Use Thermo Scientific 11 mm Crimp/Snap Top Vials with snap caps or aluminum crimp seal closures. These high-quality 11mm glass vials are 2 mL, 12 x 32 mm and fit most brands of autosamplers. Made of superior quality 33 expansion borosilicate clear Type 1, Class A or 51A Type 1, Class B amber glass, they meet all requirements of US, EU, and JPN Pharmacopia.
Easy-to-fill wide-neck opening vials require 6 mm diameter micro-inserts. Identify sample and volume with graduated, write-on patch provided on certain vials. Get maximum sample extraction without the need for separate inserts by using Microsampling and High Recovery Vials. Obtain optimal recovery of critical polar, labile or OH-interacting compounds using silanized (deactivated) glass (optional). Polyspring inserts are self-aligning and provide a cushion against needle contact. Precision point inserts minimize residual sample loss. Pulled point inserts are an economical choice for noncritical applications. Compatible with most HPLC and GC autosamplers.
