Neuroscience Research Equipment

DC Temperature Control System

The DC Temperature Control System is designed to maintain a constant temperature of a subject. There are two options to perform this:
using a Heating Pad with a Mini Rectal Thermistor Probe
or
using a bath with the Liquid Immersion Heating Rod and a Liquid Thermistor Insert, without introduction of electrical interference.
The proportional DC power supply slowly varies its output to the heating element based on the resistance of the monitoring thermistor. Electrical noise and switching transients—common in AC-based devices—are eliminated. Heating Pads come in 12.5x25cm, 25x25cm, 10x12.5cm, 6.5x9.5cm, and 5x12.5cm.

Oscillating Tissue Slicer

The OTS5000 Tissue Slicer sections fresh tissue slices in user-defined travel windows and reduces blade travel time between sections. Slicer head design minimizes vibration that causes tissue distortion. (<20 micron Z movement).
