Precision laser cut funnel and shelf - The funnel and shelf are precisely laser cut for high quality construction and accurate fit in every detail. Ball valve options - Choose between a durable stainless steel ball valve or a PVC ball valve. Both options have a 27 mm output diameter for consistent and controllable flow. Adjustable height bracket - The included bracket can be easily adjusted to different container sizes, ensuring a secure and perfect fit each time. Versatile use - For liquids: keep the ball valve in place to control and regulate flow. - For particles: remove the ball valve to maximize throughput and handle particulates efficiently. Use scenarios - Liquid transfer in labs or workshops: connect to standard containers and use the valve to prevent spills and control pouring. - Beverage preparation or home brewing: pour from carboys or containers with precise flow control. - Powder or particulate transfer: remove the valve to allow unrestricted flow and higher throughput.
