Single Ampule Adapter, 5-Pack, for DC401 Freeze Dryer

The Yamato 212572 is a 5-piece set of single ampule adapters for the Yamato DC401 freeze dryer manifold. Each adapter connects an ampule to a manifold port, letting a lab lyophilize small-volume samples directly in ampules that can then be flame-sealed under vacuum for long-term, sterile storage.

Key Specifications

Application Profile

Ampule lyophilization is the format of choice when samples must be dried, then hermetically sealed under vacuum, reference standards, biologicals, and long-shelf-life reagents where a flame-sealed glass ampule gives the best barrier against moisture and oxygen. The single ampule adapter attaches one ampule to a DC401 manifold port; a set of five equips several ports at once for parallel drying. After drying, the ampule can be sealed at the constriction while still under vacuum. Pre-freeze the sample below its eutectic point before drawing vacuum, and load ports in staggered fashion so the trap vacuum recovers.

Frequently Asked Questions

What does this adapter do? It connects a single ampule to a DC401 manifold port so small-volume samples can be freeze-dried and then flame-sealed under vacuum.

How many come in a set? Five single adapters per set (212572). A double adapter version is available as 212573.

Which freeze dryer does it fit? The Yamato DC401, used with Manifold A (212561) or the DC401 flask/manifold configuration.

Why lyophilize in ampules? A flame-sealed ampule gives the best long-term barrier against moisture and oxygen, ideal for reference standards and biologicals.

Ordering & Configuration

Confirm at quote your DC401 manifold configuration and whether you need the single (212572) or double (212573) adapters, plus how many ports you intend to run.

Warranty: Per Yamato standard terms.

Positioning: 212572 is the single ampule adapter 5-pack for DC401 ampule lyophilization. Order it for sealed small-volume drying; choose the double adapter (212573) to double ampules per port, or serum bottles (212815) for stoppered-vial drying.
