Electronic Pipettes

  • How do I maintain the accuracy of BluePette's last dispense in Multiple Dispense (MD) mode?

To provide high accuracy to your pipetting, please select Reverse Pipetting in System Mode (SYS) before performing Multiple Dispensing (MD). 

  • How often should I calibrate BluePette?

BluePette is equipped with an auto-calibration feature, which is performed every time it is turned on. We recommend you to send BluePette back to our authorized distributors for calibration every 6 months, or after 100,000 pipetting cycles. 

  • When should I change the batteries of BluePette?

BluePette will emit a beeping sound when the battery level is low. Please stop your pipetting as soon as possible and recharge BluePette to avoid any inaccuracy that might be caused by insufficient battery levels. 

  • After the battery is inserted into the battery compartment and the battery cover is closed, the LCD display remains blank. What should I do?

The LCD display should turn on automatically when users insert the battery into the battery compartment and close the cover. However, the battery is sometimes shaken during insertion, making the battery's metallic contacts touch BluePette's battery contacts twice. In this situation, the LCD display will remain blank. Please press the "RESET" button or reinsert the battery to activate the LCD display. 

  • What's the benefit of the Blow-out function?

To prevent droplet retention on the tip's orifice, we highly recommend selecting the Blow-out setting in System (SYS) mode for all your pipetting. The Blow-out setting will purge an additional 10 μl of air in addition to your selected pipetting volume. 

  • How can I autoclave the lower part?

Please refer to the BluePette Operation Manual to disassemble the lower part. The whole lower part can be autoclaved as one piece. Please wait 3-4 hours for it to air dry before reassembly and calibration. Since there is no spring inside BluePette, autoclaving will not affect the accuracy and precision of BluePette. 

  • Can I use regular grease to lubricate BluePette?

We recommend using the specialized lubricant sold by our authorized distributors. The lubricant used in BluePette is an airtight, high-temperature-resistant, chemical-resistant material. It can undergo autoclaving without losing its accuracy. 

  • Why is BluePette more accurate and precise?

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 into 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 BluePette's step motor, the BluePette not only performs accurate and precise dispensing, but also can monitor the movement of the step motor. 

  • How is BluePette ergonomically designed?

Some ergonomic designs implemented in the BluePette are listed below:

Handler

BluePette's handler design refers to the human palm size database.

Balance

The weight of the lower-part and battery compartment, which are located on both sides of the handler, is equal. This design makes BluePette well-balanced, especially for the 8-channel BluePette.

Buttons

Use your index finger to press the "START" button and your thumb to press the tip ejector. This design saves force and is easy to operate.

LCD Display

This faces the user's eyes. Users can easily see which mode and action is in operation during pipetting.

Keypad

Made of soft rubber.

Quick Setup

Using the "START" button to substitute for the "Increase Volume" button speeds up the setting of function modes.

  • How many pipetting cycles can be performed by a fully-charged BluePette battery?

About 2,000 cycles. 

  • What's the life span of the lithium battery?

Users can recharge the battery for about 500 times. 

  • What safety certifications does BluePette have?

BluePette is CE- and UL-certified, which guarantees the stability and safety of products.

  • How does BluePette comply with GLP?

For Good Laboratory Practice (GLP) labs, all equipment operations should be traceable. BluePette automatically records pipetting cycles. This function is designed for GLP labs and service engineers. Since this function is not frequently used by regular users, it's stored in Service Mode. To access this data, please contact our authorized distributors. 

  • What kind of quality assurance tests are done with BluePette?

Some of the quality assurance tests done with BluePette are listed below.

  • Step Motor life test
  • O-ring life test
  • Buttons life test
  • Tip Ejector life test
  • Tip Fitting life test
  • Temperature Cycling test
  • Storage Temperature test
  • Vibration test
  • Drop test
  • Autoclave test
  • Lower Part Connection test
  • What kind of plastic materials are used in the housing of BluePette?

The upper part of BluePette is made of ABS. The lower part is made of PP, except for the tip fitting, which is made of PVDF. Both PP and PVDF plastics are high-temperature-resistant, chemical-resistant materials. The piston is made of stainless steel.

  • What's the biggest operational difference between manual pipettes and BluePette electronic pipettes?

To achieve good results, manual pipetting requires experience, especially for small volumes. With BluePette, users with or without experience can achieve consistently good results.
