An apparatus for collecting imprinted cassettes and/or specimen slides for histological or cytological preparations comprises a motor-driven lifting platform () having panels () arranged one above another and adjustable as to height by way of the lifting platform (), for collection of the cassettes and/or specimen slides.

Apparatus for collecting imprinted cassettes and/or imprinted specimen slides for histological or cytological preparations

A panel () for receiving cassettes () and/or specimen slides () for histological or cytological preparations is embodied in rectangular fashion with two longitudinal sides (), a first narrow side () and a second narrow side (), and comprises a base () as support for the specimen slides () and/or cassettes (). Peripheral side walls () are provided on both longitudinal sides () and on the first narrow side ().

Panel for receiving cassettes and/or specimen slides for histological or cytological preparations

A delivery device ( ) for cassettes and/or specimen slides for histological preparations in a printing system ( ) is described. The cassettes and/or specimen slides are in each case arranged one above another in stack magazines ( ), a control device ( ) being provided for removal of a cassette and/or specimen slide from the stack magazines ( ). The improvement comprises a drive shaft ( ) having a motor ( ) for at least two stack magazines ( ), and the motor ( ) is connected to the control device ( ).

Delivery device for cassettes and/or specimen slides for histological preparations in a printing system

A method and an apparatus for printing onto plastic cassettes for histological preparations and/or onto glass specimen slides for microscopic thin sections are described, in which a computing device ( ) is provided to control the printing device ( ), and the printing device ( ) comprises an inkjet printer for printing onto the cassettes and/or specimen slides. The ink is pre-dried by way of a hot-air drier ( ) and completely dried by way of a flash device ( ).

Method and apparatus for printing onto cassettes or specimen slides for histological preparations

The invention relates to a microtome (,) for producing thin slices for microscopy, which is provided with a base (,), a blade holder (,) for holding a cutting blade (,) and an object holder (,) for holding the object (,) to be cut. Cutting occurs in a plane by a relative movement between the object (,) and the cutting blade (,) To produce the relative movement, a rotating component (,) is provided with a drive motor (,), wherein the rotating axis of the rotating component (,) is arranged obliquely to the base (,), and a feed slide (,) is provided with a linear guide for setting the slice thickness. The structure of said feed slide (,) is such that it is removable via a feed motor (,) and a control circuit (,) connected thereto.

Disc-microtome

A clamping device for a blade-shaped cutting knife of a microtome. The clamping device comprises a base part having a recess, a knife receptacle, an eccentric rod, and setscrews. The knife receptacle includes a blade rest and a pressure plate which is received in the recess of the base part. The eccentric rod is rotatably mounted in the base part and is provided for clamping the cutting knife between the pressure plate of the knife receptacle and the blade rest. The setscrews allow for both lateral and vertical movement of the pressure plate. Thus, by adjusting the setscrews, the edge of the pressure plate may be aligned with the cutting edge of the knife and variation in the thickness or geometry of cutting knife blade may be accommodated.

Clamping device for a blade-shaped cutting knife of a microtome

A rotary microtome includes a crank mechanism for moving an object carriage up and down in a vertical path and a drive mechanism for driving the crank mechanism. The object carriage has a receptacle for a specimen holder. A mass-balancer balances the moveable masses of the microtome. The mass-balancer has a pretensioned, adjustable spring element and a pivotably mounted lever for compensating different inertial forces of the microtome in combination with the spring element. A drawing element connects the lever to the object carriage. The mass-balancer is indirectly connected to the drive mechanism by the drawing element.

Rotary microtome with a crank mechanism

A microtome knife holder comprises a support element provided on the base connected to a microtome and at least one jaw for clamping the knife that is adjustable along a rail of the support element in the same direction as the cutting edge of the knife and releasably securable on said supporting element at a desired location. The guide means if formed of a prism rail of substantially dovetailed profile, a slotted foot portion of the holder is formed with a matching complementary profile and compressible by means of at least one screw engaging around said prism rail. Different holders, usually for different types of knives, can easily be slid on or off the rail. A quick release clamp and edge guard are also disclosed.
