Classification of laboratory pipette tips

Classification of laboratory pipette tips

they can be divided into the following types: Standard tips, filter tips, low aspiration tips, tips for automatic workstations and wide-mouth tips.The tip is specifically designed to reduce residual adsorption of the sample during the pipetting process. It is a laboratory consumable that can be used in conjunction with the pipette. It is mainly used in various pipetting scenarios.

1.Universal Pipette Tips

Universal Pipette Tips are the most widely used tips, which can be used for almost all pipetting operations, and they are also the most economical type of tips. In general, standard tips can cover most pipetting operations. other types of tips have also evolved from standard tips. There are generally many forms of packaging for standard tips, and there are three common types on the market: in bags, in boxes, and in pre-installed plates (stacked).
When users use it, if they have special requirements for sterilization, they can buy sterilized boxes directly. , or place unsterilized pouch tips in an empty tip box for self-sterilization before use.

2.Filtered Tips

Filtered tips is a consumable designed to prevent cross-infection. The sample picked up by the filter tip cannot get inside the pipette, so the parts of the pipette are protected from contamination and corrosion. More importantly, it can also ensure that there is no cross-contamination between samples and is widely used in experiments such as molecular biology, cytology and viruses.

3.Low Retention Pipette Tips

For experiments that require high sensitivity, or for valuable samples or reagents that are prone to residues, you can choose low adsorption tips to improve recovery. There are cases where more is left over. No matter what type of tip you choose, a low residue rate is key.

If we carefully observe the use process of the tip, we will find that when the liquid is discharged, there is always a part that cannot be drained and remains in the tip. This introduces some error in the results no matter which experiment is performed. If this error is within an acceptable range, you can still choose to use normal prompts.If we carefully observe the use process of the tip, we will find that when the liquid is discharged, there is always a part that cannot be drained and remains in the tip.

4.Robotic Pipette Tips

The tip workstation is mainly matched with the liquid workstation, which can detect the liquid level and ensure the accuracy of pipetting. High-throughput pipettes commonly used in genomics, proteomics, cytomics, immunoassay, metabolomics, biopharmaceutical research and development, etc. Popular imported workstation brands include Tecan, Hamilton, Beckman, Platinum Elmer (PE) and Agilent. The workstations of these five brands have almost monopolized the entire industry.

5. Wide mouth pipette tips

Wide-mouth tips are ideal for pipetting viscous materials, genomic DNA, and Cell Culture fluids; they differ from regular tips by having a larger opening at the bottom for easier deflation and smaller mechanisms. cut. When pipetting viscous substances, the traditional suction head has a small opening at the bottom, which is not easy to pick up and drip, and also causes high residue. The flared design facilitates handling of such samples.

In the face of genomic DNA and fragile cell samples, if the opening is too small, it is easy to damage the sample and cause cell rupture during operation. Trumpet tips with approximately 70% larger opening than standard tips are optimal for pipetting fragile samples. Excellent solution.
