The Z216-1205 is the 12-position 5 mL angle rotor for the Hermle Z216 chassis family — engineered around the 5 mL Vacutainer-style clinical-research tube format at 14,000 rpm / 18,624 × g. The Z216 chassis is the larger-capacity microcentrifuge in the Hermle benchtop line; this rotor extends its workflow range from the dominant 1.5/2.0 mL microtube formats up into the 5 mL clinical-research tube class. Per the Z216 catalog, this rotor is "for Z216 series only" — engineered for the Z216 chassis spindle and not interchangeable with other Hermle chassis families.

Compatibility & Configuration
Chassis compatibility — Z216 series only. Engineered for the Z216-M and Z216-MK chassis spindle and chamber geometry. Not interchangeable with Z326-1205, Z326-3015, Z207, Z287, or other Hermle chassis families.
RFID-tagged. Chassis applies the rotor's rated 14,000 rpm cap automatically at insertion.
5 mL Vacutainer-style fit. Standard 5 mL clinical-research tubes (typical 13.5 mm OD Vacutainer-style) fit the rotor's position layout. Confirm tube OD against the rotor spec at order if your workflow uses non-standard 5 mL tube formats.
Z216-1205 vs Z326-1205. Both SKUs share the "1205" suffix indicating "12 × 5 mL" rotor type, but they are different physical rotors for different chassis families. Z216-1205 is Z216-chassis-engineered; Z326-1205 is Z326-chassis-engineered. Confirm chassis at order.
Application Profile
Clinical-research 5 mL Vacutainer batch processing on the Z216 chassis — when the lab's primary instrument is the Z216-M or Z216-MK and the workflow extends from the standard microtube format up to 5 mL clinical-research samples.
5 mL serum/plasma preparation at high RCF — the 18,624 × g ceiling supports clean serum/plasma boundaries in 5 mL clinical-research tube format.
Cold-chain 5 mL workflows on Z216-MK — refrigerated chassis pairing for cold-stable protein and analyte workflows in 5 mL format.
Microfluidic-prep 5 mL aliquots — high-RCF clarification of 5 mL aliquots before downstream microfluidic injection.
Method-development workflows comparing 5 mL vs 1.5/2.0 mL workflow scaling on the same chassis.
Ordering & Configuration
12-tube symmetric loading. Opposite-pair distribution (positions 1+7, 2+8, etc.); pre-balance pairs by weight before insertion.
Z216-1205 ships as the rotor body alone. Specialty tube adapters sold separately if needed.
Confirm Z216 chassis pairing, tube format (confirm 5 mL OD against rotor position spec), training, lead time at quote.
Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the rotor body.
Z216 5 mL workflow note: the Z216-1205 is the dedicated 5 mL pick on the Z216 chassis. For mixed-format workflows that span 1.5/2.0 mL + 5 mL on the Z216, also consider the Z216-2420S COMBI-Rotor (24 microtubes + 4 PCR strips) — different format mix but supports multi-format workflows on the same rotor body.
