VWR Scientific 12620-910 Digital Incubating Rocker 1-50rpm 10x7.5in Tray 120V

VWR Scientific 12620-910 Digital Incubating Rocker 1-50rpm 10x7.5in Tray 120V

The VWR Scientific 12620-910 is a benchtop digital incubating rocker designed for temperature-controlled rocking and mixing of samples in a laboratory setting. It combines a heated platform with a programmable rocking motion, making it suitable for cell culture work, blotting procedures, hybridization assays, and general sample agitation that requires a stable, elevated temperature. The unit features a clear acrylic humidity and draft shield, a digital LED control panel, and independent adjustment of temperature, speed, and timer.

Applications

Incubating rockers like the VWR 12620-910 are standard equipment in molecular biology, cell biology, and biochemistry labs. The rocking motion keeps samples in gentle, continuous movement — important for preventing cell settling, promoting even hybridization of probes to membranes, or ensuring uniform antibody coverage during Western blotting and Southern/Northern blotting protocols. The heated chamber extends this capability to temperature-sensitive applications: hybridization steps typically run at 42–65°C, while mammalian cell culture work often requires a stable 37°C environment. These instruments are also used for gentle mixing of blood samples, tissue culture flasks, and staining/destaining gels. The programmable timer allows unattended operation with automatic shutoff, which is useful for overnight protocols. The VWR 12620-910 was manufactured by Henry Troemner LLC, a long-established maker of precision laboratory balances and mixing equipment, and dates from the late 1990s era of digitally-controlled benchtop lab instruments.
