Sfär is the Swedish word for "sphere", and the name of our columns reflects the fact that we have made spherical silica a standard due to its higher surface area and higher loading capacity. Reliable and flexible, Biotage® Sfär columns deliver larger loading capacities, tighter elution bands and purer fractions than traditional flash columns.
Biotage developed and introduced pre-packed columns for flash purification in 1994. Today our broad selection of columns enables professionals to choose the solution which best suits their purification needs. Biotage® Sfär is a complete portfolio of flash columns, available in a large variety of sizes from 5 g to 350 g and in a range of media types, so you can purify milligrams to multi-grams of your valuable compounds quickly and easily.
Chemistry, by its very nature, involves the use of chemicals that can be harmful, toxic and potentially damaging to the environment. Drug discovery currently has a large and expensive environmental footprint so finding a solution is good for both the chemist and the environment. Our contribution to protect the environment with the new columns is clear.
A first step to a greener purification is using a column with a higher loading capacity, so you can purify the same amount of sample on a smaller column and hence use lower flow rates and less solvent; and ultimately finish the job quicker. This will make your whole process greener, less expensive and also more efficient.
To do that you need a column that has been designed with your needs in mind by the pioneers in flash purification: Biotage® Sfär HC (High Capacity).
Our proprietary silica in Sfär HC delivers increased surface area, no fines, and remarkably low pressure. This means your loading capacity is much higher compared to standard columns, thus reducing purification costs, environmental impact, and making separation faster.
Sfär columns have been designed to tolerate higher pressures, so you can use higher flows to speed up the purification process even further.
The unique design of Biotage® Sfär makes it possible to load your columns in seven different ways, including three different dry loading options thanks to the Biotage Samplet®. For your difficult separations, when you want to utilize dry loading in the most convenient way, take advantage of the orange flower shaped cap of Biotage® Sfär D (Duo).
With Biotage® Sfär D we are introducing additional flexibility in the way columns can be loaded.
The spherical particles in the columns support faster flow rates to speed purification and improve productivity.
When used with Biotage® Selekt, flash purification system the instrument will suggest the optimal cartridge for your conditions and will help you in optimizing the utilization of Sfär columns.
