The EMS 5000 with or without refridgeration series may be used for the sectioning of samples for use 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 innovative 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.

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 our 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.

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 LED's are installed in the blade head, which provide constant cold illumination of the specimen during the slicing process.

The EMS 5000 series is engineered for maximum stability 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. Our 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.

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.

The unit comes complete including: media tray (2.5in) with pedestal, specimen vice holder for 2.5inch tray, razor blades (25/pk), anodized aluminum blocks- both sizes (3/pk), foot switch with 6in cable, gooseneck magnifying lens LED lights, adhesive,   1 ?16in hex key for blade angle adjustment, and operating instructions, 110V-240V.

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.

The EMS 5000 series meets the highest standards for precision and accuracy. It meets or exceeds the performance of units on the market costing twice as much.

• The specimen tray is made from a clear polycarbonate for improved viewing of the slice operation. No worry of leakage and section visualization in easy.
• The pivot pins which come as a standard on the pedestal as well as the vice holder allow changing of the angle of the pedestal relative to the blade. Easy sample orientation in all directions.
• The tray includes a lock on feature for a more secure mount to the platform.
• The standard unit comes complete with our unique pivotal tissue pedestal (you can mount the specimen directly on the pedestal without the need for vices or blocks mounted in the sample tray).

• The EMS 5000 Refrigerated Controller and Tray

  The EMS 5000 Refrigerated Controller and Tray provide refrigeration capabilities to the 5000 Tissue Slicer. The controller three digit LED displays the current temperature of the bath medium in degrees C. The temperature is maintained within 0.5°C. The temperature range on the unit is between 0-10°C.

  The refrigerated tray is fitted with a peltier heat exchange unit. A cold water source is circulated through the assembly to transfer heat. The tubing is connected to the tray with quick connect fittings. No tools are necessary for installation. The fittings are self sealing to prevent leaking during installation. The tray fits directly to the mounting platform of the EMS 5000. (Image 2)

Blade Position

Forward: Moves the blade arm forward at the set advance speed. Press once to begin movement, again to stop.

Reverse: Moves the blade arm back at the maximum travel speed. Press once to begin movement, again to stop.

Up: Moves the blade arm up. Momentarily pressing the button moves the blade arm the set thickness amount. Pressing the button for longer then one second moves the blade at the fastest travel speed.

Down: Moves the blade arm down. Momentarily pressing the button moves the blade arm the set thickness amount. Pressing the button for longer than one second moves the blade at the fastest travel speed.

Speed

Oscillation: Pressing these buttons increments (+) and decrements (-) the blade oscillation speed.

Advance: Pressing these buttons increments (+) and decrements (-) the blade arm advance speed.

Thickness

Pressing these buttons adjusts the slice thickness. Pressing momentary changes the setting in 1 micron increments. Holding for longer than 1 second causes 10 micron changes.

Travel Window

Reverse Limit: Pressing this button sets the position for the blade arm to start the slice process. The limit can be changed using the blade position buttons at any time to override the limit. Pressing this button again will set the new limit.

Forward Limit: Pressing this button sets the position for the blade arm to stop and return to the reverse limit. The limit can be changed using the blade position buttons at any time to override the limit. Pressing this button again will set the new limit.

Multiple Slice

Start/Stop: Pressing this button starts the process of automatically slicing. Pressing this button once will begin the blade arm moving forward. It will continue until it reaches a forward limit (travel window or mechanical) stop, return to the reverse limit, step down the selected thickness, and begin another slice. Pressing this button during this process will cause the arm to stop and wait for a command. The multiple slice process will continue until the lowest mechanical limit is reached. It will then automatically return to the home position (full up and back).

Zero

Pressing this button resets the slice counter display to read all "0".

Home

Pressing this button at any time will cause the blade to return to its full up and full back "home" position.

Different Mounting Options

Mounting of the specimens can be done directly on our unique tissue pedestal with the option of using the pivot pin (see Diagram 1) or just setting the pedestal flat on the bottom of the tray on a 90° angle (see Diagram 2). In addition, a sample vice holder, with pivot pin can be attached to the tray and mounting blocks used (see Diagram 3). Both devices come standard with the EMS 5000.

The cutting angle can be easily changed and calibrated by loosening the set screw on top of the support arm. The angles between 10-20° can be read off the scale on the side of the support arm.

Diagram One Standard Pivoting Tissue Pedestal

The pivot pedestal arrangement is designed so that the sample can be glued directly to the surface and the angle of the sample can be adjusted relative to the blade.

Diagram Two: Standard Tissue Pedestal

This is the same pedestal as in Diagram 1; however you have the option to mount the pedestal flush to the base on a 90° angle.

Diagram Three: Sample Vice Holder

The sample vice which is provided with the system can be easily alternated with the pedestal. 1.2cm square mounting blocks (provided with the system) or the other pegs are held by the vice clamp.
