Combinatorial chemistry, also known as combichem, is a technique used in drug discovery to create libraries of structurally related compounds. A library is generated by synthesis with a chemical reactor system or by computer-based modeling of compound combinations. When undertaking combinatorial chemistry consider reagents, buffers, resins and standards.
CR 2200 is ideal for anyone who needs to perform routine water analysis tests with small sample amounts, as 5 programs are available for digestion of 12 sample cuvettes at 212, 248 and 298.4 °F (100, 120 and 148 °C).
In addition, you can program the CR 3200 to carry out 8 of your individual digestions at freely selectable temperatures up to 338 °F (170 °C).
CR 4200 is the right choice for anyone who needs to perform multiple tests simultaneously, such as COD (298.4 °F/148 °C) and total-N (248 °F/120 °C), as the two thermoblocks for 12 cuvettes each can be controlled separately. It also has memory for 8 of your own user-defined programs with free temperature selection up to 338 °F (170 °C).
