Welch ProBoost Air-Cooled Diffusion Pump

The Welch ProBoost is a high-performance, air-cooled diffusion pump designed to work in conjunction with a backing pump like the CRVpro to achieve deeper vacuum levels and higher flow rates, enhancing your vacuum system's capabilities. With its unique design, the ProBoost is an excellent solution for high vacuum applications such as Schlenk lines and processes requiring extreme low pressures for air-sensitive reactions.

Key Features:

• High Vacuum Performance: Achieves an ultimate vacuum pressure as low as 0.00002 torr, significantly deeper than what a 2-stage rotary vane pump can achieve alone.
• No Internal Moving Parts: The gas jet pump operates efficiently with no moving parts, lowering the chance of maintenance and enhancing reliability.
• Easy Attachment to Backing Pumps: Specifically designed for seamless integration with rotary vane pumps like the CRVpro, enhancing performance for high vacuum and Schlenk line setups.
• Air Cooled Diffusion Pump: Utilizes boiling silicone vapors directed through a hollow cone to generate the vacuum, ensuring consistent and efficient pumping action.
• Built-In Control Board: Automatically controls the fan and heater. When the ProBoost is powered on, both components activate; upon turning off, the heater switches off, and the fan continues to cool for 20 minutes.

The Welch ProBoost is essential for labs requiring high vacuum capabilities, especially for reactions involving air-sensitive compounds like organometallics, metal amides, and hydrides. It provides a robust solution when paired with a backing pump, optimizing your vacuum system for the most demanding applications.
