MicrovolumeConnectors
Micro-unions, -tees, -crosses,and -Y’s
haveaunique two-piecedesignwhich
allowsus toprovideanextremely
small bore inaconventional ferrule
andnutfitting. Theactual connection
area is separated from thenut threads,
with the ferruledetail inametal
orpolymer insert and the threads
machined intoa stainless steel or
polymer ring. Since the inserthas
amuch smallerdiameter thana
standardone-piecefitting, it canbe
drilledwithmuch shorter tools;and,
sincea shorterdrill has less tendency
towanderorbreak,holesas small as
.006" (0.15mm) canbemachinedwith

found inall Valcofittings.

insertsprovideselectrical insulation
within the insert,while thePEEK ring
achieves total isolation.
The ringcontaining the threads
ismade fromPEEKor stainless
steel. Insertsaremadeof stainless
steel,HastelloyC,Titanium,PEEK,or
CTFE. PEEK ringsarenot as robust
as stainless steel,andarenotusable
above75°C. The stainless steel ring
withametal insert canoperateatup
to10,000psi forHPLCor SFC.
All standardValcozerodeadvolume
reducing ferrules (ZRF,FS,andFSR)
willwork in thesefittings. Theyare
uniquelydesigned tofill thevoid
between thefittingpilot and the
smaller tubingOD,eliminatingany
deadvolume in thefitting. (Reducing
ferrules suchasValco’sRF series should
beavoided,since they leavedead
volume.)
