Rotary microtome
The new Lcica RM 2165 automatic, heavy-duty microtome has an advanced step motor that permits an exact specimen feed and reproducible sectioning results. Features include 70 mm vertical stroke length, unique step trim function, and programmable specimen retraction. Technical features include a handwheel rocking sectioning mode; the motorized specimen feed can be linked to change the handwheel t...
متن کاملA microtome knife guard.
The base sledge microtome presents a hazard to the operator due to the length of blade that is exposed. Manipulation of the carriage requires hand movements close to the knife edge and serious lacerations may result. A simple, effective guard has been devised, suitable for knives which have screw holes for handles at both ends. It consists of two perspex end-pieces (Fig. I), attached to the kni...
متن کاملThe sharpening of microtome knives.
The regular production of a satisfactory edge on a microtome knife for the cutting of sections as thin as 2 u, which are free from scores and other blemishes, is a serious technical problem in histological laboratories. Eyen when a good edge is produced on a knife, its life is generally limited because contact with any hard material in the specimen may damage the delicate edge, causing it to sc...
متن کاملThe Microtome for Native Tissues
This article describes the design of a microtome for sectioning of a native tissue. The base of the microtome is developed on the scheme of the rotary microtome. Using the microtome it is possible to prepare slices of animal and plant tissues of 100–400 μm thick. This microtome may be used for preparation of native tissues slices in cell physiology and microscopy.
متن کاملAn Improved WAGNER-WHITIN Algorithm
We present an improved implementation of the Wagner-Whitin algorithm for economic lot-sizing problems based on the planning-horizon theorem and the Economic- Part-Period concept. The proposed method of this paper reduces the burden of the computations significantly in two different cases. We first assume there is no backlogging and inventory holding and set-up costs are fixed. The second model ...
