10–15 mL Round Insert for Z326-0685 85 mL Rotor (2/pk)

The Z326-85-A15R is the 10–15 mL round-bottom 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 × 10 mL or 15 mL round-bottom tube; the 6-position rotor takes 3 packs (6 inserts) for full symmetric loading, delivering 6 × 10–15 mL round-bottom tubes per cycle at the host rotor's high-RCF range. The R suffix in the SKU denotes round-bottom tube envelope (vs the conical envelope of the sister Z326-85-A15 insert) — the same insert serves both 10 mL Vacutainer-style and 15 mL round-bottom formats within the supported diameter and length envelope.

Key Specifications

Compatibility & When to Order This SKU

Insert pairing — Z326-0685 only. Order this SKU when:

1. Adding 10 mL or 15 mL round-bottom workflow capability to a Z326-0685 install — order 3 units for full 6-position symmetric loading (6 tubes/cycle).
2. High-RCF 10 mL Vacutainer or 15 mL round-bottom workflows — when the workflow needs the >10,000 × g range that the 85 mL host rotor delivers, on round-bottom tube formats.
3. Cold-chain mixed 10 mL Vacutainer / 15 mL round-bottom workflow — when both formats appear in the workflow and refrigeration is required.
4. Replacement inserts if a current set is damaged or worn.

Why a Single Insert Covers Both 10 mL and 15 mL

The A15R envelope (16–17 mm OD, 103–110 mm length range) spans both the standard 10 mL Vacutainer-style format (16 mm OD, ~107 mm length) and the 15 mL round-bottom format (17 mm OD, ~110 mm length). Both tube formats fit the same insert envelope without dimensional conflict — useful when a workflow batches mixed 10 mL and 15 mL round-bottom tubes in the same cycle (with mass balance preserved across paired positions).

Application Profile

High-RCF cold-chain 10 mL Vacutainer clinical-blood prep — clinical and clinical-research workflows handling 10 mL Vacutainer-style tubes that need high-RCF cold-chain processing on the 85 mL workflow rotor.

High-RCF 15 mL round-bottom prep — when 15 mL round-bottom tube workflow needs the >10,000 × g range that the host rotor delivers, on the cold-chain chassis.

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

Mixed 10 mL / 15 mL round-bottom workflow consolidation — when the workflow includes both formats on the same Z326-0685 chassis, the A15R envelope handles both within the same cycle.

Cross-format Z326-K / Z327-K core facilities — shared cores running both 85 mL bottle and 10–15 mL round-bottom workflows on the same chassis benefit from the insert approach.

Veterinary clinical workflows — small-animal blood-component separation in 10 mL or 15 mL round-bottom tube formats on the cold-chain high-RCF chassis.

Ordering & Configuration

6-position symmetric loading. All 6 positions must use matching A15R inserts for symmetric balance at 9,000 rpm.

Mixed-tube-format balance. When mixing 10 mL and 15 mL round-bottom tubes within the same cycle, pre-balance pairs by total tube + sample mass (10 mL filled to 10 mL is lighter than 15 mL filled to 15 mL).

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

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

Z326-85-A15R ships as 2 inserts. Tubes are operator-supplied (commodity 10 mL Vacutainer-style or 15 mL round-bottom formats).

Confirm at quote: host rotor (Z326-0685 in inventory), chassis pairing (Z326, Z326-K, Z327, Z327-K), tube format (10 mL Vacutainer-style or 15 mL round-bottom; 15 mL conical uses A15 instead), 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-A15R (this product) — 1 × 10–15 mL round-bottom

- Z326-85-A15 — 1 × 15 mL conical (different tube envelope)

- Z326-85-A30 — 1 × 30 mL round

- Z326-85-A50 / A50R / A50SS — 50 mL variants (conical, round, self-standing)

Match the insert to the workflow's tube envelope. The A15R's broad 10–15 mL envelope makes it the right pick when both 10 mL Vacutainer and 15 mL round-bottom formats appear in the workflow.
