GPP Risk Check

GPP - Good Pipetting Practice
You can improve your data quality with Good Pipetting Practice – Rainin's comprehensive, systematic approach to maximizing pipetting accuracy and repeatability. GPP is grounded in Rainin's more than 40 years of expertise working side-by-side with researchers to achieve the highest levels of accuracy and precision across all applications. Apply the principles of GPP in your lab, and everyone on your team will:

  • Understand the array of liquid handling instruments and options available
  • Know how to optimize their workflow for each of the liquid handling steps involved
  • Gain the range of pipetting skills necessary to produce reliable data
  • Appreciate how ergonomics can influence data production and their own well being
  • Recognize the risk associated with out-of-calibration pipettes and the role of routine checks vs. professional service.

1 Evaluation
Determine your needs
Understanding your options is the first step toward achieving more reproducible results. A clear idea of your desired workflow and the level of accuracy and precision required will speed your evaluation of applicable tools and technologies.

2 Selection
Get the right tools
The characteristics of liquids you're measuring can profoundly affect pipette performance. Your time and materials are expensive, so making sure that pipettes, tips and related tools are optimized for your application will save money and increase productivity.

3 Installation & Training
Assure proper use
An optimized pipetting system is only as good as the people who use it. Good technique and knowing which techniques to use for various liquids has a profound effect on precision, accuracy and repeatability of your results.

4 Calibration
Manage your risk
Precision pipettes should come with an ISO calibration certificate when purchased, then should be scheduled for regular calibration, based on use. Try our online Risk Check to better understand your risks and how to mitigate them.

5 Routine Operation
Verification and service
Well maintained pipettes, periodic verification and a system for assuring that every pipette in your lab receives regular service is essential to maintaining a high performance environment.
