2 × 30 mL Adapter for Z366-06250 250 mL Angle Rotor (2/pk)

The Z366-06250-A30 is a 2-position 30 mL tube adapter for the Hermle Z366-06250 6 × 250 mL angle rotor on the Z366 / Z366-K chassis — sold as a 2-pack. Each adapter holds 2 × 30 mL tubes; the 6-position rotor takes 3 packs (6 adapters) for full symmetric loading, delivering 12 × 30 mL tubes per cycle at the host rotor's high-RCF range (10,016 × g). The 30 mL format sits in the intermediate volume range — useful when the workflow specifies 30 mL working volume and benefits from the 250 mL rotor's high-RCF range on the Z366-K refrigerated chassis.

Key Specifications

Compatibility & When to Order This SKU

Adapter pairing — Z366-06250 250 mL angle rotor only. Order this SKU when:

1. Adding 30 mL tube workflow to a Z366-06250 install — order 3 units for full 6-position symmetric loading (12 tubes/cycle).
2. High-RCF cold-chain 30 mL prep — when 30 mL workflow needs the >10,000 × g range with cold-chain integrity (3 °C at max speed).
3. Bioprocess intermediate prep at 30 mL — vaccine-development and bioprocess workflows that batch 30 mL tubes for intermediate concentration steps at high RCF.
4. Replacement adapters if a current set is damaged or worn.

Why 30 mL on a 250 mL Rotor

The 30 mL tube format sits in an intermediate volume range — useful for bioprocess intermediates and clinical-research aliquot prep — but is uncommon as a primary workflow format. Most chassis don't have a dedicated 30 mL rotor. The Z366-06250-A30 adapter delivers 30 mL workflow on the 250 mL rotor with the high-RCF range preserved (10,016 × g vs the 4,000–8,000 × g typical on dedicated mid-volume rotors).

This matters when:

• The lab's primary chassis is the Z366-K and 30 mL is an occasional workflow
• The 30 mL workflow needs >5,000 × g for tight pellet recovery
• Bioprocess intermediate prep batches 30 mL aliquots between smaller and larger volumes

Application Profile

High-RCF cold-chain 30 mL bioprocess intermediate prep — vaccine-development and bioprocess workflows that batch 12 × 30 mL tubes per cycle at high RCF and refrigerated temperature.

High-RCF mid-volume cell harvest in 30 mL — when cell-culture workflows batch 30 mL suspension cultures requiring tight pellet compaction.

Cold-chain 30 mL protein-prep workflows — TCA, ammonium-sulfate, organic-precipitation in 30 mL working volume on the high-RCF refrigerated chassis.

Mixed-volume Z366-K workflow consolidation — when the lab's primary 250 mL workflow on the Z366-06250 rotor includes occasional 30 mL processing alongside other intermediate-volume formats.

Cross-format Z366-K core facilities — labs running mixed bottle and tube workflows on the same chassis benefit from the Z366-06250 adapter family.

Environmental and analytical sample prep at 30 mL — when sample-prep workflows need high-RCF processing in 30 mL tubes.

Ordering & Configuration

6-position symmetric loading. All 6 positions must use matching A30 adapters for symmetric balance at 8,000 rpm.

Per-adapter symmetric loading. Within each adapter, the 2 tubes should be paired by mass.

Adapter seat verification. Confirm each adapter is fully seated in its 250 mL position before loading the 30 mL tubes.

Tube cap confirmation. All 30 mL tubes must be securely capped before spinning at 8,000 rpm.

Z366-06250-A30 ships as 2 adapters. 30 mL tubes are operator-supplied (commodity 30 mL conical or round-bottom formats from major commercial suppliers).

Confirm at quote: host rotor (Z366-06250 in inventory), chassis pairing (Z366, Z366-K), tube format (30 mL conical or round, 26 mm OD), pack count (3 packs for full 6-position configuration = 12 tubes/cycle), and lead time.

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

Z366-06250 adapter family (6 × 250 mL angle rotor):

- Z366-06250-A30 (this product) — 2 × 30 mL (12/cycle)

- Z366-06250-A15 — 4 × 15 mL conical (24/cycle)

- Z366-06250-A50 — 1 × 50 mL conical (6/cycle)

- Z366-06250-A50R — 1 × 50 mL round (6/cycle)

- Z366-06250-A225C — 1 × 175/225 mL conical (6/cycle)

Pick the A30 when 30 mL is the workflow's intermediate working volume and the high-RCF range matters.
