The Z216-1220H is a 12-position swing-out rotor for HLA / 1.5/2.0 mL workflows on the Hermle Z216-M MicroCentrifuge chassis (note: per universe spec, Z216-M only — not the refrigerated Z216-MK). The HLA designation indicates Hematology / clinical-research format compatibility — the rotor is engineered for cell-pelleting workflows where the slower 9,000 rpm / 7,510 × g RCF and true 90° swing-out geometry produce horizontal phase boundaries for clean serum/plasma separation in microtube format. Hermetically sealed for biosafety-spec workflows.

Compatibility & Configuration
Chassis compatibility — Z216-M only. This rotor is engineered for the Z216-M chassis spindle and chamber geometry per the universe SKU description. Not compatible with the refrigerated Z216-MK (despite chassis-family naming similarity), and not with other Hermle chassis families. Confirm at order — the chassis pairing is unusually narrow for this rotor.
True 90° swing-out geometry. Distinct from the angle-rotor geometry of most Z216 microtube rotors — at full speed, microtubes orient horizontally rather than at the standard 45° fixed angle. The horizontal orientation produces clean phase boundaries for serum/plasma separation in microtube format, useful for clinical-research workflows that need swing-out boundary clarity at the small-tube scale.
HLA (Hematology / clinical-research) format compatibility. The 9,000 rpm / 7,510 × g RCF range matches the slower-RCF cell-pelleting protocols used in clinical-research hematology (HLA typing prep, lymphocyte isolation, cell-pellet recovery from small primary blood-collection volumes).
Hermetically sealed lid for biosafety-spec workflows where aerosol containment matters across microtube centrifugation. Standard for clinical-research handling of potentially infectious patient samples in microtube format.
Application Profile
HLA-typing sample prep in clinical-research and tissue-typing labs — small-volume primary samples spun at HLA-protocol-specified RCF in horizontal swing-out geometry.
Lymphocyte isolation at the microtube scale — slower-RCF gentle pelleting with horizontal phase-boundary clarity.
Clinical-research serum/plasma separation in microtube format — when the workflow uses 1.5/2.0 mL primary microtubes (vs 5+ mL clinical Vacutainer formats) and needs swing-out boundary clarity rather than angle-rotor pelleting.
Biosafety microtube workflows — hermetic sealing supports BSL-2+ handling.
Ordering & Configuration
12-tube symmetric loading. Opposite-pair distribution; pre-balance pairs by mass.
Lid torque per Hermle service instructions before each spin.
Z216-1220H ships as the rotor body + hermetically sealed lid.
Confirm Z216-M chassis pairing (note: not Z216-MK), training, lead time at quote.
Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the rotor body and lid.
Z216-M-specific rotor: the Z216-1220H is one of the few rotors in the Hermle catalog specified for a single chassis model (Z216-M) rather than the broader chassis family. If your lab has the Z216-MK refrigerated chassis instead of the Z216-M, this rotor will not pair — confirm chassis at order.
