To all radiochemists: Do you still dry your 18F manually via azeotropic desitllation? Check out our drying module which can be build (3D print) for under 1000 €. @uni_tue @MenzelFlo @jonny_cotton @maur3ra @thezieglergroup

@maur3ra @MenzelFlo Congratulation, @MenzelFlo 🥳

[Jochen Neumaier @JochenNeumaier]

@PieberLab @amieramadani Herzlichen Glückwunsch, Amiera!

@MedChemDan I have printed some more reactors (at 420, 450 and 480 °C, all leakproof). If you DM me your postal address, I can send them to you for testing....@KLchemistry @MedChemDan @Lees_tweeted

[Jochen Neumaier @JochenNeumaier]

@nik0tron @uni_tue @klchem @Lees_tweeted @prusament It is Fiberlogy PETG Burgundy Transparent.

[Jochen Neumaier @JochenNeumaier]

We 3D printed PEEK reactors at 420 °C instead of 480 °C and performed pressure tests with our FOMSy system up to 8 bar, still leakproof😀.

With a printing temperature of 420 °C, an inexpensive printer such as the Creatbot F160 PEEK (~2300€) could be used. Does anyone have experience with this printer?

The Collection of Bespoke Laboratory Equipment (COBLE) is accepted with minor revisions in #AppsPlantSci which means I can finally post our designs! Want to #3Dprint your own lab equipment? Download the designs and step-by-step instructions here! https://t.co/A7TGFunaVA

Our latest paper: new biomimetic flow fields for electrochemical microreactors via #3Dprinting.🧪⚡️ Thanks @inmagarlop for sharing this methodology.🍃🧠 A @TUC_research - @unicomplutense collaboration.👩‍🎓#Electrochemistry #FlowChemistry Link: https://t.co/zuWpa1kRuc📄

[Jochen Neumaier @JochenNeumaier]

@KLchemistry @MedChemDan I can print some PEEK reactors as research samples for you. If the demand doesn't become too high, it's no problem.

[Jochen Neumaier @JochenNeumaier]

Our publication on 3d-printed PEEK microreactors is now open source and available to all! A very good combination with FOMSy (see my last tweet).

@NickelCarbon @V_Saggiomo @MenzelFlo @maur3ra @jonny_cotton @uni_tue @WSIC_Tuebingen we use a standard analytical 6 way valve, e.g. Rheodyne 7725 or 7125 with injection port, but any other 6 way valve should also work.

@Chagas_AM @Prometheus_sci @MenzelFlo @uni_tue @thezieglergroup It is still under development, early next year it should be finished...

[Jochen Neumaier @JochenNeumaier]

Upgrade to our 3D-printed dual syringe pump: Two optional pressure sensors with automatic shutdown function for each syringe. #flowchemistry #openhardware @MenzelFlo @uni_tue @thezieglergroup

[Jochen Neumaier @JochenNeumaier]

Before we publish it, we want to implement some optional features to upgrade the pump. You need to be a little patient...

[Jochen Neumaier @JochenNeumaier]

First real test of our new, completely 3D-printed, geared syringe pump. It will be published asap #flowchemistry #openhardware @MenzelFlo @thezieglergroup

[Jochen Neumaier @JochenNeumaier]

Our first paper about 3D-printed PEEK reactors is now published in Reaction Chemistry & Engineering! Congrats to Florian Menzel and Thomas Klein and @thezieglergroup. @uni_tue
