Laboratory Products 37 Why Infrared Radiation Heating?
Infrared radiation heating refers to the spectrum between 0.7um-100um of light waves, emission and transmission accompanied by obvious, directional energy transmission. The energy transmission does not need any media, even in vacuum space. The infrared heating uses an electromagnetic wave with a wavelength of 2.5 to 15 um. This speed is much higher than the rate of conduction and convection. Thanks to this radiation heating technology, Wiggens hotplate and stirrer can be used for speedy heating up for various shaped vessels including round-bottom flasks, and the solution inside can be heated up to a maximum temperature of 450°C in a very short time.
The hotplate and stirrer, with its advanced infrared radiation technology, is characterised by direct, clean and safe heating compared to oil heating. The high infrared permeability ensures that the heating energy is transferred quickly and with very limited loss, i.e. it heats liquids fast and thus saves time and energy. PID control or advanced ICC technology enable good temperature stability. If the Pt-100 sensor is connected, temperature-controlled work with stability of ± 2°C can be reached in most applications.

Mixer Mill for Biological Applications and Cell Disruption
Mixer mills are widely used for homogenising biological samples such as tissue, liver, muscle, plants, corn or sputum. For cell disruption via bead beating mixer mills are also the perfect solution.
Retsch’s new Mixer Mill MM 500 vario is a versatile bench-top unit which provides ultimate performance with maximum flexibility for sample homogenisation. It accommodates adapters for different single-use vials of 0.2 ml/1.5 ml/2 ml/5 ml.
Depending on the tube and the type of adapter, 5-10 tubes can be inserted per adapter, resulting in the following maximum vial capacity per batch: 50 x 1.5 or 2 ml (or 60 x 0.2 ml) or 20 x 5 ml.
Typical grinding/homogenising processes of biological materials take less than 2 minutes. Cell disruption with a good reproducibility and efficiency takes 20 sec to 5 min, depending on the cell type. Cryogenic grinding in single-use vials can also be a suitable way to pulverise tough or temperature-sensitive samples in the MM 500 vario.
