Asynt DrySyn MULTI-M reaction block is a modular, single or multiple reaction system that can be placed on virtually any heating block, circular or square. Every detail of the system aids the chemist, from the modular nature and high contrast finish to the 10 to 250 ml flask range and acceptance of standard glassware, vials and tubes. The instrument is made from anodized aluminum, which combined with its compact size, allows high heat and magnetic field transfer. Up to 3 10-ml to 250-ml round bottom flasks sit within the confines of the hot plate and can be heated to 250 C while receiving equal stirring. Twelve reactions at a time can be carried out using vials or tubes, again all receiving equal stirring and heating. Staying within the confines of the hotplate means that even viscose solutions can be evenly stirred and heated. Single reactions can be placed in a central position on the instrument to maximize heating and stirring efficiency. The clamp can support all three flasks separately to the hotplate, allowing rapid removal of the heat source from the reactions if required.
