The Z216-2420 is the 24-position microcentrifuge rotor for the Hermle Z216 chassis family — engineered around the standard 1.5/2.0 mL microtube format that dominates molecular-biology bench work. Per the universe SKU description, this rotor is hermetically sealed; the Z216 catalog also lists a Z216-2420H variant with explicit hermetic-sealed labeling. At 14,000 rpm / 18,624 × g across 24 microtubes per cycle, this rotor handles routine batch microtube prep on the Z216-M and Z216-MK chassis.

Compatibility & Configuration
Chassis compatibility — Z216 series only. Engineered for the Z216-M and Z216-MK chassis. Not interchangeable with similar-numbered rotors on other Hermle chassis families.
RFID-tagged. Chassis applies the rated 14,000 rpm cap automatically at insertion.
24-position microtube layout. Standard Eppendorf-style 11 mm OD microtubes fit directly. The 45° angle is the standard high-RCF microcentrifuge geometry.
Hermetic sealing supports biosafety workflows where aerosol containment matters across batch microtube processing — clinical-research samples, infectious-disease research, volatile-content prep.
Application Profile
Batch nucleic-acid prep on Z216 chassis — 24-sample-per-cycle pelleting for DNA / RNA / plasmid extraction, PCR cleanup, miniprep elution.
Protein precipitation at 18,624 × g across 24 aliquots per cycle — TCA, acetone, ammonium-sulfate workflows.
Cold-chain microtube workflows on Z216-MK — combines 24-tube throughput with refrigerated chamber temperature control.
Biosafety microtube workflows. Hermetic sealing supports BSL-2+ workflows handling potentially infectious patient samples in microtube format.
Ordering & Configuration
24-tube symmetric loading. Opposite-pair distribution; pre-balance pairs by mass.
Z216-2420 ships as the rotor body + sealed lid.
