This product line is no longer available through us.
The STEM Omni Reaction Stations enable you to conduct parallel synthesis for either 6 or 10 reactions simultaneously.
- They offer a modular design which enables you to build up your own parallel synthesis system in 5 steps, by ordering your choice of:
- The Omni Controller base unit remains the same for all Omni models, and one base unit can accommodate sample volumes from 2ml to 250ml.
- All heating blocks, glassware and reflux heads are interchangeable.
- The Omni Reaction Station footprint is compact and can be placed into any fume hood, or within a small bench space.
- You have a choice of either 10 or 6 positions within your Omni Reaction Station. 10 position units allow up to 10 reactions with working volumes of:
- Working volume Omni Model: 100 - 250ml OS6250.
- With the exception of different working volumes, all of the models within the Omni 1000 and 6000 series STEM Omni Reaction Stations offer the same outstanding performance features:
- Interchangeable, modular design.
- Stirring stability and speeds of 100 - 2000 rpm.
- Simple menus and touch pad interface to control the system performance.
- All heater cartridges are equipped with “in block heaters” that allow temperatures up to 220ºC.
- High level of stability (± 1.5ºC) across the heater cartridge itself.
- An external temperature probe to increase temperature accuracy to ±0.5ºC.
- A “cool to touch” outer casing.
- Selected cartridges can also be used in conjunction with a cooling plug to extend the operating temperature range from - 30ºC to 220ºC.

Omni Temperature Sensor.
- For fast and more precise temperature control, the temperature probe can be inserted either into a machined pocket in the reaction block or via a thermocouple pocket directly in one of the reaction vessels.
- The temperature sensor attaches directly into the Omni Controller.
Omni Gas-tight PTFE caps.
- By using a simple bi-directional open/close lever, each reaction vessel can be controlled separately.
- Each vessel cap has a septum to allow sampling at each vessel position.
Omni Reflux Head.
- Efficient condensing and refluxing, for samples up to 25ml, is provided through the use of a liquid-cooled aluminium reflux head. Cooing is introduced through the inlet/outlet ports.
- Individual reaction positions are numbered (1-10) for simplified tube and sample identification.
- A central gas inlet/outlet port, combined with the gas-tight PTFE caps allows for a vacuum to be pulled and/or inert gas (nitrogen) to be ported into each individual tube.
Omni Reaction Vessels.
- 24mm and 25mm x 150mm threaded glass reaction vessels which can handle volumes from 2 - 250ml.
- Solutions can be added and removed through the top of the reaction vessel.
Omni Cooling Plug.
- Allows the reaction unit to cool down to -30ºC, greatly expanding the types of chemistry you can perform with this equipment.
- The cooling plug is simple to use:
- Insert the cooling plug into the reaction unit and attach cooling lines to the inlet/outlet via quick disconnects.
- Melting ice is no longer a problem with the cooling plug.
Omni Heater Cartridge.
- Encased reaction unit ensures accurate temperature uniformity across the unit.
- Unique patented air flow through ventilation slots beneath and around the rim of the case ensures a cool case temperature, allowing it to be safe to touch.
- Used to control both temperature and stirring speed, the Omni Controller is easy to operate.
- Temperature and speed can be separately enabled to provide complete control of reactions.
- Both temperature and speed are individually adjustable by depressing the up/down keys on the interface.
- The control panel (on the controller) has 3 indicator lights: “Power On”, “Heater On” and “Stirrer On”, so that you can closely view the performance of your system.
- A 2 x 16 digit display indicates the actual temperature from -30C to 220ºC.
- Stirring speed is reflected by simply touching the stirrer speed knob.
