basic information

Pine RDE/RRDE electrodes can be utilized in various fields of research, including catalysts and corrosion for fuel cells. By combining Pine Research's rotating ring-disk electrodes with electrochemical measurement devices, parameters such as rotation speed can be remotely controlled from a computer. The Pine AFMSRCE rotating ring-disk electrode is the best-selling model in the world (with a total global sales of 3,000 units). It offers the widest variety of electrode types (materials) in the industry. There are diverse options available, including integrated electrode types, types that allow for chip replacement, and types that allow for insert replacement. It is also possible to repeatedly attach and detach preferred disk materials to the Pt, Au, and GC ring assemblies for RRDE measurements. We offer a variety of cost-effective combinations of bipotentiostats and rotating ring-disk electrode systems.

Applications/Examples of results

Pine RDE/RRDE electrodes can be utilized for oxygen reduction reactions (ORR) in fuel cells and corrosion research. The Pine AFMSRCE rotating ring disk electrode is the best-selling model in the world (with a total global sales of 3,000 units). Pine Research has two models of rotating ring disk electrode bodies: the typical model AFMSRCE and the compact model WaveVortex10 rotating ring disk electrode. The AFMSRCE is a long-selling product from Pine Research. By changing the rotating shaft, it can be adapted to a rotating disk electrode (RDE), a rotating ring disk electrode (RRDE), or a rotating cylinder electrode (RCE).

Detailed information

• 

  The Pine AFMSRCE rotating ring disk electrode body is a long-selling product. The AFMSRCE is a rotating ring disk electrode that can operate in combination with a potentiostat/galvanostat. By selecting a shaft, you can choose either a rotating disk electrode (RDE), a rotating ring disk electrode (RRDE), or a rotating cylinder electrode (RCE). There are also plenty of accessories available, such as cells for alkaline solutions and gas purge bearing assemblies. Features: - Rotational speed: 100 to 10,000 RPM - External voltage rotation control/rotational speed analog output - Wide variety of electrode types - Silver-carbon brushes for reliable electrode connections - High-quality research grade - Compatible with custom disk mounting

  The WaveVortex10 rotating ring disk electrode is a compact and low-cost type of rotating ring disk electrode designed for laboratory use. It can accommodate both rotating disk electrodes (RDE) and rotating ring disk electrodes (RRDE). Additionally, it integrates the rotor and controller, achieving high performance in a space-saving size. The shaft, similar to the AFE6M, is fixed. E5 series chips (RDE) and E6, E7, and E8 series chips (RRDE) are applicable. Accessories are compatible with AFMSRCE and many others. Features: - Shaft-integrated rotor - Compatible with RDE/RRDE - Low cost - Space-saving (Depth 280mm x Width 380mm x Height 380mm) - Custom inserts can also be used - External input compatible with potentiostat linkage

  E2 Series Rotating Disk Electrode Chips (Compatible Models: AFMSRCE Rotating Ring Disk Electrode) E2 Series RDE Chips (E2 Series FastSpeed RDEs) The E2 Series features an integrated chip and shaft design, making it ideal for high-speed rotation. The maximum rotational speed is 7,000 RPM. Code Product Name AFE2M050AU Gold Disk Chip, Diameter 5mm AFE2M050PT Platinum Disk Chip, Diameter 5mm AFE2M050GC Glassy Carbon Disk Chip, Diameter 5mm

  E3 series RDE chips with interchangeable chips and shafts (maximum rotation speed: 2500 RPM) The combination of the E3 series consists of E3 series chips and AFE3M shafts. The chip body material is Teflon (PTFE), and there are also RDE chips made from PEEK chip body material, which has the industry's highest level of operating temperature ranging from 20 to 80°C.

  The E4 series is an RDE chip that allows for the exchange and installation of inserts from Pine and custom-made ones. The standard size of the insert is a disk with a diameter of 5.0 mm and a length of 4.0 mm. If the material you are researching is shaped into a disk with a diameter of 5.0 mm and a length of 4.0 mm, it can be mounted onto the RDE insert chip (AFE4TQ050) using the disk insert exchange tool (AFE4K050), just like Pine's standard size inserts (see PDF for reference). Pine offers a wide range of materials for polished disks of diameter 5.0 mm and length 4.0 mm (standard size), including platinum, gold, palladium, silver, glassy carbon, and basal-plane pyrolytic graphite. The combination of the E4 series includes disk inserts, insert chips, and the AFE3M shaft. The AFE3M shaft is specifically designed for the AFMSRCE rotating ring disk electrode.

  The AFE5TQ050 and AFE5TQ050PK are RDE chips that can interchangeably use inserts from Pine Corporation and custom-made inserts. The standard size of the insert is a disk with a diameter of 5.0 mm and a length of 4.0 mm. If the material you are researching is shaped into a disk with a diameter of 5.0 mm and a length of 4.0 mm, you can use the E5 and E6 disk insert exchange tool (AFE6K050) to first attach it to the U-CUP and then set it onto the AFE5TQ050 or AFE5TQ050PK chip. Compared to the E4 series, using the U-CUP makes it easier to install and secure the disk insert. If you are using the AFMSRCE rotating ring disk electrode body, you will use the AFE6MB shaft. If you are using the WaveVortex10 rotating ring disk electrode body, it will connect directly to the fixed shaft.

  E6 Series ChangeDisk RRDE Tips It is possible to repeatedly attach and detach the preferred disk material to the Pt, Au, or GC ring assembly for RRDE measurements. The E6 series is similar to the E4 series, featuring RRDE tips with interchangeable disk materials. Customers can prepare their research materials in the form of a disk insert with a diameter of 5.0 mm and a length of 1.5 to 4.0 mm, which can be easily set into the RRDE chip holder using the RDE disk material exchange tool (AFE6K050). The ring selection for the RRDE chip holder includes platinum, gold, and glassy carbon. The disks are the same as those in the E4 series, with PINE polished inserts of diameter 5.0 mm and length 4.0 mm (INSERT; platinum, gold, and carbon can be used). The combinations for the E6 series include electrode inserts, RRE chip holders, and AFE6MB shafts. Applications include research on fuel cells, corrosion studies, etc.

  E8 Series - Industry's Highest Capture Rate Rotating Ring Disk Electrode Chip The E8 Series is a new product from PINE Corporation. Its feature is a high capture rate. The thickness of the ring increases the capture rate. It achieves the highest theoretical capture rate (43.9%) among commercially available RRDE chips. The separator (insulating ring) fixed between the disk and the ring is made of Teflon (PTFE), which is more hydrophobic than PEEK, preventing water droplets from spreading from the disk, as shown in the diagram on the right. Membrane modification on the disk is beneficial. Disk outer diameter (R1) = 5.00 mm Ring ID (R2) = 6.00 mm Ring outer diameter (R3) = 8.50 mm Highest theoretical recovery efficiency = 43.9% The disk and ring are fixed, with a PTFE Teflon separator and an outer diameter of 15.0 mm PEEK shroud.

  The quartz glass cuvette-type spectroelectrochemical cell features a honeycomb electrode chip that includes on-board working electrode, counter electrode, and reference electrode screen-printed on a ceramic substrate (using conductive platinum or gold ink). The working electrode has holes in a honeycomb pattern that allow light to pass through the electrode. The active surface of the working electrode includes a metal coating along the inner walls of the holes. As light passes through the holes, the beam grazes the walls of each hole. Typically, the path length of electrochemically generated species is within the diffusion layer near the surface of the electrode. In our honeycomb design, the effective path length is the length of the honeycomb card (1.7 mm). As a result, molecules with low absorbance coefficients can be detected more easily.
