Product Overview
The Half Shade Polarimeter Experiment Setup is a sophisticated optical instrument designed for precise measurement of optical rotation in chiral compounds. Engineered with high-quality optical glass components and durable metal construction, this polarimeter ensures exceptional accuracy and reliability in laboratory settings. The instrument operates on the principle of polarization, where plane-polarized light interacts with optically active substances, producing measurable angular rotation. This setup is particularly valuable for determining concentrations of chiral solutions or analyzing the purity of enantiomers. The half-shade design enhances measurement sensitivity by allowing precise null-point detection, minimizing human error in readings. The instrument features a robust base for stability, fine adjustment knobs for calibration, and a clear scale for easy reading. Its versatile design accommodates various sample tubes while maintaining optical alignment. The polarimeter’s optical system is optimized to minimize stray light interference, ensuring consistent performance across repeated experiments. This laboratory-grade instrument is an essential tool for any research facility or educational institution requiring accurate optical rotation measurements.
FAQs
1. What is the working principle of this Half Shade Polarimeter?
It measures optical rotation by comparing the intensity of two polarized light beams created by a half-shade device, allowing precise determination of the rotation angle when the fields appear equally bright.
2. Can this polarimeter be used with different wavelengths of light?
The instrument is typically calibrated for sodium D-line (589 nm) but can accommodate other wavelengths with appropriate filters, though recalibration may be required for accurate results.
3. What maintenance is required for optimal performance?
Regular cleaning of optical surfaces with lens tissue, proper storage in dust-free conditions, and periodic verification of zero-point calibration are recommended to maintain accuracy.
4. How does temperature affect the measurements?
Optical rotation is temperature-dependent, so measurements should be conducted at controlled temperatures or appropriate corrections should be applied using temperature coefficients of the sample.
5. What alternatives exist for measuring optical rotation?
Digital polarimeters offer automated measurements, while circular dichroism spectrometers provide additional spectral information, though these alternatives come at significantly higher costs.
