- why vapourtec
Vapourtec offer a range of pumping modules, depending on the features required.
Based on the Knauer HPLC pump, the Vapourtec pumping module offers several key features.
HPLC pumps are accurate, reliable and offer a large range of flow rates in a single pump without needing to change any parts. However, failure to wet the pump fully (perhaps when switching between immiscible solvents) or outgassing from reagents may cause small bubbles to firm inside the pump. With no visible warning, output flow would no longer be accurate.
The Vapourtec system takes care of that.

The Knauer HPLC pump offers precise flow, with flow rates from 0.010 to 9.99 ml/min .
The standard pump module offers reaction pressures up to 42 bar.
- Acid resistant
As an option Vapourtec offer the strong acid resistant R2C module. Though based on the Knauer pumps, the acid resistant pump system features some specially developed components.
This can be used to pump (for example) fuming nitric acid or concentrated sulphuric acid, and has been in use in industry doing exactly that since 2009.
All of the required tubing fittings and back pressure regulators to operate a fully acid resiatant system are included.

- High Pressure
For certain applications higher pressures may be required. This pump module features all stainless tubing and manifold, and offwers pressures up to 200bar.
A system with two pump modules can mix high pressure and standard types.
An acid resistant version of this module is not available.

Expandable up to 4 pumps
The Vapourtec system offers fully integrated control of 1 or 2 pump modules, meaning the system can have up to 4 pumps.
The FlowCommanderTM software integrates all 4 pumps ensuring reagent peak matching in even the most complex reactor layouts.

Different Pump Module Options
The different pump options available can be seen below.
A system can include a 2 channel module plus (optionally) another one or two channel module, meaning 2, 3 or 4 channels in total.
|Number of channels||Sample Injection Loops||Strong acid resistance||Max Reaction Pressure|
|R1 Plus||1||Yes||No||42 bar|
|R1 C||1||No||Yes||42 bar|
|R1 C Plus||1||Yes||Yes||42 bar|
|R1 HP||1||No||No||200 bar|
|R1 HP Plus||1||Yes||No||200 bar|
|R2 Plus||2||Yes||No||42 bar|
|R2 C||2||No||Yes||42 bar|
|R2 C Plus||2||Yes||Yes||42 bar|
|R2 HP||2||No||No||200 bar|
|R2 HP Plus||2||Yes||No||200 bar|
|Q||Does the acid resistant system have a lower upper pressure limit than the standard system ?|
|A||No, it has the same maximum as the standard system. There are no compromises if you choose acid reistance|
|Q||Can I specify 2 x R1 instead of 1 x R2 ?|
|A||Put simply, there is no good reason to do this. It would be no cheaper, have twice the footprint, and would limit future expansion possibilities|
|Q||Can I upgrade to acid resistance or sample injection loops later ?|
|A||Sample injection loops, no. Acid resistance yes but it will involve an on site visit or a return to base, both of which would be more costly than specifying the acid resistance at initial order time.|
|Q||Can I mix pump module types in one system ?|
|A||Yes, but note that the first (primary) module must have 2 pumps|
