Nanopositioners are investments that your lab cannot avoid making, especially if you work in a college or university setting. They are vital for different experiments and can allow your faculty, staff, and students to compete with those in other institutions. You may already have nanopositioning stages, but when your budget allows, you need to re-evaluate them and decide whether to buy new ones. If you do start looking for new nanopositioners for sale, be most focused on these qualities.
Depending on how long it's been since your department purchased new nanopositioners, you may be delighted and surprised to discover how much faster nanopositioners are able to work. Faster nanopositioning stages permit users to more accurately capture images. If your institution has people who work on moving particles regularly, you can do them a real service by looking for models that are among the fastest on the market. The increased ability to monitor and observe moving particles will enable accurate and specific conclusions, which will better fuel their work and the reputation of your lab and school.
Newer nanopositioners today also allow for closer focus. Among other benefits of better vision, descriptions of particles will be more detailed and accurate. This will give your students and staff greater visibility that will also enhance papers, labs, and other work.
Older nanopositioning stages may have operated on the regular, standard X-axis and Y-axis. However, newer models have capabilities to also display the Z-axis. This means better images and better observations for users.
Better Heat Control
One reason you may have agreed to shop for new nanopositioners is that the ones currently sitting in your lab have to be repaired often and finding parts is becoming more and more difficult. In particular, heat control may have been a problem you were experiencing.
Luckily, many new models offer improved heat control so that repairs are not needed so much. Some models utilize simple air bearings that keep friction levels low when users operate the equipment. Wide, large photographs render easily. If, like many labs, you work with particles that don't require air--anaerobic particles--air bearings are untenable. In that case, you'll need models which use flexures. Just know that photographs from those models are likely to be somewhat smaller than you'd see with other models.
New equipment for your lab is probably greeted with positive feedback from those who will use it. With the way that new nanopositioners will enhance the research done by everyone in your school, people will be even more excited. Talk with everyone both before and after purchasing new pieces and work with retailers along the way to know you're getting the appropriate equipment for your institution
