Porvair Ultravap Gemini
The Ultravap Gemini from Porvair Sciences is a dual-position nitrogen blowdown evaporator designed for laboratories requiring increased throughput and versatility in sample preparation. Supporting simultaneous evaporation of two microplates or vial/tube holders, the Gemini enables parallel processing of different sample formats, significantly improving efficiency compared to single-head systems. Each position is independently controlled, with dedicated temperature and gas flow settings, allowing precise optimisation for varying solvent types and evaporation conditions.
Designed for compatibility with all ANSI/SLAS standard plates and vial holders, the Gemini accommodates a broad range of evaporator heads, including formats for 12, 24, 48, 96, and 384 samples. Installation requires only a gas supply and standard mains socket, while the compact, lightweight construction ensures easy integration within existing fume cupboard space. Whether used for drying down, concentrating, or solvent exchange, this robust system offers reliable performance for chromatographic and analytical workflows.
