Conductive MicroTightUnions
The Upchurch Scientifc Conductive MicroTight Unions manufactured
by IDEXHealth&Science provide an excellent opportunity to introduce
voltage into an electrospray or capillary electrophoresis system. With
an extremely low internal volume of 16 nL or 5 nL, these unions can be
placed inlinewith 360 μmor 1/32”ODcapillary tubing. Mount and apply
voltage to these unions using our Insulating Mounting Bracket below.
InsulatingMountingBracket
Use our Insulating Mounting
Bracket to easily integrate the
Conductive Mini MicroFilters
shown above into your system
or lab.
The product snaps into place.
Voltage from your lead wire
is conducted through the
attaching stainless steel nut
and screw (included), then
onto the mounted product
via the stainless steel clip.
The bracket’s base includes two holes (#2 screw clearance) for easy
mountingontoany labsurface. Dimensionsare1.25”Lx0.45”Wx0.63”H.
Insulating Mounting Bracket, shown with lead wire and
Conductive MicroTight Union, not included.

Application Note
MicroTight
®
Connectors for Capillary Tubing
Connect two pieces of capillary tubing with these Upchurch Scientifc
®
PEEK
™
MicroTight Connectors. The True ZDV Unions allow two pieces
of tubing to connect directly to each other—using the included gauge
plug to ensure proper alignment. The standard union and elbow both
feature a 0.006” (0.150 mm) thru-hole, adding only a small amount of
additional fow-path volume to help ensure proper chromatographic
results. For MicroTight unions designed for UHPLC applications, see
page 37.
