Reagent Refill System

Innovadyne Technologies offers the Recirculating Reagent Refill System for HTS and other applications that require dispensing up to four reagents to multiple plates. The reagent refill system refills the reagent reservoir automatically from separate reagent sources, maintaining a constant liquid level in each. This eliminates time-consuming manual pipetting and reagent level monitoring, and enables integrated automation and temperature control. The system includes an RS232 port that allows users to fill the reservoirs in a "just in time" fashion.

Each reservoir is supplied with fresh reagent via an inlet tube, and drained of excess via an outlet tube, both connected to channels on the pump. The excess can either be deposited into the same reagent receptacle from which it was aspirated (see diagram), or discarded as waste. Reagent heating, chilling or mixing is easily achieved using off-the-shelf peripherals such as hot plates, stir bars, and chillers to control the conditions of the reagent source.
