Multi-Fluid BLAM

A new revision of the BLAM nozzle for further versatility and control. The 4 fluid nozzle, available for BLAM applications, adds two additional liquid feed ports to the efficient atomizing nozzle. This makes for a total of 3 liquid feed ports and each can be individually controlled.

With up to 3 non-mixing liquids, different test articles, or different test article concentrations each having the capability to be metered to the atomizer in various flow rates allows for a wide range of applications such as micro-encapsulations or multimodal size distributions.

This nozzle is available in the jar module providing the standard BLAM features and accessories, but is also available in sanitary pipe connections. Standard or low carrier gas flow is available for this nozzle for a wide range of concentrations. Different expansion plates are available for generating less vacuum on the liquid feed ports for higher precision of the test article delivery feed rate similar to the standard single jet model.
