A system for controlling a filling level of a reservoir filled with a liquid includes the reservoir configured to be filled with the liquid at least up to a maximum filling level. The system also includes a probe including a probe body, at least a section of the probe body extending, in a height dimension of the reservoir, from a first position to a second position, the first position being lower than the second position, and the second position being above the maximum filling level, and further including a temperature dependent sensor configured to generate a sensor signal based on a temperature at the second position, the temperature depending on the filling level. The system also includes a controller for controlling the filling level of the reservoir depending on the sensor signal such that the filling level is kept constant.

A modular specimen holder (') for high pressure freezing and/or X-ray crystallography of a specimen has a specimen holding element (&#x2032;) and an extension element (&#x2032;) connectable with and separable from each other; the specimen holding element (&#x2032;) including a tubule (&#x2032;) adapted to hold the specimen and a base element (&#x2032;) adapted to hold the tubule (&#x2032;), wherein a distance from a bottom of the base element (&#x2032;) to a top of the tubule (&#x2032;) is a first distance (d); the extension element (&#x2032;) being connectable with the base element (&#x2032;), wherein, when the extension element (&#x2032;) and the base element (&#x2032;) are connected with each other, a second distance (d) from a bottom of the extension element (&#x2032;) to the top of the tubule (&#x2032;) is larger than the first distance (d).

An apparatus for staining sample sections, comprising: a chamber that is adapted for fastening sample sections therein; and a pump that is adapted for pumping liquids through the chamber. The chamber has an inlet and an outlet. The inlet can be connected to at least one reservoir of a staining liquid via inlet lines that are controllable by valves. The inlet lines are formed at least in the region of the associated valves by means of elastic hose lines, and the valves are formed as hose pinch valves. This apparatus minimizes or eliminates contaminations arising from staining processes for thin sections that are in particular prepared for examination in an electron microscope.

A vibrating microtome and measuring device for measuring the transverse offset of a vibrating knife comprises a light barrier into which the knife is placeable and a control application signal (pklo, pkhi) that describes the time course of the vibration of the knife and an electronic measurement system of the measuring device measures the coverage of the light barrier as an oscillating signal (tpm), and determines the transverse offset from the signal values at points in time that are defined by the control application signal.

A cooling chamberfor a microtomeis disclosed. A knifehaving a cutting edgeis arranged in the cooling chamberopposite a sample holderhaving a sampleretained therein. The microtomefurther possesses a stereomicroscopehaving an optical system, the optical systemdefining an optical axis. The region of the sampleand of the cutting edgeof the knifeis observable with the stereomicroscope. There is mounted in the cooling chamberan illumination systemthat emits lightand is directed onto a surfaceof the knifein such a way that the lightreflects from the surfaceparallel to the optical axis
