Screen-Printed Platinum Electrodes
Disposable Screen-Printed Platinum electrodes. Suitable for working with microvolumes (ref. 550 and ref. 550BT) or by dipping them in solution (ref. C550). Electrodes screen-printed with high (refs. 550 and C550) and low (ref. 550BT) temperature curing inks which may have different properties depending on the application.These references are ideal for decentralized assays or to develop specific (bio)sensors, as well as electrosynthesis and compounds characterization. Useful for undergraduate lab to avoid tedious polishing of solid electrodes.
Ceramic substrate: L33 x W10 x H0.5 mm Electric contacts: Silver
The electrochemical cell consists on: Working electrode: Platinum (4 mm diameter) high or low temperature curing ink. Auxiliary electrode: Platinum high or low temperature curing ink. Reference electrode: Silver
Screen-Printed Platinum Electrodes are commercialised in 75 units packs. They should be stored at room temperature, protected from light in a dry place.

DropSens Screen-Printed Platinum Electrodes exhibit a high electrochemical activity and good repeatability. An example is observed for the K3[Fe(CN)6] electrochemical process with 5 different ref. 550; RSD = 2.6%.
Also, specific connectors that act as an interface between the screen-printed electrode and any potentiostat (refs. DSC, CAC) and other accessories are available at DropSens.
