AmazonProduct Overview
The JJ110 PTFE platinum sheet electrode holder is an electrochemical fixture for securing laboratory samples and providing electrical connection. Tightening the screw clamps the sample between the upper and lower jaws and connects it to the external test equipment.
It is suitable for platinum sheets, carbon cloth, conductive glass, and other conductive samples used with electrochemical workstations, cyclic voltammetry, potentiostatic testing, corrosion testing, and materials research.
The series includes standard, reinforced, all-platinum-conductive, strong-acid-resistant, L-shaped platinum sheet, PEEK, graphite, and PTFE accessory configurations.

Standard and Reinforced Structures
Standard Type
Uses 0.6 mm platinum wire welding and a single silver-wire conductor inside the electrode rod. Suitable for routine low-current experiments.
Reinforced Type
Uses 0.8 mm platinum wire welding with a larger weld contact area and four silver-wire conductors for improved strength and current capacity.
Strong-Acid-Resistant Type
Designed for environments with higher corrosion-resistance requirements. Confirm media compatibility with the actual solution before use.
PEEK Type
PEEK provides high hardness, strength, and temperature resistance. Select carefully for strongly acidic environments.
How to Use
- Place the sample to be tested between the two jaws.
- Adjust the sample position so the clamping area is flat and the pressure is even.
- Tighten the fixing screw to secure the sample between the jaws.
- Connect the electrode rod to the electrochemical workstation or test instrument.
- During testing, immerse only the sample in the electrolyte whenever possible. Avoid long-term immersion of the holder head and weld points.
Precautions
- Do not immerse the holder head in the electrolyte for extended periods.
- The weld points are sealed with adhesive. Long-term immersion may cause contamination, corrosion, or liquid ingress.
- Use at normal temperature and pressure, preferably between 10 and 40 degrees C.
- Do not use with aqua regia or 36% concentrated hydrochloric acid.
- Do not clamp lithium sheets or expose the holder to solutions that react with platinum.
- Avoid prolonged ultrasonic cleaning whenever possible.
- Recommended working current is below 1 A. Choose the reinforced type for higher currents.
Frequently Asked Questions
How should I choose between the standard and reinforced types?
Choose the standard type for routine low-current testing. The reinforced type is recommended for higher current, longer testing periods, or applications requiring stronger weld points.
Can the electrode holder be immersed for a long time?
Long-term immersion is not recommended. Keep the holder head and weld points above the liquid level whenever possible and immerse only the test sample.
Can it hold carbon cloth and conductive glass?
Platinum sheet holders and some PEEK holders can hold carbon cloth, conductive glass, and similar samples. Stainless-steel and copper holders are not recommended for soft or fragile materials.
What is the maximum sample thickness?
Normal clamping thickness is no more than 2 mm. Confirm the actual limit according to the jaw opening and sample hardness.
