Accessories for efficient synthesis screening and reaction setup
There are small and simple things that make the difference.
Use the possibilities to simplify your daily laboratory work for a more productive, safer and more sustainable chemistry. Developed from chemists for chemists.
Reaction Vessels & Adapter
Vessel that fit to your reaction
Select the vessels from the product portfolio that are suitable for your reaction. The volume range is from a few 100µl up to 30 ml. For special applications there is the water separator, the GL 32 vial made of PTFE or made of light protective glass
Customized Adapter
Syntheses directly in NMR tubes under reflux or in 8 mm tubes at variable temperatures?
No problem with our special adapters for reaction screening.
Do you need to use your existing reaction vessels?
– with customized tailor-made adapters we make the xelsius exactly suitable for this.
Glass vials with GL 25 thread
Proven Duran glass with standard laboratory GL 25 thread enables universal use in daily laboratory routine. The vials are optimized in dimensions and with a thin wall thickness to allow rapid heat transfer into the reaction solution.
Available as HV vial (High Volume) with 24 mm outer diameter for reaction volumes up to 30 ml and as LV vial (Low Volume) with 13 mm outer diameter for reaction volumes from 0.5ml to 4 ml.
PTFE Vial – 100% anti-stick
With the PTFE vial you benefit from the advantages of PTFE from -50°C to 220 °C.
Equipped with GL 32 and an ultra-thin smooth wall for optimal heat transfer and easy handling it is ideal, especially if glass is not the right material for your reaction conditions.
Water Separator Vessel
In many chemical reactions it is important to remove water from the reaction mixture.
The combination of water separator and reflux condenser enable efficient work.
Reaction-Setup & Monitoring
Whether you want to optimize hydrogenations, stability studies, reaction kinetics, catalysis studies or a typical synthesis – you always need simple and flexible handling and full control and reproducible reaction conditions. With the xelsius Reaction Station and suitable accessories, you are optimally equipped for this.
An all-rounder for your reaction setup – our 5-Port Reaction Cap
Flexible and useful as a 5-port flask for small reactors. Ideal for:
- Connection of a PT 1000 temperature probe for monitoring the reaction temperature
- Dosing and sampling of reagents via 1/8″ or 1/16″ PTFE/PFA Tubes
- Sampling options via tube fittings and Luer syringe connection
- Process gas and inert gas connection via tube fittings
- connection of a 2/2 way valve made of PTFE/PEEK
- Needle access via an N9 septum port
- Access for probes up to 4 mm OD
Sampling & Fittings
The sampling options are as diverse as your experiments. With the needle/septum port or with ¼” UNF 28 fittings and the appropriate Luer tubes, nearly all possibilities are available for you.
Reaction Monitoring
No reaction control without temperature control.
The xelsius has reaction temperature measurement and monitoring “on board” as standard for each of the 10 reaction cells.
With the 5-Port-Reaction cap and the PTFE coated PT 1000 temperature probe you have full control of what is going on in your reaction vessel.
One more click at the end of the experiment takes care of all the necessary documentation.
Reflux Condenser
Working under reflux – unimpressive but effective
Simply click in and you work under reflux conditions, save time, solvent and costs.
No solvent loss, even with long reaction times at high temperatures.
Automated Dosing
Reaction automation with the Dispensing Unit
The Dispensing Unit turns the xelsius into an automated reaction station with up to 10 independent reactor cells.
Time controlled and precise dispensing of reagents and solvents
- with two independent channels from 20µl/min up to 4 ml/min.
- Dosing amount, dosing speed and timer functions can be programmed individually for each reaction cell.
Inerting & Gas Injection
Working reproducible under inert conditions
Many catalyst induced reactions are sensitive to oxygen and humidity. With the Inert Workstation, 10 reaction vessels can be evacuated in parallel and purged with inert gas in a very efficient, highly reproducible manner.
This leads to syntheses with improved reproducibility and high conversion rates.
Gas Balloon Supply Set – simple and clever working with reaction gases
Injection of reaction gases for example in hydrogen reactions with the Gas-Balloon Supply Set
Magnetic stirrer
Stirred and not shaken
PTFE-coated, chemically inert magnetic stir bars, optimized and adapted to High-Volume vials and Low-Volume vials, tailored to your application.
