The SC-4131 single open ended XRF sample cup consists of a 3-piece set, a cup and two rings, and is tailored for enabling precise backpressure through bottom-loading of samples. The unique oversize ring delivers exceptional tautness, ensuring a smooth plane for thin film attachments, while the collar enhances stability for consistent performance. The bi-directional ring design simplifies assembly and ensures seamless integration of the ring-to-cup system, while the thermoplastic seal supports venting and pressure equalization. Perfect for handling liquids, volatiles, powders, and slurries in air or helium.
