Product Overview
Our High-Purity PTFE Tweezers (Teflon tweezers) are engineered for demanding laboratories and semiconductor manufacturing. While traditional metal tweezers risk acid corrosion and metallic ion contamination, and standard plastic tweezers warp under high heat, our PTFE tweezers offer complete chemical inertness and non-marring performance. Machined from 100% virgin PTFE, they ensure scratch-free, contamination-free handling of delicate wafers, membranes, and aggressive chemical samples from cryogenic liquid nitrogen (-200°C) to high-temperature environments (+250°C).
Key Features
-
Exceptional Chemical Inertness: Impervious to concentrated acids (Aqua Regia, HF), strong bases, and organic solvents (pH 0-14).
-
Extreme Temperature Tolerance: Performs reliably from -200°C to +250°C (-328°F to +482°F) without melting or embrittlement.
-
Ultra-Pure & Contamination-Free: 100% virgin PTFE without metal ions or plasticizers, ideal for trace analysis (ICP-MS).
-
Non-Stick & Static-Safe: Ultra-low friction coefficient prevents particle adhesion; excellent dielectric properties protect sensitive electronics.
-
Versatile Configurations: Available in pure PTFE body, cross-locking (reverse-action) self-closing design, and hybrid steel-handle models.
Design Options
-
Cross-Locking (Reverse-Action) Design: Features a "normally closed" self-closing mechanism that opens when squeezed and locks automatically when released. Perfect for reducing hand fatigue during extended acid baths, ultrasonic cleaning, or continuous sample holding.
-
Stainless Steel Body + PTFE Tips: Combines the structural rigidity and tactile feedback of a stainless steel handle with non-scratching, corrosion-resistant PTFE working tips. Ideal for high-frequency industrial assembly.
Primary Applications
-
Chemical & Scientific Research: Handling samples in strong acid/alkali baths, aggressive solvents, and trace element analysis.
-
