Advantages of Buying Pre-Sterile Pipette Tips

Posted  by anna on April 15, 2022

There are many benefits of using sterile pipette tips in experiments. They reduce cross contamination and improve results. However, not all scientific research requires pipette tips to be sterile. Therefore, purchasing pre-sterile pipette tips is important to avoid contamination of samples and reagents and to produce better results. There are many different kinds of pipette tips available. Here are some of the advantages.

Sterile pipette tips are essential in sensitive assays. Buying bulk tips is the cheapest option for labs on a budget. Sterile pipette tips are an essential tool for researchers, and their time is precious for scientists and lab technicians. However, if a lab uses several pipettes with many samples, it is essential to purchase sterile tips to prevent the time-consuming task of changing tips in between experiments.

The type of tips used to transfer cellular samples is another important consideration. A standard tip's narrow orifice can damage delicate cellular samples. Wide bore tips are preferable as they reduce flow resistance. A wide bore tip also prevents cell shearing. So, it is important to choose a sterile tip that fits your pipette properly. When shopping for a sterile pipette, always remember to choose a high-quality product. When transferring liquid using a pipette the tip of the pipet should be rinsed and sterilzed with the liquid before using it.

Cole-Parmer sterile pipette tips are manufactured using advanced cleanroom techniques. They are manufactured using high-purity polypropylene and free of chemical additives. A non-self-sealing PE filter helps prevent the transfer of liquids, and a 99% bacterial aerosol filter ensures that the sample remains sterile. They come in a variety of volumes and are GLP compliant.

A multi-channel pipete has a large number of channels. This means it can easily empty a tip box in minutes. Additionally, Racked Sterile Tips are pre-sterilized and are available in boxes to protect against contamination. The convenience and cost-effectiveness of these tips make them an excellent choice for lab work. And, they are compatible with most pipettes. They also have smooth surfaces that ensure accurate pipetting.

A good quality sterile pipette tip is essential for accurate and reproducible results. A cheap tip may have a few small irregularities that are not visible to the naked eye, resulting in inaccurate results. A non-manufacturer tip may not fit pipettes of a certain manufacturer, and researchers should gravimetrically test them to be sure they fit correctly. After all, you don't want to waste time and resources with an incorrect tip!

Choosing the Right Tip of Pipettes

A simple but critical feature of a pipette is its tip. If not chosen properly, the tip of a pipette can completely void its precision. It can lead to contamination, loss of precious samples and reagents, and even repetitive stress injury. Pipettes come with many different types of tips, and it can be difficult to determine which one is best for your experiment. Here are some tips to keep in mind when choosing the right one for your research.

The shape and geometry of the tip of a pipette are of paramount importance when delivering a consistent volume of liquid. An imperfect drop cut-off can cause water retention or impair precision in pipetting, especially if you're dispensing a small volume. To avoid this, choose a tip made of superior materials and free of molding defects. Proper pipette tips are not just aesthetically appealing, but also ensure consistent, accurate results.

The first important characteristic in choosing a pipette tip is the polypropylene blend. A high quality tip is made of virgin polypropylene that contains no plastic or metal additives. If you're using a sample, you want to be sure to choose a tip with no metal additives. If you're using a colored pipette tip, the same principle applies. The tip should also be made of a material that's free of demolding aids and parting agents.

Another factor to consider when choosing pipette tips is their sterility. A sterile tip reduces the risk of cross-contamination and improves the results of your experiments. However, sterile tips are not widely available. Because of this, it is important to choose a product that's made with the highest hygiene standards and is free of DNA. This ensures better results. If you're unsure whether the tip of your pipette is sterile, make sure the packaging is sterile.

In a study of 15 different manufacturers, we found that the performance of pipettes and their tips were very similar. However, one of the competitors' tips was longer than the proprietary tip, and this resulted in a lower precision. These differences may not be present in other tips made by the same manufacturer. However, it's important to remember that the manufacturer's declaration of the quality of a pipette and tip is not necessarily applicable to all of its parts.

Moreover, the tip's orifice and inner surface also determine the retention of the liquid. The rounder the drop is, the higher its surface energy. Rounder drops are less wet, but they do have a higher surface area. The diameter of the tip and its inner surface affects the volume of liquid retained. Hence, the size of the pipette is also an important factor. But, what is more important is its consistency.

Regardless of the type of pipette, tips are an essential part of any laboratory. Pipettes are used in different scientific applications, and regulatory bodies have developed quality standards to ensure the reliability of the equipment. To ensure quality, suppliers should adhere to ISO 8655 standards, and provide essential information about its proper use. So, when buying a pipette, make sure to choose the right tip! This will ensure you get the most out of your purchase.
