| ARS Series Interface Options |
| Fraction Collector |
The ARS delivers samples to sterile vials in a fraction collector for post run analysis. Using Peltier temperature control, the fraction collector maintains temperature in a range of 4°C to 37°C. The standard rack supports 30 vials. Custom racks are available to meet individual requirements. |
| Nutrient Monitors |
The ARS supports nutrient monitors from several vendors that can provide analysis for glucose, lactate, glutamate, glutamine, sucrose, ammonium, potassium, ethanol, lactose, methanol, and chlorine. |
| HPLC Systems |
HPLC is one of the most widely used analytical tools in the biotech industry. The ARS can deliver sample to any HPLC system that supports a simple digital interface. Dependent on the operation, the ARS can function as the master controller or as a slave to the HPLC. |
| Cell Counters |
Groton Biosystems is developing interfaces to industry-standard cell counters to ensure rapid delivery of samples as well as the recording and handling of the results. |
