The Yamato 212573 is the double-format ampule adapter, supplied 5 pieces per set, for the DC401 benchtop freeze dryer. It mounts ampules onto a DC401 manifold or flask-mounting chamber port so small liquid samples freeze-dry under the trap's shared vacuum — the "double" adapter carries two ampules per port.

| Product name | Ampule Adapter, Double (Yamato 212573) |

Ampule freeze-drying is the classic route for small liquid aliquots — biologicals, reference standards, reagents — sealed after lyophilization for long cold-chain storage. The Yamato 212573 adapter seats ampules on a DC401 manifold port; the double version holds two ampules per station, so a 16-port Manifold B (212562) or 8-port Manifold A (212561) processes many ampules at once. Order the double adapter when you want more ampules per port than the single (212572) but fewer than the triple (212574). Pair with dry flasks, caps, and serum bottles from the DC401 accessory family.
What does "double" mean, and how many come in a set? The double adapter carries two ampules per manifold port, supplied 5 pcs/set. Yamato also lists single (212572) and triple (212574) formats, each 5 pcs.
Which equipment does the 212573 fit? Yamato DC401 freeze-dryer manifolds and the flask-mounting chamber that share the DC401 port standard.
What are the adapter dimensions? The DC401 brochure lists only the format and 5 pcs/set pack for ampule adapters; no individual dimensions are published, so none are stated here.
A small consumable glassware set; add directly to cart with your DC401 glassware order.
Guarantee: Small-item satisfaction guarantee — contact us if the set arrives damaged or incomplete. Typical accessory lead times apply.
DC401 ampule adapters: choose Double (212573) for two ampules per port — step to Single (212572) for one, or Triple (212574) for three, per ampule size and batch density.
