The Yamato 212560 is the 12-port flask-mounting chamber for the Yamato DC401 freeze dryer — the accessory that turns the DC401's cold trap into a small parallel dryer, letting up to twelve pre-frozen flasks dry simultaneously off one refrigeration system via twelve valved ports (18.5 mm I.D. stoppers at 96 mm pitch). It is the standard flask chamber for labs standardizing on flask-drying with the DC401.

Application Profile
On its own the DC401's −45 °C trap is a condenser that protects the vacuum pump; the 212560 flask-mounting chamber makes it a *dryer*, adding twelve valved ports so up to a dozen pre-frozen flasks dry in parallel off one refrigeration system (see cold-chain-sample-storage). Each port takes a dry flask through the DC401's glass joints, with 18.5 mm-I.D. stoppers at 96 mm pitch spacing flasks so vapor draws evenly — the right accessory for flask-format lyophilization of reagents, media, extracts, and biological preparations in batches (see cold-storage-selection).
Frequently Asked Questions
What does the 212560 do? It mounts on the DC401 freeze dryer to hold up to twelve pre-frozen flasks, so they lyophilize in parallel off the single −45 °C trap.
Which dryer does it fit? The Yamato DC401 freeze dryer.
What size flasks does it take? Flasks with the DC401's standard glass joints, seated in 18.5 mm-I.D. stopper ports at 96 mm pitch. Dry flasks (120 mL, 250 mL) and caps are ordered separately.
Ordering & Configuration
add to your DC401 order. The 212560 is a core freeze-dryer accessory. Confirm your dryer is the DC401 and select the dry flasks and caps you need to load it. Add it to your DC401 quote to build a flask-drying configuration.
DC401 chamber options: the 212560 12-port flask chamber maximizes parallel flask capacity; Manifold A (8-port), Manifold B (16-port), and a closed dry chamber are alternatives for different formats.
