Sample loops for HPLC/LC injection valves, analytical-instrument fluidics, method development, and laboratory fluidic systems. Standard nominal volumes include 5, 10, 20, 25, 50, 100, 200, 250, and 500 μL plus 1.0 and 5.0 mL. All standard models use a 1/16 in (approximately 1.6 mm) connection size for straightforward selection by target injection volume and instrument configuration.
CHDLH models are organized by nominal volume, covering micro, routine, and larger-volume injection ranges for HPLC injection-valve configuration, method development, fluidic maintenance, and research-instrument assembly.
Sample loops are used in injection-valve fluid paths to define a fixed sample volume. This series spans from 5 μL micro-volume loops to 5.0 mL larger-volume loops. Select according to the analytical method, sample requirement, and instrument configuration, and confirm target volume, instrument model, valve interface, and 1/16 in connection compatibility before ordering.
Filter by volume range and volume unit to display matching CHDLH models and connection sizes.
The comparison table lists every standard CHDLH model with nominal volume, volume class, and connection size for direct side-by-side review.
