Multi-channel distributor doser - has divider unit in form of head with coupling acting as manifold and support for intermediate tubes

摘要

A multi-channel distributor/doser, e.g. for simultaneous dosing of small and equal quantities of liq. such as reagents, consists of a series of outlet tubes (14) which are connected through a divider unit (16, 17, 18) to a manifold coupled to the outlet channel (9) of a doser. The divider unit is in the form of a head (16) with a coupling (17) which acts as the manifold and a support (18) for intermediate tubes (20) which are joined to the outlet tubes (14). The coupling has a truncated conical recess which is connected to the outlet channel and has a coaxial conical projection inside it, and each of the intermdiate tubes is connected to one of the outlet tubes via a flexible connector (31). ADVANTAGE - greater precision with simplicity and low cost.
