40nm Silica Nanoparticles
Available in both powder (10g, 50g and 100g) or dispersion (100ml and 500ml of 10wt% SiO2 in H2O) – with Certificate of Analysis
GE&R silica nanoparticles are manufactured and characterized using state-of-the-art techniques to deliver high purity (>99.9% SiO2) and narrow size distribution. These silicon dioxide nanoparticles are spherical and can be dispersed into various solutions.
Trial Kits contain quantities (1g, 5g, or 25ml) of all five sizes (20nm, 40nm, 80nm, 120nm, 200nm).
