Temperature Controlled Standard Tissue Bath Model 7610


The 7610-A Tissue Bath Cooler Unit is intended for use with our 7000 and 5000 range of vibrating microtomes. Unfixed brain slices sectioned at 4°C give better tissue preservation and are viable for longer in-vitro recordings. Additionally, some enzyme histochemical techniques give better staining results when sectioned at low temperatures.


The 7610 Series coolers use “Peltier” thermoelectric elements. The stainless steel tissue bath and mount are detachable to allow sterilization by autoclave if required.


The equipment comprises of a mains operated control unit, cooling


element, tissue bath and specimen holder. The control unit houses a power supply and temperature control circuitry. The cooling element assembly consists of thermoelectric “Peltier” elements, temperature feedback sensors and a cold water fed heat exchanger.


Current from the power supply flows through the thermoelectric elements, which act as heat transfer units. Heat is drawn off, cooling the solution in the tissue bath. The heat generated by this process is removed by the water supply fed through the heat exchanger. The unit uses a proportional temperature control algorithm to maintain temperature stability. This will hold the bath temperature to within 0.5°C of the temperature set point. There will, however, be a small variation in temperature vertically through the bath. Experience will show the best temperature to be set for any given requirement and ambient temperature.

Integrally Mounted Cold Light Source Model 7000-2-1


To facilitate the careful slicing operation, it is most important that the progress of the blade through the tissue be clearly observed. This observation is used to ensure control of the speed of advance and of the oscillation of the blade. Two elements are required for clear observation, light and magnification.


Features


z Ability to direct the light where needed with two flexible fiber optic light guides.


z Maintains temperature stability of the tissue or sur- rounding a.c.s.f.


z Light Intensity is adjustable by a rotary dial knob. z 20W/12V Halogen lamp z 2000 hour life approx. z Fan and electronic power supply z Adjustable with potentiometer z Twin 500mm fiber optic light guides


Integrally Mounted Cold Light Source and Magnifying Glass


Model 5100-1-3


A magnifying glass for general global slices offering approximately 1.5x magnification. Integral cold light powered directly via the Model 5100mz Vibrating Microtome.


Upgrade Kit for 5100mz Model 5100-1-45


Optional kit to upgrade the 5100mz to the 5100mz-Plus. Allowing the user to optimally calibrate the Z-axis deflection of the blade to 2± 0.1 µm.

For general global slices a magnifying glass offering approx 2x magnification is sufficient. However, if specific loci are under study then an inspection microscope is desirable. The binocular inspection microscope with 10x-40x magnification, a zoom of 1x-4x and a working distance of 80mm is ideal for the task.
