Biotage® Initiator+ Alstra™

Fully automated, single-channel system designed for fast and flexible synthesis.

Biotage® Initiator+ Alstra™ is a fully automated, single-channel microwave synthesizer for small to large-scale peptide synthesis. Microwave heating accelerates reactions, improving yield and purity while reducing synthesis time. The system supports peptoids, PNAs, and peptidomimetics, with flexible

Disposable reactor vials simplify setup, while digital syringe pumps ensure precise reagent delivery and dual-needle technology reduces cross-contamination risk. Patented oscillating mixing guarantees uniform heat distribution. Optional UV monitoring and microwave-assisted synthesis expand your capa

The 10-inch touch screen and intuitive software simplify operation offer access to pre-defined and custom methods. You can automate full synthesis cycles or control key steps manually. Automate full cycles or control key steps manually. Branches™ simplifies complex modifications, helping chemists ma

The robotic liquid handler minimizes waste and reduces reagent use . Small-scale synthesis from as little as 5 µmol enables further savings. Improved synthesis results lead to fewer chromatography runs, supporting a more sustainable workflow.
