Making Swagelok connections

    The DXR-GM cell and G-01 control box use Swagelok connections throughout.  In the course of experimental work you will sometimes need to break or re-make some of these couplings.  Swagelok issue the following rules for these procedures.

1. New installations - making a connection for the first time.

    Assemble the components of the joint and make the joint finger-tight.  Mark each part with a pen or pencil.  Hold BOTH parts of the joint with spanners.  Then for ¼" diameter tube, tighten by 1¼ turns.  For 1/8" or 1/16" tube follow the same procedure but tighten by only ¾ turn.

2. Re-making joints.

    Assemble as above and make finger-tight.  Then with spanners make a further ¼ turn (all tube sizes).

Review Rheodyne® Model 3725 Prep-Scale Injectors

• Sample range 100μL to 20mL
• Flow rates from 10 to 800mL/min
• Uses 16-gauge needle
• 1.0mm (0.04") flow passages

These injectors are used with preparative HPLC columns from 1 to 10cm diameter. They have the ease of use and versatility of Rheodyne’s analytical-scale sample injectors, plus the capacity for large sample volumes and flow rates. The Model 3725 Valves are available in stainless steel or PEEK, and with a built-in position sensing switch (Model 3725i-038 or 3725i). Each model is supplied with a 10mL loop and 1/8" fittings must be used. An optional port adapter can be used to connect 1/16" tubing. Suitable for pressures up to 5000psig.
