MOST ECONOMICAL STEM REACTOR: STEM RS900 Reaction Station Features

10 position heated and stirred reaction stations with removable cooling reflux modules and inert gas cover:

• 10 positions x 25mm diameter

• Microprocessor temperature control with LED display to 1°C.

• Heated Units: ambient +5°C to 150°C, with temperature stability +/- 0.5°C.

• Microprocessor controlled stirring from 400rpm to 2000rpm, with a magnetic stirring bar for each position. Provides excellent magnetic coupling for stirring even the most viscous samples.

• Features adjustable stirring ramp/soft start to ensure stirrer bar coupling.

• Safety temperature cut-out eliminates runaway conditions.

• Standard wells are 40mm deep (with other depths available on request).

• Standard wells are 25mm diameter. With reducing sleeves/adaptors for 16mm, 20mm and 24mm diameter tubes available as standard, (other reducing)

• sleeve/adaptor sizes available on request).

• Block is Teflon coated

• Optional Temperature probe

Forced Air and Water Cooled Reflux Modules
Optional forced air or water cooled reflux modules, which mount directly on top of the Reaction Stations to form a cooled environment for the unheated section of the tube and reduces solvent loss due to evaporation.

Inert Reactions
Both style of reflux module feature an integral hinged lid with holes corresponding to each reaction position. The holes are covered by a replaceable silicone membrane, which can be pierced by autosampler needles for automatic reagent addition under an inert atmosphere.

Safety First
The well insulated design of all STEM Reaction Stations ensures that the outer casing is always cool-to-the-touch, whilst a thermal cut-out eliminates runaway conditions. The integral heating block in coated in Teflon to protect from chemical splashes.
