Small Animal Testing Chamber Technilabs markets an environment controlled chamber for small animal testing with built-in sensor lines. The sensor lines allow testing up to 24 animals in heated chambers. The construction of the walls and doors eliminates ambient noise. Sound isolation between blower and chamber is said to prevent intrusion of vibration from blower motors to chamber. A new universal scanner converts existing indirect blood pressure channel to 6 automated channels. No wiring is needed to use the above noted chambers as a blood pressure monitoring system.
