AutoFlex® R837 Flexible Automation Solution
Automate your Density, Specific Gravity, Optical Rotation, Specific Rotation, Refractive Index, Brix, Urea, Color (Reflectance and transmittance), pH measurements and more.
The Standard in Flavor and Frangrance throughput
• Self-validated system – makes it so easy to run daily system validation. This can be done as often as you’d like without any daily interruption to your daily routine.
• Flexible Sample vials – Saves time, money and no decanting. Simply use the same vial you’re accustomed to , 4 Dram, 1 oz. , 1/2 oz. , 16x100mm, 13x100mm, 13x7mm, 5mL, and more.
• Heated Racks – For your heated applications we have 2 configurations available 40/10 (40 heated and 10 non-heated ) and 20/30 (20 Heated and 30 non-heated). We know that it is necessary to have non-heated availability for some control samples and the AutoFlex® R837 is the only auto sampler in the world that can fulfill that need. We make it very easy to use. It’s merely transparent to the user. The system has the intelligence to not use the heated tubes and interface when loading a non-heated sample and also to heat up the tubes and heated interface prior to loading a heated sample.
• Flexible Method Selection – With the variety of samples that are cycled in today’s laboratories we realized how important it is to have a system that can handle your samples painlessly. One of our goals in Rudolph Research Analytical is to keep things simple for the user. Each sample may require different sample load mode and/or parameters, measurement parameters, measurement criteria, temperature, cleaning parameters with solvent type, amount of solvent and drying time.
• Best unattended auto sampler system that has the intelligence to let you know when a solvent runs low and it’s time to empty your waste container.
• Most advanced safety features – The needle does not protrude at the absence of a sample vial. Turns on the heated racks in the morning and off at the end of the day.
• Robust – Build with advanced cutting-edge technology. Military grade cables and circuits to ensure top quality and redundancy. The AutoFlex® R837 is built to handle the harshest laboratory environments. Its metal frame and covers can handle any accidental chemical spills.
• Urgent sample – Allows the user to run an urgent sample without interrupting the active run.
• Import List of Sample IDs – A whole list of sample IDs can be saved and export to the instrument to automatically populate the sample sequence without the need of sample labels.
• Safety – Complies with all safety regulations (US and International)
• Low sample volume consumption – The AutoFlex® R837 uses less than 12mL for a 5 analytical instruments system (Density Meter, Refractometer, Polarimeter, Colorimeter, pH meter).
• Fast Throughput – 1.5 to 8 minutes per cycle (load, measure & clean).
Automated Data Collection
Automated sampling manages electronic data recording, sample IDs, and reduces operator errors. Test tubes and bottles can be automatically identified by the system with a built in bar code and lable reader.
• Use any format of bar codes: PDF 417, 2D Matrix, UPC, or any bar code your lab chooses.
• The bar code is recorded as the Sample ID, measurements are taken, and data is available for export to a USB, Network Server, LIMS or any data storage system.
• Labeling sample vials is also simplified as each bar code can be placed at any rotation on the sample vial or bottle because the sample vials are spun as they pass the bar code reader.
The Autoflex® R837 is engineered to work better and built to last
The Rudolph R837 Automatic Sampling System is rugged and specifically designed to stand-up in harsh laboratory and industrial applications.
• Superior material construction: Stainless Steel Needle, PTFE, Teflon, and PEEK liquid flow path materials.
• Robust needle with a sufficient torque to pierce any septum.
• Never miss piercing a sample vial with precision-engineered probe arm and sample racks which virtually eliminate misalignment errors.
• Safety guard protects hands and automated needle detects no-sample condition.
• Modular design reduces combined footprint.
The AutoFlex® R837 can be configured with various instruments and measurement methods to automate a wide range of sample viscosities. It is perfect for high throughput laboratories looking to increase productivity. The R837 is excellent when used in combination with Rudolph Research laboratory instruments in the Petroleum, Chemical, Flavor, Fragrance, Pharmaceutical, and Toxicology industries.
Eliminate sample cross contamination with complete needle cleaning – a Rudolph exclusive feature
• Self-cleaning needle eliminates cross contamination by washing both inside and outside areas of the needle between each sample. Most commercially available automation systems only flush the inside of the sample needle but neglect cleaning the outside of the needle thereby carrying over small amounts of the prior sample into new samples.
• The R837 rinses the entire system with your choice of 3 solvents between each sample.
• Low solvent level sensing: the 3 solvent bottles have a non- contact low level sensor which will prompt the user with a low solvent level message.
• Sample return feature: allows 95% of the original sample to be returned to the sample vial.
• Solvent selection flexibility: by using highly solvent resistant materials for all sample pathways, a wide variety of solvents may be used including Water, Acetone, Isopropanol, Toluene, Hexane, and Heptane.
Flexibility Unmatched with Windows Embedded
The user interface allows the operator to interrupt a measurement routine with an urgent sample. If you need to quickly find and measure a sample in the rack, the auto-find feature will search and measure for you.

Flexible Automation Solution
Automate your Density, Specific Gravity, Refractive
Index, Color, and pH measurements.
• Push the Start button and Measure Density, Specific Gravity, Refractive Index, Optical Rotation, Specific Rotation, Color, and pH. All results are exported automatically to your LIMS with a sample ID number.
• Flexible Sample Vials: Test Tubes, Boston Rounds, 1 OZ, ½ OZ, virtually any size bottle.
• Flexible rack configurations: Heated and unheated on the same carousel.
• Flexible Method Selection: Suction Mode, Pressure Mode, 3 variable rinse selections and endless drying time options.
Smart Sample Loading Technology
• SMART TECHNOLOGY™ automatically adjusts pump speed ranging from thin to high viscosity samples up to 36,000 mPa-s (cP).
• A heated rack option handles heavy crudes and waxes.
• Standard Methods: Define measurement configuration, sample load configuration (Vacuum or Gas Displacement) solvent choices, and drying time.
• No loss of accuracy or reproducibility over manually loaded samples.
Push the start button and watch your vial spin to read your barcode, QR, PDF417 , or 2D labels for the sample ID. Samples load flawlessly handles low and high viscous samples, measures your Density, SG, OR, SR, RI, Brix, L*A*B*, Gardner, ABS, %T, Cobalt, pH, then transferred automatically to LIMS, SAP or any proprietary data management system, reclaims the sample if enabled, then thoroughly cleans and dries with zero cross contamination and it’s ready for your next sample.
