Frequently Asked Questions (FAQs)
For very polar compounds, including ionizable biomolecules and inorganic ions, the use of a plastic vial may be considered. Polypropylene vials are included in the SureSTART range as a Level 1 range of products.
Most polar analytes can be analyzed successfully in glass vials with few problems at normal analytical levels. Low concentrations may require investigation of deactivated vials, but in most cases the control of the sample pH is enough to maintain linearity.
Type 1 neutral borosilicate glass is suitable for neutral/acid samples with little change of pH caused by the glass surface.
For analysis of compounds which show interactions with untreated glass surfaces, it may be necessary to use a deactivated glass vial. The effect of adsorption is most apparent when dealing with very low concentrations of the sample. It is likely that this effect will only be identified during calibration. Analytical results will show poor reproducibility and linearity for active samples while non-adsorbing species show good results.
Inert glass products can be found in Performance level 3, and include silanized glass and GOLD-grade technology deactivated glass.
