Dilution Bridge 1050001

SKU: 1050001

The TSI Dilution Bridge offers a straightforward and cost-effective solution for adjusting particle concentration in aerosol studies, making it a valuable tool for various laboratory applications.

Product Details

The TSI Dilution Bridge is a reliable tool for researchers seeking an efficient and cost-effective solution for adjusting particle concentrations in general-purpose aerosol studies. Its combination of simplicity, durability, and precision control makes it a valuable asset in the laboratory. It incorporates a HEPA filter and a straight tube in parallel, with needle valves enabling precise control over restriction and therefore flow in each branch. The relative amount of flow in each branch determines the dilution ratio.

A flow balance branch is also included for use in situations where the demanded and supplied flow do not match. For example, in scenarios where the aerosol generation system produces more flow than is required for the analysis with either Scanning Mobility Particle Sizer™ (SMPS™) or a Condensation Particle Sizer (CPC), the TSI Dilution Bridge provides a straightforward solution to vent the excess flow to prevent over-pressurizing the sampling instruments  Conversely, if the instrument’s required flow is less than what the source or generation system can provide, the Dilution Bridge allows drawing in clean makeup air from the environment.
