For scientists who conduct research using long pipette tips, there are several factors to consider. Pipettes are commonly used in laboratories, and their use spans a wide range of scientific applications. To ensure quality, regulatory bodies have set high standards for pipettes. To achieve this, manufacturers must meet or exceed ISO 8655 standards for their pipette tips. In addition, they must offer essential information about proper pipette use.
Quality: Quality pipette tips are essential for research, but you must also ensure the tips fit your pipettes. Make sure you choose the original manufacturer's tip for each pipette. You may be tempted to buy cheap, generic tips, but they can lead to inaccurate results. Even if you are able to find the same tip, make sure it fits your pipette. You should also make sure it fits properly if you are not able to find the original manufacturer's tips.
Short and long tips are both effective for pipetting. Short tips allow you to fill small wells with less force and minimize arm strain. Long tips can be used for deeper well blocks and microcentrifuge tubes. Extended tips can be used for high-quality work. The advantages of long pipette tips are outlined below. So, which one is right for you? Let us take a look at each option.
High-quality tips can improve your results. Those with high recovery rates can reach the bottom of a low-spherical container without touching the edge of the container. High-quality tips are also resistant to chemical agents and do not contain leachables. These types of tips can be used for sensitive biological studies such as protein analysis and SDS-PAGE. If you are in the market for a new long pipette tip, consider Avantor.
Pre-filled plastic pipette tips are available. These are typically made of polypropylene and do not require manual emptying. They also have thick walls. Lastly, they are packaged in zip lock polyethylene bags to prevent contamination. These tips are typically safe for your samples and do not contain any metal additives. If you want to purchase colored tips, make sure they are free of metal additives. The metal additives in colored tips can leach toxic chemicals into your liquids, which can compromise your work. Whenever you need to fill up a rack of pipette tips, you should consider using an automatic pipette tip refill system. It can reduce the waste of paper and plastic materials while increasing productivity by eliminating wasteful procedures. The reusable tip racks are compatible with most 0.1 to 200 ul and 50-1250 ul pipette tip racks. Tip Loader is a fully automatical pipette tip sorting device specially designed for bulk pipette tip refill.
Wide orifice pipettes have a larger orifice than standard tips. These pipes can be more flexible and are especially useful when pipetting samples that are difficult to pipette. Standard pipette tips are susceptible to damage from mechanical shearing force, which may cause fragmentation. Wide orifice pipettes help you maintain the viability of your cells during the loading process and can be used for plating.
Extended length pipettes are available as standalone options or for use with LTS pipettes. The length of these tubes makes it easier to pipette into narrow vessels, which is not possible with standard tips. While long pipette tips are narrower, they have no negative impact on accuracy. They are often used with narrow septa to avoid cross contamination. You can find these tips in Rainin's extended-length pipettes and racks.
Eppendorf Dual Filter T.I.P.S. filter tips are the first to feature a two-phase filter for complete contamination protection. They are characterized by low wettability and thermal stability, and are PCR clean certified. These filters feature a dual-phase structure that effectively traps virtually all aerosols and droplets. A defined air passage rate allows you to pipette your sample quickly and reliably, ensuring full sample recovery and a high-quality PCR.
To ensure compliance with local regulations, labs should separate non-critical waste from critical waste. Using two separate containers for disposal of these tips is best practice. The difference between critical and non-critical wastes may be confusing, so it's best to clearly define what each type is. You may also need to consider local regulations regarding disposal of hazardous materials and how they should be disposed. This way, you won't end up with a hazard to the environment.
If you are using a laboratory instrument with a tip, you will probably want to use a filter that has two phases. Using the ep Dual Filter T.I.P.S. tips will protect your samples from aerosols and other contaminants. These filter tips are flexible and hydrophobic, allowing them to fit perfectly in the tip cone. They also have a seal to prevent drops and aerosols from getting in the tip.
If you're not familiar with these filters, they come in colorless, blue, and 76-mm sizes. These filters are available with HEPA/EPA certified filters and a choice of standard, biohazard, or ion-exchangeable cartridges. These tips are highly useful for applications where contamination and leakage are a concern. They are also very easy to use and come with a handy storage case to hold them in place.
