Thermocyclers, or thermal cyclers, are instruments used to amplify DNA and RNA samples by the polymerase chain reaction (PCR). The thermocycler raises and lowers the temperature of the samples in a holding block in discrete, pre-programmed steps, allowing for denaturation and reannealing of samples with various reagents. Amplified genetic material can be used in many downstream applications such as cloning, sequencing, expression analysis, and genotyping.
Analytical and Top Loading Balances: Our Precisa analytical balances and top loading balances couple premium workmanship of robust die-cast aluminum housing with the finest engineering materials, providing excellent protection against mechanical and electrical interference.
Cryogenic freezing is a process of cold preservation that is accomplished with very low temperatures. We’re talking a bone-chilling -238° F or -150° C. The storage method is derived from the science of cryogenics, which is about creating very cold environments and studying what the results are for samples that experience extremely low temperatures.
The term Tissue Culture may not evoke the most exciting of visions as a scientific pursuit, but the reality couldn't be more different. Think of scientists working in labs, coaxing life in Petri dishes from a few cells, and you begin to have a glimpse of what tissue culture is all about. When you are growing tissue or cells separately from the organism where they originated, that's Tissue Culture. The growth is usually promoted by using a growth medium, such as broth or agar. Tissue culture, a term invented by an early 20th century Midwestern pathologist, revolves specifically around the growth of animal and cell tissues. Plant tissue culture refers specifically to plants.
The science of biology has its origins in the early scientific work of two centuries ago. It began with a German zoologist named Wilhelm Roux, who removed part of a chicken embryo and kept it alive in saline for several days in 1885. Next, another zoologist grew nerve cells from a frog embryo cell set. By the 1990s, regenerative tissue replaced a small piece of a urethra and mammalian embryonic stem cell growth was developed. The same principles applied to plant tissue culture, where it was posited as early as 1902 that every plant cell had the capacity to develop a whole plant.
Setting up or adding new equipment to a laboratory can be a daunting prospect, at best. There are so many models at so many price points, and the budget numbers can really start adding up.
While there are many types of equipment and materials necessary to fully outfit any lab, some of the most important components of any lab is the mixing equipment, such as rockers and rollers. Fret not! Here is a guide to purchasing all the right rockers and rollers.
When operating a centrifuge, there are things you can do to that will help ensure your success. Here is a guide to help you keep your centrifuge process on track.
Using the right size tube for the correct centrifuge is imperative for the success of your analysis. There are many different types of centrifuges out there and knowing which one you need is very important.
