Description

Clear, scratch-resistant lid allows unobstructed sample viewing without disturbing chamber temperature.

• Chamber holds four 1L flasks
• Choose from two temperature ranges: incubated (5°C above ambient to 80°C) or with a cooling coil option that requires a chiller (5°C below ambient to 80°C)
• Monitor and control chamber temperature range with ±0.1°C accuracy at 37°C
• Triple eccentric drive handles heavy loads, uniform agitation and continuous 24-hour operation, even at high speeds
• Overtemperature safety feature with independent thermostat provides additional backup by controlling heat if main temperature controller fails
• Interlock stops platform when lid is opened

Analog Models

• Speed is controlled by a rotary dial, monitored accurately by a traditional tachometer
• Easy-to-read LED digital temperature display
• Speed: 40-400rpm
• Integrated tachometer monitors and displays speed in rpm to guarantee an accurate setting
• Timed: 1 to 60 min. or continuous

Digital Models

• Three individual LED displays: speed, time and temperature
• Variable speed control from 15 to 500rpm
• Continuous and timed operation from 0.1 hour up to 999 hours or 0.1 to 999 min.
• Shaker shutdown and audible/visual alarms signal temperature deviations or if unit operates ±10% of set speed, preventing shaker from walking
• Soft-start feature eliminates sudden starts and stops, splashing of vessel contents or wetting of flask closure
• Set point retention retains parameters during power failure and restarts unit automatically after power is restored
• Solid-state DC brushless motor is maintenance-free

Operating Chiller

• Provides a refrigerated atmosphere
• For plasmid purification and protein expression in bacteria for use with MaxQ 4450 with cooling coil option
• Achieve temperature ranges from 20° to 30°C

• Cell culture
• Solubility studies
• Extraction procedures
• Plasmid purification
• General mixing
• Bacterial suspensions
• Staining and destaining
• Washing procedures
• Hybridizations
• Protein expression in bacteria
