The TES 99 is a flexible, reliable paraffin embedding center, consisting of three different units for heating, dispensing and cooling of tissue samples in paraffin. The units can be arranged individually in order to optimize the work process for personal preferences, e.g. to optimize for left-handed operation. Each unit works independently with own temperature control, and can therefore be used as a single device in the laboratory. The work surfaces are designed ergonomically to prevent fatigue after long periods of use.
