The ATC 2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. Here are five reasons to choose the WPI Animal Temperature Controller. WPI's Adaptive control is unique in the industry, giving you precision control without the need for complex programming when it counts. Simple to setup. Stable control. No local hotspots.
1. ELECTRICALLY QUIET:
The DC heater is extremely quiet in terms of electromagnetic radiation. This is essential in electrophysiological recordings which are very sensitive to electromagnetic interference.
2. PRECISE & STABLE CONTROL:The controller uses proportional, integral, and differential (PID) technology in adjusting the DC voltage output. Compared with switched on/off type controllers, PID controllers provide a much more precise and stable control of temperature. The PID approach is also more immune to the variation of the experimental conditions such as change in animal size and unexpected disturbances.
3. OPTIONS FOR CONTROL:The controller has three temperature sensing inputs that give you options for control.
- The resistive temperature device (RTD) probe input can be used to monitor an RTD rectal probe to control the animal temperature or to monitor ambient temperature, induction chamber temperature or any other temperature.
- When using a thermocouple probe, the thermocouple (TC) probe input can be used just like the RTD input. (TITLE: A T type thermocouple must be used.)
- The heater plate also has an internal temperature sensor. The ATC2000 monitors this sensor to prevent the localized hot spots under animal.
4. ADAPTS TO DIFFERENT SIZE ANIMALS AUTOMATICALLY:Adaptive mode, one of three operational modes, uses the temperature of the heated plate and the temperature of the subject to automatically adjust the PID parameters, regardless of the animal’s size. This approach is less prone to overshoot, but somewhat slower than normal mode to stabilize, depending on the sampling rate used.
5. ELIMINATES LOCAL HOTSPOTS:The plate’s internal temperature sensor prevents localized hot spots under the animal with maximum temperature stability. The Shutdown mode is a fail-safe mode used if the plate temperature ever exceeds your shutdown set point. (TITLE: By default, the shutdown set point is 37ºC.)

Adjustable Height/Working Distance
WPI's 3D SpectaSCOPE™ Inspection Scope is a true 3D digital stereo optical scope with a host of innovative patent-pending features.
It all starts with the fully optical zoom system, which is sending the smallest details to its two powerful HD 5MP cameras. The images are then transmitted at full speed frame rates to the on-board HD screens, giving you a true three-dimensional image. You choose the most comfortable position for the viewer’s tilting headset.
The 3D SpectaSCOPE™ is easy to set up. Here we show you how to adjust the height and working distance of the 3D SpectaSCOPE™.

Ultrasonic cleaning is the most effective cleaning method for maintaining your surgical instruments, because of its cavitation. Vibrating sound waves create micron-size bubbles in solution that grow as the pressure in the unit changes. Eventually the bubbles implode. The bursting bubbles effectively dislodge debris, even in the most difficult to reach places. Use of ultrasonic detergent greatly improves the effectiveness of the cleaner, because it increases the number of tiny bubbles
- Immediately after use, rinse instruments under warm or cool running water to...more

After a good cleaning and disinfection, your surgical instruments may be sterilized using a variety of methods. The chart below shows two common methods, autoclaving and cold sterilization. Sterilization destroys all microbial life. Some chemical sterilants can be used as high level disinfectants (HLD) when used for shorter exposure periods.
- You can sterilize your instruments by soaking them in a chemical sterilant like Cidex Plus® for 10 hours at 25°C. This process may be detrimental to fine instruments.
- Dry heat or autoclaving are the preferred methods of sterilizing surgical instruments. Typically, surgical instruments are sterilized by autoclaving. Autoclaving, which is saturated steam under high pressure, is the most common method for sterilizing surgical instruments. If you prefer to autoclave, instruments may be autoclaved individually or in sets. ...more
