Recommended Shelf Lives and Storage Conditions
 

A range of specially dried and chemically pure solvents featuring such low water levels that surpass even the so-called anhydrous offerings from rivals. Bottles are fitted with a specially designed cap that both aids dispensing whilst retaining solvent dryness. Also, as an aid to maintaining dryness during use, a number of solvents are available stored over molecular sieve. Choose the pack most suitable for your application out of a wide range of sizes: 100ml, 250ml, 500ml, 1LT, 2½LT. Bulk packaging is available in the form of ROMIL LiQuiSure™ stainless steel flasks. The water content itself is strictly controlled by coulometric Karl Fischer and we print the actual batch result on every Hi-Dry® label so that you can discover for yourself just how dry these solvents really are.

¹ This solvent is packed in HDPE (high density polyethylene) bottles because it has a relatively high freezing point (+25°C) and, like water, it expands on freezing. This action can cause glass containers to break. Note that all sizes are available in HDPE, except 250ml.
