R-Series Reactors

 The Vapourtec R-Series platform permits up to 4 reactors of various types to be used together in any configuration, and controls the temperature of each reaction step independently.   Scroll down to see the range of different reactors available.

 

 

The Vapourtec Forced Convection Heating and Cooling system

Vapourtec uses a unique method of controlling reactor temperature.

The reactor coil or column is housed inside an insulated  glass manifold, inside which heated or cooled is circulated. 

Up to 4 of these can be clicked onto a single R4 reaction heater.

Coil tube reactors, therefore, do not need to be wound tightly round any sort of former to achieve thermal conductivity, so as a result have little or no physical stress and are also kept at a uniform temperature with no hotspots.  This results in more precise control of reaction temperature and long reactor life.

Reactors can be switched in seconds with no tools.

 Reactor manifolds can be changed in seconds

The advantages of the Vapourtec temperature control system are manyfold

  • Temperature is measured at the reactor wall so control is extremely accurate.
  • Because of the low thermal inertia, the systems moves between temperature setpoints extremely quickly
  • For PFA reactors and glass columns, the reaction is fully visible at all times.  (With temperatures above 150oC, however, stainless steel reactors are used)

Gas / Liquid Reactor

  •  Allows gas to be supplied to a reaction as it is proceeding (rather than pre-dissolved before the main reactor).  This permits hydrogenations at 1M, for example.
  • Proven for O2, CO, H2 , more gases currently being tested.
  • Reaction temperatures up to 150oC
  • Compatible with all existing Vapourtec systems
  • Simple gas management (pressure rather than mass flow control)
  • Up to 4 reactors can be used in series for increased throughput

FAQ

 

Q What is the maximum volume reactor available
A With PFA tube reactors, it is possible to have a total of 4 x 10ml = 40ml for a single reaction stage.  With stainless steel, however , it is possible to have a total of 4 x 25ml = 100ml.
   
Q Can I wind my own reactor coils
A No.  Vapourtec insist on fully testing all new reactors at elevated temperature and pressure as part opf the manufacture process.  However, see next question.
   
Q How many cycles will a reactor last ?

A		 Vapourtec reactors are not consumable items.  They can be (and usually are) used for years without replacement.   Replacement reactors are only required if a reactor become irretrievably blocked by precipitation.
