應用

腐蝕

催化劑開發

燃料電池研究

控制反應物向電極表面的物質傳輸

旋轉圓環-圓盤電極（RRDE）用於在圓盤電極處監測生成物。 此類實驗需要配備雙恆電位儀。 Gamry提供一台專用儀器，使用兩台Gamry標準恒電位儀連接至同一電腦，實現數據同步收集。 此外，還提供多種RRDE配置，包括鉑-鉑電極、金-金電極以及玻碳-玻碳電極，滿足多樣化的實驗需求。

旋轉盤實驗的實驗條件：確定樣品電極的反應物與生成物品質傳輸，催化劑評估等。

旋轉圓柱實驗對於石油產業至關重要，它可以類比管道內的腐蝕環境，從而省去了流量迴路裝置的高昂開支。 旋轉器是一種理想的工具，即使在低轉速下，轉輪處通常也能維持紊流的流動狀態。 圓筒可採用多種不同金屬製成材料，包括1018碳鋼、316不鏽鋼和430不鏽鋼，以評估其腐蝕性能。 同時，還支援使用者根據實際材料定製加工圓筒樣品。

旋轉器的電極需單獨購買，覆蓋廣泛的標準物質材料，如金、鉑、玻碳、碳鋼、不鏽鋼等。 此外，我們還提供材料定製服務。

The RxE 10kTM Rotating Electrode (Part #992-00146) is a research-grade rotator and features the ability to use rotating ring-disk and cylinder electrodes. It can be used as the working electrode in any electrochemical cell with any Gamry potentiostat.

The RxE is digital (USB) or analog controlled. Rotation rates are 50-10500 rpm. Our one-piece shaft design actually allows us to rotate at those speeds. The RxE accuracy over this rotation rate range is +/- 1rpm.

Overview

The RxE 10k Rotating Electrode is a research-grade rotator and features the ability to use rotating ring-disk, disk and, cylinder electrodes. The rotation rate is adjustable from 50 – 10500 rpm (revolutions per minute). The Controller has a Liquid Crystal Display (LCD) which indicates the rotation rate and is controlled by a rotation rate knob. Alternatively, the rotation rate may be controlled by your Gamry Interface or Reference family instrument. The electrode assembly of the rotator has a versatile design that allows for the use of diverse electrode types. Different shaft and electrode tips can be selected depending on your desired use. Different shafts are used for disk and cylinder or ring–disk experiments.

Applications

• Corrosion
• Catalyst Development
• Fuel Cell Research
• Controlling Mass Transport of Reactants to Electrode Surface

Rotating ring-disk electrodes are used where products generated at the disk electrode are monitored at the ring electrode. A bipotentiostat is required for these experiments and Gamry can supply an instrument using two standard Gamry Potentiostats collecting data synchronously when connected to the same computer. A number of ring-disk electrodes are available including platinum-platinum, gold-gold and glassy carbon-glassy carbon.

Rotating disk experiments are performed where defined mass transport to the sample electrode is desired. An example of this type of experiment would be catalyst evaluation.

Rotating cylinder experiments are important in the oil industry to simulate the corrosion environment inside a pipeline, thus avoiding the need to assemble expensive flow loop setups. The rotator is an ideal tool because flow conditions at the rotating cylinder are generally turbulent even at low rotation rates. Cylinders can be made from a variety of different metals to evaluate their performance including 1018 carbon steel, 316 stainless steel and 430 stainless steel. Users can machine cylinder samples using their actual material.

The electrodes for the rotator are sold separately and include a wide selection of standard materials such as gold, platinum, glassy carbon, carbon steel, stainless steel, etc. Custom materials are available on request.
