Accuracy Matters

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:
 

8 Tips to Improve Your Pipetting Technique

 

In a recent blog post, TTE highlights the quality, convenience, and standard compliance offered by metrology-based pipette calibration service providers. Here at TTE, our lab technicians take conscious steps to utilize the best procedural practices, making sure we are compliant with every aspect of FDA regulations and ISO 17025 and ISO 8655 standards. In order to obtain the most accurate results, we practice a number of tried and true pipetting techniques, lowering our risk of error.

The following is a list of 8 helpful tips for your lab to consider, based on our own successes. These techniques are intended to further improve your pipetting practices and ensure the most accurate test results.  Consider these best practices the next time you pipette:

1. Use consistent force when installing the pipette tip: When installing your pipette tip, it’s important that you apply the same, consistent force to ensure a proper fit each time. Do not jam the tip in place; this can damage your pipette tip and negatively affect your results.

 

The Remarkable Cost of Pipette Errors

Pipette -  The Primary Laboratory Measurement Tool

Laboratory scientists use piston-operated volumetric apparatus, otherwise commonly referred to as pipettes, every day, while developing drugs and therapies, or to provide critical diagnostic test results. The objective is clear: to improve the lives of many through good science. Pipettes are the laboratory ‘tool’ that provides scientists with an ability to measure very small volumes of liquid with a very high degree of accuracy and precision.  When pipetting performance is high, the science can advance effectively. But when pipetting performance is low, test results are affected, often leading to costly rework.

Guide to Ergonomics

Typical force and repetition rates in manual pipetting rates in manual pipetting add up to 5,000-10,000 lbs/day, enough to push over an elephant

Pipetting Accuracy: Like Holding a Concert in Your Hand

What Does the Symphony Have to Do with Pipetting? 

While one might not naturally associate laboratory scientists with symphony conductors, they, like conductors, do rely on a similar arrangement of finely tuned and integrated instruments, skills and techniques to achieve high pipetting performance and reliable test results.

Why Calibrate Your Pipettes

Pipettes are the primary tools that laboratory scientists use each day, perhaps as a hammer is to a roofer. They provide accurate measurements of very small volumes of liquids in the user’s quest to obtain correct test results. But pipettes are mechanical devices that require regular calibration service to maintain their accuracy and precision.  The similarities are not unlike the maintenance of your car. Without regular service and repair, your car can break down, leave you stranded and result in high repair costs. Pipettes are no different. Let’s explore this further, directing our focus to the measurement science and relevant standards.

The Importance of Proper Pipette Repair

TTE Replacement PartsProper pipette repair service must include established, model-specific components, maintenance and repair processes in order to ensure valid compliance to tolerances, as well as maintaining measurement performance between service intervals.

Pipette Service Providers – Are They All the Same?

Pipette Calibration - The Correct WayMaintaining the performance of your piston pipettes and related measurement equipment is a key ingredient in the quality of your science. However, pipette services vary greatly from one to the next, leading to confusion about which service provider to select.

Pipette Calibration Services: “Oh, You Still Do That?”

In the wake of the recession, many academic, biotech, and pharmaceutical labs have been forced to take costs into consideration in order to remain nimble in today’s economy.  For these companies, which rely on ISO-accredited pipette calibration & metrology repair services to conduct research in their laboratories, traveling pipette service providers may
