MicroTight™ Tubing Sleeves facilitate capillary tubing connections with our MicroTight accessories

Manufacturer Specific Fittings Kits are customized for specific manufacturer’s legacy HPLC systems.

IDEX Health & Science manufactures a large selection of kits, each containing an assortment of products designed to make your life easier and to save you money. Our kits range from our Super Kit – which contains a collection of many products you’ll use to accessorize your systems – to more specialized kits like our FIA kit, offering products designed to help you with flow injection analyses.

Sleeves feature an outer diameter of .025" and are available in variety of inner diameters for a broad-range compatibility with a wide assortment of capillary tubing sizes. Manufactured from PEEK polymer, these sleeves carry an upper temperature threshold of 125 °C. For proper sleeve use, choose a sleeve with an inner diameter .001"-.002" (25-50 µm) larger than the outer diameter of your capillary tubing. Then slip the sleeve over the flow path tubing, such that the tubing extends all the way through the sleeve, but not beyond the end of the sleeve. Choose the correct fitting that corresponds with your receiving port, slide it over the sleeved flow path tubing and connect as normal.
