15 mL Conical Insert for Z326-0685 85 mL Rotor (2/pk)

The Z326-85-A15 is the 15 mL conical tube insert for the Hermle Z326-0685 6 × 85 mL angle rotor on the Z326 / Z327 chassis family — sold as a 2-pack. Each insert holds 1 × 15 mL conical tube; the 6-position rotor takes 3 packs (6 inserts) for full symmetric loading, delivering 6 × 15 mL conical tubes per cycle at the host rotor's high-RCF range. The Z326-0685 is the 85 mL workflow rotor in the Z326 / Z327 family — at 9,000 rpm / 10,413 × g / 11.5 cm radius / 1 °C at max speed (refrigerated chassis), it serves bottle workflows; with this insert, it converts to 15 mL conical workflow on the same chassis.

Key Specifications

Compatibility & When to Order This SKU

Insert pairing — Z326-0685 only. The Z326-85-A15 is engineered for the Z326-0685 6 × 85 mL angle rotor. Order this SKU when:

1. Adding 15 mL conical workflow capability to a Z326-0685 install — order 3 units for full 6-position symmetric loading (6 tubes/cycle).
2. High-RCF 15 mL conical workflows — when 15 mL conical workflow needs the >10,000 × g range that the 85 mL host rotor delivers (substantially exceeds the 4,427 × g of the dedicated Z206-1215 12 × 15 mL workflow rotor on smaller-chassis configurations).
3. Cold-chain high-RCF 15 mL conical prep — when both refrigeration (1 °C at max speed) AND high RCF are required for the 15 mL workflow.
4. Replacement inserts if a current set is damaged or worn.

Why an 85 mL Rotor Becomes a 15 mL Rotor

The Z326-0685 6 × 85 mL angle rotor is engineered for 85 mL bottle workflows (vaccine intermediate prep, mid-volume cell harvest, mid-volume protein prep). When the workflow shifts to 15 mL conical, the chassis would normally need a rotor swap to a dedicated 15 mL rotor — except the Z326-85-A15 insert keeps the workflow on the same Z326-0685 rotor, with the higher-RCF range (10,413 × g) preserved for the smaller tubes.

This matters when:

• The lab's 85 mL workflow is primary but 15 mL conical is occasional
• The 15 mL workflow specifically needs >10,000 × g (vs the lower-RCF range of dedicated 15 mL rotors on smaller chassis)
• Rotor-swap downtime is a workflow constraint

Application Profile

High-RCF cold-chain 15 mL conical clinical-research prep — patient sample fractionation, density-gradient prep, biobank aliquot prep at 6 × 15 mL conical per cycle on the cold-chain high-RCF rotor.

High-RCF cell-pellet recovery in 15 mL conical — when the workflow needs tight pellet compaction at the 15 mL scale that the 10,413 × g range delivers.

Density-gradient prep in 15 mL at high RCF — Ficoll, Percoll, sucrose-gradient workflows requiring >10,000 × g.

Mixed 85 / 15 mL workflow consolidation — when the lab's primary chassis is configured for 85 mL bottle workflows on the Z326-0685 rotor but occasional 15 mL conical workflows arise.

Cross-format Z326-K / Z327-K core facilities — shared cores running both 85 mL bottle and 15 mL conical workflows on the same chassis benefit from the insert approach for workflow-specific configuration.

Ordering & Configuration

6-position symmetric loading. All 6 positions must use matching A15 inserts for symmetric balance at 9,000 rpm.

Insert seat verification. Confirm each insert is fully seated in its 85 mL position before loading the 15 mL tube.

Tube cap confirmation. All 15 mL conical tubes must be securely capped before spinning at 9,000 rpm.

Z326-85-A15 ships as 2 inserts. 15 mL conical tubes are operator-supplied (commodity Falcon / Corning / equivalent formats).

Confirm at quote: host rotor (Z326-0685 in inventory), chassis pairing (Z326, Z326-K, Z327, Z327-K), tube format (15 mL conical Falcon-style), pack count (3 packs for full 6-position configuration), and lead time.

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

Z326-85 insert family (Z326-0685 6 × 85 mL angle rotor):

- Z326-85-A15 (this product) — 1 × 15 mL conical

- Z326-85-A15R — 1 × 10–15 mL round-bottom

- Z326-85-A30 — 1 × 30 mL round

- Z326-85-A50 — 1 × 50 mL conical

- Z326-85-A50R — 1 × 50 mL round

- Z326-85-A50SS — 1 × 50 mL self-standing conical

Match the insert to the workflow's tube format. The Z326-0685 rotor's high-RCF range is preserved across all insert configurations for high-force prep at smaller volumes.
