A versatile general purpose system with two removable/interchangeable blocks and a comprehensive specification to suit most dry block heating applications in the laboratory.

The outstanding performance of the QBD / QBH series is based on advanced digital temperature control combined with high quality, precision-engineered blocks providing excellent thermal contact. The result is accurate, reproducible and safe heating of your samples.

The general purpose QBD series comprises 1, 2 and 4 block models, while the 2-block QBH2 model offers higher performance for more demanding applications. The units are constructed in streamlined coolwall aluminium and chemical resistant plastic. The sloping fascia ensures clear visibility both for set-up and in operation.
