Inlet Probe: Temperature Range -20°C to 150°C, Diameter 3-10 mm

Component Specifications

Definition

A precision-engineered component designed for automated sample acquisition in analytical instrumentation, featuring controlled fluid dynamics, contamination prevention mechanisms, and compatibility with various sample matrices. It serves as the primary interface between the sample source and the analytical system, ensuring representative sampling while maintaining system integrity.

Working Principle

Operates through pneumatic or mechanical actuation to extend into the sample medium, create a pressure differential for fluid aspiration, and retract while maintaining a sealed pathway to prevent contamination. Incorporates flow control mechanisms and self-cleaning features to ensure consistent sample delivery.

Materials

316L stainless steel (primary wetted parts), PTFE/PEEK fluid pathways, ceramic tips for abrasive resistance, FDA/USP Class VI compliant elastomers
