The Actophoto Meter is an essential instrument used in pharmacological research to measure the locomotor activity of small animals like mice and rats. This advanced digital Actophoto Meter operates on the principle of photoelectric cells, which detect the movement of the animal within a confined area. By recording the number of times a light beam is interrupted, the Actophoto Meter provides an accurate, objective measurement of CNS activity, drug effects, and behavioral patterns.

Engineered for precision, the Actophoto Meter is widely utilized by pharmaceutical scientists to study the stimulant or depressant effects of various drugs. Unlike manual observation, using an Actophoto Meter ensures that the data collected is free from human error. It is often used in conjunction with other specialized tools such as the ESAW Analgesiometer or the Eddy's Hot Plate to provide a comprehensive profile of a drug's pharmacological impact.

Primary Uses in Pharmacology

The Actophoto Meter is primarily used for screening psychotropic drugs. It effectively measures changes in spontaneous motor activity caused by stimulants, tranquilizers, and sedatives. Researchers rely on the Actophoto Meter for toxicity testing and evaluating the onset of action of experimental compounds in pre-clinical trials. It is a cornerstone device for any modern animal behavior laboratory.

Frequently Asked Questions (FAQ)

Q1: How does the Actophoto Meter record animal movement?
The device uses a series of infrared (IR) light beams. When the animal moves and breaks a beam, the internal digital counter records one "actophoto" count automatically.

Q2: Can the Actophoto Meter be used for both mice and rats?
Yes, the chamber is designed to accommodate standard lab-sized mice and rats comfortably for locomotor activity studies.

Q3: Is the digital counter resettable?
Absolutely. The Actophoto Meter features a quick-reset button to clear previous readings before starting a new experiment session.

Q4: Why is a photoelectric Actophoto Meter better than manual scoring?
It eliminates subjective bias and provides continuous, 24-hour monitoring without tiring, ensuring the highest level of data integrity in pharmacology.
