0.4 mL High-Speed Adapter for Z326-1220H Rotor (6/pk)

The Z36-04-HS is a 0.4 mL high-speed tube adapter for the Hermle Z326-1220H 30 × 1.5/2.0 mL super-speed angle rotor, sold as a 6-pack. The host Z326-1220H rotor is among the highest-RCF rotors in the Hermle catalog (30,000 rpm / 65,395 × g at 6.5 cm radius), engineered for the Z36-HK / Z32-HK super-speed chassis family. The host rotor's 30 positions are dimensioned for standard 1.5/2.0 mL microtubes; this adapter converts a position to hold a 0.4 mL tube (ø 6 × 50 mm), letting the workflow run smaller-volume PCR-product or sub-microtube samples at the host rotor's super-speed RCF range.

Key Specifications

Compatibility & When to Order This SKU

Adapter pairing: Z326-1220H super-speed rotor only. Order this SKU when:

1. Adding 0.4 mL tube workflow capability to a Z326-1220H + super-speed chassis install, for PCR-product, sub-microvolume sample, or specialty 0.4 mL tube workflows at the rotor's high-RCF range.
2. Multiple packs for full-rotor 0.4 mL configuration: the Z326-1220H rotor has 30 positions; the 6-adapter pack covers a partial rotor configuration. For full-rotor 0.4 mL workflow, order 5 packs (30 adapters).
3. Mixed-format runs. When some positions hold standard 1.5/2.0 mL microtubes and others hold 0.4 mL tubes via this adapter (with adapter symmetry preserved across paired positions).
4. Replacement adapters if a current set is damaged or worn.

Why High-Speed Adapters Matter

The Z326-1220H rotor reaches 65,395 × g, substantially higher than standard microcentrifuge rotors (typically 15,000–22,000 × g). At this RCF range, tube fit precision matters: standard microtubes seat directly in the rotor below 16,000 × g, but at higher RCF the rotor's brochure notes adapters become necessary to maintain "full performance". The adapter ensures the tube remains seated and balanced at extreme inertial loads.

The Z36-HS adapter family was engineered specifically for this host rotor's super-speed RCF range:

Application Profile

High-RCF PCR-product cleanup in 0.4 mL tubes: when PCR-cleanup or post-amplification workflows use 0.4 mL tubes and the workflow benefits from the super-speed rotor's >50,000 × g range for tight pellet compaction.

Sub-microvolume sample prep at high RCF. Specialty workflows that work in 0.4 mL working volume and need high-RCF spin steps.

Cold-chain super-speed 0.4 mL workflows: refrigerated 0.4 mL tube prep on the Z36-HK / Z32-HK super-speed refrigerated chassis.

Specialty molecular-biology and clinical-research workflows. Protocols specifying 0.4 mL tube format that need high-RCF processing typically reserved for larger-volume tubes.

Z36-HK / Z32-HK super-speed chassis consolidation: labs operating super-speed microcentrifuge chassis benefit from the cross-tube-format adapter family covering 0.4, 0.5, and 1.5 mL formats on a single rotor.

Ordering & Configuration

Symmetric adapter loading. Pair adapter positions across the rotor by tube mass; all positions in a balanced pair must use matching adapter + tube combinations.

Adapter seat verification. At 30,000 rpm and 65,395 × g, balance precision is critical. Confirm each adapter is fully seated in its 1.5/2.0 mL position before loading the 0.4 mL tube. Per the brochure: adapters become necessary "for full performance" from 16,000 × g and above, running without correct adapter at high RCF risks tube damage and rotor imbalance.

Tube cap confirmation. All 0.4 mL tubes must be securely capped before spinning at 30,000 rpm, at super-speed RCF, partial cap seating risks sample loss.

Z36-04-HS ships as 6 adapters. 0.4 mL tubes (ø 6 × 50 mm) are operator-supplied (commodity sub-microvolume tube formats from major commercial suppliers).

Confirm at quote: host rotor (Z326-1220H in inventory), chassis pairing (Z36-HK, Z32-HK, Z327-HS, or -E variants), tube format (0.4 mL × ø 6 × 50 mm), pack count needed (1 pack for partial rotor; 5 packs for full 30-position 0.4 mL configuration), and lead time.

Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the adapters.

Z36-HS adapter family, for Z326-1220H super-speed angle rotor:

- Z36-04-HS (this product): 0.4 mL tubes (ø 6 × 50 mm)

- Z36-05-HS: 0.5 mL tubes (ø 8 × 32 mm)

- Z36-20-HS: 1.5 mL adapter for full performance at high RCF (necessary from 16,000 × g on)

Match the adapter to the workflow's tube format; the Z36-20-HS (1.5 mL) is necessary for standard 1.5/2.0 mL microtubes at the host rotor's high-RCF range.
