Infra-red heat rays provide soft heating and optimal temperature maintenance A big "NO" to heating blankets, jacketed vessels and thermal circulating baths X X Prevents natural cooling and a complementary cooling is required Restricted view into the vessel Very expensive and voluminous More heat is dissipated outside the vessel (to your lab) than transmitted into the medium Heat transmission occurs mainly by slow and inefficient thermal conduction How infra-red radiation heating is efficient? Precise temperature control at low cost No hot spots at any medium volume Natural upwards convection even without any agitation Perfect visibility into the vessels Imitating soft sun-like way of heati ng Heats up and cools down quickly Convenient & Safe - No cables, tubings, connectors, circulating water supplies
