Sheath Flow Cell, ≥50 µm Sheath Channel (CAT#: STEM-AL-7638-ZJF)

The sheath flow cell is a precision optical sheath-flow cell intended for hematology, flow cytometry, particle counting, and bacterial separation. It is designed to focus and guide particles through a defined sheath-flow detection region. The construction uses optical glass, quartz glass, or sapphire crystal with high-strength bonded construction. The optical or fluidic configuration provides four-sided optical access through a highly polished detection zone. Its measurable characteristics are defined by the dimensional, surface, transmission, or operating parameters stated in the source. The component can be integrated through the fluidic and optical interfaces of compatible analytical instruments. The design is intended to maintain repeatable optical or fluidic behavior within its stated application. Overall, the product provides a controlled sheath-flow path for laser or optical particle detection.
