The Z496-1000-MPRA is a bench ergonomics handling tool that assists in lifting microplate stacks out of the Hermle Z496-1000-RBUK rectangular bucket on the Z496-K chassis 4-place swing-out rotor. The Z496-K's institutional throughput configurations (the Z496-1000-RBUK rectangular bucket accepts microplates direct-fit and supports stacking via plate-stacking adapters) can produce loaded bucket weights that make manual microplate-stack lifting from inside the rotor chamber awkward — the Z496-1000-MPRA tool engages the plate stack and supports the lift. Distinct from the Z446-MP-RA (the corresponding tool for the Z446-K chassis Z446-MP-BUK rectangular bucket) — the chassis-specific tools are not interchangeable.

What This Tool Does
The Z496-1000-MPRA is a bench ergonomics tool, not a centrifuge component. Its function in the workflow:
- Engagement — the tool engages the microplate stack from above
- Lift assistance — supports the loaded plate-stack weight during the lift from the deep Z496-K rotor chamber to the bench
- Bench placement — provides a secure handhold for placing the loaded plate stack on the bench for unloading
- Repeated-cycle ergonomics — for HTS, large-cohort clinical-research, and multi-plate ELISA workflows running many cycles per day, the tool reduces operator hand and wrist strain
Why a Microplate Removing Aid Matters on Z496-K
The Z496-K chassis is one of Hermle's larger floor-standing platforms with a deeper rotor chamber than typical bench centrifuges. When the Z496-1000-RBUK rectangular bucket is loaded with multiple microplates (with stacking adapters delivering 3–6 plates per bucket position depending on plate height), the total loaded mass per bucket can be substantial. Manual lifting from the deep rotor chamber requires reaching down and pulling up — an awkward biomechanical motion at the cumulative scale of high-throughput workflows.
The Z496-1000-MPRA addresses three specific workflow pain points:
- Operator hand and back strain in HTS and large-cohort labs running many cycles per day on the Z496-K floor-standing chassis
- Drop risk when lifting heavy plate stacks from a deep rotor chamber
- Cross-contamination risk when the operator touches plate exterior surfaces during awkward lifts
For institutional clinical-research, biobank intake, and HTS workflows where the Z496-1000-RBUK is in routine high-cycle use, the removing aid is a worthwhile workflow accessory.
Application Profile
HTS plate-prep workflows on Z496-K — institutional HTS labs that batch many microplates per cycle on the Z496-K floor-standing platform.
Multi-plate ELISA / immunoassay wash-spin workflows at scale — clinical-research and diagnostic ELISA processing where the wash step batches multiple plates per bucket per cycle.
Large-cohort clinical-research plate-format prep — patient sample plate prep workflows that batch many plates per cycle on the Z496-K platform.
Cell-culture plate workflows at institutional scale — when cell-culture plate processing batches multiple plates per bucket per cycle.
Cold-chain plate-format workflows — refrigerated plate-format workflows on the Z496-K cold-chain swing-out chassis where the workflow's repeated-cycle handling justifies the bench-ergonomics improvement.
Educational and teaching labs — teaching workflows where students learn to handle loaded plate stacks safely benefit from the ergonomic aid.
Ordering & Configuration
Bench accessory — not a centrifuge component. The Z496-1000-MPRA is used at the bench during plate-stack unload, not inside the rotor during spin operation.
Bucket-specific compatibility. The Z496-1000-MPRA is engineered specifically for the Z496-1000-RBUK rectangular bucket geometry on the Z496-K chassis. It does not engage the Z446-MP-BUK (Z446-K chassis) — which has its own Z446-MP-RA removing-aid SKU.
Z496-1000-MPRA ships as each. Useful pack quantity for facilities running a single Z496-K chassis or for spare-tool inventory.
Confirm at quote: bucket pairing (Z496-1000-RBUK in inventory), chassis pairing (Z496-K or Z496-K-UC), workflow context (HTS, multi-plate ELISA, large-cohort clinical-research benefit most), quantity (each per SKU; multiple for facilities with multiple chassis), and lead time.
Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the removing-aid units.
Z496-1000-RBUK rectangular-bucket workflow accessory family:
- Z496-1000-MPRA (this product) — Microplate removing aid for ergonomic bucket handling
- Z496-1000-RBUK — rectangular bucket (sold separately)
- Z496-1000-A* inserts for tube/bottle-format workflows on the bucket
The Z496-1000-MPRA is the ergonomic-aid SKU for plate-format workflows on the Z496-K — pick when the workflow's repeated-cycle handling justifies the bench-ergonomics improvement.
