Turn your Vendor into a Partner  Coming Soon: Complete and Collaborative Asset Management

After 25 years of experience with all types and sizes of laboratories, one dominant theme has resurfaced with our customers. Laboratory pipettes are numerous, expensive, and time-consuming. They are a bother, and can take significant time to manage. They cost money to purchase and maintain.   In one way or another, customers are lacking the full control they seek over their critical laboratory equipment, and wish their vendor could do more for them under a system of accountability. At TTE, we have a proven track record of empowering our customers to make data driven decisions that secure their process, control their costs, and bring efficiency to their operations; but we’ve always hoped for the tools to improve on our ability to assist our customers.   We have some good news for you! We’ve found a way to match our desire to improve the service to our customers by meeting this challenge. The answer is our new collaborative Pipette Asset Management Platform powered by Qualer. ...

The Value of Training


Most labs spend very little time teaching their employees how to pipette correctly. Its understandable, since using a pipette is perceived to be a basic skill that every qualified lab technician possesses. In our experience at TTE, pipette techniques and understandings vary greatly amongst a wide variety of our customers, and some lab employees don’t understand that accurate pipetting is a skill that impacts their work! Even some of the most demanding laboratories have employees that pipette incorrectly---and some have been doing so for years! In fact, 70% of all pipette error is due to the user. Lab managers know that a trained employee is certainly less likely to damage delicate equipment such as pipettes, and understand the impact of best practices upon their results. Investing in outside expert training is the best way to protect your lab results. It also reduces the amount of corrective work and deviations, which amounts to a huge cost and delay. TTE will partner with you to free you and ...

The Dos and Don’ts of Pipette Storage and Handling


With the delicate nature of pipettes, it’s easy to damage them. This brings unnecessary costs to your lab and can cause lab managers some real frustration. Using the proper storage and handling protocols can extend the life of your equipment. Its simple, but important. Here’s a quick overview of some recognized best practices when it comes to storing, using and taking care of pipettes: Do choose the right tool for the job. Pipettes are available in a wide range of sizes and configurations — do your research and make sure scientists at your facility have access to the tools they need to get the job done right. TTE can train you on which air displacement pipette to choose for which volume, and show you other pipettes that may give you better results, such as positive displacement tools. Don’t overfill a pipette or attempt to use it for anything other than its intended purpose. Its not a stirring rod, hammer, or toy. Make sure the correct accessories are available, and th ...

Five of the Largest Laboratory Costs Associated with Pipettes: How to Control and Reduce Them


Five of the Largest Laboratory Costs Associated with Pipettes: How to Control and Reduce Them

Unseen, Ongoing and Residual--these are words that often describe the excessive and frustrating costs associated with pipettes in the regulated laboratory. In our experience with our customers, here are five of the common sources of these costs that vary in their severity depending upon your applications. We hope we can help guide you to controlling, and perhaps eliminating some of these costs. 1.Pipette Deviations Our customers tell us that pipette deviations cause the most concern. Deviations result from a pipette failure during initial “As Found” calibration, but also occur when pipettes are found to be problematic for one reason or another during a lab process. Deviations are found to be upwards of $15,000 each due to lengthy impact investigations, lost work time, repeated experiments and other factors. A few successful countermeasures may be decreasing a calibration interval to reduce investigation time, pipette training seminars to reinforce Best Practices in order to prevent mistakes or m ...

Preventing Repetitive Strain Injuries in the Lab


Repetitive strain injuries are an occupational hazard in any lab or research center. An estimated 90 percent of researchers report pain after pipetting for an hour or longer, leaving them at risk of developing chronic injuries or nerve damage.  TTE Laboratories is happy to assist scientists who call in to our office to ask about more ergonomic, lighter pipettes, but often times, they call after the damage has already been done. Pipetting is an important daily task for most researchers. So, what can you do to reduce the chances of an injury? Read on to learn more. Use the Right Tools It only makes sense that the pipette itself plays a role in preventing repetitive strain injuries in the lab. If you’re considering upgrading your current pipette to a newer, ergonomically designed model, you should consider: Operating pressure: The more force it takes to operate a pipette, the more strain you are putting on your wrist and hand, particularly your thumb. Trading an older manual pipette in f ...

Proper Pipette Cleaning and Decontamination Tips


Like any sensitive equipment, pipettes require regular maintenance to keep working their best. Leading laboratories throughout the country know to trust TTE Labs for all of their calibration, preventative maintenance, and pipette repair needs, but what can you do on your own to prevent premature wear and extend the life of these delicate instruments? Read on to learn more. Exterior Pipette Cleaning You should decontaminate your pipettes before you send them for calibration. Fortunately, the process is easy and takes only a few minutes. Here’s how to do it: Gather the right tools. In addition to the pipette itself, you’ll need a box of KIMWIPES or a similar task wipe and a cleaning solution. We recommend a 70-percent ethanol or 10-percent bleach solution. Clear a space. To avoid accidental damage to your pipettes, clear your work area of clutter. Clean the pipette. Gently wipe down the outside of the pipette with a dabbed KIMWIPE. Do not disassemble the pipette or submerge it in ...

On-Site Vs. Off-Site Calibration


Pipettes play important roles in laboratories throughout the world. In order to replicate test results and arrive at accurate diagnoses and discoveries, researchers create and observe very specific biological processes. These processes often depend on the repeatability of exact ratios and precise measurements. Pipettes must deliver both as they contain, transfer, and measure fluids in a laboratory setting. Of course, pipettes and the mechanical parts within them, such as plungers and pistons, will undergo slight changes over time. Cross contamination, temperature or humidity changes, human error, and everyday wear and tear will compromise a pipette's accuracy and function. That's why it's so important to clean your instruments thoroughly and seek accurate and effective calibration services that operate according to the science of liquid measurement. Your calibration service must follow strict regulations and methodology standards set by ISO, the International Organization for Standardization. ...

How Not To Choose a Pipette Calibration Service Provider


How Not To Choose a Pipette Calibration Service Provider

As is the case with many decisions, when the complexity of the choice is not well understood, people make their choices based on convenience and price. Though both of these factors are important when choosing a calibration service, a more important factor is how effective the service provider is.
