Amber vials are often used for light sensitive compounds and are considered low actinic. The AQ™ 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..
