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.
In addition to the features on standard 2 mL vials, SureStop vials also have a patented definite stop point (alignment ring) in the design of the vial finish. This prevents the vial from being an optimal seal, which eliminates under- and over-sealing by the cap/closure and user-to-user variance.
SureStop vials are designed for use with Advanced Vial Closure System (AVCS) screw caps. They improve transfer reliability and give a more secure liquid seal than standard screw vials. SureStop vials are available as a 2 mL as either clear or amber options and are highly recommended for use with GC and LC applications.
