TKA 540 Line

A high performance and profitability line, due to simultaneous action of 4 needles that distribute 96 samples in the microplate within a very short period. This line includes three models—TKA 543 that operates 3 microplates, TKA 544 that operates 4 microplates and TKA 546 that operates 6 microplates. In order to avoid contamination each needle is fitted with its own membrane pump for internal washing purpose. The operator can freely choose up to a maximum of twelve assays to be included in the Profile to carry out. These units are an adequate solution for medium-size laboratories.

TKA 580 Line

TKA 586 with 6 microplates and TKA 589 with 9 microplates are two top models of the new line and are particularly adequate to perform routine screening tests in laboratories having huge workloads and in blood banks, especially due to the use of eight needles. A whole microplate is processed in approximately 5 minutes (100 μl in individual quotas). Each incubator can freely programmed at an individual temperature. Futhermore, TKA 589 can be provided with the “STAT function" option that allows samples and new analysis, if so required, during the session.
