Microplate Carriers for Z446-750-AC (2/pk)

The Z446-750-MP is the dedicated microplate carrier for the Hermle Z446-750-AC swing-out rotor body — sold as a 2-pack. The complete Z446-750-AC rotor takes 4 carrier positions, so a full microplate configuration requires 2 units of Z446-750-MP (4 carriers total). Distinct from the Z446 family's round bucket (Z446-750-BUK) and rectangular bucket (Z446-MP-BUK) options, the Z446-750-MP is a purpose-built microplate carrier — the geometry is dedicated to standard-format plates rather than to bottles or inserts.

Key Specifications

Compatibility & When to Order This SKU

Carrier pairing — Z446-750-AC swing-out rotor body only. Order Z446-750-MP when at least one of the following applies:

1. Commissioning a Z446-750-AC for microplate workflows — order 2 units for the complete 4-carrier configuration.
2. Adding microplate capability to an existing Z446 / Z446-K install that currently runs round-bucket bottle workflows on the same Z446-750-AC rotor body — the same rotor body accepts the dedicated microplate carrier without requiring a rotor-body swap.
3. Replacement carriers if a current set is damaged or has reached service life.
4. Spare carrier inventory for facilities running mixed-format workflows that benefit from rotating carrier sets through cleaning cycles between sample types.

Carrier vs Bucket — Z446 Family Configuration Vocabulary

The Z446 swing-out rotor body (Z446-750-AC) supports three distinct attachment options. The terminology is precise because each option has different applications:

Choose Z446-750-MP for purpose-built microplate carrier geometry; choose Z446-MP-BUK if the lab's protocol or rotor inventory aligns with the rectangular-bucket approach.

Application Profile

ELISA and immunoassay wash spins — between wash steps, microplates spin briefly to drive wash buffer to the bottom of wells before aspiration; the dedicated carrier holds plates at the correct orientation.

Cell-culture plate workflows — pelleting non-adherent cells in 96-well or 24-well plates for media exchange or cell harvest.

Bead-based assay processing — magnetic-bead or affinity-bead assays in plate format that need brief centrifugation between binding steps.

Filter-plate workflows — vacuum-manifold-alternative spin-through plate processing, where the spin drives liquid through the filter membrane into a collection plate below.

High-throughput-screening plate prep — institutional HTS labs that run plate-format workflows at scale benefit from the Z446 family's higher capacity vs benchtop-only microplate centrifuges.

Loading & Balance

4-carrier symmetric loading. Pair opposite positions (1+3, 2+4) by total mass — plate + adapter + sample. Plate weights are highly consistent within format, but liquid volume per well affects total mass; balance pairs by volume distribution before each spin.

Plate stacking limits. The Z446-750-MP carrier accepts a single standard plate per position. For stacked-plate or deepwell configurations, confirm carrier dimensional clearance against the specific plate at order.

PCR-strip plate adapters. A separate stacking adapter SKU (Z446-MP-STK, sold separately) supports PCR-strip and stacking configurations on the same carrier — useful when the workflow mixes plate and PCR-strip formats.

Ordering & Configuration

Z446-750-MP ships as 2 microplate carriers. No rotor body, no plates, no PCR-strip adapter (Z446-MP-STK is sold separately).

Required for operation:

• Z446-750-AC swing-out rotor body (sold separately) or already in inventory
• For full 4-carrier configuration: order 2 units of this SKU
• Optional: Z446-MP-STK for PCR-strip / stacking workflows

Confirm at quote: rotor-body pairing (existing Z446-750-AC inventory or new rotor-body order), carrier count needed (2 or 4), plate format (standard SBS confirmed; deepwell or unusual heights need pre-order confirmation), and lead time.

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

Z446-K microplate workflow procurement summary:

- Z446-750-AC (rotor body) + 2 × Z446-750-MP (4 carriers) = full microplate configuration on the swing-out rotor

- Add Z446-MP-STK if PCR-strip / stacking-plate workflows are part of the protocol

- Compare to Z446-MP-BUK (rectangular microplate bucket) for the alternative bucket-style microplate path
