The BenchMixer(r) XL is a heavy duty vortex mixer designed to facilitate hands-free mixing in tubes, flasks, vials or cylinders. It is ideal for the QuEChERS pesticide analysis method and is instantly adaptable to an exceptionally broad range of vessels, racks and applications (horizontal or vertical). The precisely balanced drive system includes an oversized motor that delivers accurate, reproducible speeds up to 2500rpm with rattle-free operation and minimal vibration. The programmable pulsing function allows for time specific interval mixing, increasing agitation.
The 7x12 inch platform accommodates a wide variety of standard, pre-drilled tube racks. Additionally, BenchMixer XL can easily be adapted to almost any type of vessel commonly found in the laboratory (contact us for details).
Using BenchMixer XL is easy; after loading the sample rack and tightening the locking knobs, select the desired speed and run time on the large digital control panel. Then, simply press Start and the BenchMixer XL will perform unattended mixing for up to 100 hours.
BenchMixer XL's large capacity and adaptability make it an ideal choice for the medium to high throughput laboratory.
The BenchMixer XLQ
Benchmark’s BenchMixer XLQ Multitube Vortexer been designed for use in QuEChERS and other sample prep methods. Supplied with racks for 50ml tubes held horizontally and 15ml and 1.5/2.0ml tubes held vertically, it takes the place of traditional manual shaking in these applications.
Multiple samples can be processed simultaneously in the BenchMixer XLQ’s large capacity racks, saving time and preventing operator fatigue. The vigorous, consistent shaking ensures all samples are exposed to identical conditions within the same batch of samples, as well as between batches.
The BenchMixer XLQ creates a true vortex in vertical sample racks by holding the top of the tube stationary while the bottom rotates in a 3.6mm orbit. Time and speed are precisely controlled by the digital microprocessor. A pulse mode allows for more vigorous mixing. Quiet operation, minimal vibration and a long service life are guaranteed by the precisely balanced drive system and powerful motor.
Using the BenchMixer XLQ is simple. To load the sample racks, loosen the knobs on the stationary steel rods and raise the top sample plate. One rod is shorter than the other, allowing the plate to be lifted up and swiveled to one side. After samples are loaded, lower the plate into place and tighten the knobs. Select the desired speed and run time on the digital control panel and press start. The BenchMixer XLQ can perform unattended mixing for as little as 1 minute or up to 100 hours.
While the BenchMixer XLQ is configured primarily for QuEChERS protocols, additional racks are available to accommodate nearly any type of vessel commonly found in the laboratory (ask for details). Built for heavy-duty use, the instrument carries a 2 year warranty.
