Open Case Form Electroscope
Product Specification Sheet
Open Case Form Electroscope
Model Number: MTEE-18
The Open Case Form Electroscope is designed for detecting and investigating electrostatic charge through the deflection of a freely rotating aluminized plastic straw. The pointer rotates on the saddle of a conducting rod, while a graduated rear scale allows the deflection angle to be measured. The conducting rod is recessed within the metal housing to help shield the mechanism against unwanted air currents.
Product Specification
The Open Case Form Electroscope is a sensitive electrostatic apparatus designed to provide a clear visual indication of electric charge through angular deflection.
Instead of conventional delicate metal leaves, the instrument uses an aluminized plastic straw as its indicating element. The lightweight straw is mounted so that it can rotate freely on the saddle of the conducting rod.
When electrostatic charge is introduced to the conducting system, the resulting electrostatic interaction causes the lightweight indicator to deflect. This provides an easily observable response to the presence and behaviour of charge.
A graduated scale positioned at the rear of the instrument is marked in degrees, allowing the angular deflection of the indicator to be measured rather than simply observed.
The conducting rod is recessed within the metal housing, helping protect the sensitive indicating arrangement from unwanted movement caused by air currents. This improves the stability of observations during electrostatic experiments.
The instrument is supplied with replacement aluminized straws, providing convenient replacements for continued experimental use.
The Open Case Form Electroscope can be used with suitable friction rods, electrostatic charge kits, and other compatible charge sources for experiments involving charge detection, electrostatic induction, charge transfer, and comparative charge investigations.

FAQs
What is an Open Case Form Electroscope used for?
It is used to detect electrostatic charge and observe or measure the resulting deflection of a lightweight indicator.
What is used as the indicator?
The instrument uses an aluminized plastic straw as its lightweight electrostatic indicator.
How does the indicator move?
The aluminized straw rotates freely on the saddle of the conducting rod.
Does the instrument have a graduated scale?
Yes. A scale positioned at the rear is graduated in degrees for measuring pointer deflection.
Why is the conducting rod recessed?
The conducting rod is recessed within the metal housing to help shield the sensitive indicator from unwanted air currents.
Can the amount of deflection be measured?
Yes. The graduated scale allows the angular deflection to be read in degrees.
Are replacement indicators supplied?
Yes. Replacement aluminized straws are supplied with the apparatus.
Can it be used for electrostatic induction experiments?
Yes. It can be incorporated into suitable experiments involving electrostatic induction and charge transfer.
Can it be used with friction rods?
Yes. Compatible friction-charging rods can be used as electrostatic charge sources.
Does it require an external power supply?
No. The electroscope itself does not require an external electrical power supply for basic electrostatic charge experiments.
Can Open Case Form Electroscopes be supplied in bulk?
Yes. Micro Technologies can supply Open Case Form Electroscopes for bulk orders, distributor requirements and institutional laboratory procurement.
