.. connects 1/16" PEEK sleeves on 360µm OD fused silica - works up to 20.000psi

Didn`t we all dream of the capability to make NanoViper alike connections in our labs - just as needed? Well, maybe this dream became true....

The Zircofit concept uses a crimping tool taken from the electronics store and modified for the purpose of nanoLC sleeve crimping. The consumable part of Zircofit is a CNC lathe 1/16" PEEK sleeve with a crimp-able metal collar crafted to exactly the same 1/16" OD as a normal sleeve.

That way, one gets a PEEK sleeve with a metal section one can crimp onto the fused silica tubing. The crimping makes a rock solid connection of your sleeve onto the 360um OD fused silica - regardless of the applied LC pressure. The connection is so solid that it becomes impossible to slip / skip / slide  under LC pressure and/or LC injection pressure pulses.

Optimum system performance is often affected by sleeve related dead volumes or failure.  Consumable part can be re-ordered. An optional teflon tubing added prior crimping adds extra protection to your fused silica.

This is all you need to make reliable UHPLC compliant 1/16" sleeves onto your fused silica tubing.

Below, please find a set of pictures taken during use of the Zircofrit kit.

Once a Zircofit sleeve is put onto your fused silica tubing, one only needs to level the fused silica with the sleeve, crimp and its done. A correct crimp is so strong that one can not move the sleeve any more, forming a bond suitable for UHPLC pressures.
