Manual Polarimeter About
Our polarimeter P1000-LED is used by numerous companies and institutes for basic lab applications and training, for example the experiment on saccharose inversion. It measures the optical rotation according to the half-shade principle, and the measurement results are read through an eyepiece and two noniuses.The P1000-LED features a sample chamber for tubes with a length of up to 220 mm, a polariser and an analyser. A high-performance LED is used as the light source whose ser vice life is up to 2000 times longer than that of conventional sodium discharge lamps the device therefore re quires only little maintenance and is very cost-effective. A high-quality metal stand and a pivoted cover make the equipment complete.The scope of delivery for the P1000-LED includes a 100 mm and a 200 mm measurement tube with a debubbler for the proper filling.This simple, analogue device can also be validated. The sample chamber is adapted to receive our quartz control plates for the calibration and adjustment.
Accurate Optical Rotation Measurement
This manual polarimeter offers precise measurement of optical rotation, crucial for analyzing optically active compounds in labs. With a circular scale vernier and a minimum reading of 0.01, it ensures repeatable, reliable results. Its 0.02 accuracy supports demanding applications in quality control and research settings.
Designed for Versatility and Ease of Use
Accommodating sample tubes up to 220 mm long and 22 mm in diameter, the instrument features a user-friendly monocular view and a smooth, manual focus system. Its built-in sodium lamp illumination and rugged cast iron base provide the stability and clarity necessary for extended laboratory usage.
FAQs of Manual Polarimeter:
Q: How do I operate the manual polarimeter for accurate measurements?
A: To operate the manual polarimeter, place your prepared sample tube in the chamber, adjust the manual focus using the knob, and rotate the vernier scale to achieve the clearest visual reading. The sodium lamp provides consistent illumination, and the scale allows fine adjustments in 0.01 increments. Calibration can be verified and adjusted by the user as needed.Q: What types of samples can the manual polarimeter analyze?
A: This polarimeter is designed to measure the optical rotation of optically active substances, such as sugars, chemicals, and pharmaceuticals. It is suitable for solutions contained in tubes up to 220 mm in length and 22 mm in diameter, making it versatile for a range of applications in laboratories.Q: When is recalibration necessary, and how can I adjust the instrument?
A: The polarimeter is factory calibrated but may require recalibration if frequent or long-term use causes drift, or when analyzing highly sensitive samples. Users can perform recalibration using standard reference substances and follow the manufacturers instructions for scale adjustment, ensuring ongoing measurement accuracy.Q: Where can the manual polarimeter be used most effectively?
A: Its robust construction and ambient temperature operation make it ideal for educational, research, and industrial quality control laboratories. It does not require a controlled thermostat environment, but should be operated in stable laboratory conditions for best results.Q: What is the process for focusing and obtaining a reading?
A: Insert the sample tube, use the manual focus knob to clarify the field, and adjust the rotating vernier scale until the boundary line (light-dark interface) is sharply defined. The optical sensor assists with visual precision, while the scale provides a direct, non-digital degree reading.Q: How does the monocular design benefit laboratory work?
A: The fixed monocular eyepiece and 6x magnification offer a straightforward observation experience and minimize user adjustments. This ensures fast setup and reduces operator fatigue during repetitive analyses, making it practical for busy lab workflows.Q: What are the main advantages of using this manual polarimeter?
A: Its combination of durable construction, fine scale precision, user-adjustable calibration, and reliable sodium lamp illumination delivers dependable results without the complexity of digital interfaces. Supplied spares and robust support from Indian distributors add further value for laboratories across educational, research, and industrial sectors.
