- Page 42 The radiation applied in the KERN DAB penetrates mainly the sample in order to be transformed inside it into heat energy that is, warming from the inside to the outside. A minor amount of radiation is reflected by the sample, a reflection that is less in dark samples than in light-coloured ones.
- Page 43 For liquids, pastes or melting samples we recommend to use a glass fiber filter. The glass fiber filter has the following advantages: • even distribution thanks to capillary attraction • no formation of droplets • fast evaporation due to a greater surface DAB-BA-e-1511...
- Page 44 In the course of this arise two opposed requirements: The lighter the originally weighted in quantity, the easier it is to achieve shorter drying times. However, the heavier the originally weighted in quantity, the more accurate a result. DAB-BA-e-1511...
- Page 45 The glass fibre filter is also useful as a protection when splashing materials are dealt with (each splash falsifies the final result). You will find examples taken from actual use in our application manual, available from the KERN home page (www.kern-sohn.com). DAB-BA-e-1511...
