those instruments. Various models of these instruments are used in pure and applied research by universities, independent laboratories, government laboratories and industry. In addition, Rudolph Research production ellipsometers find widespread application in the semiconductor/integrated circuit industry where the measurement of film thickness in the angstrom region is important. Automatic polarimeters are used for research and process control in the pharmaceutical, food and beverage, chemical and related industries. Automatic saccharimeters are used routinely by sugar growers, processors, and refineries, as well as by governments to regulate both domestic and international sugar trade.

Many beverage laboratories struggle with one common issue during density testing: bubbles in the sample tube. Even small bubbles can impact measurement accuracy, create repeat testing, and slow down production workflows.

Rudolph’s DDM 2911 PLUS Density Meter helps solve that problem with VideoView™ bubble detection technology. Operators can visually confirm proper sample loading directly on the instrument, helping reduce sample errors before a measurement is even taken.

For beverage, pharmaceutical, petroleum, and chemical laboratories, this means:

• Improved confidence in measurement results
• Reduced retesting and wasted samples
• Faster workflows and better operator consistency
• More reliable density and concentration measurements

The DDM 2911 PLUS is designed to support laboratories that require both speed and precision while maintaining compliance with industry standards and quality requirements

In food and beverage production, small variations in Brix measurement can create major downstream issues — from inconsistent product quality to unnecessary batch adjustments and rework.

The Rudolph J57-VT Automatic Refractometer was designed to help QC laboratories improve both speed and confidence in refractive index and Brix testing.

With:
• Electronic temperature control from 10°C–65°C
• Sapphire prism durability for high-throughput environments
• Fast automatic measurements with minimal operator influence
• Accuracy up to ±0.01 Brix
• Calibration to traceable standards

The J57-VT helps laboratories reduce variability while improving workflow efficiency in demanding production environments.

For manufacturers processing syrups, sauces, beverages, flavors, or sugar-based products, reliable refractive index measurements are critical to maintaining consistency from batch to batch.

Rudolph Research Analytical is excited to share that we will be attending the upcoming Health Connect Partners Reverse Expo, May 18th-May 20th.

Dave Oehler will be discussing our VeriLinkRx® system. An innovative, analytical solution designed to help hospital pharmacies verify the integrity of returned narcotics quickly and cost-effectively.

With VeriLinkRx®, staff can:
• Detect tampered or sub-therapeutic dosage levels in returned medications
• Identify potential drug diversion, including dilutions or substitutions in narcotics like morphine, hydromorphone, oxycodone, and fentanyl
• Strengthen existing chain-of-custody protocols with real analytical verification

If you’ll be attending the Health Connect Partners Reverse Expo, we’d welcome the opportunity to connect and discuss how VeriLinkRx® can support your organization's goals.

We look forward to seeing you there!

Many laboratories still rely on manual sample handling across multiple instruments for tests like refractive index, optical rotation, density, pH, and color.

At first glance, that process may seem manageable.

But the real cost is often hidden in technician time, repeated sample handling, data entry risk, lower throughput, and avoidable errors.

When every sample requires multiple touches, the lab pays for it in labor, inefficiency, and lost capacity.

Laboratory automation changes that by allowing multiple measurements from a single sample load. The result is faster workflows, better traceability, reduced human error, and more productive use of skilled staff.

For liquid product laboratories testing flavors, fragrances, beverages, liquid foods, nutraceuticals, oils, and lotions, automation is not just about speed.

It is about building a more efficient, scalable, and reliable operation.

Rudolph Research Analytical automation systems help laboratories reduce manual handling, improve data integrity, and unlock higher productivity from every sample.

Beverage QC teams are under pressure to do two things at once:

Measure Faster and Be More Accurate.

That is not always easy when even small errors in alcohol or density measurement can lead to:
batch delays, retesting, labeling risk, and avoidable compliance issues.

In our experience, the conversation should not just be about running a test. It should be about whether the result is precise and repeatable enough to support a real production decision.

Better measurement helps teams do more than verify a batch.
It helps them improve consistency, reduce uncertainty, and keep operations moving.

Where do you see the most pressure in beverage testing today, faster throughput, tighter compliance, or reducing repeat measurements?

A sincere thank you to everyone who visited our booth at Pittcon.

It was great to see familiar faces, meet new people, and have so many meaningful conversations throughout the event.

We’re grateful to our customers for their continued support, and we also want to thank the many potential new customers who took the time to stop by and learn more about what we do.

Pittcon is always a great opportunity to connect, share ideas, and explore new possibilities, and we’re thankful to everyone who helped make this year’s event such a success.

We look forward to continuing the conversations and building new partnerships in the weeks ahead.

Hospitals Need a Better Way to Catch Drug Diversion- VeriLinkRx® Guarantees

Did you know that up to 15% of healthcare professionals may struggle with drug dependence during their careers?

➡️ Drug diversion - when narcotics are tampered with, diluted, or replaced before being returned to the pharmacy.

This contributes directly to the growing issue of drug diversion, where narcotics are tampered with, diluted, or substituted before being returned to hospital pharmacies.

📢 Biometric scans and witness signatures aren’t catching it all.
What if your hospital could detect diversion before those drugs reach the patient—or go missing entirely?

✅ Meet VeriLinkRx® — The In-House Narcotics Testing Breakthrough
