Vial & Cap Kit Includes 100 EA 300ul, Fused Insert with a wide tip, Screw Top, Clear RSA Autosampler Vials with Write on Patch and fill lines and 100 EA matching Screw Caps with White Silicone Rubber / Red PTFE Soft-Guard Septa, bonded in the Blue Caps. MicroSolv Brand Easy Purchase Pack. 1 PK.

The MicroSolv™ Fused Insert vials are made with a 300µl insert that is uniquely fused at the top of the autosampler vial with a small flange that extends above the inner top of the vial opening which provides true sealing of the insert with the cap. Unlike competitors which are not fused at the top, these RSA™ vials will prevent evaporation into the vial and spilling into the vial with the cap on. The write on patch is made with epoxy paint. 

The critical dimension of the bottom depth of the fused insert is designed and QC controlled for the most demanding autosampler to prevent needles hitting the bottom of the insert during runs. Less than 2µl residual volume is common with well maintained injectors. Wide Tip at the bottom of the insert prevent bubble formation when filling quickly or with automation.

These Reduced Surface Activity (RSA™) glass autosampler vials are designed and manufactured with a pristine interior surface that is not coated or treated in any way but lacks the typical silanol sites (hydroxide groups) other vials, even "Certified Vials" will have. This means that basic compounds will not adsorb to your glass before injection thus allowing more accurate and precise data especially when your analytes are in low abundance.

The patent pending RSA™ manufacturing process does not use any grease or additives that causes other vials to increase the pH of water diluents in the vial (over a 4 hour period) by as much as 1.5 pH units. Also, this unique process does not drive metals such as sodium or magnesium to the surface or add any metals which makes them excellent for LCMS, GCMS, Bioanalysis or when metals will chelate with your samples. RSA™ offers unmatched consistent, accurate and reliable results which is especially important when your analyses are critical*.

The Soft-Guard™ Screw Caps that are inlcuded with this kit are knurled on the sides for excellent gripping and comfort when applyting to the vial. The silicone rubber / PTFE septa used were designed to provide the right amount of resistance to autosampler needles during the injection process so that they penetrate the vial properly without damaging the septa or the injection needle. Too much or too little resistance to the needles can damage the septa, compromise resealing, cause needle blockage from coring of the septa material and even damage your autosampler. These septa perform even when using a wide range of needles: fine, blunt or even dull. Low sample or solvent evaporation performance even after multiple injections have been observed when using Soft-Guard™ caps.

Vials and caps are packaged separately inside the kit which includes a clam shell over pack which can be used on the bench to dispense the vials and caps. Each kit includes 100 vials and 100 caps. 1 PK.

 *Certificate of QC compliance is available upon request. Every batch is tested for adsorbance, pH change and metal content maxima.
