Manufacturer: Bürkle Model: Gas-tight stainless steel barrel pump discharge hose/stopcock P/N: 5611- (more)1090 Description: Gas-tight barrel pump is a pump with flexible discharge hose for filling off into large canisters and containers. It provides convenient transfer because the canister can stay on the floor. The connection cone is held onto the container. The gas-tight barrel pump enables odour-free transfer. During transfer with normal pumps, it is impossible to prevent vapours escaping into the atmosphere. The gas-shuttle method avoids this. Any vapours produced are returned from the container which is to be filled to the original container via the gas-shuttle pipe. The gas pipe and the liquid pipe are additionally provided with stopcocks. Gas-tight pumps are used for substances that have a strong smell such as ammonia. Not suitable for acetone!Please note: When withdrawing flammable liquids, the barrel and pump has to be grounded! Use Anti-static set!Features: - Parts in contact with media: Stainless steel AISI 304 (1.4301), PTFE, nickel-plated brass, PA that can conduct electricity- Incl. gas-tight barrel screw joints with 2" fine thread- For bottle openings from 16–49 mm- Immersion tube Ø 32 mm- The pump can be hermetically sealed with two ball valves Specifications: - Immersion depth: 57 cm- Total length: 69 cm- Pump capacity: 350 ml per stroke Items delivered: - Bürkle Gas-tight stainless steel barrel pump discharge hose/stopcock Condition: The pump is in excellent like new cosmetic condition. It is 100% functional tested and ready to be used.

VACUUBRAND PC 510 Select Chemistry Pumping Unit Ultimate Vacuum 7 mbar (5 Torr) Maximum Pumping Spe (more)ed 1.4 CFM at 60Hz Number of Heads/Stages 2/2 Features - VACUU·SELECT vacuum controller with graphical user interface simplifies work in the laboratory - Predefined applications save time and give reproducible results - Easy-to-use application editor allows own process sequences - Powerful vacuum pump with excellent chemical and condensate compatibility - Excellent environmental friendliness due to efficient solvent recovery Our PC 500-series chemistry pumping units of this series are an excellent choice for supporting electronically controlled evaporation or drying processes. Our popular MZ 2C NT two stage chemistry diaphragm pump is the heart of these pumping units, frequently used for medium-sized vacuum applications involving common solvents. The integrated VACUU·SELECT controller provides an easy-to-use, application based interface that covers all common lab applications. The VACUU·SELECT controller has you covered. Use manual set-point-control for simple processes, run distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, it detects the boiling pressure and switches to two point control to hold pressure steady when a boiling point is detected. The inlet separator, made of glass with a robust protective coating, prevents particles and liquid droplets from entering the pump, preventing damage and extending pump life. And the exhaust vapor condenser allows for nearly complete recovery of solvents when used with a chilled water line or recirculating chiller for economical recycling and environmental protection.INCLUDED: The VACUUBRAND PC 510 Select Chemistry Pumping Unit includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
