EMS7000smz and EMS5000mz
Our top-of-the-range high precision, vibrating microtomes, are the finest slicers in the world for all specimen preparation.
The EMS5000mz is a very competitively priced high precision unit with a z-axis deflection of only 1-2 microns and a blade advance controllable to 10 microns/sec. The EMS7000smz unit has a Sub-Micron z-axis deflection and a blade advance controllable to 10 microns/second. On both units the section thickness step size is 0.001mm and each vibrating microtome is supplied with its own z-axis calibration verifier. All types of sectioning is possible including sectioning for visual patching of neurological tissue, heart, and lung, and much more.
The effect of excessive Z-axis deflection on the health and viability of the tissue preparation has been much discussed since the publication of Jonas et al (2003) and the EMS7000smz will now deliver perfect sections every time with sub-micron Z axis deflection across a wide range of vibration speeds and amplitudes.The affordable 5000mz offers almost the same features with Z-axis deflection of 1-2 microns at all vibration speeds and amplitudes, which is less than most other microtomes on the market.
The all-new user interface is both easy to use and versatile. The 7000smz and the 5000mz offer similar operation at the press of a button. The versatility includes simple operation at the push of a button or a range of changeable and programmable parameters and a menu enables the settings of your own preferences.
The EMS7000smz also gives you longevity of performance, in other words it not only gives submicron performance out-of-the-box but the advance vibrating mechanism does not contain bearings and other components subject to wear. Consequently it will retain the sub-micron Z-axis deflection performance for years to come, giving you consistency in your biological preparation.
Tissue cooling is accomplished by the use of either an ice-water bath or an electronically controlled thermo-electric cooler. Other options include a LED cold light source and a magnifier or a stereoscope for clear observation whilst slicing.

- Temperature Controlled Standard Tissue Bath
The EMS 7610 Tissue Bath Cooler Unit is intended for use with our EMS 7000 and EMS 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 EMS 7610 Series coolers use "Peltier" thermoelectric elements. The stainless steel tissue bath and mount are detachable to allow sterilisation 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.

(*Note that the actual temperatures achievable will be dependent upon the solutions used and local temperature conditions)
2. Integrally Mounted Cold Light Source
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.
- Ability to direct the light where needed with two flexible fiber optic light guides.
- Maintains temperature stability of the tissue or surrounding a.c.s.f.
- Light Intensity is adjustable by a rotary dial knob.
- 20W/12V Halogen lamp
- 2000 hour life approx.
- Fan and electronic power supply
- Adjustable with potentiometer
- Twin 500mm fibre optic light guides
3. Integrally Mounted Magnifying Glass
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.
- 115mm Diameter
- 305mm Focal Length
- 2x Magnification
