ELECTROCHEMICAL TEST FIXTURE

Button Cell Fixture

Designed for connecting and testing button-shaped samples, button cells, and small conductive components. Available with 10 cm, 20 cm, and 30 cm cable lengths.

Button Sample ClampingQuick ConnectionMultiple Cable LengthsLaboratory Testing

Product Overview

The button cell fixture is a laboratory connection fixture for small circular samples and button-shaped test objects. Its integrated clamping structure and cable establish an electrical connection between the sample and test equipment.

Choose a 10 cm, 20 cm, or 30 cm cable according to the laboratory bench layout, instrument position, and sample installation space. The shorter cable is suitable for close connections, while the longer options provide more flexible routing.

Before purchase: Confirm the sample size, fixture installation method, and required cable length to avoid insufficient connection distance or an incompatible sample size.

Product Features

For Small Samples

Suitable for button-shaped, disk-shaped, and other small conductive samples.

Three Cable Lengths

Available in 10 cm, 20 cm, and 30 cm lengths for different connection distances.

Convenient Connection

The fixture and cable form an integrated connection structure for easy installation, removal, and repeated testing.

Applications

Button Cell Testing

For laboratory connections and basic performance testing of button cells and similar circular devices.

Electrochemical Experiments

For connecting small electrode materials, conductive disks, and laboratory components.

Teaching and Research

Suitable for university teaching, materials screening, and research testing platforms.

How to Use

  1. Turn off the test equipment output and confirm that the fixture and cable are in good condition.
  2. Clean the sample contact area so that oil or insulating residue does not affect electrical contact.
  3. Place the button-shaped sample in the corresponding fixture position and secure it firmly.
  4. Check the sample polarity and confirm that there is no accidental short circuit between test terminals.
  5. Connect the cable to the test equipment and set the parameters according to the experiment.
  6. Turn off the output before removing the cable and tested sample after the experiment.

Maintenance and Precautions

  • Use the fixture only with samples that meet the required dimensions and clamping conditions. Do not force installation.
  • Confirm sample polarity and the instrument wiring configuration before testing.
  • Prevent the two test terminals from touching directly to avoid short circuits.
  • Keep the sample contact surfaces clean, dry, and stable during installation.
  • Hold the connector when removing the fixture. Do not pull the cable itself.
  • Keep the fixture and cable away from corrosive solutions and hot surfaces.
  • Stop using the product if the cable, insulation, or electrical contact is damaged or loose.
  • Clean the product and store it in a dry, light-protected environment when not in use for an extended period.

Frequently Asked Questions

How should I choose between 10 cm, 20 cm, and 30 cm?

Select the length according to the distance between the fixture and test equipment. Choose 10 cm for close connections, 20 cm for routine use, and 30 cm when more routing space is needed.

Can it be used with different sizes of button-shaped samples?

Confirm the actual clamping range of the fixture. Check the sample diameter, thickness, and contact position before purchase.

How should unstable test data be investigated?

Check whether the sample contact surface is clean, the fixture is secure, and the cable and instrument interfaces are firmly connected.

Can the fixture remain in contact with electrolyte for a long time?

Long-term contact between non-immersed fixture components and electrolyte is not recommended. Clean and dry the product promptly after the experiment.
