Chromatography Autosampler Vial Caps Only

Microsolv Technology Corporation Caps, Snap Top, with 1.00mm thick, White Silicone Rubber / Red PTFE Pre-Slit (Y Shape) Septa, fitted in smooth, soft polyethylene, Blue Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 100/PK.
Soft polyethylene caps are more pliable than other Snap Caps and are easier to place on the vial. Popular choice when using a large number of caps at one time. These caps may not seal as well as other Snap Caps and should be used with sample solvents with low volatility. Y Shape Pre-Slit provides a greater target area for needles and are easier to penetrate and the 1.0mm Septa is thicker than most and offers improved sealing compared with other Pre-Slit Septa. Pre-Slit Septa are normally recommended for Waters Alliance and Acquity instruments.
