Benefits of Micropipette Tips
Contamination prevention
Micropipette tips are designed to be used only once and then discarded. This greatly reduces the risk of contamination from one sample to another, preventing the potential spread of bacteria, viruses, or other hazardous materials that may be present in a sample.
Accuracy and precision
Micropipette tips are manufactured using precision molds, which ensures that each tip is uniform in size and shape. This helps to ensure accurate and precise measurements, especially when working with small volumes.
Time and cost-saving
Using micropipette tips eliminates the need for cleaning and sterilization of pipette tips after each use. This saves time and reduces labor costs associated with cleaning, maintenance, and sterilization of reusable tips.
Convenience
Micropipette tips are available in a wide range of sizes, materials, and types, which makes them suitable for different types of samples and applications. They are also easy to replace, reducing the risk of pipetting errors due to worn or damaged tips.
Types of Micropipette Tips
Filter vs non-filter
Filter tips: Filter tips are generally meant for use in specific kinds of tests. For instance, if the sample is corrosive or volatile or highly viscous in nature, it can potentially damage the pipette. In such cases, filter tips are recommended for use. The filter placed inside these tips would help prevent the chances of excess aspiration of the sample, which is responsible for inducing damage to the pipette shaft. Every time you aspirate liquid, aerosols are generated inside the pipette tip. If you don't use filter tips, these aerosols are likely to contaminate your pipette and the subsequent samples. A filter pipette is also recommended for novice lab technicians or university students, who lack the requisite experience of handling pipettes. They can be used for training purposes as filter pipette tips protect against potential damage or contamination of samples, and therefore, prove to be highly cost-effective.
Non-filter tips: Non-filter tips are the major type of tips used in any lab as they are less expensive than filter tips. Non-filter tips lack the advantages associated with filter tips, therefore, are more suitable for samples that are not susceptible to contamination, and that is unlikely to damage the pipette. In addition, these non-filter tips can be used by people who have a significant amount of experience handling pipettes in the lab. Moreover, one can use non-filter pipette tips for relatively non-sensitive applications, such as isolating plasmid DNA, and loading agarose gels, among others.
By packaging
Racked: Today, micropipette tips are primarily available as pre-filled stackable racks, usually made of polypropylene. As the micropipette tips are well-stacked, they don't require to be manually emptied in a sterile container. The racks are sturdy, having thick walls, and usually come with a transparent lid and base. Once emptied, the racks are reusable.
Bulk: Bulk tips are usually packed in zip-locked resealable polyethylene bags. The zip-lock sealing offers superior protection against contamination. After you receive your bulk package, you can manually empty your pipette tips in a sterile box.
Reloads: Reload packaging is similar to racked tips, however, it is much more sustainable and environment-friendly as the same box can be used with replaceable reloads. It generally comes with a unique nestable design, making it a compact and contamination-free option.
Individually wrapped: Individually wrapped pipette tips are used in studies requiring highly stringent aseptic conditions. The single-wrap packaged tips are used across a variety of sensitive applications to ensure sterility and safety. Such type of packaging is free from endotoxins, or any other biological contaminants, thereby possessing the utmost sterility standards.
Low retention vs. Non-low retention
Low-retention tips can be manufactured using a variety of techniques. For instance, in one of the manufacturing processes, the tips are mechanically polished with the help of a diamond abrasive to render them extremely smooth. This prevents liquid samples from sticking to the tip surface.
Additionally, some manufacturers use plastic additives or surface-modifying chemicals to alter the properties of the polymer. These chemicals are either added to the polymer material or are coated onto the plastic surface. However, the latter technique poses a risk of leaching of chemicals into the solution, which, in turn, can cause contamination of the sample. Further, the coating process might lead to uneven coverage of the chemical on the tip's surface. This can result in inconsistent pipetting results.
By dimensions
Macro tips: These tips are primarily used for carrying out pipetting of large liquid volumes safely and efficiently. Macro tips are able to handle reagents in a volume ranging from 5 ml to 10 ml.
