New innovations in sample handling from Rudolph Research. TECHNICAL BULLETIN 943 AutoFillTM Sample Handling The Rudolph Fill StationTM Introducing the Rudolph Research Analytical AutoFillTM (Patent Pending) Filling a Polarimeter Cell has never been easier. Rudolph Research Analytical developed AutoFil TM(Patent Pending), a simple and easy way for fast and reliable polarimeter cell loading. Polarimeter sample cel s are filled without bubbles, sample vapors are contained, and cleaning and drying is automated. Manual cell handling, cleaning and loading is eliminated. Simple operation engineered better for perfect fills every time. Operation is as simple as opening the AutoFil TM chamber, pouring in your sample, closing the lid and pressing start. The sample will be advanced into the Polarimeter cell and stopped once ful . The cell is now loaded and the measurement will automatical y begin. When the measurement is complete the operator is prompted to open the AutoFil TM chamber and add a solvent. The AutoFil TM lid is closed and the solution is flushed through the cell to waste. Air drying will automatical y begin and end. You are now ready for your next measurement. The AutoFillTM saves you time. • No need to inject samples with syringes. Samples are easily poured in the AutoFil TM sample wel . • Eliminate contact with acids and bases. • The correct amount of cleaning solvents are used for each cleaning. • Air dry is run for the correct amount of time to ful y dry the cel . • Cleaning is made effortless. Perfect for labs where analysts have no time for cell loading and cleaning,but not enough samples to justify full automation • Measurements are made without manual injection. • Cleaning is faster and drying is automated.

Sample loading and cleaning time is reduced. • The cell is never manual y handled, loaded, rinsed or dried. • The cleaning and drying process is straight forward and virtual y eliminated. • A perfect cell load is guaranteed everytime with Rudolph’s exclusive Optical Rotation Homogeneity Inspection Solution. The Rudolph FillStationTM Fill Rudolph Polarimeter Cells reliably outside of the instrument Many users prefer to load cel s with samples outside of the Polarimeter. When this fits with your work flow, Rudolph has engineered a tool to assist you, the Rudolph Polarimeter FillStationTM. Designed to sit on your laboratory bench and assist you in loading your Rudolph Polarimeter cell easily and reliably, the FillStationTM holds the cell at the right angle so you always fill the cell from bottom to top. Using a syringe, you inject the sample until it begins to appear at the top port. Once filled, the monitoring light will become bright and you know you have a full cell free of air bubbles that is ready for a measurement. Cap the top port, remove the syringe, cap the lower port and go! Advantages of using the Rudolph FillStationTM • The cell is held at the right angle and filled from the bottom just the way Rudolph cel s were designed to be filled. Perfect every time. • Filling from the bottom to top moves any air with the potential to cause a bubble up and out of the cel . • Once you see the monitoring light go to bright there is no question that the cell is properly filled. • Verification of air free sample loading for even inexperienced operators. • Helps eliminate contact with acids, bases, or any sample the user does not want to come in contact with. • Less experienced operators can learn to reliably fill cel s with minimal training. The AutoFillTM (Patent Pending) is available as an option on 2016, Autopol V Plus and Autopol VI Polarimeters The FillStationTM is included standard with all Rudolph Autopol V, V PLUS, and VI Polarimeters.

Please Note: Filling a Rudolph Polarimeter cell is easy and you can be assured of an air bubble free sample cel . It is important to note that when using highly acidic or basic solutions samples the cell should not be filled in the Polarimeter, doing so may allow spil age into Make sure the cell is always The FillStationTM creates the instrument which over time clean and dry.

Filling from the lower inlet port forces any air bubbles up and out of the upper outlet port. Rudolph cel s are unlike other manufacturers cel s as they are uniquely designed to keep small air bubbles out of the light 20° to 30° Angle 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. Cel s must be clean and dry to ensure proper filling with minimum sample.
