Laboratory Automation – Application based solutions for your Laboratory

Rudolph Research offers many laboratory automation options to increase productivity in your laboratory. Samples can be delivered to one or multiple instruments by means of Peristaltic Pump, Rudolph Easy Clean System, or the fully automated AutoFlex R837 system. Laboratory Automation is made simple when combined with  Rudolph Research Density Meters, Refractometers, Polarimeters, and Saccharimeters.

AutoFlex R837 – A  Flexible Laboratory 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.

Laboratory Automation – 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.

The Rudolph Research ECS (Easy Clean System) is a perfect instrument combination for Laboratories where a high volume of daily samples are required.

Laboratory Automation - Easy Clean System

The Rudolph ECS System facilitates

  • Complete cleaning between each measurement to increase accuracy.
  • Automated sample introduction
  • Waste disposal
  • Programmable cleaning and drying
  • Automatic low solvent and waste full level detection.
  • Minimal operator training required: Less than 5 minutes.
  • System Configuration minimal sample volume: 1.5 mL
  • Just place your sample in front of the instrument and press start
  • Each measurement ends with a cleaning cycle so the instrument is always immediately available for the next measurement.
  • Heated interface available.
  • Fast throughput, 2-5 min complete cycle time (Load, Measure, Cleaning, Drying)
  • Automation saves operator time and increases your lab’s efficiency.

With Rudolph’s ECS Sample measurement, cleaning, and data recording is completely automatic. The sample is measured and the data recorded. Depending on how the system is configured the data may also be printed, saved as an Excel file or transferred to a LIMS system.

Laboratory Automation - Density Meter

One or More Rudolph Instruments may be combined with various Sample Delivery Systems

Depending on the measurement and throughput requirements of your laboratory various, instrument combinations and sample delivery options may be utilized. Labs requiring two measurements such as RI and Density would use a Rudolph Density Meter controlling a Refractometer Optics Module.  Samples can be delivered via a manual injection from a syringe which would be suitable for labs with a low daily volume of samples. For labs with a larger daily volume of samples a peristaltic pump would greatly speed up sample loading speeds. For even faster sample loading and automated cleaning the Rudolph ECS system provides high throughput and automatic cleaning. Possibilities include:

  • Rudolph Research DDM Density Meter with a Manual, Peristaltic Pump, or ECS Sample Delivery System
  • Rudolph Research DDM Density Meter, Refractometer Optics Module, with a Manual, Peristaltic Pump or ECS Sample Delivery System
  • Any Rudolph Research Refractometer, Density Meter, and/or Polarimeter with a an ECS Sample Delivery System
