PEQIDAF is a unit for the performance of daphnia acute toxicity or reproduction tests under flow through conditions. It insures constant test concentrations during the whole duration of a test and considerably reduces the man hours required for the daily renewal of the test solutions in replicate.

This apparatus consists of a PEQITOX 3 Modified Mount & Brungs Proportional Diluter completed by a dispenser of feed (algae and vitamins), a distributor for the even distribution of the 5 test solutions, vehicle control and fresh water control to up to 10 replicates and an exposure chamber capable to accommodate up to 70 beakers of 100ml volume. The exposure chamber is equipped with fluorescent light, automatic day/night simulation system and dimmer.

The unit is designed to be placed in a temperature controlled room. If such rooms are not available a cabin maintaining the temperature of the complete unit at 18 - 25 ± 0.5 C° can be supplied as an option.
