The Z600-S3-F30u is the 30 micron pore-size filter material for the Hermle SIEVA-3 filtration centrifuge family — PP DWL (polypropylene double-woven) construction, supplied as a pack of 10 filters. The 30 µm pore is the mid-coarse spec in the SIEVA-3 filter catalog (which spans 7 µ / 20 µ / 30 µ / 50 µ); it's the right pick for larger-particle workflows (crystallizates in the 50–200 µm range, biomass dewatering, larger-particle slurries) where the 7 µm or 20 µm fine pores would slow filtration without yield benefit.

Compatibility & Pore-Size Selection
SIEVA-3 family only. Pairs with the perforated centrifugal basket (Z600-500-P or Z600-S3-PC) inside a SIEVA-3 chassis.
Pore-size family positioning:
| Pore | SKU | Application class |
| 7 µm | Z600-S3-F7u | Finest — fine pharmaceutical crystallizates |
| 20 µm | Z600-S3-F20u | Mid-fine — intermediate crystallizates |
| 30 µm | Z600-S3-F30u (this product) | Mid-coarse — larger crystallizates, biomass dewatering |
| 50 µm | Z600-S3-F50u | Coarsest — large-particle slurries, brewing, food |
Filtration-time vs retention trade-off. The 30 µm pore filters faster than 20 µm or 7 µm by 1.5–3× depending on cake-formation characteristics, while still retaining particles ≥30 µm reliably. For workflows where the product-particle size is in the 50–200 µm range, the 30 µm pore is the throughput-optimized pick.
Application Profile
Larger pharmaceutical crystallizate isolation. Synthesis-end crystallizate crops in the 50–200 µm range — typical for many pharmaceutical and fine-chemical workflows. The 30 µm pore retains the product particles with margin while filtering ~2× faster than 20 µm.
Biomass dewatering in fermentation and brewing workflows — yeast and bacterial biomass typically retain on 30 µm pores while filtering quickly enough to support production-scale throughput.
Mid-particle slurry recovery. Catalyst recovery from mid-particle catalyst suspensions (typical Pt/C catalyst loading is 30–80 µm), polymer-bead workflows, and similar mid-particle solid-liquid separation applications.
Pharmaceutical wash-cycle workflows. When the workflow involves multiple wash cycles where total cycle time matters (recrystallization, solvent exchange), the 30 µm pore supports faster wash turnover than fine-pore alternatives.
Food-science biomass workflows that need particle retention but tolerate some fine-particle pass-through.
Method-development characterization. When validating a new SIEVA-3 workflow, the 30 µm pore is often the "first try" pore for biomass and large-crystallizate work — operators then compare against finer (20 µm) or coarser (50 µm) alternatives.
Inventory & Workflow Notes
Single-use vs reuse. Same considerations as other SIEVA-3 filter pore sizes — single-use for pharmaceutical-grade workflows; cleaning-and-reuse possible for non-cGMP applications.
Pack consumption rate. At one filter per cycle and 10 cycles per day, a pack of 10 = one operating day. Production-scale workflows stock multiple packs.
Filter installation. Per the SIEVA-3 operator's manual installation procedure. Confirm filter integrity before installation.
Ordering & Configuration
Z600-S3-F30u ships as a pack of 10 filters. Filter material only — basket and SIEVA-3 chassis sold separately.
Confirm at quote: pack quantity per workflow throughput, pore-size validation packs if commissioning a new install, and lead time for restocking.
Warranty: Filter material is a consumable; quality is guaranteed against manufacturing defect at time of delivery.
Pore-size family selection: the 30 µm pore (this SKU) is the throughput-optimized pick for larger-particle workflows. For finer retention (intermediate crystallizates, fine APIs), step down to Z600-S3-F20u or Z600-S3-F7u. For coarser high-throughput biomass work, step up to Z600-S3-F50u. Match the pore to the smallest particle the workflow needs to retain.
