Rugged Mixers for Expanded Laboratory Efficiency

Engage in complete speed control and precise mixing with variable speed mixers such as the R4045 RotoBot Rotating Mixer from Benchmark Scientific. Change from vigorous to gentle mixing as needed for routine mixing tasks, QA analysis, production process, research and development, cell culture, and microbiology purposes with the Benchmark Scientific R4045 tube rotator that disintegrates samples with speed ranging from 1 RPM to 65 RPM. Still in the look out for other options? You can compare this Benchmark Scientific model with the R4040 RotoBot Mini Rotator from Benchmark Scientific having the same speed type and maximum RPM also from the same series and brand.

Simplified and Top Level Lab Mixing No Matter What Application

If you need to work on beakers, conical tubes, and differently sized vessels at once and have these turned end over end, then your lab mixing workhorse should be a tube rotator. Whether for aerating cultures or making sure biosamples are suspended , tube rotators like the digital R4045 RotoBot Rotating Mixer from Benchmark Scientific provides ideal sample mixing for histochemistry, biochemistry, molecular biology, and clinical applications. The Benchmark Scientific R4045 can also be used to manage temperatures ranging from 2°C - 70°C, securing an array of applications calling for accurate and precise temperature control

The RotoBot™ Rotating Mixers feature advanced programming options that far surpass that of the traditional laboratory rotator. With digital speed control and more than 10 operating modes, the RotoBot can be selected to perform a wide variety of rotating, mixing and vibrating actions. In addition, these actions can be combined in succession using the C1 and C2 “Custom Modes” , providing the user with a nearly infinite level of programming.

The RotoBot and RotoBot Mini each inlcude an assortment of vertical tube holders. The Mini model is supplied with holders for 12 x 1.5ml tubes, 2 x 15ml & 2 x 50ml tubes; the standard model, 30 x 1.5/2.0ml, 8 x 15ml & 2 x 50ml tubes. For higher capacity applications, more of these holders can be purchased as accessories. In addition, horizontal holders are available for applications such as Western blotting and hybridization. The unique, sliding attachment allows for quick and easy changing of tube holders.

For rocking applications, a platform with a non-slip rubber mat is available. Once attached, simply select the “PP” mode to turn the rotator into a platform rocker.
