The Vapourtec V-3 pump – A breakthrough for flow chemistry
The development of the V-3 pump has enabled the creation of the new E-Series flow chemistry system. The V-3 is robust, very simple to use and can pump:
- Strong acids, including fuming nitric acid
- Organometallic reagents
- Light slurries and suspensions
- Operation as an active pressure controller
At the heart of the R2-S pump module is Vapourtec’s V-3 precision peristaltic pump. It’s capable of…
- Pumping at 10 bar, with flow rates from 0.02 ml/min to 10.0 ml/min
- Handling strong acids, bases and organometallic reagents, as well as a range of gases
- Generating smooth output flow across the full pressure range
A traditional peristaltic pump would be unsuitable for flow chemistry because…
- It would not withstand the range of solvents and reagents required for chemical synthesis
- It could not generate sufficient pressure
- The output would not be smooth, constant flow rate
The Vapourtec V-3 features advanced control for smooth output
The tube materials are specially developed in collaboration with a major global fluoropolymer manufacturer, resulting in a pump which can generate high pressures and is compatible with synthesis solvents, acids and bases.
A standard peristaltic pump runs at a steady rotational speed whereas the V-3 does not.
The exact rotational speed profile is complex and is a patented function of the flow rate, rotor position and pressure. The result of that behind the scenes complexity is total simplicity for the user.
The V-3 pump can be used as an active back pressure regulator (BPR)
Simply reconfigure the fluid connections to one of the pumps and select (BPR) from the SETUP menu and the selected pump can be used to control pressure in the reactor system.
Simple to use
The Vapourtec V-3 is extremely straightforward to use because:
- It will self prime at the start of the day with the push of a button
- The lack of any valves or sliding seals means that it pumps suspensions (or solutions that generate particulates while being pumped) and can pump moisture sensitive reagents without exposing any wetted parts to air during the pump cycle
- It can pump two consecutive solvents even if they are not miscible
- It’s easily dried when necessary
- A low internal pump volume means rapid switching from solvent to reagent with minimal waste or dilution effects
- It pumps air or other gases
The upshot of this is that the time to start an experiment from scratch is greatly reduced, making the system perfect for “taking a quick look” at a reaction.
