When you need 20ul Filter Tips to use a liquid sample, you may have a couple of different options. The first consideration is whether you want precision and/or accuracy. There is some variation in tip shapes, which can be a quality control problem, and the build quality can vary. To avoid variability, purchase good quality tips. There are some other factors to consider when selecting a pipette tip.

Choosing a Pipette

It may seem like a simple process, but choosing a pipette tip can be a daunting task. Fortunately, there are several factors to consider when choosing the right one. A good tip should fit the pipette perfectly and remain sealed throughout the pipetting process. The tip should also eject without causing any problems and should be pure. In addition, the tip should be backed by a manufacturer’s guarantee of quality.

A good pipette tip should be accurate for the volume of liquid you intend to measure. It should have a tight seal, as a loose seal could let air out of the pipette barrel and result in inaccurate liquid measurements. While pipette manufacturers sell tips specifically for their pipettes, it’s best to purchase universal tips if you’re unsure. Choosing the right tip will make your pipetting experience a more enjoyable one.

In addition to the size and shape of pipettes, there are several other factors to consider. The tip’s material, fit, and quality all contribute to their performance. A high-quality tip will help to ensure reproducible results, save time, and reduce contamination risks. Quality pipettes aren’t cheap, and an affordable tip will improve your productivity and decrease your costs. However, the quality of your pipette tip is just as important. If you don’t use the proper tip, your pipette won’t be as accurate, and the tips’ fit will affect the reproducibility of your experiment.

Identify a Poor-Quality tip by its Irregular Spacing

When choosing a pipette tip, consider the needs of your samples. You can easily identify a poor-quality tip by its irregular spacing. For better results, insert the tip vertically, press the tip gently, and turn it to tighten it. Alternatively, choose a multi-channel pipette with several tips that are in line and in the same orientation. When choosing a multi-channel pipette, make sure that all the tips are evenly spaced and shakable.

Choose the type of precision and accuracy you need. Depending on the tip, different pipette models offer different degrees of accuracy and precision. The shape of the tips varies, depending on the build of the pipette. Cheaper tips are less precise and will result in poor results, while high-quality universal tips give accurate results. To prevent problems with precision, ensure that you buy universal tips made by top-tier manufacturers.

Ensure that the pipette tip you choose is made of virgin polypropylene. Non-virgin tips are made with metal and plastic additives, which can contaminate your sample. Polyethylene-based tips are free of cellulose, and should contain no additives or cellulose. Pipette tips are manufactured in an injection molding machine. The quality of polypropylene and mold design determine the shape and quality of the tip.

Choosing a Pipette with FlexFit Technology

When choosing a pipette tip, accuracy and precision are important factors. However, the wrong tip can compromise accuracy. It can also result in the wastage of valuable samples and reagents. Therefore, it is crucial to choose a tip that offers a great seal. The following tips will help you choose the right tip for your needs:

X-Resin-treated tips are also available in the market. This technology ensures low retention and insertion forces for ergonomic pipette tips. As a result, these tips reduce the risk of repetitive stress injury. This technology also allows pipetters to save time and money by eliminating the need for manual measurements. FlexFit tips have many other advantages, and we will discuss some of them below.

Last Words:

Universal tips are the best choice for most micropipettes. Their diameter is generally similar to the pipette barrel diameter, but the tip should fit snugly without any force. Most brands of pipette tips have compatibility charts for the most common pipette models. You can check out the compatibility chart to find the right tip for your application. If you have to use the tip on a non-universal pipette, it is best to choose a tip with FlexFit technology.
