Lachat Instruments’ AP300 Discrete Analyzer will heighten the productivity of your laboratory. With pre-programmed methods, and pre-prepared reagents, you can save time and money. Other terrific advantages of discrete technology include:
- Simple setup and less operator training
- Minimal maintenance and downtime
- Ease of use due to automation of manual methods
- No clogging, no pumps and no tubes
- High throughput, reduced reagent consumption, and less batching
- Guaranteed results with Lachat prepared reagents
Lachat Instruments’ AP300 Discrete Analyzer surpasses the performance of other discrete analyzers with the following key features:
- Increased standard and reagent positions
- Separate pipets for reagents and samples
- Pre-programmed methods
- Support you can trust from the most knowledgeable technical support team in the industry
Cadmium Reduction
Lachat now offers a unique solution for the determination of Nitrate by Cadmium reduction:
Lachat's new and patent pending Cadmium Cup is an innovative solution that eliminates the issue of fouling and therefore minimizes maintenance associated with the regeneration of cadmium columns. Typical columns may need to be regenerated every 4 to 10 samples when wastewater samples are being run, incurring at least a 15 minute down time with each regeneration. With the Cadmium cup, sample is simply added, mixed, reacted and analyzed at a maximum efficiency for each and every sample.  | AP300 Methods *  | Chloride |

| How the AP300 Analyzer Works (Single Reagent) | 1 | Before adding the sample, reagent is transferred into a reaction cuvette and brought to temperature. | | 2 | The reagent in the cuvette is immediately measured by the built-in photometer to obtain a Reagent/Cuvette Blank. | | 3 | The sample is transferred to the reaction cuvette and mixed with the reagent to start the reaction. | | 4 | Samples are measured every 24 seconds. | | 5 | The reaction cuvettes are immersed in a liquid bath at 37 °C and are automatically washed for a non-stop operation. |