Micro tips: Micro tips are used to transfer relatively smaller liquid volumes, mostly in the range of 0.5 ul to 1,250 μl.
Ultra-micro tips: Ultra micropipette tips are available for use in pipettors of the size range 0.5-20 μL.
Wide orifice: As the name suggests, these pipettes are designed with a larger tip orifice. This characteristic is particularly useful for eliminating cell shearing and flow resistance. With an orifice almost 70% greater than a standard pipette tip, these tips offer significant flexibility required for handling difficult-to-pipette samples, such as fragile cell lines, genomic DNA, macrophages, hepatocytes, hybridomas and other highly viscous liquids. These samples are not suitable to be transferred through a standard tip's orifice as they are subjected to mechanical shearing force, which can lead to fragmentation to the cells in the pipette. Therefore, wide orifice tips are instrumental in ensuring cell viability and plating capability.
Short vs. Extended length
Short tips: Short tips are used to fill small wells, for instance, while pipetting in a 384 or 1,536 well-plate. In addition, they offer better ergonomic properties as they enable you to pipette closer to the bench, thereby, minimizing arm strain.
Extended length tips: Micropipette tips having extended lengths offer significant contamination control as they enable you to reach to the bottom of the vessel, thereby reducing contact of the container with the pipette shaft. These tips are better than standard tips and are suitable for labware, including microcentrifuge tubes or deep good blocks.
Beveled tips: A beveled orifice prevents adherence of the sample to the tip, and makes it easier to pipette every drop of the sample entirely. In the process of gel loading, a beveled tip is useful in preventing accidental damage of the gel. Beveled tips are also useful for accurate fluid transfer as they usually have graduation marks.
Round and flat tips: Flat and round tips enable easy access into vertical and horizontal electrophoresis gels. Flat tips are used primarily for loading acrylamide and agarose gels in the process of gel electrophoresis, whereas round tips are better suited for loading SDS PAGE and agarose gels.
By special applications
Gel loading: Loading acrylamide or agarose gels with standard pipette tips is a cumbersome process, and can lead to significant pipetting errors. Usually, round tips are used for loading agarose gels, and ultra round / flat tips are used for polyacrylamide gels.
Blood samples: Blood and plasma comprise of proteins that pose the risk of wetting the surface of a pipette tip, thereby causing foaming. This makes the process of pipetting very time-consuming and can cause contamination, specifically in point-of-care diagnostics applications. Therefore, for such purposes, a wide orifice tip is generally used.
Positive displacement pipette tips: In such pipettes, there is direct contact of the piston with the sample without any air cushion. The disposable piston is part of the tip, and not exactly integrated in the pipette. Therefore, it is recommended for difficult-to-handle samples (viscous, volatile, corrosive, dense, radioactive, extremely hot/cold).
Repeater pipette tips: Repeater pipettes enable the user to easily perform a number of repetitive dispensing cycles. Repeater pipette provides reliable ergonomics without compromising on precision. Pipette tips used for such pipettes are reliable and maintenance-free with a robust design, so as to endure the mechanical burden imposed by repeated pipetting. The tips are manufactured using high-quality virgin plastics, and without any chemical additives in order to prevent any type of contamination.
Robotic pipette tips: Tips for automated workstations are subject to stricter tolerances than standard pipette tips. Robotic pipette tips can be implemented with automatic liquid-handling workstations. Some tips may be designed for specific robotic systems and robotic tips are regulated under tighter tolerances compared to handheld pipettes.
The first and foremost characteristic important to selecting a micropipette tips is the polypropylene blend of the tip. Generally, high-quality tips are made using virgin polypropylene material. This polymer is free from metal / plastic additives that are potential contaminants for your samples. Especially for colored tips, it's necessary that the manufacturer is not using metal additives as such additives are often added in the dyes used in the coloring process of these tips.
