Incubating orbital shakers with and without refrigeration, R denotes refrigeration. Bench top E24 or E24R can accommodate test tubes or flasks up to 2,8 litres in a tightly sealed growth chamber; they feature a clear acrylic lid for excellent visibility of samples. For larger capacity applications, the floor standing E25 and E25R models have a large viewing window in the top-opening lid and these models accept flasks up to six litres.

• Uniform temperature control by self-correcting microprocessor feedback control and tightly constructed chamber. High-velocity fans ensure rapid thermal recovery
• Integral timer, 0,1 to 99,9 h, shows elapsed time or counts down, automatic switch-off and audible alarm when program is complete
• Large LED display shows speed, run time, self-diagnostic indicators and temperature
• Unicentric drive with brushless motor ensures quiet, reliable, vibration-free operation with high loads and at high speed
• Safety features include automatic cut-out when lid is opened to protect operator and fail-safe thermostat that turns off heat if high temperature limit is exceeded to protect cultures

Microprocessor controls allow temperature and speed to be calibrated via keypad. Microprocessor controller recalls last set points, even when power is interrupted, and restarts shaker when power resumes. Self-correcting microprocessor system continuously monitors and compensates for changes in workload, voltage and temperature and will maintain set point. Audible and visual alarms alert user if set point limit is exceeded, audible alarm can be muted. E25 models have adjustable feet to absorb vibration and help stabilise the load.
