About Polarimeter Holmarc Detail

Holmarc manufactures automatic digital polarimeters for industry and research with robust performance and efficiency. Symmetric angular oscillation optical null technique by faraday modulation is implemented in our polarimeters to achieve high resolution and repeatability. Operation is simple: place the sample filled tube in the automatic polarimeter and press read button. Measurement is displayed on the soft colour lcd display of the instrument.

The polarimeter is used for determining the optical rotation of substances. By measuring optical rotation, the concentration, content, purity etc of the sample solution can be found out. Polarimeter has become one of the most useful instruments in research laboratories of sugar industry, pharmaceutical industry, oil refining, food industry, chemical industry as well as basic research in universities and r&d organizations.

Major modules in our polarimeter include light source, interference filter, polarizer, faraday modulator, sample chamber, analyzer and detector. Unpolarized light from light source (led) passes through an interference filter and polarizer so that a fixed wavelength polarized light comes out. This polarized light enters the faraday modulator and then passes through the sample cell. The modulated light which passed through the sample cell enters a second polarizer, known as the "Analyzer, which detects the angle of rotation. Finally, the light falls on a silicon photo diode which converts the light intensity to an electric signal.

Reliable Measurement of Optical Rotation

Holmarc's Optical Polarimeter delivers high precision and dependability for analyzing optical rotation in various substances. Suitable for educational, laboratory, and research applications, the instrument employs optical glass elements and a sodium lamp at 589 nm for consistent results. The robust metal body is corrosion-proof, ensuring longevity and consistent performance.

User-Friendly Manual Operation

Equipped with a practical analog scale and manual controls, this polarimeter offers straightforward operation ideal for students and professionals alike. The double image eyepiece ensures easy and accurate alignment of readings, while the supplied calibration tube simplifies regular maintenance and accuracy checks.

Versatile and Durable Design

Constructed for versatile laboratory environments, the polarimeter operates efficiently in temperatures from 10C to 40C and humidity up to 80% (non-condensing). Its compact 5 kg benchtop form factor fits easily on standard laboratory counters, and the standard sample tube ports allow quick specimen loading.

FAQ's of Polarimeter Holmarc:

Q: How does the Holmarc Polarimeter measure optical rotation?

A: The Holmarc Polarimeter measures optical rotation using a sodium lamp (589 nm) as the light source and high-quality optical glass components. The sample tube, containing the optical substance, is placed in the device. Rotating the analyzer manually aligns the observation of double images through the eyepiece, and the resulting rotation angle is read on the analog scale.

Q: What is the process for calibrating the Holmarc Polarimeter?

A: Calibration is straightforward using the included standard calibration tube. Insert the tube, follow the manual alignment process through the eyepiece, and adjust the instrument until the scale reads zero or the prescribed calibration point, ensuring accurate and repeatable measurements.

Q: When should I use this polarimeter in my laboratory workflow?

A: This optical polarimeter is ideal whenever you need to determine the optical rotation of substances, such as sugars or optically active compounds, for quality control, research, or educational experiments. It's suitable for routine and specialized analysis.

Q: Where is this polarimeter designed to be used?

A: The Holmarc Polarimeter is built for benchtop use in laboratory, educational, and research facilities. Its compact design and sturdy construction make it well-suited for varied lab environments across India.

Q: What are the benefits of the double image observation system?

A: The double image eyepiece provides a more distinct end point when adjusting the analyzer. This enhances measurement accuracy, reduces operator fatigue, and makes optical rotation readings easier to interpret, particularly when measuring low-rotation samples.

Q: How do I use different sample tubes with this polarimeter?

A: The instrument supports 10 mm diameter tubes in either 100 mm or 200 mm lengths. Simply load your sample into the chosen tube, insert it into the standard sample port, and proceed with measurement as per the operating instructions.
