Opis

General description

Our anhydrous solvents deliver exceptionally low water content, making them the ideal 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 after repeated punctures. With more than 70 products across all major solvent families, available in pack sizes from 100 mL to 2 L, the portfolio meets virtually every 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

Anhydrous solvents in Sure/Seal^™ packaging are essential wherever water contamination would compromise experimental results. They are widely used in moisture-sensitive applications such as organic synthesis - including Grignard reactions, organometallic chemistry, and catalysis - as well as in peptide, oligonucleotide, and pharmaceutical synthesis.
