Labnet Mini Microcentrifuge

• Quick release rotor system - no tools needed to exchange rotors
• Electronic braking - Allows for more rapid deceleration, less waiting
• Dual lid switch
• Compact, rugged design

Simple and convenient to operate, the new Labnet mini microcentrifuges feature greater capacity (8-place MCT and 4-place PCR strip rotors), a quick-release rotor system and electronic brake.Once samples are loaded and the lid is closed, the rotor rapidly accelerates to 6,000 rpm, making it an ideal centrifuge for bringing small droplets to the bottom of tubes for micro-filtrations or basic separations.

SmartDrop™ Nano Spectrophotometers

Microvolume Analysis of DNA, RNA and Proteins

JULABO Refrigerated & Heating Circulators for heating and cooling are suitable for external temperature tasks and for temperature applications directly in the bath. A model from three different series' with different capacities can be selected. Powerful circulating pump systems and high heating and cooling capacities guarantee short heat-up and cool-down times. The inevitable dust accumulation that occurs in refrigeration systems is solved by means of an easily removed venting grill, which allows for easy cleaning. Depending on the model, the units are equipped with handles or castors for an easy transportation. All models have a drain tap on the front allowing the fluid to be drained easily. The compact assembly of each unit enables a space to be saved in the laboratory.

• Bright LED temperature display, resolution 0.1 °C
• Keypad for setpoint, switches automatically to the actual value
• PID1 temperature control
