General Chemistry Lab

The basis of modern analytics

Traditional chemical methods are used in general chemistry laboratories. Although analytics today predominantly relies on modern equipment, the traditional methods still have their raison d'être. Understanding the principles of thin-layer chromatography, for example, makes it easier to understand how other, often more complex analytical devices work and to use them in a targeted manner.

The methods of general chemistry require little equipment, can be carried out quickly and often surpass instrumental analysis in terms of achievable accuracy. However, these methods can hardly be automated and often depend heavily on the experience of the person carrying them out.

Traditional methods continue to play an important role in teaching. They are also still generally in use in research projects.

Conductometer, for measuring the conductivity of a solution

Free access for researchers after instruction
On request, assistance with special analytical questions in the field of research and teaching

Analytical balances
For gravimetric determinations, for preparing solutions of defined concentrations
Burettes, fully automatic titrator Ti-916 from Metrohm
With these devices, dimensional analytical determinations can be carried out quickly and precisely.
pH meter
For exact measurement of the pH value of a solution
Conductometer
For measuring the conductivity of a solution
Karl Fischer titrator
The water content of a sample (e.g. water content of a solvent) can be determined. With an additional device, this can also be used for water-containing, solid samples such as wood, grain, etc.
Nabertherm muffle furnace up to 1300°C
Here samples can be incinerated or digested for analysis, and metallurgical work steps can also be carried out.
UV/VIS spectrometer from various manufacturers
A dilution series can be used to set up a calibration curve for a specific substance, which can then be used to determine the concentration of this substance in drinking water, for example
