Cleaning Pipettes Can Protect Your Sample

No matter whether you use manual or electronic pipettes, both can get contaminated and dirty from all the different liquids and solutions they are exposed to.

There Is No Need to Lubricate Pipettes After Each Cleaning or Autoclaving

It is not obvious when a pipette needs lubrication because the lubricant is inside the pipette and cannot be seen unless the device is disassembled.

Is Calibration of Pipettes After Autoclaving Mandatory?

Calibration of pipettes is a necessary procedure to guarantee accuracy and precision for all pipetting activities. But it is also time-consuming and expensive.

How to Clean a Bottletop Dispenser

Bottletop dispensers are used for various, sometimes very aggressive chemicals. Nobody wants residues of a previous chemical in a new analysis.

Electronic Pipetting –Time to Rise to The Challenge

Do you pipette difficult liquids like ethanol, glycerol or detergents with air-cushion pipettes? Then you should double-check your pipetting technique, if you want to get the best out of your pipetting.

How to Stop Dripping When Pipetting Volatile Liquids

Who isn’t aware of acetone, ethanol & co. starting to drip out of the pipette tip directly after aspiration? Probably, every one of us has experienced this.

Viscous Liquids Need Special Pipetting Techniques

Do you cut off the pipette tip when pipetting glycerol? I did during my PhD, but I had to learn that this increases inaccuracy and imprecision of my pipetting

Application Diversity of Electronic Dispensers

Many researchers work with manual dispensers, e.g., for filling plates or preparing aliquots. Electronic dispensers are less commonly used, but can help to make your work much faster and easier.

Benefits of Dispensers in Cell Culture

Benefits of positive displacement dispensers in cell culture are manifold. A major advantage is complete aerosol prevention as the sample is hermetically sealed in the tip.

Pipetting small volumes - How to tame the 384-well beast?

Do the tips fit? Will I manage to concentrate sufficiently on 384 tiny wells? Will I be able to fill the plate flawlessly? Do these concerns look familiar to you?

Strong Acids, HPLC and Sterile Medium with Bottle-top Dispensers

Accessories can improve the use of the dispenser and broaden the application range. So, from only using bottle-top dispenser for buffer medium...

How Drying Tubes Protect Your Solutions

Fuming acids are characterized by gas rising off the surface. These acids are made of the maximum concentration of gas dissolved in water, such as 37 % hydrochloric acid and 65 % nitric acid.

When You Think about Pipetting Liquids, Think Twice

Starting an experiment means asking many questions. Which material is needed? Which samples are used? Which conditions are necessary, e.g., growth?

Ergonomics: Why Pipetting Ergonomics is a Key Issue

Whether on board the International Space Station, on a research vessel, in a high-security laboratory, or at other non-automated laboratory workplaces, one thing applies to them all.

Why Your Adjustable Tip Spacing Pipettes Should be Tubeless

We'll show you why and how a tubeless system in your pipettes supports user-safety and maximum efficiency, as well as precision and accuracy.

A Bodyguard for Healthy Working Conditions: The Electronic Pipette

Neck and back problems, pain in the hand and fatigue. That's the other side of lab life. Excessive effort, high operating forces and repeated physical strain can cause health problems in the long run.

How to Reduce the Risk of RSI in 384-well Applications

With the advent of the high-throughput screening approach, the need for a microplate with a larger number of wells appeared and was quickly implemented as a consumable for plate assays.

Ergonomic pipetting of a 384-well plate – How to get the gain without the pain

Higher effort, more concentration, more mistakes, irregularly sitting or dropping off tips. Switching from 96 wells to a 384-well plate doesn't feel like a piece of cake.

Even the Smallest Things Have an Impact on Ergonomics

Have you ever wondered why the control button of your manual pipette is as long as it is?

Ergonomics Is Composed of Body, Mind and the Surrounding

You usually do not notice the ergonomic features of a pipette – if you did, they would be a disturbing factor and thus not ergonomic

Increase Your Creativity by Stretching

Stretching is one of the most natural movements utilized by almost every creature on the planet. Cats and dogs are natural experts in stretching and you would not see one of these animals rising from a nap without stretching.

Proper Pipetting Posture Prevents Muscle Strain During Work

Everyday work in a laboratory puts high demands on our bodies. Air-conditioned rooms, heavy equipment, and long series of repetitive movements strain different muscle groups.
