Adopting a standard ANSI / SLAS footprint - INTEGRA 96-well and 384-well reagent reservoirs (100 ml and 300 ml) are fully compatible with all liquid handling systems including the VIAFLO 96 and VIAFLO 384 Handheld Multichannel Electronic Pipette. 96 and 384 individual pyramidal indentations in each reagent reservoir allow maximum liquid recovery when using the VIAFLO 96 or VIAFLO 384 electronic pipette as well as other platforms. VIAFLO multichannel reagent reservoirs are both economically and environmentally friendly because users can reuse the reservoir base and dispose of the reservoir inserts. These reagent reservoirs are also designed to nest within one another without sticking and come in compact, space-saving packages. Features and benefits: - Holds the disposable reservoir securely during use. Because the base can be reused and only the insert is tossed away, less plastic is wasted. - Molded into each corner, convenient pour back spouts control liquid flow and allow you to neatly and easily return excess fluid to a source container - if your protocol allows. - 96 or 384 individual pyramidal indentations allow for maximum liquid recovery when using VIAFLO 96, VIAFLO 384 or other multiwell pipetting systems.
