About This

• LABORATORY-GRADE BOROSILICATE GLASS CONSTRUCTION Crafted from premium borosilicate glass (ASTM E438 Type I certified), the upper chamber (360ml/3-cup capacity), lower chamber, and integrated alcohol burner withstand extreme temperature fluctuations from -30°C to 180°C (-22°F to 356°F). This laboratory-grade material provides superior thermal shock resistance—a critical safety feature that ensures structural integrity during rapid temperature changes typical of professional coffee brewing cycles.
• STABLE 304 STAINLESS STEEL BASE WITH MULTI-HEAT SOURCE COMPATIBILITY Features a wide-angle 304 stainless steel base with reinforced stand (5.12" diameter × 2.64" width × 13.66" height) for exceptional stability on various kitchen surfaces. Compatible with multiple heat sources: included adjustable-flame alcohol burner (fuel sold separately), standard gas stovetops (natural gas/propane), and optional halogen heaters for precision temperature control ±1°C—ideal for different kitchen setups and brewing preferences.
• ADVANCED SAFETY SYSTEM WITH PATENTED BUFFER TECHNOLOGY Adjustable buffer connection clamp: The patented silicone buffer design enables precise adjustment of the tightness (with a compression range of 5 millimeters), which helps absorb thermal expansion pressure, prevent glass from sliding and breaking accidentally. Ergonomic Non-Slip Heat-Resistant Handle: Human-engineered grip with dual-layer insulation keeps hands safely 2.5" away from hot surfaces up to 180°C/356°F.
• VACUUM SIPHON TECHNOLOGY FOR PROFESSIONAL-LEVEL COFFEE EXTRACTION Utilizes scientifically-proven vacuum siphon principles to precisely control water temperature (±1°C accuracy) and pressure balance, fully releasing aromatic compounds and essential oils from coffee grounds. Produces a pure, clean, and bitter-free cup with enhanced flavor clarity and depth—capturing the authentic essence of specialty coffee beans without the acidity of traditional brewing methods.
