Amber vials are often used for light sensitive compounds and are considered low actinic. The RSA™ Brand Fused Inserts sit slightly above the top lip of the vial. This unique feature allows for a near perfect seal with the cap's septa. These inserts are not attached to the bottom of the vial and do not suffer from cracking at this fused point and prevents leaking which can be observed in competitive brands.

RSA Glass is low adsorbing and will not add Na to sample solutions or compounds that cause pH changes. Click HERE for more information about RSA autosampler vials.

The consistency of the insert's glass chemistry from batch to batch, vial to vial makes this a great choice for low dosage form pharmaceutical preparations. Reduced surface activity is tested for each lot and certified. Excellent choice for low abundance analytes, pH sensitive analytes and for LCMS.
