29 Leica VT1000 A 5. Operation Fig. 42 5.2.2 Adjusting the specimen and blade Positioning the specimen in the specimen holder You can adjust the lateral position of the speci- men in order to attain an approximate centering of the specimen in the specimen tray.
30 Operating Manual V 1.1 – 01/2010 5. Operation In some cases, e.g. for large specimens, it is necessary to move the blade holder ( 50 ) on the mounting bar.
31 Leica VT1000 A 5.2.3 Adjustable sectioning window The VT1000 A features an adjustable sectioning window that you can use you speed up the process of making series sections.

33 Leica VT1000 A 5. Operation 5.2.4 Adjusting the specimen height The thi ckn ess of s ecti ons gen erat ed i s co ntr olle d by the rai sing of the sp ecim en i ncr emen tal ly. Since the sectioning blade remains stationary along the vertical axis, the increment by which the specimen is raised correlates to the section thickness.
34 Operating Manual V 1.1 – 01/2010 5. Operation The Leica VT1000 A offers a wide variety of options for sectioning fixed and unfixed tissue samples of plant or animal origin. It employs a vibrating blade principle, which allows sec - tioning without freezing or embedding.
35 Leica VT1000 A When the instrument is switched on for the first time, the blade is automatically moved back in operating state "B" and stopped in state "C".
36 Operating Manual V 1.1 – 01/2010 As a result of the great variety of specimen types, sizes, shapes, states and preparations, etc. that can be encountered while sectioning with the VT1000 A, it is not possible to provide specific recommendations for parameter settings.
37 Leica VT1000 A 5. Operation Direct mounting Specimens rigid enough to be held firmly in the specimen holder without damage may be clamped directly. Keep in mind that excessive clamping forces on the jaws of the specimen holder can cause ten- sion in the specimen.
38 Operating Manual V 1.1 – 01/2010 5. Operation The surfaces onto which the specimens are attached must be clean, dry and free of adhesive residue from previous applications.
39 Leica VT1000 A 5. Operation If the specimen requires a larger surface, you can use specimen tray (39053744) or the deluxe specimen bath (39053745). Specimens small enough to fit on a surface of a specimen mounting block can be affixed directly. The specimen mounting block is then clamped into the jaws of the specimen holder for sectioning.
40 Operating Manual V 1.1 – 01/2010 Be careful when handling the dispos - able blades or sapphire knife. The cutting edge is extremely sharp and can cause serious injuries. Before inserting a blade, the specimen to be section should be attached to the specimen plate (clamped into place or affixed) to prevent injuries.
41 Leica VT1000 A 5. Operation The speed and amplitude should be set to "0" initially. Then, advance the blade until it almost touches the specimen. For this purpose, briefly push the direction switch upwards. With the sectioning blade close to the specimen, their relative heights may be gauged approximately.
42 Operating Manual V 1.1 – 01/2010 5.5 Preparing the specimen bath The purpose of the specimen bath is four-fold: to lubricate the blade dur - ing the sectioning operation, to prevent the specimen from heating up or drying out, to increase or maintain desired features of the specimen and to allow effortless removal of the fragile sections.
43 Leica VT1000 A After the specimen has been trimmed to create a flat specimen surface, the preparations for actual sectioning can be carried out. The procedure consists of generating a few sections at the final parameter settings and section thickness.
44 Operating Manual V 1.1 – 01/2010 Sections generated may be retrieved from the specimen bath by various means. For microscopic applications, the section may be delivered to a glass slide by aspirating the section with a small glass dropper if doing so does not damage the specimen.
45 Operating Manual V 1.1 – 01/2010 6. Cleaning and Maintenance 6.1 Cleaning the instrument • Always remove the bladebefore detaching the blade holder from the ins.
46 Operating Manual V 1.1 – 01/2010 Specimen bath area After sectioning is completed, the specimen bath, specimen holder and sectioning blade holder should be cleansed of any bath solution residue. Any water-soluble solvent may be used unless it corrodes parts made of polypropylene or nitrile rubber.
47 Leica VT1000 A 6. Cleaning and Maintenance When used normally, the Vibratome VT1000 A requires only standard maintenance. To ensure trouble-free operation of the instrument over a long period of time, the following is recommended by Leica: • Thoroughlycleantheinstrumentonadailybasis.
48 Operating Manual V 1.1 – 01/2010 6.3 Replacing components 6.3.1 Fuse If the instrument fails to function completely, first check for power avail - ability at the power outlet. The instrument fuse (s) located at the rear of the instrument should be checked next.
