Laminar flow

Description

The smooth, nonturbulent flow of a liquid or gas through a passage. Laminar flow provides the fastest flow rate while minimizing any mixing or diffusion in the liquid stream. Fume hoods are designed with laminar flow to efficiently remove the maximum air volume with minimal recirculation or dead spots. Additionally, the lack of turbulence in laminar flow fume hoods minimizes particle contamination.
