ROTI®Cell Colcemid solution is a CELLPURE sterile preparation at 10 µg/ml in DPBS for cell-culture workflows that require a defined colcemid reagent. The active component is referenced under CAS number 477-30-5. Density is approximately 1 g/cm³ and the boiling point is 100 °C, consistent with an aqueous buffered medium. Offered in a 10 ml pack from manufacturer Carl ROTH, the solution is suited to cytogenetic and related cell-biology procedures where metaphase arrest or controlled mitotic disruption is part of the protocol. The sterile CELLPURE presentation supports clean handling in routine laboratory practice. Clear concentration and matrix information help standardise dosing across experiments, while the compact volume fits both method setup and ongoing culture work that depends on reproducible colcemid exposure in DPBS. This article belongs on Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.
