Vials, Snap Top, Glass. Clear / Clear Insert, 300ul with Write-On Patch and fill lines, Fused Insert™. An 11mm snap ring and 12x32mm outer dimensions. For use as an autosampler vial. RSA Brand. 100/PK.
Vial and Inserts are first hydrolytic, Class A, Type-33 Reduced Surface Activity Borosilicate Glass. Write-On Patch and fill lines are ceramic and will resist smearing or scratching when working with solvents.
Bottom depths and heights are designed and QC controlled for maximum recovery and needle safety. The RSA™ Brand Fused Inserts sit slightly above the top lip of the vial and this unique feature allows for a much better 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 may be observed in competitive brands.
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.
This is a very popular Snap Top, Fused Insert autosampler vial because of the consistency of the glass chemistry from batch to batch, vial to vial. Reduced surface activity is tested for each lot and certified. Excellent for low abundance analytes, pH sensitive analytes and for LCMS.
