Activation furnance for electrochemical sensors
Read moreThe activation furnance is a device used for curing individual sensors of the AC1 type. At a defined temperature (up to 1000 °C) depending on the electrode and sensor materials. When the sensor is cured, the surface of the electrodes is cleaned from surface oxides and organic impurities, which results in regeneration of the sensor or its activation. In this way, for example, old sensors with immobilized enzyme layers can be cured for reuse – see example at the end ot the document.

CEc Calomel Electrode Conic
Read moreThe calomel electrode (CEc) is a reference electrode based on the reaction between elemental mercury and mercury(I) chloride.
The aqueous phase in contact with the mercury and the mercury(I) chloride (Hg2Cl2, “calomel”) is a saturated solution of potassium chloride in water. The electrode is linked via a porous frit to the solution in which the other electrode is immersed. This porous frit makes liquid junction.
Calomel electrode (CEc) is designed for measurements with thermostated cell TC4, TC5, TC6, TC9.

EA163 Potentiostat
Read more- Modular potentiostat
- 4 modes: potentiostat, galvanostat, ammeter and voltmeter
This modular potentiostat is perfect for cyclic voltammetry and electroanalytical chemistry, and can use two (working and counter), or three (working, auxiliary and reference) electrodes. It can also operate as a galvanostat, ZRA (zero resistance ammeter), and high impedance voltmeter. It must be used together with any e-corder model.
The bandwidth of the EA163 is 100 kHz and so it is suitable for use with the Z100 Electrochemical Impedance Analyzer.

EA164 QuadStat
Read more- Four-channel potentiostat 10mA to 200pA range
- Separate/common reference and auxiliary electrodes
- BiPotentiostat
- Ideal for amperometric biosensors, microbial fuel cells, photovoltaic materials and neurochemistry
The QuadStat is a software-controlled four-channel potentiostat with many Research Advantages (see below). Each channel can be used as a single three-electrode potentiostat. Alternatively two (bipotentiostat), three, or four working electrodes can be used in a single reaction chamber with a common reference and auxiliary electrode. Potential at each working electrode can be independently adjusted between ±2.5 V, or by using an external waveform generator to between ±10 V. The QuadStat can measure currents from pico- to milliamperes, making it ideal for amperometric biosensor research including use as a multichannel monitor for in vivo nitric oxide or dissolved oxgen sensors.
Two QuadStats can be ‘piggybacked’ to provide eight potentiostat channels.
By connecting the corresponding auxiliary and reference electrode leads, the QuadStat can be used as a four channel two-electrode (working and counter electrode) potentiostat. There is also a zero resistance ammeter (ZRA) mode of operation on each channel.

EA362 Dual PicoStat
Read more- High sensitivity 2 channel potentiostat
- Bipotentiostat and 4-electrode modes of operation
The Dual PicoStat is a two channel high sensitivity potentiostat suitable for use with carbon fiber and ultramicroelectrodes for the monitoring of low current signals (down to picoameperes). It is commonly used for in vivo monitoring of dopamine by amperometry.
There are two potentiostat channels which enable the unit to also be used as a bipotentiostat (two working electrodes with a common reference and auxiliary electrode) so that dopamine levels can be monitored at two separate locations. Alternatively it can be used to perform duplicate experiments with separate samples, each with a working, reference and auxiliary electrode.
It can also be used as a 4-electrode voltage clamp (with two current passing and two voltage sensing reference electrodes) for studies of ionic transport across membranes or immiscible interfaces.
The Dual PicoStat is electrically isolated and is resistant to interference from neural stimulators, and ground loops. It is DC powered and can be used inside Faraday cages if required.
