GreenHouse Plus Parallel Synthesiser
GreenHouse Plus Parallel Synthesiser
24 heated and stirred reactions from 0.5 ml to 7 ml, with refluxing and an inert atmosphere
The GreenHouse Plus allows for 24 heated and stirred 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 screening chemical reactions in parallel 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.
Choice of PTFE Stirring Paddles
- Powerful stirring and rapid heating to 150 ˚C
- 24 tube, micro titer plate footprint
- Reaction volumes from 0.5 ml to 7 ml
- Removable water cooled reflux head
- Perform reactions under an inert atmosphere
- Easy viewing of tube contents during experiments
- Nickel plated aluminium offers excellent chemical resistance
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.
Powerful, even stirring
- The GreenHouse is designed to mount on a Carousel Stirring Hotplate (135 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.
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.
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 minimises leaks.
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 an 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.
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.
