Hirschmann burettes

A burette is a calibrated glass tube with a scale and a ground-in stopcock at the lower end, which is used for the quantitative measurement of small liquid volumes in titration. There are different types and shapes of stopcock (e.g. with straight stopcock, with side stopcock or side valve stopcock). We carry a wide range of different burettes from Hirschmann, including micro burettes or digital burettes as well as titration apparatus.

Hirschmann pipetus® - pipetting aids for laboratories

Pipette holders for pipetus from Hirschmann combine many years of experience, innovative technology and high-quality materials. Pick-up and dispensing of the medium is done at the push of a button. Exact meniscus adjustment is enabled by fine dosing valves with valve pins made of ceramic compound. The valves are wear-free and of the highest chemical resistance. For both filling and blowing out, the pumping and suction speed can be selected precisely and continuously within five precisely coordinated performance levels. The integrated colour display shows pipetting mode, speed levels and battery charge status. The battery is charged contactless and microprocessor-controlled in an inductive charging station. The ergonomically designed pipetus supports fatigue-free work.

Hirschmann Liquid Handling: Dosing devices and dispensers

With ceramus®, the many years of Hirschmann experience in liquid handling is effective through perfection down to the last detail. Step gauges and digitally locking volume settings ensure constantly precise and operator-independent reproducible volume dispensing. The dispensing piston made of high-purity aluminium oxide ceramic and the DURAN glass cylinder guarantee maximum chemical and thermal resistance for Hirschmann ceramus products and dispensers. This ensures permanently reliable dimensional accuracy of the volume-determining parts and provides superior ease of use. The piston fits perfectly, can be operated easily with little effort and retains its functional reliability throughout its entire service life. The high-quality materials of all media-carrying parts allow the ceramus to be used in a temperature range of 4 °C to 50 °C; the device can be steam-sterilised at 121 °C.
