Benchmark™ Roto-Therm™ Incubated Rotators

• Rotated mixing with temperature control
• Includes tube holders for common tube sizes
• Available with variable speed control and advanced shaking / mixing modes: Mix (Oscillating), Pause, Rock (Plus Model)

The Roto-Therm™ series of incubated rotating mixers provide a wide range of mixing capabilities. Suitable for an array of laboratory applications including resuspension, protein binding, nucleic acid purification, histochemistry, hybridization, etc. The mixers include interchangeable tube holders for accommodating all common tube sizes from 0.5 mL to 50 mL. The motion can be adjusted from vertical (end over end) mixing, to horizontal (rolling or hybridization style) mixing.  

For applications requiring temperature control, the Roto-Therm™ series can be digitally programmed to maintain chamber temperatures of ambient 5°C to 60°C and include an “in-lab” calibration function for ensuring accurate temperature control.

The Roto-Therm™ is also available in a “Plus” configuration, providing the following additional features:

• Variable speed: 5 to 70 rpm
• “Mix” function: Rotating in combination w/ oscillations (increased mixing)
• “Pause” function: Rotating with intermittent “stops” during rotation
• “Rock” function: Back and forth, gentle rocking motion (see-saw)

The Plus model also offers an additional rocking platform (4.5 x 3 in.), as well as a 96 x 0.2 mL tube/strip/plate holder for mixing PCR vessels in the “Mix” (oscillating) mode.

• Convenient cDNA synthesis and PCR in a single tube from 1 pg total RNA
• Formulated for highly specific and sensitive RT-PCR from any RNA templates
• Incorporates thermostable reverse transcriptase and Hot-Start Taq for preparation at room temperature

The PR1MA™ One-Step RT-PCR Kit has been formulated for cDNA synthesis and subsequent PCR in a single tube for end-point analysis. This latest generation RT-PCR Kit consists of an MMLV-derived, thermostable Reverse Transcriptase (45°C to 55°C), an advanced RNase Inhibitor and PR1MA™ Hot Start Taq for ultra-sensitive one-step RT-PCR from as little as 1pg total RNA starting material.

The optimized buffer chemistry allows for efficient reverse transcription and PCR of problematic sequences with significant secondary structure (such as GC-rich targets). The PR1MA One-Step RT-PCR Kit is ideal for determining the presence or absence of RNA templates and quantifying expression through qualitative analysis of RNA transcription levels. The kit also efficiently synthesizes double-stranded cDNA for subsequent gene expression analysis.
