A385R WITH AN A382 BATTERY CHARGER, HIGH CURRENT ISOLATOR |
|---|
High Current Stimulus Isolator
The A385 is an optically isolated current source, which can generate up to 100 mA of unipolar or biphasic constant current pulses or DC. Pulse duration is controlled manually or by an external 5V command. Output current amplitude is determined by a 3-digit 10-turn potentiometer. Maximum output voltage between the stimulating electrodes is +36V.

Micro Nitric Oxide Sensors
The ISO-NOP007 has a tip diameter of just 7 microns and a length of 2mm. The response is linear over a wide dynamic concentration range of NO. The design is based on a single carbon fiber coated with WPI's NO-selective membrane. A detection limit of approximately 1 nM NO makes this electrode ideal for use in tissues and microvessels.
Von Frey Probe
To assess mechanical allodynia, which is a painful response to a light touch or pressure from a stimulus that is not normally painful, the Electronic von Frey Anesthesiometer was developed. The Electronic von Frey meter uses one of 15 different flexible von Frey hairs called “SuperTips™” (or rigid tips up to 800 grams). Each hair, regardless of model chosen, is exactly 0.8 mm in diameter. This uniformity of design eliminates false readings and allows for comparison of test results. The Electronic von Frey can be used with chart recorders and analog/digital converters, and it never needs calibrated. This system includes either a 90, 800 or 1,000 gram probe. Mesh stands are available in a variety of sizes for large group studies.

Dummy Load Resistor Kit
A365 can be used as a precise voltage source by placing a precision “dummy” resistor load across the output terminals. Precision resistors (such as the 100 Ω, 1000 Ω and 10,000 Ω resistors in WPI’s optional Dummy Load Resistor Kit #DRL) when placed across the output terminals convert the precision current levels to accurate voltage levels.
For example, 1 milliampere flowing through 1000 Ohms will produce 1 volt across the output terminal pair. Thus, models A365D and A365R can be used as low noise sources of accurate voltage pulses or DC. To maintain less than 1% error, avoid shunting the output dummy resistor with a load resistance less than 100 times the dummy resistance value.

Classic Small Animal Anesthesia System
Complete small animal anesthesia system and all the accessories
EZ Anesthesia is the system of choice for anesthetizing small animals, and it comes with a variety of choices. Animals to be anesthetized are placed in the acrylic induction chamber, and the system delivers a precisely blended mixture of oxygen and isoflurane. An activated charcoal air filter canister at the top of the chamber releases safe, filtered air back into the room. A water-heated cage warmer or warming plate (ATC2000) is used to retain the animal body temperature while in the induction chamber. After the initial anesthetizing, the animal may be moved to the heated surgical water bed and positioned properly in the snugly fitted nose cone. A highly sensitive valve regulated by the animal’s breathing works with the nose cone to ensure non-rebreathing efficiency. It allows safe anesthesia for up to several hours. The breathing device also includes an air filter that releases safe, filtered air back into the room.
