As the core part of analytical instruments, the flow cell and its optical quality (surface finish) are crucial to the performance of the whole system.  For example, in flow cytometry when a sample stream is injected into the flow cell and squeezed by sheath fluid,  individual sample cells or particles are aligned in single file format based on 3D hydrodynamic focusing.  The fully integrated flow cytometry systems which include mounts, fluidics components and optics as well as hardware which enable customers to start their projects quickly.  Feel free to reach out to us by email or phone with specific dimensions, materials and tolerance as well as optical quality requirements.
