Differential Refractometer
Differential Refractometer For Chromatography
Small or Large Amount of Samples, by YAMAZEN Technology
Yamazen's RI-31 Differential Refractometer is an exceedingly sensitive and energy efficient detector with a high intensity LED lamp which emits target amount of light at lower voltage with a built-in adjustment of light. With the PS method, RI-31 has a wider dynamic range than the conventional type and NO saturation for highly concentrated samples.
- Purification of samples from mg to dozen grams
- Fast Stabilization of the baseline
- Steady baseline even in chromatography of large flow rate (~100ml/min)
- Applicable to organic solvents

Accessories
TLC Image Reader
Rf input directly from the TLC image is possible!
Place the TLC plate on the TLC Image Reader. Just with a few clicks on the monitor, the TLC image is shot, stored, and Rf values of the target compounds are automatically calculated. Rf values are then entered as parameters to use for Automatic Method Setup and also for the sample loading software.
Column Air Purge Pump
When the run is complete, column air purge system purges the solvent from the used columns. It is better for the environment, safer in the lab and eliminates messy column removal.
External Nozzle Cleaning System
External Nozzle Cleaning System removes the crystallized samples accumulated on the outside of the fraction nozzles and cleans well. Cross contamination is a big concern in flash chromatography. The W-Prep-2XY-N cleans outside of the fraction nozzles as well as inside. Thus, pure fractions will always be collected. This device keeps entire solvent lines always clean. (Patent No. 4551364)
Solvent & Waste Monitoring System
Intelligent Fiber Optics Level Sensor System: Software coupled with highly sensitive photo detector continuously monitors the solvent amount. The software calculates and predicts the necessary amount of solvents to purify the sample upon setting up the method. Software will give a warning when the solvent becomes low and will stop the pump to prevent the columns from drying. The waste monitor prevents waste containers from hazardous and messy overflow.
