Description
The Standard in Purity: 316L Medical-Grade Steel
The Revomax 20oz is built around one principle: what you pour in is exactly what you should taste. Unlike standard bottles that use 304 stainless steel, our interior is crafted from 316L medical-grade stainless steel — the same alloy trusted in surgical instruments and medical implants.
Why 316L Makes the Difference
316L contains 2-3% molybdenum — an element that dramatically increases resistance to pitting corrosion from acids, chlorides, and salts. With a Pitting Resistance Equivalent Number (PREN) of 23-28 versus just 18-20 for standard 304 steel, 316L ensures unparalleled purity:
| Property | Standard 304 Steel | Revomax 316L Steel |
|---|---|---|
| Molybdenum Content | 0% | 2-3% |
| Carbon Content | 0.08% max | 0.03% max (Low Carbon) |
| Acid Resistance | Moderate | Superior |
| Metallic Taste Risk | Yes, especially hot/acidic drinks | None |
| Medical Classification | Food-grade | Surgical-grade (ISO 5832-1) |
| Nickel Leaching | Higher risk | Significantly lower |
Engineering & Performance
Patented Twist-Free Lid — US Patent Protected
The world's most advanced bottle cap. Our threadless system uses a double seal, triple lock mechanism that replaces the 160-year-old screw lid:
- ⚡ One-hand open/close in under 1 second — safe for driving.
- 🔒 Zero leaks in any orientation — tested and trusted in backpacks and gym bags.
- 🧼 3-second full disassembly — every component is accessible for thorough cleaning, eliminating hidden mold spots.
- 💪 Pressure-safe for carbonated drinks — engineered to handle CO₂ buildup safely.
Industry-Leading Insulation
Double-wall vacuum insulation, enhanced by the patented lid's superior airtight seal:
- ❄️ Cold: Up to 36 hours — ice retention from morning to the next morning.
- 🔥 Hot: Up to 18 hours — pour coffee at 7AM, still hot at midnight.
- 📉 Outperforms screw-lid competitors by 15-20% due to eliminated thread thermal leakage.
