We offer Silanized Glass Vials

Why are they used?
• Hydrophobic siliconizing agents prevent losses of basic polar compounds and active bio-molecules on glass surfaces.
• Protein losses on glassware can be significant when working with small amounts of protein. It is very useful for protein
chemistry applications because its working solution is prepared in water and does not require dilution in hazardous non-
polar organic solvents. Be aware that some proteins are lost on hydrophobic surfaces more readily than on hydrophilic
• With vials used for concentration with small volume, the deactivation improves total recovery of polar components.
• With micro-sampling, recovery of active components is improved giving greater accuracy and precision.

Siltek Coated Vials
For a highly inert surface, we recommend Siltek® deactivation for your vials:
• Maximizes inertness, minimizes sample breakdown—ideal for difficult matrices and reactive compounds.
• Inert over a wide sample pH range.
• Low bleed.
• Thermally stable.
• Any glass vial can be coated.

Ultra Low Metal Tubes for Storage and Analysis
The metal free centrifuge tubes are produced to ensure that key trace metals are kept below one part per billion (ppb).
They can be used for storage and analysis tasks that require extremely low levels of most common metals.
