The 7000smz-2 unit with a Z-axis deflection of Sub-Micron has a blade advance controllable to 10 microns/second. The 5100mz-Plus and 5100mz are very competitively priced high precision units with a Z-axis deflection of only 1-2 microns and a blade advance controllable to 10 microns/sec. On all units the section thickness step size is 0.001 mm. The 7000smz-2 and 5100mz-Plus are supplied with their own Z-axis calibration verifier.
All types of sectioning are 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 7000smz-2 will now deliver perfect sections every time with sub-micron Z-axis deflection across a wide range of vibration speeds and amplitudes. The affordable 5100mz-Plus 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-2 and both 5100mz models 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 7000smz-2 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.
The new 5100mz series Vibrating Microtomes share the user interface with the premium 7000smz-2, placing a wide range of adjustable parameters at the user's fingertips. Use in fully manual or the semi-automated "slice window" mode which automatically remembers the start and finish position of the slice.

1. Temperature Controlled Standard Tissue Bath
Product Description
The 7610-A Tissue Bath Cooler Unit is intended for use with our 7000 and 5100 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.

2. Integrally Mounted Cold Light Source
Model 7000-2-1
Product Description
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.
Product Features
- 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 500 mm fiber optic light guides
3. Integrally Mounted Magnifying Glass
Model 7000-1-3
Product Description
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 80 mm is ideal for the task.
Product Features
- 115 mm Diameter
- 305 mm Focal Length
- 2x Magnification

1. Ceramic Blades
Model 7550-1-C
Product Description
The new blade holder design is now included with all Integraslice and Vibroslice instruments. 7550-1-C and 7550-1-SS are designed for new Integraslice instruments.
Product Features
- Made from ultra hard zirconium
- Honed by a process of "lapping" both sides of the single bevel to micron flatness
- Great rigidity, hence a straight cutting edge
- Prolonged slice life, especially in the most difficult of tissues such as young brain or very old brain
- Inert and impervious to corrosion
- Initial higher cost is offset by its longevity
- Fits into a special blade holder now standard on both Integraslice and Vibroslice instruments
2. Stainless Steel Blades
Model 7550-1-SS
Product Features
- Double beveled on both faces, honed to an acute cutting edge and hardened to 56 Rockwell.
- Nevertheless, stainless steel is relatively soft and these blades are usually used once or at a maximum changed every day.
- These blades are for use in specially designed blade holders for Vibroslice instruments manufactured prior to 2003.
