| Product Name | Filter Pipette Tips, 1000 uL, Sterile |
| Catalog No. | IGM-HMM-0039 |
| Description | Large-volume aerosol barrier tips with integrated hydrophobic filter for contamination-free transfer of 100-1000 uL volumes. Designed for cell culture manipulations, bulk reagent preparation, and high-volume PCR master mix dispensing. |
| Intended Use | Protected pipetting of cell suspensions, culture media, large-volume reagent aliquots, and infectious or biohazard samples requiring both operator and instrument protection from aerosol contamination. |
| Principle / Technology | Extended-length tip body with proximal sintered polyethylene aerosol barrier. The filter plug is positioned to maximize tip working volume while providing effective aerosol and splash protection for pipette internal components. |
| Detection Method | Filter integrity by differential pressure test; sterility validation per ISO 11137; nuclease panel each lot |
| Sample Type | Mammalian cell suspensions, bacterial cultures, concentrated buffers, tissue homogenates, blood fractions, clinical chemistry reagents |
| Performance Range / Specifications | Volume accuracy +/- 1.0% at 1000 uL, +/- 2.5% at 100 uL; aerosol barrier retention >99.9% |
| Sensitivity / LOD | DNase <0.05 pg/uL; RNase <0.005 ng/mL; endotoxin <0.005 EU/uL (LAL chromogenic method) |
| Specificity | No interference with common cell culture media components, antibiotics, or detection antibodies |
| Reaction Conditions / Protocol | Attach securely; use slow, controlled plunger movement for reproducible delivery of viscous samples; pre-wet for serum-containing solutions. |
| Components / Formulation | Translucent virgin polypropylene body, UHMW-PE aerosol barrier plug, silicone-free manufacturing process |
| Storage Conditions | 15-30 C; store racks upright; avoid exposure to direct sunlight or UV sterilization lamps |
| Shelf Life | 60 months from sterilization date |
| Package Specifications | 100 tips per hinged rack, 5 racks per case; refill tower system with 100 tips per tower |
| Product Form | Sterile racked tips with integrated aerosol barrier, individually sealed per rack |
| Quality Control | Rack-level sterility confirmation; filter position verified by automated vision system; endotoxin release per Ph.Eur. 2.6.14; migration testing for leachables |
| Key Features | Aerosol barrier for pipette and sample protection; extended length design; nuclease and endotoxin certified; color-coded blue for 1000 uL identification |
| Purity | Sterile, SAL 10^-6; certified nuclease-free, endotoxin-free, human DNA-free; heavy metals within USP limits |
| Concentration | N/A |
| Activity / Unit Definition | N/A |
| Molecular Weight | N/A |
| Source / Origin | Medical-grade polypropylene per USP <661.1>; manufactured in certified cleanroom under ISO 13485 |
| pH Range / Optimal pH | Compatible with solutions pH 1-14; no pH shift detected after 24-hour extraction test |
| Shipping Conditions | Ambient; protect rack packages from impact and moisture during transit |
| Expiration Date / Stability | 5 years from sterilization; filter integrity maintained throughout product shelf life |
| Regulatory / Compliance | CE marked for IVD use; ISO 13485:2016; ISO 14644 cleanroom classification; GMP compliant manufacturing |
| Compatibility | Universal fit for 1000 uL single-channel pipettors; compatible with liquid handling robots via SBS-format rack adapters |
| Recommended Buffer System | Compatible with all standard biochemistry, cell culture, and molecular biology buffer formulations |
| Application Notes / Precautions | For biohazard samples, use filter tips in conjunction with appropriate biosafety cabinet; change tips between samples and after any filter contact with liquid; not intended for reuse |
| Batch-to-Batch Consistency | Tip geometry verified by laser micrometer per mold cavity; filter pore size distribution measured by mercury porosimetry per batch; annual ISO 8655 external calibration |
