Application Profile
Ampule freeze-drying preserves many small liquid aliquots — reference standards, biologicals, reagents — that will later be flame-sealed for long-term storage. An ampule adapter mounts the ampules on the manifold so vacuum and sublimation reach each one. The triple adapter (212574) holds three ampules per adapter, so a 5-pack dries up to fifteen ampules — the high-throughput option versus the single (212572) or double (212573) adapters. Pair with the straight (212598) or 45° bent (212599) glass joints as needed.
