12 × 15 mL Conical Insert for Z496-1000-1L Buckets (2/pk)

The Z496-1L-A15 is a 12-position 15 mL conical tube insert for the Hermle Z496-1000-1L round buckets on the Z496-1000-AC 4-place swing-out rotor (Z496-K chassis), sold as a 2-pack. Each insert holds 12 × 15 mL conical tubes; the 4-bucket rotor configuration takes 2 packs (4 inserts) for full symmetric loading, delivering 48 × 15 mL conical tubes per cycle on the round-bucket platform. The Z496-1L-A* insert family fits the Z496-1000-1L round bucket geometry, distinct from the Z496-1000-A* / Z496-1000-RBUK family which fits the rectangular-bucket configuration on the same Z496-K chassis.

Key Specifications

Round Bucket vs Rectangular Bucket: Why Two Insert Families on the Same Chassis

The Z496-K chassis supports two bucket profiles on the Z496-1000-AC swing-out rotor body:

The round bucket reaches higher max RCF (5,203 × g vs 3,964 × g) due to the longer max radius (22 cm vs 20.1 cm). For high-RCF 15 mL conical workflows on the Z496-K, the Z496-1L-A15 (round-bucket insert) delivers higher RCF than the corresponding Z496-1000-A15-equivalent on the rectangular bucket would deliver. The trade-off: the rectangular bucket accepts microplates direct-fit; the round bucket does not.

Compatibility & When to Order This SKU

Insert pairing: Z496-1000-1L round bucket only. Order this SKU when:

1. Adding 15 mL conical workflow at high RCF to a Z496-K + Z496-1000-1L install. Order 2 units for full 4-bucket symmetric loading (48 tubes/cycle).
2. High-RCF cold-chain 15 mL conical clinical-research and biobank prep: when the workflow needs the round bucket's higher 5,203 × g range with cold-chain integrity (9 °C at max speed).
3. Mixed round-bucket Z496-K workflow consolidation: when the lab uses the round bucket for tube-format and bottle-format workflows alongside this 15 mL conical insert.
4. Replacement inserts if a current set is damaged or worn.

Application Profile

4-bucket symmetric loading. All 4 round buckets must use matching A15 inserts for symmetric balance.

Per-insert symmetric loading. Within each insert, the 12 conical tubes should be balanced symmetrically. Pair tubes by mass.

Design Architecture

High-RCF cold-chain 15 mL conical clinical-research and biobank prep at scale: patient sample fractionation, density-gradient prep, biobank aliquot prep at 48 × 15 mL conical per cycle on the round-bucket cold-chain swing-out chassis.

Cell-culture pellet recovery in 15 mL at high RCF, pelleting non-adherent cells from 48 parallel 15 mL suspension batches per cycle with the round bucket's higher 5,203 × g range.

High-RCF density-gradient prep in 15 mL: Ficoll, Percoll, sucrose-gradient prep at 48 parallel preps per cycle on the cold-chain round-bucket swing-out chassis where the higher RCF supports faster phase separation.

Cold-chain protein prep in 15 mL conical at high RCF: TCA, ammonium-sulfate, organic-precipitation in 15 mL working volume at 48 parallel preps with refrigeration on the round-bucket platform.

Mixed-format Z496-K core facilities: labs running 15 mL conical alongside other Z496-1L-A* insert formats (A250F, A500S) on the same round-bucket inventory benefit from the cross-format insert family.

Ordering & Configuration

4-bucket symmetric loading. All 4 round buckets must use matching A15 inserts. Mixed-bucket configurations produce mass asymmetry.

Tube cap confirmation. All conical tubes must be securely capped before spinning at 4,600 rpm.

Z496-1L-A15 ships as 2 inserts. 15 mL conical tubes are operator-supplied (commodity Falcon / Corning / equivalent formats). The Z496-1000-1L round buckets are sold separately.

Confirm at quote: bucket pairing (Z496-1000-1L round buckets in inventory; distinct from the Z496-1000-RBUK rectangular bucket which uses Z496-1000-A* inserts), chassis pairing (Z496-K or Z496-K-UC), tube format (15 mL conical Falcon-style), pack count (2 packs for full 4-bucket configuration = 48 tubes/cycle), and lead time.

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

Z496-1L round-bucket insert family (Z496-1000-1L on Z496-K chassis):

- Z496-1L-A15 (this product): 12 × 15 mL conical (48/cycle, high-RCF round bucket)

- Z496-1L-A250F: 250 mL conical bottle insert

- Z496-1L-A500S: 500 mL flat bottle (69.5 mm dia) insert

The Z496-1L family delivers higher RCF (5,203 × g) than the Z496-1000-RBUK rectangular-bucket family (3,964 × g) at the cost of microplate-direct compatibility.
