To ensure high accuracy pipetting, please select Reverse Pipetting in System Mode (SYS) before performing Multiple Dispensing (MD).
BluePette has an auto-calibration feature, which is executed every time it is turned on. We recommend that BluePette be sent back to our authorized distributors for calibration every 6 months, or after 100,000 pipetting cycles
To prevent droplet retention on the orifice tip, we recommend selecting the Blow-out setting in System (SYS) mode for all your pipetting. In the Blow-out setting an additional 10 μl of air is purged in addition to your selected pipetting volume.
Please refer to the BluePette Operation Manual to disassemble the lower part which can be auto¬claved in one piece. Please wait 3-4 hours for it to air dry before reassembly and calibration. There is no spring inside BluePette, so autoclaving will not affect its accuracy and precision.
The core engine of BluePette is a patented, high-precision step motor which enables BluePette to dispense with high accuracy and precision.
Small step motors which control the rotation in very small angles are widely used in many high precision applications, such as digital cameras, scanners, and laser printers.
With the patented auto-monitoring feature of the step motor, the BluePette not only performs accurate and precise dispensing, but can also monitor the mechanical operations of the device.
Some ergonomic designs implemented in the BluePette are listed below:
￭ Handle: The BluePette handle was designed with reference to the human palm size database.
￭ Balance: The weight of the lower-part and battery compartment is equally distributed on both sides of the handle. This design makes BluePette well-balanced, especially in the 8-channel model.
￭ Buttons: Use your index finger to press the "START" button and your thumb to press the tip ejector. This design is less tiring and makes operation easy.
￭ LCD Display: This faces the user so that it is easy to see which mode and action is in operation during pipetting.
￭ Keypad: Made of soft rubber.
￭ Quick Setup: Use the "START" button to substitute for the "Increase Volume" button, this speeds setup of the function modes.
About 2,000 cycles.
The battery can be recharged about 500 times.
