PR1MA™ Mini Digital Incubator

  • Digital temperature control
  • Personal sized, 13 x 14.5″ footprint (20 L)
  • Accepts bottles and flasks up to 2 L
  • Internal outlet, for installation of shaker, rockers, etc.

 

With digital temperature control, the PR1MA™ Digital Refrigerated Incubator provides a convenient “set and walk away” operation, eliminating the need for external thermometers and repetitive “fine-tuning” of an analog control knob. Simply choose the desired temperature and the incubator immediately begins to heat up while accurately monitoring the chamber temperature and conveniently displaying the temperature in real-time on the large LED control panel.

 

Despite a modest footprint of 14.5 x 13″, the incubator features a large internal chamber, capable of storing flasks and bottles up to 2 Liters. In addition, the incubator includes two adjustable shelves and an internal outlet for powering small shakers, rockers, and other instrumentation. A mini nutating rocker (H3D1020) supplied with both flat and dimpled mats is available for the agitation of samples during incubation.

PR1MA™ V2 Vortex Mixer

  • Reversible top platform, cup, or flat-dimpled surface
  • Powerful motor for INSTANT vortexing
  • Continuous or touch operation
  • Q Drive dynamic balancing system
  • Variable speed from 200 to 3200 rpm
  • Wide variety of accessories, for tubes up to 50 mL

The PR1MA V2 Vortex Mixer utilizes a smooth and powerful mixing technology, with the advantage of a uniquely designed reversible rubber head that can be attached to the mixer in two orientations. For the vortexing of single tubes, the cupped surface would generally be preferred. However, for applications requiring a flat/dimpled surface for mixing uniquely shaped vessels (or a handful of multiple test tubes), the head can easily be flipped over and reattached in reverse orientation.

 

The drive system is balanced with Q-Drive technology, providing a smooth vortexing action, while minimizing noise and excessive vibration. This results in quieter, more efficient, and longer lasting operation. With a maximum speed up to 3,200 rpm, the mixer provides an instant vortex of even the largest sample sizes, including full 50 mL tubes.

PR1MA Digital Dry Bath Series

 

  • Digital temperature control
  • Hinged lid
  • External (optional) temperature probe
  • Available with Quick-Flip universal blocks (supports all common tube sizes, PCR strips, and PCR plates)
  • Blocks sold separately

 

The PR1MA Digital Dry Bath Series is a "next generation" product line that introduces several major advantages over traditional dry baths. They are the first digital dry baths to include advanced microprocessor controls, timed or continuous operation, and a removable hinged lid. In addition, an optional external temperature feedback probe can be positioned directly inside a sample tube, providing real-time control and monitoring of actual sample temperature.

 

The PR1MA Digital Dry Bath's transparent lid helps to promote better uniformity and minimize temperature stratification in the block by maintaining a warm air jacket layer. It also helps to reduce energy consumption by minimizing heat loss to the environment. The hinged lid can be flipped open (to the rear), or easily removed (lifted off) to accommodate taller tubes.

 

Both the single and dual block models can be ordered in a configuration that includes our unique Quick-Flip blocks. These universal blocks accept tubes from 0.5 to 2.0 mL and, with just a quick flip to the other side, accommodate 0.2 mL tubes, PCR strips or (in the dual block model only) a PCR plate.

 

Other blocks are available for tubes up to 50 mL.
