Pipette Tips - 5 Things You Need to Know


For those of us who calibrate on a daily basis, the repeated routine of pipetting may have become almost second nature.  In fact, a metrology-centric calibration program should provide the standardized expertise necessary for proper performance assessment and maintenance.  However, periodically brushing up on the fundamentals of practice and procedure can refresh your skills, correct errors, and remind you that even the smallest mistakes can lead to major ramifications in the lab space. Understanding your process and having mastery of your chemistry lab supplies, or biology techniques, will play a huge role in your success or failure. So let’s go back to the basics to ensure the highest quality of service and measurement at every turn with these 5 things you need to know about pipette tips:

Calibration Management Best Practices: 5 Tips for Keeping One Step Ahead of the FDA

Every year, commercial and research laboratories await the Food and Drug Administration’s (FDA) annual audit of their establishment’s compliance to the strict requirement guidelines. The FDA regulations for laboratory environments are based on the ISO 17025 standard, which focuses on the level of competency and consistency in lab methodology. For companies conducting laboratory research, the ISO 17025 standard applies to pipettes, dispensers, diluters, and burets.

The Evolution of Pipette Calibration Services

Part Two of a two part series

In part 1 of this blog, I described the landscape of the pipette market, and the developing pipette service market, from the 1960s through the 1990s. In the 30+ years of biology, clinical and metrology lab experience I have accumulated, I recognized two significant events during the past 14 years that have significantly impacted and shaped the pipette calibration service market today. In Part 2, I will describe these events and what impacts they had.

The Early Years
The mechanical pipette (micropipette) was invented in the early 1960s and has historically become one of the most significant laboratory tools over the last 50 years. It was further developed into an adjustable micropipette in 1972. At this time, there were limited service options for pipette users, as pipette manufacturers initially guided customers toward replacement pipettes. While clinical laboratories were dominated by the MLA brand; Eppendorf, Gilson Pipetman® and Finnpipette® dominated the R&D laboratories, and new brands ensued. The pipette calibration market had yet to develop, as pipettes were mostly sent back to their manufacturers for repairs, which included lengthy turnarounds. Scientists then were at a disadvantage, as pipetting accuracy and repeatability remained largely unchecked, and laboratory procedure had to accommodate wide tolerances. 

How to Choose a Pipette Calibration Service Provider

Contracting with a service provider to properly and correctly service your laboratory pipettes is an important step in the security of your laboratory liquid handling system.  Unfortunately, there are many different providers to choose from with widely varying procedures and competencies.  Even among accredited providers, quality can vary from poor to excellent, so it pays to make this decision carefully.  Be careful!  Choosing the wrong provider can cause added expense and problems. 

Here are a few things to consider when choosing who will be cleaning and calibrating your pipettes:
