| Product Name | Disposable Serological Pipette, 25 mL, Sterile, Individually Wrapped |
| Catalog No. | IGM-HMM-0067 |
| Description | Sterile disposable polystyrene serological pipette, 25 mL capacity, with negative graduations, color-coded with filter plug, individually wrapped in peel-open paper-plastic packaging. Designed for accurate liquid handling in cell culture, media preparation, and general laboratory applications. The fiber filter plug prevents liquid and aerosol contamination of pipetting devices. |
| Intended Use | Accurate aspiration and dispensing of liquids in cell culture, bacteriology, and general laboratory workflows; media and buffer transfer; sample aliquoting; serial dilution preparation. |
| Principle / Technology | Gravimetrically calibrated to Class B accuracy (±2% at full volume); reverse graduations allow delivery of total volume plus excess; color-coded for rapid volume identification |
| Sample Type | Compatible with aqueous solutions, cell culture media, buffers, dilute acids and bases, and most organic solvents except strong oxidizing agents and aromatic hydrocarbons |
| Components / Formulation | Polystyrene tube with negative graduations (0.5 mL increments for 25 mL), hydrophobic polyethylene fiber filter plug, paper-plastic peel pouch (gamma-irradiated) |
| Storage Conditions | 15-30 °C in original packaging; protect from direct sunlight and excessive humidity; store flat to prevent warping |
| Shelf Life | 60 months from manufacture date in unopened packaging |
| Package Specifications | 25 individually wrapped pipettes per bag; 200 per case (8 bags × 25); also available in bulk pack (non-individually wrapped, 50 per bag) |
| Product Form | Rigid sterile polystyrene pipette, individually wrapped; transparent with color-coded markings |
| Key Features | Gamma-sterilized (SAL 10⁻⁶); individually wrapped for aseptic technique; fiber filter plug; color-coded for volume identification; negative graduations; RNase/DNase-free; non-pyrogenic (endotoxin <0.5 EU/device); smooth tip orifice for consistent drop delivery; calibrated TD (to deliver) |
| Purity | Polystyrene meets USP Class VI biocompatibility; RNase/DNase tested free per lot; pyrogen tested (<0.5 EU/device by LAL) |
| Concentration | Not applicable — solid consumable product |
| Activity / Unit Definition | Performance verified per dimensional and functional specifications |
| Molecular Weight | Not applicable — polymer/glass consumable product |
| Source / Origin | Virgin polypropylene, polystyrene, borosilicate glass as specified |
| pH Range / Optimal pH | Not applicable — solid consumable |
| Shipping Conditions | Ambient; protect from crushing; store away from strong odors which may be absorbed |
| Expiration Date / Stability | 60 months (5 years) from sterilization date when package integrity is maintained; do not use if package is opened or damaged; sterilized by gamma irradiation — no EtO residues |
| Regulatory / Compliance | CE marked (Class I medical device); FDA 510(k) registered; ISO 13485 manufactured; USP Class VI; meets ISO 12771 standards for disposable serological pipettes |
| Compatibility | Compatible with standard pipette controllers (Drummond, BrandTech, Eppendorf) and manual pipette bulbs; liquid temperature range 4-50 °C; not compatible with strong oxidizing acids (nitric, sulfuric >50%), aromatic hydrocarbons (benzene, toluene), or chlorinated solvents (chloroform, dichloromethane) — use glass pipettes for these solvents |
| Recommended Buffer System | Not applicable — use with standard aqueous buffers and organic solvents per chemical compatibility |
| Application Notes / Precautions | Single use only for sterile products; inspect packaging integrity before use; dispose per biohazard guidelines |
| Batch-to-Batch Consistency | Dimensional tolerance within specification; functional testing per AQL sampling plan |
For research use only, not for clinical use.
