ZP expands UK facility

In this video we do a quick walk through of our expansion within the UK.
If you have any questions of ZP please don’t hesitate to contact us.

Calibrating an ion-selective electrode

This week we have been working on calibration strategies for ion-selective electrodes.

ZP range of ion-selective electrodes

At ZP we are always pushing forward and so in this quick note we have done an inventory check to see what our current range of ion selective electrodes are. A great effort by the team as we are now on six, including: pH, sodium, potassium, ammonium, chloride and calcium. Please visit our website to find out more.

Trays of sensors and biosensors

At ZP we and many of our clients are scaling up and the days of testing one sensor or electrode at a time are a distant memory. In order to manually handle sensors we have developed these convenient trays so that sensors and screen printed electrodes can be moved quickly from test stations to functionalization stations.

At ZP we have one of the world’s largest ranges of biosensors and IVDs so if you have any questions regarding our products and services please don’t hesitate to contact us.

Biosensor into battery

At ZP we are focused on the production of screen printed electrodes (SPE) and electrochemical sensors and biosensors. This week whilst developing an assay we realised that the solutions we were using were in fact turning our SPE into a battery. In the adjacent image you can’t see the CV for phosphate buffer solution (PBS) because it is very small, but as soon as we add organic solvents such as DMSO, acetonitrile or ethanol we get a large increase in currents, approximately 0.05 mA. Our interpretation of the data is that the organic solvents are faciliatating the intercalation of anions into the carbon when we apply a positive voltage, and when we apply a negative voltage the anions are ejected and the electrode effectively discharges.

At ZP we manufacture standard products and we provide contract development and manufacturing to our clients.

If you are curious which carbon electrode was used in the data please visit our website.

Packing biosensors

At ZP we know it’s not enough to manufacture a biosensor, you also have to pack it appropriately.

Please see the video below on how we pack and protect our biosensors.

Heavy Metal Detection: Zn, Cd, Pb, As, Cu

At ZP we have electrochemistry and electrochemical sensors at our core, and so we are delighted to help people in the development of sensors for heavy metals, including: zinc, cadmium, lead, arsenic and copper.

At ZP we have experience in the production of disposable sensors for heavy metal detection. Please don’t hesitate to contact us to find out more.
