Overview
Designed for demanding chemical synthesis, reaction setup, and trace-element research, our PTFE Three-Neck Flask provides an uncompromised solution where glass risk, HF contamination, or strong corrosive agents are present. Featuring three standard ground joints (e.g., 24/29, 24/40 options), this vessel easily integrates with condensers, addition funnels, stirrers, and temperature sensors.
Its unique threaded body joint and fully modular structure ensure complete seal integrity under atmospheric reaction conditions while allowing convenient disassembling and cleaning.
Key Highlights (Bullet Points / Highlights)
-
High-Purity PTFE Material: Manufactured from 100% virgin PTFE (Polytetrafluoroethylene), offering superior thermal stability, non-stick properties, and absolute chemical inertness.
-
Exceptional Chemical Resistance: Virtually unaffected by strong acids (including Aqua Regia and Hydrofluoric Acid), alkalis, oxidizers, and organic solvents.
-
Wide Operating Temperature Range: Performs reliably across extreme thermal environments from -200°C to +250°C (-328°F to +482°F).
-
Precision Modular & Threaded Design: Features standard ground joints with removable neck adapters and fine-threaded body sealing for leak-free, easy-assembly, and effortless cleaning.
-
Unbreakable & Shatterproof Safety: A durable, shatterproof alternative to traditional borosilicate glass reaction flasks in high-risk or trace-element laboratory applications.
Key Performance Features
-
Unmatched Chemical Inertness
-
Impervious to nearly all chemical reagents, including concentrated Hydrofluoric Acid (HF), Aqua Regia, perchloric acid, and aggressive organic solvents. Ideal for semiconductor wet chemistry, fluorochemical synthesis, and trace analysis.
-
-
Extreme Thermal Resistance & Stability
-
Maintains mechanical strength and structural integrity under continuous working temperatures up to 250°C (482°F) and continuous cryogenic environments down to -200°C (-328°F).
-
-
Smooth, Non-Stick & Contamination-Free Surface
-
Ultra-smooth interior finish prevents liquid retention, sample contamination, and crystal adhesion, ensuring high recovery rates and easy decontamination.
-
-
Engineered Precision & Leak-Proof Joint Fit
-
Precision-machined 24/29 (or custom) ground joints ensure tight, precise mating with PTFE or glass components. The heavy-duty threaded collar coupling provides tight sealing without risk of thread jamming or seizure.
