Bubble Test Cell

The Bubble Test Cell has been designed for the every day testing of oilfield inhibitors on steel. It is suitable for standard Bubble test work or for LCM techniques that in addition to the average corrosion rate vs. time gives information pertaining to Localised Corrosion. The Cell is a Quickfit 1 litre reaction vessel with lid and clamp. Several ports are available in the lid for gas injection via a 7mm glass rod, an exhaust, inhibitor injection port with plug and a central chemical resistant three electrode probe. The probe is supplied with three electrodes, two of which are made from Hastalloy on a 3mm thread, whilst the working electrode, typically made from a mild steel, is on a 10mm 440UNC thread. The intention is to reduce costs in that only the working electrode needs to be replaced between tests, whilst the Hastalloy Auxiliary and Reference Electrodes only need to be cleaned. The probe is indented with letters A, R and W to assist an operator when attaching the electrodes.

Cathodic Disbondment Test Cell

The Cathodic Disbondment Test Cell has been designed for testing of coatings. It accommodates a 15cm x 10cm painted test panel, which can also easily be attached to rounded pipes, via silicone sealant. The cell is supplied with the reference electrode and platinised titanium auxiliary electrode.

Electrochemical Cell Kit

Simplified Electrochemical Cell Kit

The 1 Litre Quickfit type Electrochemical Cell is supplied with the following: Sealed 1 Litre Reaction Vessel; Platinum Band Type Auxiliary Electrode; Saturated Calomel Reference Electrode; 0-105°C Thermometer; Glass Tube; Exhaust and a two electrode probe. The retractable probe fits in the centre of the cell which accommodates two standard 4.5cm² screw on electrodes. The access hole in the centre of the cell which is normally used for the 2 electrode probe is supplied with an adaptor for fitting of other probe types to suit your requirements:

Noise Reduction Probe
Noise Reduction Probes can reduce mains signal polarisation of your test electrodes from as much as a few volts to just a few mV’s. The root cause of this problem is the different levels of mains pick up between the Reference Electrode and the Test Electrode. In a simple cell where the reference electrode is just a piece of metal immersed in the bulk test solution mains pick up is not generally a significant problem. The problem arises when the Reference Electrode is in its own separate solution. This is true for typical commercial Reference Electrodes and especially for any remote Reference Electrode connected to the cell via a salt bridge.
