The Yamato 212814 is a 10-piece set of 50 mL serum (vial) bottles with rubber stoppers for the Yamato DC401 freeze dryer — small-volume vials for lyophilizing reagents, media, and biological preparations that seal and store under the freeze-dried stopper. It gives ten 50 mL bottles for vial-format drying; companion sets cover 30 mL (212815) and 10 mL (212816). It is the standard 50 mL serum-vial consumable set for the DC401.

Application Profile
Vial-format freeze-drying produces single-use, sealed lyophilized product — a reagent, medium, or preparation frozen in the vial, dried under vacuum, then sealed by its rubber stopper without air exposure (see cold-chain-sample-storage). The 212814 serum bottles are the 50 mL vials for that workflow on the DC401: the stopper vents vapor part-way during drying, then presses home under vacuum to close the vial, preserving a stable, low-moisture product. Fifty milliliters suits larger doses; the 30 mL (212815) and 10 mL (212816) sets step down for smaller volumes.
Frequently Asked Questions

Ordering & Configuration
add to your DC401 order. Confirm the vial volume (10/30/50 mL) and how many bottles your protocol requires. Add it to your DC401 quote with the appropriate chamber and adapters.
DC401 serum bottles, by volume: the 212814 (50 mL) is the largest vial set; step down to 30 mL (212815) or 10 mL (212816) for smaller doses. Serum-bottle drying suits sealed single-use lyophilized product; flask drying (212560 chamber + dry flasks) suits bulk batches.
