500 mL Centrifuge Bottles – 6,000 ×g, Sterilized, Non-Pyrogenic

500 mL Centrifuge Bottles – 6,000 ×g, Sterilized, Non-Pyrogenic Large-Volume Bioprocessing Flask for High-Throughput Cell Harvesting & Industrial Fermentation For laboratories scaling from benchtop to production, Hawach 500 mL centrifuge bottles close the gap between small-volume R&D and industrial bioprocessing. Manufactured from high-purity virgin polypropylene in ISO cleanroom environments, these bottles are designed for high-throughput cell harvesting, large-scale microbial precipitation, and upstream bioprocess sample concentration. Validated to 6,000 ×g under full rotor support, the 500 mL format fits standard large-volume centrifuge rotors from leading brands. Each bottle is factory sterilized and certified non-pyrogenic, ready for direct use in regulated biopharma workflows. Unlike smaller 250 mL bottles, the 500 mL version is optimized for: Batch volume parity with shake flasks and bioreactor harvests Reduced number of centrifuge runs per total sample volume Stackable storage and freezer organization Direct scaling from pilot to production without protocol changes Quick Technical Summary Item Specification SKU Number 11351002 Nominal Volume 500 mL Product Type Large-volume centrifuge flask / bottle Maximum Validated RCF 6,000 ×g Material High-purity virgin polypropylene Cap Type Leak-resistant screw cap Sterility Grade Factory sterilized (E-beam) Biological Grade Non-Pyrogenic Temperature Resistance -80°C to +121°C Packaging 2 pcs/bag, 20 bags/carton (40 pcs/carton total) Typical Applications Bulk cell harvesting, fermentation concentration, large-scale protein precipitation, bioprocess QC Decision Table – Problem – Solution – Outcome – Impact Problem Solution in Hawach 500 mL Bottle Outcome Impact Too many centrifuge runs per harvest batch 500 mL single-bottle capacity 2.5× fewer runs compared to 200 mL bottles High (time & energy saving at scale) Bottle deformation under full load at 6,000 ×g Reinforced wall geometry for 500 mL volume Stable structure, no bulging, consistent pellet formation High (reproducibility in production) Cross-batch pyrogen variability Non-pyrogenic grade with lot-specific testing Meets biopharma QC release criteria High (regulatory compliance) Bottles not stackable for freezer storage Uniform external geometry with flat top Stackable 3-4 high, saves freezer space Medium (laboratory organization) Scaling from R&D to production requires new validation Same material, same RCF rating as 250 mL version Direct scale-up – no revalidation needed High (seamless process transfer) Common Problems in High-Volume Bioprocessing Industrial and high-throughput labs face unique challenges when moving beyond 250 mL: Run count explosion -Processing a 10 L bioreactor harvest with 250 mL bottles requires 40 runs; with 500 mL bottles, only 20 runs. Pellet instability -Larger volume creates higher hydraulic pressure during deceleration, causing pellet resuspension if tube geometry is not optimized. Sterility breaches -More runs equal more cap handling, increasing contamination probability. Cold storage inefficiency -Non-stackable bottles waste valuable -80°C footprint. Scale-up friction -Different bottle dimensions or RCF ratings between R&D and production force protocol revalidation. Hawach 500 mL centrifuge bottles are engineered specifically to eliminate these scaling frictions.

A: The 500 mL bottle has a larger diameter and taller height, requiring specific 500 mL rotor buckets. It is not a scaled-up 250 mL shape but a separate industrial format. Q: Can I use this 500 mL bottle in a 250 mL rotor bucket? A: No. The dimensions are incompatible. Always use 500 mL-rated rotors. Q: Is the 500 mL bottle really validated to 6,000 ×g at full 500 mL fill? A: Yes, under standard conditions with supported rotor buckets. For fixed-angle rotors, we recommend ≤450 mL fill to account for meniscus effect. Q: Are these bottles RNase/DNase-free in addition to non-pyrogenic? A: Yes, each batch is tested for nuclease-free and endotoxin-free. COA available. Q: Can the bottles be centrifuged again after freezing? A: Yes, but inspect for cracks after thawing. Single freeze-thaw cycle is fine; repeated cycles may weaken polypropylene. Q: How do I properly seal the cap for high-speed runs? A: Screw until finger-tight, then an additional quarter-turn. Do not over-tighten (can crack threads). Procurement & Distributor FAQs (500 mL Bulk Focus) Q: What is the minimum order quantity for stock (non-custom) bottles? A: One carton (40 pieces). Smaller sample packs available upon request. Q: Do you offer mixed pallets (250 mL + 500 mL bottles)? A: Yes, for distributor orders. Contact for pallet configuration. Q: Can you supply bottles without sterilization (non-sterile) for in-house autoclaving? A: Yes, specify non-sterile when ordering. Lead time shorter (3-5 days). Q: Is there a bulk discount for annual volumes above 50,000 pieces? A: Yes, tiered pricing available. Request a volume quote. Q: Do you provide a certificate of irradiation for E-beam sterilization? A: Yes, included with each batch. Additional validation reports available upon request.
