| Product Name | Disposable Inoculation Loops, 10 uL, Sterile |
| Catalog No. | IGM-HMM-0061 |
| Description | Pre-sterilized disposable polystyrene inoculation loops calibrated to deliver 10 uL liquid volume. Smooth loop surface for consistent sample pickup and streak plating. Color-coded for volume identification. Individually wrapped for aseptic use. |
| Intended Use | Quantitative microbiological specimen inoculation, colony picking, streak plating onto agar media, and bacterial suspension transfer in clinical microbiology, food safety testing, and pharmaceutical quality control laboratories. |
| Principle / Technology | Precision-molded loop with calibrated internal diameter delivers approximately 10 uL of bacterial suspension. Smooth, burr-free loop surface prevents agar gouging during streak plating. Rigid polystyrene handle provides adequate length for safe Bunsen burner work when required. |
| Detection Method | Volume calibration by gravimetric water pickup (10 uL +/- 1 uL); sterility to ISO 11137; loop smoothness by microscopic surface inspection |
| Sample Type | Clinical urine specimens, bacterial colony suspensions, food and water samples, pharmaceutical product bioburden test samples, environmental monitoring swabs |
| Performance Range / Specifications | Calibrated volume 10 uL +/- 1 uL; handle length approximately 20 cm; loop internal diameter 4 mm; rigid polystyrene shaft |
| Sensitivity / LOD | Endotoxin <0.01 EU/loop; sterility assurance SAL 10^-6; no bacterial or fungal contamination after 14-day sterility test |
| Specificity | Non-bacteriostatic and non-fungistatic by USP <61>/<62> suitability testing; no inhibition of standard challenge microorganisms |
| Reaction Conditions / Protocol | Open individual peel pouch aseptically; dip loop into sample; transfer to agar plate; streak using standard quadrant or lawn technique; discard loop in biohazard waste. |
| Components / Formulation | Crystal polystyrene loop and handle, individually sealed in paper-plastic peel pouch, ethylene oxide or gamma sterilized, color-coded blue hub |
| Storage Conditions | 15-30 C; store in original packaging; protect from humidity |
| Shelf Life | 36 months from sterilization date |
| Package Specifications | 500 individually wrapped loops per box; 20 loops per tear-off strip; 2000 loops per case |
| Product Form | Individually wrapped sterile disposable inoculation loop, 10 uL calibrated, rigid handle |
| Quality Control | Volume calibration per lot; loop integrity 100% visual inspection; sterility per ISO 11137 batch release; bioburden pre-sterilization monitoring; loop surface DEFT microscopy |
| Key Features | Pre-sterilized and ready to use; calibrated 10 uL volume; individually wrapped for aseptic technique; smooth loop prevents agar damage; rigid handle for control; color-coded |
| Purity | Sterile (SAL 10^-6); non-cytotoxic; non-pyrogenic; DNase/RNase-free; endotoxin <0.01 EU/loop |
| Concentration | N/A |
| Activity / Unit Definition | N/A |
| Molecular Weight | N/A |
| Source / Origin | Medical-grade crystal polystyrene; injection molded in cleanroom under ISO 13485; sterilized by validated gamma irradiation |
| pH Range / Optimal pH | Polystyrene inert pH 2-10; suitable for contact with bacteriological media, saline, and buffer solutions |
| Shipping Conditions | Ambient; loops in peel pouches packed in partitioned boxes to prevent bending |
| Expiration Date / Stability | 3 years from sterilization; sterility maintained while individual peel pouch remains intact |
| Regulatory / Compliance | ISO 13485:2016; CE IVD marked; ISO 11137 sterilization; USP <61>/<62> and <71> compliant; FDA registered |
| Compatibility | Compatible with standard Petri dishes (90 mm, 100 mm, 150 mm), agar slants, and broth tubes; suitable for use with all common bacteriological culture media (blood agar, MacConkey, chocolate agar, etc.) |
| Recommended Buffer System | Compatible with sterile saline (0.85% NaCl), phosphate buffer, peptone water, and all standard microbiological diluents; loop material does not adsorb antimicrobial agents from specimens |
| Application Notes / Precautions | Use each loop only once; cool loop briefly after flame sterilization of tube/plate opening before sample pickup when working near open flame; hold loop handle near the hub end for optimal streak plate control; flexible loop material options available for tube inoculation applications |
| Batch-to-Batch Consistency | Loop internal diameter verified per mold cavity +/- 0.1 mm; volume calibration performed on statistical sample per ISO 2859-1 AQL 1.5; sterility batch release documentation accompanies each shipment |
