The EMS 4500 Oscillating Tissue Slicers represent the most thoughtfully designed solution to sectioning either fixed or fresh tissue, as thin as 5 microns. No longer is there a need for embedding or freezing your sample, and preparation time is reduced dramatically. The risk of distortion and artefacts normally associated with these procedures is eliminated. The EMS 4500 and 5000 meet the highest standards for precision and accuracy as well meeting or exceeding the performance of units on the market costing twice as much.

Applications

The EMS 5000 series may be used for the sectioning of samples in the fields of electrophysiology of fresh tissue, immunocytochemistry and immunohistochemistry, neurophysiology, neuropathology, experimental biology, histology, cytology, botanical research, microscopy, polymer and materials science. The EMS 5000 now features a new design of the slicer head which minimises Z-axis vibration. This improvement dramatically improves slice surface integrity and is especially beneficial in the field of fresh tissue where IR/DIC imaging methods are concerned. The unique blade holder has now been modified to accept razor, sapphire, diamond and glass blades.

Programmable travel window

To reduce time between slices the EMS 5000 series features a user programmable travel window (cutting window). This allows the sectioning cutting range of the blade to be customised to the specimen sample. This feature of "automatic sectioning" offers a beginning advance and end advance, further automating the EMS 5000. In conjunction with the "home button" the programmable window guarantees rapid sectioning of even the largest of specimens. As well, the EMS 5000 allows the sectioning of samples in two different modes. In single slice mode, the unit sections samples and harvests them while the blade repositions itself to perform the next slice, and in the multiple slice mode the EMS 5000 will automatically perform multiple uniform slices.

Control panel

The EMS 5000 series control panel has been totally redesigned to allow for ambidextrous and ergonomic operation. The keypad has been sealed to avoid buffer spill seepage. The tray is made from moulded clear polycarbonate for improved viewing of the slicing operation. The tray is removable to facilitate specimen mounting and cleaning. Two white LEDs are installed in the blade head, which provide constant cold illumination of the specimen during the slicing process.

Slicing

The EMS 5000 series is engineered for maximum stability, which ensures even the most delicate of tissue to be cut successfully every time. The knife holder allows any blade (as per list) to be secured and the blade angle set from 10- 20 degrees. The specimen mount is x, y, z axis adjustable and the knife advance is continuously adjustable with a touch of the keypad from 0- 5mm/s and the section thickness is now adjustable in 1 micron increments ranging from 1-999 microns. The precision slicer features automatic touch selection of section thickness, blade speed, advance and a user-defined travel window, so that the consecutive sections may be cut easily and rapidly. Other EMS 5000 features include touch pad control of the blade height, slice counter / slice thickness, precise bar graph displays of blade oscillation and advance speeds. Blade oscillation is adjustable from 50-5000 cycles/minute and advance speed is adjustable continuously from 100 microns - 5mm/sec.

Mounting of specimens

The tissue pedestal with pivotal pin (included with media tray), allows for the mounting of a specimen directly to the pedestal and the ability to change the angle of your specimen relative to the blade, offering you perfect specimen orientation. The sample vice with pivotal pins (also included in package) allows for the adherence of your specimen directly to a mounting block.

Maintenance

Our EMS 5000 series is designed for easy operation and maintenance. The specimen collecting tray is removable and easy to clean. All controls may be set with one hand with options for multiple slicing modes.

Accessories

The unit comes complete with gooseneck magnifying lens, media tray (63mm wide) and pedestal, specimen vice holder, blocks, as well as a foot switch with 1.8m cable. A large tray (89mm wide) is available as an option and comes complete with fixed stage and adjustable pedestals.

EMS 4500 Tissue Slicer

The EMS 4500 is a scaled down version of the EMS 5000. It has the same specifications as the EMS 5000. The difference between the two units is that the EMS 4500 does not include the following features and accessories:

• Adjustable window
• Multi-slice function
• Home functionality
• Foot switch
• Tissue blocks
• Vice holder

The EMS 4500 can be upgraded to the complete EMS 5000 unit at any time.
