Benchmark Scientific Incu-Shaker™ 20L

Category Incubated Benchtop Shakers
Manufacturer Benchmark Scientific

The new Benchmark Incu-Shaker™ 20L and 20LR introduce a high-throughput, space saving shaking incubator system to the Incu-Shaker family. Now with stacking capability of up to 2 units, the Incu-Shaker™ 20 series are highly space-efficient without compromising on reliability or temperature performance. Thoroughly tested for years of reliable performance, the same proven brushless induction motor drive is featured as in other Incu-Shaker instruments. The high grade stainless-steel internal chambers provide temperature accuracy within ±0.1°C, and industry-leading uniformity within the chamber of ±0.5°C. The Incu-Shaker™ 20L features temperature control from 5°C above ambient temperatures up to 60°C. The 20LR features a built-in powerful compressor, allowing for cooling down to 4°C, even while the shaker is in use, up to 60°C.
The increased chamber size now allows for up to 4 5-Liter Erlenmeyer flasks to be in use at once. Usable space is maximized by providing adjustable shelving above the shaker platforms, which can be used for incubation of Petri dishes, cell culture plates, or other smaller vessels. Even when two stacked units are working, the noise and vibration levels are significantly minimized by the advanced, computer-designed motor isolation system.
The Incu-Shaker™ 20 series feature a non-slip rubber mat platform, and can be outfitted with Benchmark’s MAGic Clamp™ universal magnetic platform. Magnetic flask attachment accessories can then be used, allowing for easy, toolless addition and removal of flasks from the shaker. Flask clamps of most sizes, tube racks, and other magnetic vessel holders are available and usable with the Incu-Shaker™ 20L and 20LR. The Incu-Shaker 20L and 20LR are now available for efficient, repeatable growth culture and other applications.
