The Z600-S3 SIEVA-3 is a filtration centrifuge — a different class of instrument from the universal and microcentrifuge SKUs in the Hermle Z-series. Instead of separating by density (pelleting + supernatant), the SIEVA-3 spins a perforated or non-perforated basket lined with filter material, and the centrifugal force drives the liquid phase through the filter while retaining the solid phase inside the basket. This is the spec for sample-prep workflows that need solid-liquid separation by physical retention rather than density: crystallizate isolation, pharmaceutical intermediate purification, slurry dewatering, fine-particulate retention, and any workflow that conventionally uses Buchner-funnel filtration but at production-relevant volume.
Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

Application Profile
Pharmaceutical and fine-chemical crystallizate isolation. When a synthesis or formulation step yields a solid-phase product in mother liquor, the SIEVA-3 separates the crystallizate from the liquid by retaining solids in the basket. Pore size selection (7 µ to 50 µ) governs which particle classes are retained.
Slurry dewatering. Fine particulate slurries (catalyst recovery, mineral processing intermediates, polymer-bead workflows) drive their liquid phase through the basket filter while the solid phase concentrates inside the basket, recoverable as a damp cake.
API (active pharmaceutical ingredient) wash and recovery. Production-scale API workflows that conventionally use Buchner funnels can move to a SIEVA-3 for higher throughput and more uniform wash integrity — the rotating basket exposes the cake to wash solvent uniformly under centrifugal force.
Brewing, fermentation, and food-science applications. Yeast and biomass dewatering, juice and beverage clarification, and slurry-format intermediates in food processing benefit from the basket geometry and filter-pore selection.
Environmental sample retention. Fine-particulate water-quality samples and microplastic recovery workflows where particles need to be physically retained on a defined-pore-size filter rather than pelleted.
Design Architecture
Maintenance-free induction drive. No brush wear; the SIEVA-3 is engineered for institutional duty in process-laboratory and pilot-line environments.
Microprocessor-controlled speed regulation with 10-rpm pre-selection increments from 200 to 10,000 rpm. Running-time pre-selection in 10-sec increments up to 99 h 59 min, plus continuous mode for unattended overnight separations.
Imbalance switch-off. Asymmetric loading or mid-spin basket-load shift triggers automatic shutdown — at this speed and with the inertia of a fully loaded basket plus filter cake, this is non-negotiable safety protection.
Automatic lid-lock with transparent lid for visual control. The lid cannot unlock during a run, and the operator can visually monitor the separation (e.g., watch the liquid-phase clearance, observe cake formation) without opening the chamber.
Stainless-steel chamber and housing. Chemical-resistant for the solvent and reagent compatibility that pharmaceutical and fine-chemical workflows demand.
Quick-key for short runs. Brief separations (e.g., quick wash steps, sample-clarity checks) execute via a single button without programming a full timed cycle.
External temperature equalization (TC variants). The Z600-S3-TC variants add a connection for external temperature-control circulation — chilled or heated fluid loops to the chamber jacket, allowing the SIEVA-3 to operate at controlled temperature for thermolabile crystallizates or temperature-dependent separation kinetics. (See Z600-S3-TC product page for the temperature-controlled specification.)
SafeCoat 778 special coating (optional accessories). Additional chemical-resistance coating for aggressive solvent compatibility — available on the Z600-S3-PC perforated basket and Z600-S3-SC variant.
Frequently Asked Questions
What is the maximum speed and RCF of the Z600-S3? The SIEVA-3 reaches 10,000 rpm / 7,825 × g.
What basket and filter options does the SIEVA-3 use? A 500 mL perforated or non-perforated basket lined with PP DWL filter material, available in 7 µ, 20 µ, 30 µ, or 50 µ pore sizes.
Is the Z600-S3 a pelleting (density) centrifuge? No — it separates solids from liquid by physical retention on a filter, not by density gradient or pelleting. For density-based separation use a universal centrifuge such as the Z327 or Z446.
Can the Z600-S3 run at a controlled temperature? The base Z600-S3 is not temperature-controlled; the Z600-S3-TC variant adds an external temperature-equalization connection for chilled or heated separations.
What voltage does the Z600-S3 require? 120 V / 50–60 Hz standard; a 230 V / 50–60 Hz model is available by special order.
Ordering & Configuration
Ships configured per quote. The Z600-S3 body ships with operator's manual and power cord. Basket and filter material are ordered as configuration line items per workflow:
- Z600-500-P — 500 mL perforated centrifugal basket (drives liquid through the filter)
- Z600-500-NP — 500 mL non-perforated basket (retains both phases for collected-volume separations)
- Z600-S3-PC — perforated basket with SafeCoat 778 special coating for chemical resistance
- Filter material: Z600-S3-F7u (7 µ pore) / -F20u (20 µ) / -F30u (30 µ) / -F50u (50 µ) — supplied in package units of 10 filters
- Z600-S3-USB — USB data-package option
- Z600-S3-TC — temperature-controlled chassis for thermolabile separations (separate SKU)
Voltage variants: The 230 V / 50–60 Hz model is available by special order. For external temperature control, see Z600-S3-TC (120 V), with a 230 V version available by special order.
Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain). Service network covers basket validation, drive maintenance, and filter-fit verification.
This is a process-instrument purchase rather than an off-the-shelf bench centrifuge. Use the quote request to specify: workflow (what's being separated, target pore size, batch volume, solvent compatibility), basket configuration (perforated vs non-perforated, standard vs SafeCoat), filter pore-size pack quantities, voltage, and whether external temperature equalization is required (drives selection between Z600-S3 and Z600-S3-TC). Pre-installation consultation typical for first-time filtration-centrifuge installs.
Filtration centrifuge selection note: if your workflow is density-based separation (sediment vs supernatant, pellet recovery from suspension), a universal centrifuge such as the Z327 or Z446 is the right tool. The SIEVA-3 is specifically for solid-phase retention via filter — different physics, different output. Confirm separation mode before specifying.
