Nearly eliminate septa push-through and improve sealing with Advanced Vial Closure System technology. This innovation not only prevents septa push-through, but provides a stop point for the cap to prevent over - or under-tightening and provide an optimal, consistent seal every time. Vials are made from superior quality 33 expansion borosilicate clear Type 1, Class A glass, and meet all US, EU, and JPN Pharmacopia standards.

• Closure system prevents septa push-through
• Wide neck opening

Fill vials easily with the wide neck opening; requires 6 mm diameter micro-inserts.

Thermo Scientific National Preassembled Target DP Kits include 100 2 ml vials with pre-attached caps and septa. Packaged in convenient vial trays with clear covers or in polybags.

Get maximum sample extraction without the need for separate inserts by using Microsampling and High Recovery Vials. Identify sample and volume with graduated, write-on patch provided on certain vials. Obtain maximum recovery of critical polar, labile or OH-interacting compounds using silanized (deactivated) glass (optional). The polyspring microseal inserts self-align and provide a cushion against needle contact. Precision point inserts minimize residual sample loss. Pulled point inserts provide an economical choice for noncritical applications. Vials provide the sealing and performance of a crimp top vial. The Sure Stop vial design incorporates a definite stopping point in the vial finish and removes all subjectivity in achieving optimal seal compression closing a vial. Prevents over- or under-tightening of closures and gives an optimal seal every time. Recommended for most brands of autosampler.
