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

The Z326-85-A50 is the 50 mL Falcon conical 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 × 50 mL conical tube; the 6-position rotor takes 3 packs (6 inserts) for full symmetric loading, delivering 6 × 50 mL conical tubes per cycle (300 mL total) at the host rotor's high-RCF range. The Z326-0685 + A50 insert combination delivers high-RCF 50 mL conical workflow (10,413 × g) — substantially higher RCF than dedicated 50 mL angle rotors on smaller chassis (e.g., Z326-1050 conical at 8,141 × g, Z206-0650 at 4,427 × g).

Key Specifications

Compatibility & When to Order This SKU

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

1. Adding 50 mL conical workflow to a Z326-0685 install — order 3 units for full 6-position symmetric loading (300 mL total per cycle).
2. High-RCF cold-chain 50 mL conical prep — when the workflow needs the >10,000 × g range for 50 mL conical tubes at refrigerated temperature (1 °C at max speed).
3. Mixed 85 / 50 mL workflow consolidation — when the chassis primarily runs 85 mL bottles but occasional 50 mL conical workflows arise.
4. Replacement inserts if a current set is damaged or worn.

Why High-RCF 50 mL Conical Matters

The Z326-85-A50 + Z326-0685 + Z326-K / Z327-K refrigerated chassis combination delivers a configuration not common in the broader centrifuge market: 50 mL conical workflow at >10,000 × g with 1 °C cold-chain integrity. Most dedicated 50 mL angle rotors top out at 4,000–8,000 × g; the 85 mL host rotor's higher max speed pushes 50 mL workflow into the high-RCF range typically reserved for smaller-volume tubes.

This matters when:

• Cell-pellet recovery in 50 mL conical needs tight pellet compaction at high RCF
• Density-gradient prep in 50 mL conical needs >10,000 × g for clean phase separation
• Cold-chain preserves protein integrity, gradient stability, or temperature-sensitive analytes through a high-force spin step

Application Profile

High-RCF cold-chain 50 mL cell-pellet recovery — pelleting cells from 50 mL suspension culture batches at high RCF and refrigerated temperature for downstream-stable preparation.

High-RCF 50 mL conical density-gradient prep — Ficoll, Percoll, sucrose-gradient prep at 6 × 50 mL parallel preps at >10,000 × g.

Cold-chain protein-prep workflows in 50 mL conical — TCA, ammonium-sulfate, organic-precipitation in 50 mL working volume at high RCF on the refrigerated chassis.

Clinical-research and biobank prep at 50 mL high-RCF cold-chain — patient sample fractionation, aliquot prep, freeze-storage workflows where the >10,000 × g range matters for the workflow output.

Mixed 85 / 50 mL workflow consolidation — when the lab's primary chassis is the Z326-0685 for 85 mL bottle workflows and 50 mL conical workflows are part of the protocol.

Cross-format Z326-K / Z327-K core facilities — shared cores running mixed bottle and tube workflows on the cold-chain high-RCF chassis.

Ordering & Configuration

6-position symmetric loading. All 6 positions must use matching A50 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 50 mL conical tube.

Tube cap confirmation. All 50 mL conical tubes must be securely capped before spinning at 9,000 rpm — at the host rotor's high RCF, cap integrity is critical.

Z326-85-A50 ships as 2 inserts. 50 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 (50 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 — 50 mL variants (Z326-0685 6 × 85 mL angle rotor):

- Z326-85-A50 (this product) — 50 mL Falcon conical

- Z326-85-A50R — 50 mL round-bottom

- Z326-85-A50SS — 50 mL self-standing conical (skirted base, no adapter support needed)

Match the insert to the 50 mL tube envelope: conical (A50), round-bottom (A50R), or self-standing skirted-base conical (A50SS).
