Product Introduction
Our High-Purity PTFE Reagent Bottle is engineered for demanding laboratory environments, trace-metal analytical applications, and chemical synthesis processes. Manufactured from 100% pure virgin PTFE (Teflon), this vessel provides outstanding chemical resistance against virtually all corrosive chemicals, including hydrofluoric acid, nitric acid, aqua regia, and aggressive organic solvents.
Built to withstand extreme thermal conditions, it maintains structural integrity and seal efficiency across temperatures ranging from -200°C to +260°C (-328°F to +500°F). With near-zero background interference and minimal metal ion leaching, it ensures your sensitive samples and high-purity reagents remain untainted during storage and testing.
Designed with lab efficiency in mind, the bottle features vertical reinforcing ribs along the neck and cap for enhanced torque and effortless opening—even when wearing safety gloves. The precision-machined neck thread delivers a dependable, leak-proof closure to prevent hazardous reagent fumes from escaping. Available in both Wide-Mouth (ideal for solids, powders, and viscous samples) and Narrow-Mouth (designed for liquid decanting and volatility control) configurations.

Detailed Features & Technical Innovations
| Feature | Design Highlights & Performance Advantage |
| Reinforcing Ribs Design | Engineered vertical ribbing around the neck and cap enhances structural rigidity, prevents bottle deformation during thermal cycles, and offers extra torque leverage for easy opening and closing even with gloves. |
| Stable & Anti-Tip Base | Flat, thick, precision-machined bottom provides a low center of gravity and excellent heat transfer efficiency when placed on hot plates. |
| Acid & Alkali Resistance | Unaffected by organic and inorganic reagents. Perfectly safe for Hydrofluoric Acid (HF), Nitric Acid ($HNO_3$), Sulfuric Acid ($H_2SO_4$), and Sodium Hydroxide ($NaOH$). |
| Precision Neck Thread | Smooth standard threads ensure tight interlock and airtight sealing to prevent evaporation of volatile reagents. |
Buying Guide: Wide-Mouth vs. Narrow-Mouth
