The B4000-28-220 is the 220 V international plug variant of the BioClave 28 Autoclave, identical chassis, steam generator, and operating envelope as the B4000-28-120 (US 120 V plug) parent. Same-price voltage pair at $13,895. Universe naming convention uses -120 / -220 SKU suffixes for the BioClave 28 (vs the "" / -E pattern used by Mini and 18 sisters).
For full chemistry rationale (production-scale sterilization workflows, BioClave family decision, application profile, safety considerations), see the B4000-28-120 (120 V US plug) parent page and the B4000-M (Mini) anchor page.

Frequently Asked Questions
How does the B4000-28-220 differ from the B4000-28-120? Only the electrical configuration. The -220 is the 220 V international-plug variant; both are functionally identical at $13,895.
What is the chamber capacity? 28 L, the largest in the BioClave family.
What is the sterilization mechanism? Pressurized steam at 121 °C.
How do I pick between the two variants? By destination wall outlet; confirm the exact international plug type (Schuko, UK BS 1363, AS/NZS 3112, etc.) at order.
Ordering & Configuration
See B4000-28-120 parent for accessory pairing, water / drainage planning at production-scale, regulatory compliance, chamber-load sizing, and preventative maintenance plan.
Confirm international plug type at order. The -220 suffix indicates international electrical compatibility but specific plug type (Schuko, UK BS 1363, AS/NZS 3112, etc.) varies by destination country. Confirm with Benchmark Scientific tech support at order.
Confirm at quote: destination country / outlet standard, exact plug type, water supply / drainage, regulatory compliance, chamber-load sizing, preventative maintenance, training, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms.
BioClave 28 voltage pair: B4000-28-120 (120 V US) and B4000-28-220 (220 V international) are functionally identical at $13,895 each. Pick by destination wall outlet; confirm international plug type at order.
