Rotary selector for use in liquid analyzer, has groove provided on proximal ring on outer boundary of barrel and/or on wall of cavity of body to form pipe conveying liquid from proximal orifice towards two perforations of proximal ring
Rotary selector for use in liquid analyzer, has groove provided on proximal ring on outer boundary of barrel and/or on wall of cavity of body to form pipe conveying liquid from proximal orifice towards two perforations of proximal ring
The selector has a barrel (2) with a distal orifice that is open on a perforation (21) of the barrel, where the perforation is open on a proximal orifice placed opposite to a proximal ring (CP) of a body (1). A connection groove (16) is provided on the proximal ring of the body on an outer boundary of the barrel and/or on a wall of an inner cavity of the body to form a pipe conveying the liquid to be analyzed from the proximal orifice of the barrel towards two perforations (12, 13) of the proximal ring of the body located in an upper angular sector.
