Control Keypad

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 then 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 then 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 the home position.

1. Slice Counter/ Thickness Displays a count of the number of slices from a user defined zero reference. When prompted, displays the slice thickness setting in microns.

2. Oscillation

Displays the speed of the blade oscillation in bar graph form. Each line of the graph represents a speed.

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 1 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 2 Standard Tissue Pedestal

This is the same pedestal as in diagram one; however you have the option to mount the pedestal flush to the base on a 90˚ angle

Diagram 3 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.

Pivot Pin Pivot Pin Pivot Pin 3. Advance

Displays the speed of the blade advance in bar graph form. Each line of the graph represents a speed.
