Product Specifications: PTFE Crucibles
Overview
Premium laboratory crucibles molded from ultra-pure Polytetrafluoroethylene (PTFE). These vessels are specifically engineered for highly sensitive analytical applications, trace metal analysis, and tasks involving aggressive chemical reagents where traditional porcelain or glass vessels would fail or introduce contamination.
Technical Data & Key Features
-
Resistant to High Temperatures: Thermally stable under continuous operating temperatures up to 250°C to 260°C.
-
Ideal for Mixing and Heating: Perfect for sample digestion, chemical mixing, and uniform thermal transfers within its operational temperature threshold.
-
Non-Stick, Non-Reactive Surface: Features an exceptionally slick, ultra-low surface energy finish that resists sample adhesion, ensures minimal residue, and eliminates chemical cross-reactivity.
-
Contamination-Free Profile: Virgin PTFE compound provides an inert barrier to strong mineral acids (including hydrofluoric, nitric, and sulfuric acids), alkalis, and complex organic solvents.
Sizing & Configurations
Each unit features a tapered body profile for stable bench handling and includes a matching, easy-grip PTFE lid featuring a central vertical knob for safe removal using tongs or gloves.
