Fluoropolymer-Lined Samplers

Overview

Anhui Xinfulong’s fluoropolymer-lined samplers are engineered to enable safe, contamination-free extraction of representative samples from reactors, storage tanks, and process piping systems handling aggressive, toxic, or high-purity media-. In the chemical, semiconductor, and pharmaceutical industries, sampling is a routine yet critical operation — one that must be performed without compromising operator safety, product integrity, or process continuity-.

Our samplers feature all wetted surfaces constructed from or lined with high-performance fluoropolymers — PFA, FEP, or PTFE — ensuring exceptional corrosion resistance, ultra-low extractables, and zero metal ion contamination. The fluoropolymer lining is applied over a carbon steel or stainless steel substrate, combining the mechanical strength of metal with the chemical inertness of fluoroplastics.

Whether you need to sample concentrated acids in a wet chemical plant, ultrapure chemicals in a semiconductor fab, or corrosive intermediates in a pharmaceutical reactor, our sampling solutions are designed to deliver true representative samples safely, simply, and reliably.

Key Features

Superior Chemical Resistance

• All wetted parts are constructed from or lined with PFA, FEP, or PTFE — inert to virtually all chemicals, including concentrated acids (sulfuric, nitric, hydrochloric, hydrofluoric), alkalis, solvents, and aggressive etchants

• Fluoropolymer lining provides long-term resistance to strong acids and alkalis, eliminating corrosion-related sampling failures

• Suitable for handling highly hazardous, toxic, or environmentally unfriendly media

Contamination-Free Sampling

• Fluoropolymer wetted surfaces ensure no metal ion leaching — critical for semiconductor-grade and trace analysis applications

• Extremely low extractables and particle generation maintain sample integrity

• Smooth, non-porous surfaces prevent media adhesion and cross-contamination between samples

Operator Safety

• Closed sampling system design prevents operator exposure to hazardous vapors, high-temperature media, and toxic chemicals

• Spring-loaded lever mechanism automatically closes the sampler when released, preventing accidental spillage

• Available with locking devices and safety cabinets for enhanced protection

• Exhaust ports allow safe collection and disposal of harmful gases

Representative Sampling

• Designed to extract true, representative samples without process interruption

• PFA-lined ball valve design isolates the process line from the sample bottle at all times — ideal for sampling under vacuum

• Adjustable sampling speed and volume control for consistent, repeatable results

Ease of Operation & Maintenance

• Simple 90° turning or handwheel operation for quick sample collection

• Easily disassembled for cleaning and maintenance

• Quick and easy seat replacement minimizes downtime

• Sight glass options allow visual confirmation of process stream
