Is Clear PVC Tubing Compatible with Cleaning Fluids? Clouding and IVD Validation
Compatibility has two directions: can the cleaner change the tubing, and can tubing contact affect the assay? Cleaning-fluid exposure and background measurements help connect material screening with IVD device validation.
Why Does Tubing Pull Off Barbed Fittings? PVC Pressure and Pull-Off Tests
A fitting can release before the PVC tube bursts, and high pull-off force does not directly establish working pressure. FOREACH tests on two tubing sizes show how to measure and interpret pressure and post-aging retention before validating the installed IVD fluid path.
What Is PTFE Tubing? Properties, Limitations and Selection for Instrument Fluidics
PTFE tubing is fluoropolymer tubing made from polytetrafluoroethylene, considered for reagent, wash-fluid and solvent lines in instruments. Select fluid compatibility, ID/OD, temperature, pressure and fittings together to meet transfer, sealing and internal-volume requirements.
What Is FEP Tubing? Properties, Dimensions and Connections for Transparent Fluoropolymer Tubing
FEP tubing is made from fluorinated ethylene propylene, a fluoropolymer with broad chemical resistance that can be formed into transparent small-bore tubing for fluid observation. For instrument fluidics, select fluid compatibility, ID/OD, length and end connections together.
What Is PFA Tubing? Material Properties, Cleanliness and Instrument Fluidics
PFA tubing is fluoropolymer tubing made from melt-processable perfluoroalkoxy polymer. In analytical fluidics, check fluid compatibility, internal volume, connections and analytical background together so material selection defines a complete assembly.
What Is PVC Tubing? Hardness, Dimensions and Fittings for Instrument Lines
Flexible PVC instrument tubing is made from a polyvinyl chloride compound and commonly used where flexible routing and liquid observation are needed. Select hardness, ID/OD, wall thickness, fluid and fittings together, distinguishing ordinary connection tubing from dedicated peristaltic pump tubing.
