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.
