The cell measures 200 mm in path length and holds 18 mL of sample, constructed from clear glass. The doubled path length compared to the standard 100 mm cell provides doubled sensitivity for optical rotation measurements — particularly valuable for dilute solutions, low-rotation samples, or applications requiring enhanced measurement precision. The integrated bubble trap migrates air bubbles away from the optical path, ensuring clean, bubble-free readings.\u003c\/p\u003e\n\n\u003ch2 class=\"mb-2 mt-4 font-display font-semimedium text-base first:mt-0 md:text-lg [hr+\u0026amp;]:mt-4\"\u003eFeatures \u0026amp; Benefits\u003c\/h2\u003e\n\u003cul class=\"marker:text-quiet list-disc\"\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\n\u003cstrong\u003e200 mm Path Length — Doubled Sensitivity:\u003c\/strong\u003e At twice the path length of the 100 mm cell (4600P-SC100), the 200 mm cell doubles the observed optical rotation value for any given sample concentration.

Pharmaceutical labs testing optical rotation of dilute API solutions — where the 100 mm cell reading falls near the instrument's resolution limit — use the 200 mm cell to double the observed rotation and obtain a more definitive result. Academic teaching labs use the 200 mm cell when demonstrating optical activity in sucrose or tartaric acid solutions at lower concentrations. Food QC labs working with near-threshold sugar concentrations benefit from the enhanced sensitivity.
