GreenHouse Plus Parallel Synthesiser

The GreenHouse Plus provides 24 heated and stirred glass reactions with volumes from 0.5 ml to 7 ml. The combined reflux and additions head allows for convenient additions or withdrawals whilst maintaining an inert atmosphere.

GreenHouse Plus brings all the benefits in productivity of parallel synthesis at a fraction of the cost of automated systems. Holding 24 glass reaction tubes in a removable reaction block with the same footprint as a standard micro titer plate (MTP), the GreenHouse Plus facilitates rapid transfer of samples by multi-channel pipettor or robotic systems.

Key features

GreenHouse Plus Parallel Synthesiser
  1. Heated directly by the stirring hotplate with optional digital control and Pt1000 temperature sensor.

  2. Water-cooled aluminium reflux head with nickel condensing fingers provides efficient refluxing within individual glass reaction tubes.

  3. Combined reflux and additions head allowing for convenient additions or withdrawals whilst refluxing.

  4. Provides 24 heated and stirred glass reaction positions with a reaction volume of 0.5 to 7 ml.

  5. ‘V-Mag’ technology uses a vertically positioned stirring bar to maximise the uniformity of the stirring within each reaction tube.

  6. Fits on any Carousel Stirring Hotplate

  7. Carousel Stirring Hotplate offers higher temperature, more powerful stirring and digital control

  8. Utilises single rotating magnetic field of the hotplate stirrer to stir all 24 positions

  9. Round aluminium base transmits heat evenly to all positions. Compact size has small bench-top footprint and is easy to store.

  10. No electrical or moving parts ensures maintenance-free operation. Easy to operate and set up.

  11. Cylindrical glass gas enclosure provides visibility of all 24 reaction tubes with no need to lean into the fume hood

  12. Optional HDPE cooling reservoir for chilled reactions to -78 C using dry ice and acetone

Extremely robust, requiring little or no maintenance... the GreenHouse represents a low cost and reliable platform for parallel synthesis.The Dyson Perrins Laboratory, University of Oxford
easy visibility of tube contents

Easy viewing of tube contents

  • The GreenHouse reaction block holds up to 24 x 7 ml glass reaction tubes.
  • The cylindrical glass enclosure provides visibility of all 24 reaction tubes during synthesis and creates a gas tight chamber for inerting.
Stirring

Powerful, even stirring

  • The GreenHouse is designed to mount on a Carousel Stirring Hotplate (145 mm diameter top plate), utilising the single rotating magnetic field to vigorously stir individual PTFE magnetic stirring bars in each of the 24 glass reaction tubes.
  • Radleys ‘V-Mag’ technology uses a vertically positioned stirring bar to maximise the uniformity of the stirring within each reaction tube.
heating

Rapid, efficient heating

  • Locating onto the Carousel Stirring Hotplate, the GreenHouse Plus will simultaneously heat up to 24 reactions from ambient to 150 ˚C with an accuracy of ±0.5 ˚C.
  • The temperature can be controlled using the stirring hotplate’s integral digital control or for greater accuracy, via an optional Pt1000 temperature sensor. Simply insert the temperature sensor through the port in the lid, through the septa, into the aluminium base.
GreenHouse Inert Head

Efficient refluxing

  • The water-cooled reflux/inerting head has nickel condensing fingers which provide highly effective refluxing within all 24 individual glass reaction tubes; minimising solvent evaporation and loss.
  • Water circulates inside the reflux/inerting head creating a cooling zone within the upper part of each tube, where vapours cool and condense back into the reaction.
  • The solid nickel condensing fingers are effective because they insert directly into each reaction tube, maximising the cooling surface. Nickel also offers excellent resistance to aggressive vapours.
  • Quick-release water couplings with integral shut-off valves aid the connection of the water supply and minimise leaks.
GreenHouse Plus Parallel Synthesiser

Operate under an inert atmosphere

  • A neat inert gas system with one inlet/outlet for vacuum and inert gas, allows reactions to be performed under inert atmosphere. Also because there is no flow of gas through the glass chamber there is minimal evaporation of solvents during synthesis.
  • A nickel plated safety relief valve prevents over-pressure during synthesis.
  • The reflux/inerting head accepts replaceable septum mats which allow the addition of retrieval of reagents from individual reaction tubes whilst under reflux/inert conditions.
GreenHouse Plus Parallel Synthesiser

Lightweight and compact

  • The GreenHouse’s lightweight and compact design may be easily lifted on or off the stirrer, and is easily rotated for all-round visibility and access to all tubes without leaning into your fume cupboard.
  • The GreenHouse’s compact footprint takes up less space in the fume cupboard and is easy to store after use.
  • Its contoured exterior is easy to clean, with an all over nickel plating for superior chemical resistance.
  • The GreenHouse offers virtually maintenance free operation – free of electrical or moving parts, and is easy to operate and set-up.
Cooled GreenHouse Plus Parallel Synthesiser

GreenHouse Plus Cooling Reservoir

  • Reactions to -78 °C are achieved using the optional cooling reservoir filled with acetone and dry ice (or other solvent and dry ice combinations)
  • The reservoir fits between the stirring hotplate and GreenHouse Plus assembly, allowing simultaneous stirring and cooling
  • The reservoir features a recess in the base that locates snugly around the top of the stirrer top plate and corresponding moulded lugs in the reservoir to hold the GreenHouse
Cooled GreenHouse bowl

GreenHouse Plus Cooling Reservoir

  • Use of the Cooling Reservoir does not interfere with the magnetic field of the stirrer
  • The robust HDPE cooling reservoir is compatible with a wide range of freezing mixtures for manually controlled cooling from ambient to -78 °C
  • The reservoirs insulated foam core maintains low temperatures for long periods, whilst protecting the stirrer from freezing
