ASI Reagent Reservoirs Multichannel Trays ASI’s multi-channel solution reservoirs are designed for use with all multichannel pipettes. Standard 4 channel, 8 channel, 12 channel and various special purpose pipettes are all compatible with these disposable, polystyrene reservoirs. To facilitate easy, dripless pour-off of unused reagents and solutions, all versions have indented “spouts” in each corner. Bottoms are formed with a sharply tapered “V” shape to minimize waste and reagent consumption. B/ TROUGH Easy open, hassle free white tear strips are featured for easy handling. Stacked basins will not "stick" to each other.
