Reaction
Block Synthesis System
| An inexpensive method
to heat, cool, reflux parallel reactions in disposable vials |
|
|
Heat - Cool -
Reflux
& Stir 96 reactions simultaneously!
|
- Temperature homogeneity of +/- 1 degree C
- Change from one size reaction block to another
in 30 seconds

Reaction Block Hall of Fame
|
| Designed to meet the
demanding needs of high-throughput research from parallel synthesis
to materials science. J-KEM's Reaction Blocks provide accurate
heating and cooling plus the convenience of being able to use any
size or style reaction block with the same shaker and digital
temperature controller. Can be used without a shaker as a dry
bath. |
| Four Styles of Blocks

Heated Reaction Blocks
 |
|
Reaction blocks have internal
electric heaters for homogeneous, fast and efficient heating.
All blocks are permanently attached to quick mount shaker
mounting plates.

Heated & Cooled
Reaction Blocks
 |
|
Heated and Cooled Reaction
blocks have the same internal electric heater as heated
reaction blocks, plus the addition of an internal milled
liquid flow path that surrounds every vial position. Cooling
is provided by circulating chilled liquids through the block
by means of a re-circulating chiller or using liquid nitrogen.
All blocks are permanently attached to quick mount shaker
mounting plates.

Reflux Reaction Blocks
 |
|
Reflux Reaction blocks
consist of a heated bottom layer, a cooled top layer and an
insulated middle layer. This configuration allows refluxing in
capped vials without pressure build up. Heating is provided by
an internal electric heater and cooling by internally milled
coolant channels. Cooling channels (optional) can be added to
the bottom heated layer to allow heating, cooling and
refluxing in the same block.

Multi-Temperature Zone
Reaction Blocks
 |
|
Build your own
system with 2, 4, or 6 independently thermostated reaction
blocks mounted to a single shaker mounting plate. Choose vial
size and reaction block style (Heated, Cooled, or Reflux) for
each reaction block position.
|
|
 |
Evaporate the solvent from all reaction vials at
one time.
Reaction block evaporators fit on top of a reaction block and
direct a jet of nitrogen gas into each individual vial. By gently
heating and stirring the reaction block (using its built-in heater
and bench top shaker), reaction solvent can be evaporated in a
fraction of the time required by other methods. Reaction block
evaporators are not backward compatible with older reaction blocks.
To modify existing reaction blocks, contact J-KEM for assistance.
A single evaporator fits multiple reaction
block sizes.
