Millikan Oil Drop Apparatus

 

Very Small Error Rate

The Millikan Oil Drop Apparatus has an average relative error of less than 2%, which is excellent for student laboratories. The parallel plate spacing is 5.00 mm, with an accuracy of ±0.01 mm. The plate voltage ranges from 0 to 680 V DC, with selectable positive, zero, and negative settings, and switchable polarity. The balance voltage ranges from 0 to 350 V DC. The lifting voltage is automatic and is set to 140% to 160% of the balance voltage. The buttons are designed to withstand more than one million operations.

This apparatus displays voltage on a digital screen, with a range of 0 to 999 V and an accuracy of 1 V. The timer ranges from 0 to 99.99 seconds, with an accuracy of 0.01 seconds. The built-in measuring scale has a total range of 2 mm and supports two selectable divisions: 0.25 mm and 0.04 mm per division. The microscope provides 60× magnification. The CCD sensor offers high sensitivity at 0.01 lx, with a resolution of 600 TV lines. Students can perform experiments using either the dynamic or static method. The apparatus also includes data processing software.

The apparatus can keep oil drops stable for more than one hour and can track a charged droplet for over two hours. LED illumination ensures that the droplets appear bright and clear. A 15-inch color monitor displays the observation results.
