Ease of use: One step sample concentration in a single tube, for minimal sample handling and reduced sample loss, as well as pH compatibility over a broad range – pH 1 to 9. Sample protection: Patented Vivaspin deadstop technology ensures samples cannot be concentrated to dryness and enables direct concentrate recovery. High flow rates: And minimal membrane blockage through the vertical polyethersulfone (PES) membrane design. Minimal protein adsorption: Thanks to the Vivaspin™ polycarbonate tube design. Wide selection: Vivaspin sample concentrators are suitable for sample volumes ranging from 100 μL to 20 mL, with a range of molecular weight cutoff (MWCO) values from Mr 3000 to 100 000. IPGbox is designed for simultaneous rehydration of up to 12 Immobiline DryStrip gels IPGbox is used together with the IPGbox Kit to rehydrate 7 to 24 cm Immobiline DryStrip gels. The IPGbox Kit contains 1NA disposable Reswell Trays and one disposable IPGbox Insert. The IPGbox comes with the complete set of accessories to rehydrate 1NA full rounds of 12 IPG strips each. IPGbox and IPGbox Kit are tools for enhancing the reswelling of GE Healthcare’s precast Immobiline DryStrip Gels (IPG strips). The IPGbox (Fig 1) is an accessory to the Multiphor and IPGphor isoelectric focusing systems. It provides a convenient method for rehydrating up to twelve precast IPG strips (7 to 24 cm) at a time. Individual slots in the Reswell Trays allow rehydration of individual IPG strips in a minimum volume of solution. The IPGbox includes a lid that protects the strips from dust and other contaminants during the rehydration period, which ranges from 1NA h to overnight.
