The BT1500-A1520 is a 20-position 1.5 / 2.0 mL microtube insert that drops into the Z326-02MP swing-out microplate bucket, converting a microplate-format swing-out position into a microtube batch position without a bucket or rotor swap. Cross-chassis applicability: the Z326-02MP microplate bucket is shared across multiple Hermle chassis families (Z327, Z446, Z366, Z32-HK, Z36-HK, Z307), so this insert serves any of those chassis when the workflow needs 20 × 1.5 / 2.0 mL throughput in a microplate-style swing-out position.

Compatibility & Configuration
Insert pairing: Z326-02MP microplate bucket only. This insert is engineered to seat into the Z326-02MP bucket envelope. Order this SKU when a Z326-02MP-equipped chassis needs to run 20 × 1.5 / 2.0 mL microtube batches alongside (or instead of) microplate workflows.
Cross-chassis insert: broad compatibility. Because the Z326-02MP bucket is part of multiple Hermle chassis accessory catalogs, this insert is usable on Z327, Z446, Z366, Z32-HK / Z36-HK family chassis (refrigerated and -HS super-speed variants), Z307, and corresponding -E voltage variants. Always confirm at order that the target chassis uses the Z326-02MP bucket geometry.
20 × 1.5 / 2.0 mL throughput per insert. Standard 1.5 / 2.0 mL microtubes (typical 11 mm OD) seat directly into the 20 dedicated insert positions. For full-bucket symmetric loading, both buckets in the swing-out rotor should carry matching inserts (40 microtubes per cycle in a 2-bucket rotor, more on multi-bucket rotors).
Application Profile
Microtube workflows on swing-out chassis. When the workflow benefits from swing-out geometry (flat sediment, easier supernatant aspiration) rather than a fixed-angle dedicated microtube rotor. Useful for protein precipitation, cell-pellet recovery, and density-gradient micro-prep.
Mid-RCF microtube batching. At 2,716 × g, suitable for cell pellet, organelle, and standard nucleic-acid prep that doesn't require the >15,000 × g range of dedicated high-speed microtube rotors.
Cross-chassis core-facility consolidation. Shared cores running mixed-chassis fleets (Z327 + Z446 + Z366 + Z32-HK etc.) can stock a single insert SKU that serves any chassis using the Z326-02MP bucket. Reduces accessory SKU sprawl in inventory.
Mixed-format workflow on a microplate-primary chassis. When the lab's chassis is configured primarily for microplate work but occasional 1.5 / 2.0 mL microtube workflows arise, this insert avoids the cost and inventory of a dedicated microtube rotor.
Ordering & Configuration
Symmetric loading. Both microplate buckets must carry matching configurations: both with this insert, or both with microplates / other inserts. Mixed-bucket configurations produce asymmetric balance.
Tube cap confirmation. All tubes must be capped before spinning at 4,500 rpm.
BT1500-A1520 ships as one or more inserts per pack: confirm pack quantity at quote.
Confirm at quote: chassis pairing (which chassis uses the Z326-02MP bucket in the target install), bucket inventory (Z326-02MP must be on hand or ordered separately), and insert count needed.
Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the inserts.
Z326-02MP bucket insert family:
- BT1500-A1520 (this product): 20 × 1.5 / 2.0 mL tube insert
- BT1500-A05: 20 × 0.5 mL tube insert (smaller microtube format)
- Z326-MPCA: 3 × chamber slide or 35/60 mm petri dish insert
Match the insert to the workflow's tube or sample format. The Z326-02MP bucket itself accepts microplates directly (2 plates per bucket) when no insert is installed.
