| Product Name | Disposable Inoculation Loops, 1 µL, Sterile, Calibrated |
| Catalog No. | IGM-HMM-0069 |
| Description | Sterile disposable polystyrene inoculation loops calibrated to 1 µL volume, color-coded blue for rapid identification. Designed for quantitative urine culture, bacterial colony picking, and microbiological streaking on agar plates. The calibrated loop design ensures consistent sample volume pickup, critical for quantitative microbiology and antimicrobial susceptibility testing. |
| Intended Use | Quantitative urine culture and colony counting; bacterial colony picking and isolation; streak plate inoculation; antimicrobial susceptibility testing; microbiological quality control testing; sample transfer in bacteriology workflows. |
| Principle / Technology | Calibrated loop design picks up and delivers 1 µL ± 5% of liquid sample; smooth, uniform loop interior minimizes sample retention; flexible polystyrene allows gentle streaking without agar gouging |
| Detection Method | Dip loop into liquid sample (urine, bacterial suspension); streak onto agar plate using standard quadrant streaking technique; incubate per microbiological protocol; count colonies and calculate CFU/mL = colonies × 1,000 (for 1 µL loop) |
| Components / Formulation | Blue color-coded disposable polystyrene inoculation loop (1 µL calibrated), individually wrapped or bulk packed; ethylene oxide (EtO) sterilized or gamma-sterilized |
| Storage Conditions | 15-30 °C in original packaging; protect from dust and moisture |
| Shelf Life | 36 months from manufacture date in unopened packaging |
| Package Specifications | 20 individually wrapped loops per peel-pack; 500 per case (25 packs); bulk non-sterile option available for non-critical applications |
| Product Form | Rigid blue polystyrene loop on 20 cm handle; 1 µL calibrated loop diameter ~2 mm |
| Key Features | Calibrated 1 µL volume (±5% tolerance); color-coded blue for easy identification; smooth loop surface for consistent sample pickup; flexible for gentle streaking; sterile (EtO or gamma, SAL 10⁻⁶); individually wrapped for aseptic technique; DNase/RNase-free; extended 20 cm handle for safe operation; lot traceability on packaging |
| Purity | Polystyrene meets USP Class VI; DNase/RNase-free certified; non-pyrogenic; no detectable metal contamination |
| 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 and moisture |
| Expiration Date / Stability | 36 months from sterilization date; do not use if package integrity is compromised; sterile loops intended for single use — do not resterilize |
| Regulatory / Compliance | CE marked; ISO 13485 manufactured; FDA registered; meets CLSI M40-A2 standards for microbiology specimen collection devices |
| Compatibility | Compatible with all standard agar plate media (blood agar, MacConkey, chocolate, Mueller-Hinton, Sabouraud, etc.); not recommended for viscous samples which exceed calibrated volume pickup; for liquid sample volumes >1 µL, 10 µL calibrated loops also available |
| 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.
