Polypropylene solution basin/reagent reservoir has a standard 50 mL basin on one side and 12 individual 5 mL basins on the other side. Wells are angled both downward and outward, guiding multichannel pipettor tips toward a centered position, which helps to avoid contamination and waste. Imprinted indices identify samples; loose-fitting lids prevent evaporation and contamination.
 
Non-sterile. Pack of 25 reservoirs and 25 lids.
