Synple 2

The small and compact capsule-based synthesizer for the generation of research products, works in an analogous manner to a capsule coffee maker. Simply add the starting material to be transformed and a commercially available, single-use, disposable reagent capsule and with a single touch of a button, the product is generated, isolated and purified!
Following the generation of the desired product, an automated washing sequence allows the machine to be used directly by another user without risk of contamination. With all the chemicals and solvents required for the transformation, as well as the waste generated, the risk of user exposure is drastically reduced. Thus this technology offers not only time-saving, productivity, and efficiency benefits, but it offers a far safer process than the respective traditional synthetic procedure.

The 3 in 1 solution offers an unprecedented combination of hardware, software and an optimized chemical process. Use of the automated synthesizer, in conjunction with the specialised capsules, offers the opportunity to break free of the limitations imposed by traditional synthesis, and the benefits of a safe, time-efficient, cost effective, plug and play synthetic procedure.

Advantages of Synple


5x more efficient

Much less working time is required to generate new molecules. The synthesizer will only take 5-10 minutes to set up and will run completely autonomously. This offers the potential to increase the productivity of every synthetic chemist, whatever level of skill and experience.

No training required - Easy to use

The plug&play device is intuitive to use and requires no special training. No detailed chemistry knowledge is necessary to create new molecules.


70% Lower costs

Compared to carrying out a reaction manually, the synthesizer can cut down on 70% of the costs to generate one molecule.


High Safety

The automatic reactor is fully enclosed, thus the user has no exposure to any chemicals used during the synthetic process. This complies with newest laboratory safety standards.


Small footprint

With only 25 x 35 cm footprint, the synthesizer uses only a minimum amount of space and fits in every laboratory.

90% less waste

The fully optimized reaction sequence uses only a minimum amount of reagents and solvents, therefore reducing overall waste.

Frequently asked questions (FAQ)

Who is Synple Chem?

Synple Chem was founded in 2016 as a Spin-off from ETH Zürich. Our mission is to provide easy to use, safe, efficiency-enhancing solutions that represent the future of organic synthesis. 

How many products are on the market?

Now, alongside the Synple 1 and 2, we have our latest addition - the Synple Unity, a flexible parallel synthesiser.

Can I put my own materials in the cartridges?

No, the cartridges come ready filled with all the reagents and materials required for the reaction, work-up and purification. We can, however, provide custom cartridges for users under certain circumstances.

What solvents are compatible with the machine?

The machine itself is tolerant of almost all solvents. The limitation are only related to what is tolerated in terms of the chemistry by each reaction class. More information can be found in our application notes.

How does the machine handle poorly soluble starting materials?

In many cases, co-solvents can be added to help solubiulise poorly soluble starting materials. 

How are lower reacting starting materials handled?

We provide a scope for each reaction that indicates what is fast reacting and slow reacting. For slower reacting materials we recommend increasing the default reaction time. 

Can I run more than one reaction at the same time?

With the Synple 1 and Synple 2, only one reaction can be run at a time. The Synple Unity system allows you to build a parallel synthesis system to suit your own needs.

How much maintenance is required?

The machine requires very little maintenance and most of the components, e.g. the lines, connections, vial, are all standard. We are also able to offer service and maintenance contracts.

Do you have products on the market?

Yes! Our Synple 1 machines have been installed with customers since May 2018 and our new Synple 2s have been in use since October 2019.

In which countries is Synple available?

At the moment we sell directly across Europe and the UK. We can also sell direct in the US or alternatively use a distributor. In addition, we are in discussions with several distributors across Asia.

What is the lead time for the machine and cartridges?

The average lead time for the machine is four weeks. Cartridges can be delivered within the week.

Can my starting material be dissolved in a broad range of solvents?

This depends on the reaction class and what is tolerated by each particular reaction. In many cases co-solvents can be used to help solubilise the starting material.

Does the machine allow for reaction monitoring?

Each method has been pre-optimised to give the best yield and purity across a broad substrate scope. If optimisation is required then we would recommend skipping the purification step and checking the product at the end of the run. If it has not gone to completion, the reaction can be run again.

Can the machine be connected to analytical or purification systems?

This is something we are actively exploring.

How long does a run take?

This is dependant on the reaction class. Each run time includes the reaction, work-up and purification time.

Testimonials from Synple Users

We are working with the Synple instrument in our laboratory for several months now
The first reaction tested was the one using SnAP reagents. The interest of this reaction developed by Professor BODE to form original saturated heterocycles was presented to us at a medicinal chemistry symposium a few years ago.
We then purchased the corresponding SnAP reagents sold by Aldrich and tested them under conventional laboratory conditions with original aldehydes and ketones. Although the results were satisfactory, the perspective of using potentially toxic products such as tin derivatives was not very encouraging. This very simple to use synthesizer has not only avoided handling these reagents but also improved the efficiency of the reaction by leading to often clean products with good yields.
Applied to reductive amination reactions, the same technology has led to variable results, more or less satisfactory depending on the type of amines used (salified, primary or secondary).
Two very convincing tests were also carried out on the formation of PROTACs from aldehyde and appropriate pre-filled cartridge.
Ease of use, reproducibility of experiments and non-exposure to toxic chemical substances are the major assets of this new automated synthesizers, which should be developed in particular to support scale-up.

As a beta-tester I have successfully used Synple’s technology for all its existing applications. The N-heterocycle forming application is easy to use and I would much rather use this machine to do SnAP chemistry then do the reaction in a flask. The reductive aminations also work well and the PROTAC application is a great way forward for this technology!

The N-heterocycle forming application is easy to use and I would much rather use this machine to do SnAP chemistry then do the reaction in a flask

The machine is really very easy to use. This technology was not really part of our automation strategy but we have been surprised how quickly it was adopted.
We have had the Synple instrument in our labs for several months now. We like the instrument and it works perfectly well. We have found that anyone can get good results with the SnAP cartridges without first having to learn the insights of SnAP through painful failures. The same chemistry on the same scale was far better on the instrument than it was in the flask.
The reductive alkylation of secondary amines was successfully achieved using paraformaldehyde and small amine fragments, resulting in water soluble products. The instrument gave the product in good quantity and initial quality. Although the final products did need some further purification, our chemists struggled to reach the same level of quantity and purity when the reaction was performed in a flask.
In summary, the instrument really makes life easier and, especially if there were a way to scale up the reactions in a similarly easy way, then I wouldn’t want anyone in my organization to perform the SnAP and reductive alkylation reactions in the traditional way. Just adding the reagents and then pressing the button is so much easier and reproducible.
The machine is very easy to use and took no more than 10-15 minutes for us to do the whole process. Everyone who has used it thinks that it does increase their productivity. I personally made compounds that I would otherwise not have had the time to make
We consider the instrument very valuable to quickly make a set of PROTACs from scratch.
