5 1.2 Usage According to its Specification The CUT 4055 and CUT 4060 rotary microtomes are manually operated instruments for use in all work involving paraffin wax and solid cut microtomology within the disciplines of biology and medicine, and within industry at large. The specimen can be moved back and forth by means of the coarse wheel mechanism so as to attain rapid advance of the specimen in relation to the knife during cutting. The micro-drive mechanism enables feed settings to be made within the range of 0,5 to 60 microns. The user friendly throw-away blades and universal knife holder with its integrated knife guard enables trouble-free clamping and setting of the knife blade. The integrated safety device to prevent any collisions occurring, which is incorporated in the micrometer mechanism, disables any adjustment to the feed setting being made upon reaching its maximum setting. The CUT 4060 rotary microtome is equipped with an electronic cutting counter, which indicates the total number of cuts made. To prevent damage occurring to the knife or the specimen, the rotary CUT 4060 microtome imparts an action of slight retraction of the specimen by approx. 80 microns during the motion of advancement. Likewise, a three-position trimming assembly is also incorporated (10, 20 and 30 micron trimming). GmbH - Company for Manufacture and Export of Laboratory Equipment 5

7 1.6 Brief Description of Use, Function, and Sequence Use The CUT 4055 and CUT 4060 rotary microtomes are manually operated instruments for use in all work involving paraffin wax and solid cut microtomology within the disciplines of biology and medicine, and within industry at large. Function and Sequence Manually rotating the handwheel on the rotary microtome translates into vertical movement of the fixture holding the specimen. To produce the cut, resharpenable knives or throw-away blades are used, which are adapted and attached to the various knife holders. A microtomic cut is made during the downward motion of the specimen (cutting action). By continuing to rotate the handwheel further in a clockwise direction the specimen starts to rise again in its return motion. The cutting feed can also be set by means of the three-position trimming assembly (only available on the CUT 4060 model). The selected feed for the thickness of cut is instigated at top dead center. Rapid advance of the specimen towards the knife is achieved by means of the coarse feed mechanism. A universal clamping fixture for holding a variety of specimens is provided. As a result, simple alignment to the plane of cut is possible using the facility for orientating the specimen. The various knife holders enable trouble-free use of a variety of knife types and thereby provide facility for making adjustment to suit the application in question.

23 6. Operation 6.1 Preparation, Orientation, and Alignment of the Specimen Prior to starting to cut the specimen, the specimen must be suitably prepared and embedded and encapsulated in an appropriate medium. Various molds and plastic cassettes are used for encapsulation purposes. By using the microtec adapter system, the specimen can be aligned to the plane of cut. 6.2 Commencing the Cutting Operation Macro positioning of the specimen in relation to the knife cutter is accomplished by moving the base of the knife holder, or by operating the handwheel of the coarse feed drive (Fig. 2.11). With continued operation, cutting of the specimen commences up to the required depth of slice. The residues of the cut specimen so produced must be wiped away from the knife in an upwards direction from underneath using a brush. Important! Do not touch the knife with your fingers! 6.3 Instructions for Producing Sliced Microtomic Sections of the Specimen The following aspects are to be heeded in order to produce effective sliced microtomic sections of the specimen: always use a sharp knife, as wear occurs at the point of cut, slide the knife to the left or to the right, in order to be able to continue working with a sharp section of the knife, always keep the front and rear face of the knife clean. It is important to thoroughly remove any traces of paraffin wax. GmbH - Company for Manufacture and Export of Laboratory Equipment 23

24 6.4 Cutting Action The cutting action of the rotary microtome is generated by rotating the handwheel (Fig. 1.1) in a clockwise direction. The cut is accomplished on the down stroke and retraction on the upwards directed stroke by further rotation of the handwheel (Fig. 1.1) in a clockwise direction. 6.5 Handwheel (Fig. 1) The handwheel (1) is integrated in the casing of the microtome (Fig. 1). The position of the handle (2) corresponds to the vertical position of the specimen. The handwheel locking device is situated on the handwheel (1). Releasing the handwheel locking device Press down the knob (refer to illustration) Locking the handwheel (1) Press the handwheel locking device (refer to illustration). Handwheel (1) engages in one of the 24 locking positions. Important! For personal safety, the handwheel should always be locked in the upper region of vertical travel when exchanging specimens. 6.7 Coarse Advanced Drive To rapidly alter the distance between the knife and the specimen, the rotary microtome is equipped with a coarse advancement drive (11). The specimen fixture can be moved forwards or backwards horizontally by the handwheel for the coarse advancement drive (11). GmbH - Company for Manufacture and Export of Laboratory Equipment 24

25 6.8 Friction Clutch on the Coarse Advanced Drive Mechanism On reaching the front and rear positions of the specimen feed, a friction clutch built into the coarse advanced drive prevents the blocking of this coarse advanced drive. As soon as an audible engagement is triggered by the coarse drive, the feeding operation of the specimen stops. Upon rotation of the handwheel of the coarse advanced drive (11) in the opposite direction, the feeding motion is restored. If the feeding motion is not restored by this procedure, the handwheel of the coarse advanced drive mechanism (11) must be pressed inwards against the casing. Only a short forward or backward movement is needed to ultimately activate the feeding motion. Important! Avoid touching the specimen or the specimen holder containing the knife when operating the handwheel of the coarse advanced drive mechanism. 6.9 The Handwheel of the Coarse Advanced Drive Mechanism (11) The handwheel of the coarse advanced drive mechanism (11) is integrated in the casing (Fig. 2) 6.10 Collision Protection Device On the specimen feed system reaching its forward terminal position, a red mark is visible on the cylinder (12). From this mark there is a further distance of adjustment of max microns available. A second red mark then becomes visible, and the cylinder must be rotated back by means of the handwheel of the coarse advanced drive (11), before further cuts can be made. Important! As soon as the remaining distance of adjustment of 2500 microns is exceeded, the preselected thickness of cut is disabled by the in-built collision protection device. Any automatic adjustment by rotating the handwheel is now inactivated. GmbH - Company for Manufacture and Export of Laboratory Equipment 25
