AP3900 Laboratory Robot The AP3900 Laboratory robot is designed for fully automated water analysis, including sample preparation. Even when a digestion is needed. The Basic version contains COD, total P, total N, Ammonium, Nitrate and Nitrite. This unique product processes the critical parameters of COD, total P and total N in parallel (Multi) using our well established, pre-programmed Hach APC cuvette tests. The control software ensures the optimal sequence for processing all samples to minimise total time to results through sample preparation, digestion of complex samples, waiting times and measurement. Additional samples can be added at any time, even when the sequence is running and the current status of the analysis is accessible any time with a simple mouse click. Rapid yet simple even untrained users are able to enter all necessary information to the system due to the easy-to-use software. • Saves time and costs • Increases productivity and flexibility • Highest precision and accuracy due to automated procedures • Parallel execution of different samples and methods • Reliable by complete traceability of results
