Free samples

SILIQUAN offers free samples to first-time buyers and loyal clients. Meeting the requirements of the most exacting clients we offer an opportunity to test our products, prior to their purchase.

Each scientific institution and firm is entitled to one free sample of selected products per year. In return we ask that you complete our survey, that will give us a better insight into the market characteristics. Raising standards, as well as adjustment to the requirements of our clients is very important to us.

As free samples we offer 40 nm fluorescent silica nanoparticles with Rhodamine B dye incorporated within the core structure. The surface of nanoparticles may be coated with one ligand of choice: PEG ligand or the amine terminated alkyl chain.
