Product Description
Teaching optical activity or running routine sugar and purity checks does not require an expensive automatic instrument. This rugged manual polarimeter delivers readings to 0.1 degree over a full circle, giving instructors and QC technicians a durable, easy-to-learn tool for measuring optical rotation. It stands up well to frequent classroom use.
This listing is for catalog number 4601P: Manual Polarimeter, model C25L. Users turn a large Vernier scale disc with coarse and fine controls to rotate the analyzer until two half-shadow fields match. A two-part quartz disc in the polarizer creates the split field, showing whether a sample is dextrorotatory or levorotatory. The optical assembly is angled 15 degrees for comfortable viewing, uses an LED source, and comes with 100 mm and 200 mm sample tubes. LIGHT LABS stocks the Heathrow Scientific line, so racks, replacement parts and consumables are easy to reorder.
Key Features
- Full ±180° range – Measures rotation in either direction around the full scale.
- Vernier scale – Reads to 0.1°, with skilled users reaching about 0.05°.
- Half-shadow quartz field – Split view makes matching and rotation direction easy to see.
- 15° tilted optics – Angled assembly allows comfortable seated viewing.
- LED light source – Long-lasting illumination with low heat.
- Sample tubes included – Supplied with 100 mm and 200 mm cells with bubble traps.
