Experience in purchasing consumables such as pipettes and tips
A pipette can only be used with a good tip! The tip is the most important factor affecting accurate pipetting. The pipette and the tip together form a complete pipetting system.
• Low suction tip:
• Low adsorption pipette tips Compared with ordinary pipette tips, the adsorption of samples is reduced by 3-5 times. The special low-adsorption resin makes the inner surface of the pipette tip more hydrophobic, which significantly reduces the loss of the sample due to adsorption and wall hanging. It has lower liquid adsorption and better pipetting effect. It is beneficial to save expensive reagents and improve the accuracy of pipetting. At the same time, it has 100% material inertness without precipitation.
• Lengthened suction head:
• The extended tip allows you to reach the bottom of test tubes, reaction flasks, flasks and other containers. Avoid touching the inner wall of the sample container with the lower end of the pipette, which not only increases the safety protection for experimenters, but also reduces the probability of sample cross-contamination.
• Filter tip:
• The filter element prevents accidental splashing of liquid into the pipette and prevents aerosols from penetrating into the pipette. It is very suitable for genetic research, forensics, PCR and radioisotope sampling. Thermo Fisher offers two filter tips: self-sealing and non-self-sealing filter tips. The self-sealing tip can prevent the sample from penetrating and protect the pipette from being damaged or contaminated by excessive aspiration.
• Gel spotting tips:
• Applying standard tips to acrylamide or agarose gel is very time-consuming. Suitable for gel electrophoresis and capillary loading.
• Solvent safe charcoal (filter element) tips:
• Solvent-safe carbon fiber filter element. The pipetting tip is suitable for acids, alkalis and corrosive organic solvents. It is the best solution for precision pipetting required by combinatorial chemistry. Strong acids, alkalis and corrosive organic solvents can damage the pipette and cause serious errors. The innovative activated carbon fiber ART filter tip can prevent samples from being damaged by aerosol and vapor without affecting the precision and accuracy of the pipette.
• Wide mouth tip:
• The large opening tip is ideal for genomic DNA, fragile cell lines and other sticky materials. Wide-mouth tips have an opening 70% larger than standard tips, and they provide the flexibility needed to pipette difficult-to-transfer samples. It is specially designed for researchers who study large molecules such as genomic DNA, and is very suitable for transferring samples of fragile cell lines, such as macrophages, hybridoma cells, liver cells, etc. Use standard tip to pipette these samples. When the sample passes through the narrow and narrow hole of the standard tip, the sample will be damaged by mechanical shearing force, causing cell damage and rupture. The use of wide-mouth tips will increase the viability of the seeded cells.
• Individually packaged tips:
• For extremely sensitive pipetting applications, individually packaged tips can be used. The individually packaged sterile tips are suitable for applications that require strict sterility.
