2.2.2 Reagent Tubing Kit
Securely connect each tubing line to the appropriate port on the back of the unit (see detail diagram, page
8). Ensure the 3 luer fittings are tight by twisting the blue portion counterclockwise. Use the Fastener Tool
provided with the SPE-Express unit to tighten the Hexane, DI Water and Methanol lines.
• Hexane
• Deionized Water
• Methanol
• Vacuum
• Water Miscible Waste
• Hexane Waste
WARNING: Fluid connection, pressure must always be removed before disconnecting bottle harness from unit
to prevent leakage of chemicals. (Reference “Detaching the Bottle Harness” section for instructions for safe
removal of the bottle harness).
Replace reagents and waste container caps with the appropriate caps within the Bottle Harness. Ensure
Bottle Harness caps are tight on reagent bottles to prevent leaking.
Attach the Reagents Hose provided to the Bottle Harness manifold labeled “Pressure”.
Attach the Vacuum source to the Bottle Harness manifold labeled “Vacuum”.
Do not place reagents higher than the SPE-Express as it will affect spray volume performance.
Place reagents level with the SPE-Express or within 36" below.
CAUTION: Reagent bottles are under pressure while Nitrogen is supplied to the unit and reagents hose is
attached; never loosen reagent caps with Nitrogen supplied.
2.2.3 Nitrogen Ports
Ports are provided to control your Nitrogen flow.
Nitrogen from Source
The “Nitrogen - from Source” uses a hose with an Industrial-Shape Hose Quick Connect 0.25" Socket. The
other end should connect to the Nitrogen supply.
Nitrogen to Reagents
Connect the Reagents Pressure Hose Plug (opposite from the end connected to the “Pressure” manifold of
the Bottle Harness).
