    8. OPERATION OF MICROTOME 8.1 INSERTION AND ORIENTATION OF KNIFE Activate hand wheel lock. Loosen the knife fixation by turning two screws in front of the knife holder counter clockwise Remove/Insert knife Adjust knife height by turning the wheels on the left and right side of the knife holder base.
  • Page 22 8.2 INSERTION AND ORIENTATION OF DISPOSABLE BLADE Activate hand wheel lock. Remove finger protection. Loosen the blade fixation by turning the right lever counter clockwise. Use the blade ejector to remove the blade. Remove/Insert blade from right side. Loosening of blade fixation and insertion of new blade. Tighten the blade fixation by turning the right lever clockwise.
  • Page 23 To change the cutting angle, loosen the blade holder by turning the right lever on the blade holder base counterclockwise. Tilting the blade holder to the sample increases the cutting angle, tilting the blade holder away from the sample reduces the cutting angle.
  • Page 24 8.3 SPECIMEN MOUNTING The instrument is equipped with 24 freezing positions. The temperature is approx. 10 °C lower than the actual cryochamber temperature. In order to prepare a specimen for sectioning, place the specimen holder on a freeze point, add some drops of embedding medium (e.g.GSV1) on the holder and carefully press the object on top.
  • Page 25 8.5 SPECIMEN ORIENTATION ADJUSTMENT Turn hand wheel to its highest position and activate the hand wheel lock. 1. For a new sample orientation, loosen the fixation lever on the left side of the sample holder counterclockwise. 2. To adjust the orientation, swing the right orientation screw.
  • Page 26 8.6 FAST APPROACH TO SPECIMEN Press to move the knife holder base towards the sample. Press to move the knife holder away from the sample. 8.7 SLOW APPROACH TO SPECIMEN Press to move the knife holder base slowly towards the sample. 8.8 THICKNESS ADJUSTMENT FOR TRIMMING To change the trimming settings, press continuously and press...
  • Page 27 8.11 MANUAL CUTTING Deactivate the hand wheel stop. Release the finger protection. Turn hand wheel evenly clockwise. A counter clockwise movement will also result in cutting and incremental advance of the specimen. Approach specimen either by trimming or slow approach. TUE 13:05:05 Set the required section thickness.
  • Page 28 8.12 ANTI-ROLL PLATE Each instrument is equipped with an anti-roll plate. To adjust the anti-roll-plate vertically, turn the wheel on the base to the left (towards the blade) or to the right (away from the blade). To remove the slices, swing the anti-roll-plate to the left.
  • Page 29 8.13 TIPS AND TRICKS It is common knowledge that the temperature of the cryostat plays an important role in the quality of the tissue sections obtained. Each type of tissue needs a different temperature as shown in the following list. The temperature ranges indicated in the table below are approximate values and may require adjustments for individual tissues.

  • Page 33 9.4 AUTOMATIC/MANUAL DEFROST For optimum performance of the cooling unit a low thermal contact resistance at the cooling lamella is required. Upon frequent use of the instrument moisture will condensate and freeze on the surface of the cooling lamella and increase the thermal contact resistance.
  • Page 34 9.5 SHUTDOWN AND CLEANING THE DEVICE It is highly recommended to defrost the instrument at least every 6 months. If the instrument is used regularly in warm tropical climate a more frequent complete defrost might be necessary. The unit should be defrost for a minimum period of 48 h, better over the weekend.
