AutoFill™, FillStation™, and Fully Automated Sample Loading
Innovative Sample Handling Solutions from Rudolph Research Analytical
Rudolph Research offers advanced, user-friendly sample handling options designed to improve the accuracy, safety, and efficiency of polarimeter sample loading and cell handling. Whether you prefer automated filling or manual loading outside the instrument, our solutions fit a variety of lab workflows.
Simplifying Polarimeter Cell Filling – AutoFill™
AutoFill™ is Rudolph’s automated polarimeter sample loading and handling system designed for fast, reliable, and bubble-free filling of polarimeter cells — with minimal operator involvement.
Key Benefits of AutoFill™
- Easy sample loading: Simply pour the sample into the AutoFill™ chamber; no syringes needed.
- Automated operation: Press start to fill, measure, clean, and dry the cell automatically.
- Improved safety: No direct contact with acids or volatile samples.
- Consistent cleaning: Uses the correct number of solvents and drying time, saving time and effort.
- Perfect fills every time: Rudolph’s Optical Rotation Homogeneity Inspection ensures an air bubble-free cell.
Ideal for labs where analysts need quick and reliable cell loading and cleaning but do not require full automation.
Why Essential Oil Manufacturers Rely on AutoFill™
- No Syringes, No Hassle– Simply pour your essential oil sample into the AutoFill™ chamber. No pipettes needed, just pour your sample in, reducing errors and minimizing sample waste.
- One-Touch Automation– Automates filling, measuring, cleaning, and drying with one button press for fast, hands-free operation.
- Improved Safety for Volatile Compounds– Reduces operator exposure by eliminating direct contact with samples, lowering the risk of inhalation or chemical hazards.
- Perfect Fills with No Air Bubbles– Bubble-free fills are achieved by full & bubble free sample loading, improving accuracy and consistency in polarimeter measurements.
- Reliable, Reproducible Cleaning– Automated solvent rinsing ensures consistent cleaning and drying while saving time and reducing solvent consumption.
Reduce Polarimeter sample loading and cleaning time
- The cell is never manually handled, loaded, rinsed or dried.
- Cleaning and drying are simplified and nearly eliminated.
- A perfect cell load is guaranteed every time with Rudolph’s exclusive Optical Rotation Homogeneity Inspection Solution.
FillStation™ – Reliable Manual Polarimeter Sample Loading Outside the Instrument
The Rudolph FillStation™ allows users to perform manual polarimeter sample loading outside of the instrument—ideal for workflows where external preparation is preferred. Loading your sample under a fume hood is also made easy. Designed to sit on your benchtop, the FillStation™ securely holds the cell at the optimal angle for proper filling, ensuring consistent results even with minimal training.
Key Benefits of the FillStation™
Proper cell positioning: Holds the cell at the ideal 20–30° angle for filling from bottom to top.
Air bubble prevention: Filling from the lower inlet pushes air bubbles upward and out.
Visual confirmation: A built-in monitoring light glows brightly indicating when the cell is fully filled and air-free.
User-friendly: Requires minimal training, ideal for less experienced operators.
Safety: Reduces operator exposure to hazardous samples like acids and bases.
How to use the FillStation™ for Polarimeter Sample Loading
For users who prefer not to hold the cell while working with highly acidic or basic samples, the Rudolph Cell Fill Station® should be used.
| Please Note: Filling a Rudolph Polarimeter cell is easy and you can be assured of an air bubble free sample cell. It is important to note that when using highly acidic or basic solution samples the cell should not be filled in the Polarimeter; doing so may allow spillage into the instrument which, over time, may damage the instrument. The Rudolph Polarimeter Cell Fill Station® accessory is available for all Rudolph Autopol® Polarimeters and is included free of charge with Autopol® V, Autopol®V PLUS, and Autopol® VI Polarimeter Models. |
How to Fill Cells Manually
Rudolph Research Polarimeter Sample Cells
Rudolph Research polarimeter sample loading and cell handling are designed to be easily filled and cleaned with a Luer syringe.
When held at the correct angle and filled using the lower inlet port, the cell is filled with almost no possibility of leaving an air bubbles up and out of the upper outlet port.
Rudolph cells are unlike other manufacturers’ cells as they are uniquely designed to keep small air bubbles out of the light path. Filling the cell is as simple as holding the cell at a slight upward angle and filling from the bottom inlet using a Luer syringe. When the sample appears near the top outlet port, simply place the Luer cap on the upper port and then lower port. Your cell is now filled, capped and air bubble free. Cells must be clean and dry to ensure proper filling with minimum sample.
Options for Your Applications
Automation in the Essential Oil Industry
Rudolph Polarimeters is the industry standard for Essential Oil companies measuring optical rotation. Many Essential Oil laboratories also use Rudolph Density Meters and Refractometers or combinations of multiple instruments.
Adding an automatic sampling system to one or more instruments offers several benefits:
- Consistent sample loading procedures improves accuracy and repeatability.
- Greatly reduces operator error and records all measurement results with permanent storage.
- Meets the expectations of many Essential Oil manufacturers who want instruments to be clean and measurement-ready at all times.
- Eliminates the need for lab technicians to rinse and dry instruments by hand.
Using a two-sample drawer automation system with a Polarimeter allows users to measure their blank and sample in one operation:
- The method loads the blank, cleans, and then measures the sample.
- The process ends with an automatic cleaning and drying, so the instrument is always left ready to use.
All Rudolph Polarimeters can be utilized with an Automation System, carousel or drawer, with a wide selection of loading types and solvent rinses.
