Viper finger-tight fitting

Provides ease of use and dead-volume free plumbing of every conventional HPLC and UHPLC system

Provides zero-dead volume fingertight connections
Supports operating pressures up to 1,500 bar (22,000 psi)
Available in different lengths: 65mm and from 150 to 950mm in 100mm steps
Available in different inner diameters: 0.1mm (0.004 in), 0.13mm (0.005 in) or 0.18mm (0.007 in)
Easy to use due to stainless steel or biocompatible MP35N™ capillaries (1/32 in OD) and fingertight design
Works with virtually any valve and column from any manufacturer
Fits narrow connections such as 10-port valves and enables mixed use with different designs

PEEKsil capillary tubing

Excellent chemical compatibility and very low carryover3

Precision-bore fused silica tubing coated with 1/16in OD PEEK covering
Usable in most standard chromatography systems
Withstands high pressures
Smooth internal surface for excellent flow characteristics
Tubing is stiff: not recommended for uses requiring tubing bends
Precut lengths only: cutting in the lab may damage tubing

316 stainless steel capillary tubing

Cleaned, polished, passivated and ready-to-use

Suitable for ultra high pressure applications
Wide chemical compatibility
Prefinished, square, burr-free ends and interiors to minimize dead volume connections
Not recommended for biological samples
Rough internal surface may lead to sample carryover

PEEK Capillary Tubing

Pre-cut and color-coded for easy identification and use

Broad chemical compatibility
Biocompatible
Easily cut to desired length
Appropriate for many HPLC applications
Resistant to most organic solvents, except for nitric acid, sulfuric acid, dichloromethane, THF and DMSO

High pressure stainless steel nuts and ferrules

Accommodate a wide range of configurations

Designed for 10-32 port configurations
Burr and contaminant free

Rheodyne 7725 and 7725i Sample Injectors

Allow continuous flow between the load and inject positions to protect against pressure shock

Stainless steel construction
Make-Before-Break (MBB) design
Can use partial filling for zero sample waste or complete filling for better reproducibility
Inject 1μL to 5mL with high accuracy and precision
7725i features a position sensing switch for a reproducible start signal.

Also available are Rheodyne 9725, Rheodyne 9725i, Rheodyne 8125 low-dispersion microscale, Rheodyne 7010, and Rheodyne 9010 injectors.
