General description

Our anhydrous solvents deliver exceptionally low water content, making them theideal choice for moisture-sensitive laboratory applications. Packaged in the exclusive Sure/Seal™ septum bottle system, they are reliably protected against moisture ingress from first use to last drop. The innovative Sure/Seal™ closure combines an advanced plug-style liner with an airtight elastomer and crimp cap design to ensure consistent product integrity. Three unique liner materials provide optimal chemical compatibility across a broad range of solvents. Sure/Seal™ packaging is proven to maintain anhydrous conditions even afterrepeated punctures. With more than 70 products across all major solvent families, available in pack sizes from 100 mL to 2 L, the portfolio meets virtuallyevery laboratory need. By choosing ready-to-use anhydrous solvents in Sure/Seal™ packaging, researchers eliminate the need for time-consuming and hazardous in-house solvent drying and distillation - saving time, reducing risk, and improving reproducibility.

Application

Anhydroussolvents in™ packaging are essential wherever water contaminationwould compromise experimental results. They are widely used inmoisture-sensitive applications such as organic synthesis - including Grignardreactions, organometallic chemistry, and catalysis - as well as in peptide,oligonucleotide, and pharmaceutical synthesis.
Solvent for many hydrophobic organic compounds.
