BioTight™ fittings

New biocompatible fitting system for tight spaces

The newly introduced IDEX BioTight™ fitting system provides consistent biocompatible performance in low-pressure 1/4-28 flat-bottom port assemblies. These fittings are ideal for tight spaces and require very little torque thanks to the metal-free press-fit ferrules made from PEEK. One universal BioTight™ PEEK nut accommodates all tubing diameters, and the fitting assemblies are pressure stable up to 200 psi (14 bar) for 1/16” OD tubing, and up to 100 psi (7 bar) for 1/8” OD tubing.

The BioTight™ fittings are easy to install into tight spaces and guarantees a completely metal-free connection. The low torque ensures that the fittings can be reassembled numerous times both with rigid and semi-rigid tubing materials. These features make the BioTight™ fittings ideal for low-pressure biotechnology fluidic applications such as, genomics, spatial biology, next generation sequencing, invitro diagnostics, and biochromatography.

Installation guide

Instructions

1. Slide the fitting onto your tubing and add the black-coloured lock ring, ensuring the ridge feature faces the fitting for 1/8-inch tubing.
2. Slide the ferrule tube onto your tubing.
3. Place the components into your intended port, inserting the port thread into the fitting while keeping pressure on the tube.
4. Tighten the nut. Continue until you feel the lock ring bottom-out in the port. It’s that simple.
