| Product Name | Microcentrifuge Tubes, 2.0 mL, Sterile |
| Catalog No. | IGM-HMM-0049 |
| Description | Sterile 2.0 mL microcentrifuge tubes with secure snap-cap closure and frosted marking area. Gamma-irradiated for direct use in cell culture, microbiology, and sterile sample preparation workflows. |
| Intended Use | Sterile containment of cell suspensions, bacterial cultures, sterile reagent aliquots, and clinical samples in molecular biology, microbiology, and cell biology laboratories. |
| Principle / Technology | Larger capacity conical tube with the same footprint as 1.5 mL tubes, increasing maximum sample volume while maintaining compatibility with standard microcentrifuge rotors. Gamma sterilization provides validated SAL 10^-6 sterility assurance. |
| Detection Method | Sterility to USP <71>/ISO 11137; centrifugation to 21,000 x g; cap seal at 95 C for 10 minutes with dye solution |
| Sample Type | Sterile cell suspensions, bacterial inocula, filtered reagents, clinical specimens, protein purification fractions |
| Performance Range / Specifications | Working volume 0.2-2.0 mL; maximum RCF 21,000 x g; graduation marks at 0.5, 1.0, 1.5, 2.0 mL; temperature range -80 C to 121 C (autoclavable) |
| Sensitivity / LOD | Endotoxin <0.01 EU/mL; bioburden pre-sterilization <10 CFU/tube; nuclease free certified |
| Specificity | No extractable PCR inhibitors; no heavy metal leachables above USP limits; no cytotoxic leachables (USP <87> negative) |
| Reaction Conditions / Protocol | Open sterile packaging; remove tube aseptically; close cap with audible click; tube may be opened and closed multiple times while maintaining sterility. |
| Components / Formulation | Medical-grade polypropylene (USP Class VI), gamma-sterilized, packages sealed in ISO Class 7 cleanroom |
| Storage Conditions | 15-30 C; sterile packs remain sterile while packaging integrity is maintained |
| Shelf Life | 60 months from sterilization date |
| Package Specifications | 500 tubes per sterile bag, 10 bags per case; individually wrapped tubes 100 per case |
| Product Form | 2.0 mL conical microcentrifuge tube, sterile, with attached snap-cap, clear natural color |
| Quality Control | Sterility per batch; bioburden monitoring; centrifugation integrity; cap seal at 95 C; nuclease and endotoxin batch release |
| Key Features | Sterile and ready-to-use; 2.0 mL capacity in standard microcentrifuge footprint; secure snap-cap; frosted writing panel; autoclavable; RNase/DNase-free |
| Purity | Sterile (SAL 10^-6); DNase/RNase-free certified; endotoxin <0.01 EU/mL; non-cytotoxic; pyrogen-free |
| Concentration | N/A |
| Activity / Unit Definition | N/A |
| Molecular Weight | N/A |
| Source / Origin | USP Class VI polypropylene; gamma sterilized at validated dose per ISO 11137; manufactured under ISO 13485 |
| pH Range / Optimal pH | Inert pH 1-14 for aqueous solutions; resistant to standard laboratory solvents including DMSO, ethanol, and acetonitrile |
| Shipping Conditions | Ambient temperature; sterile packaging double-bagged to maintain sterility assurance |
| Expiration Date / Stability | 5 years from sterilization date; sterility guaranteed while packaging seal intact |
| Regulatory / Compliance | ISO 13485:2016; CE marked; ISO 11137 sterilization validation; USP <661> and <87> compliant; FDA registered |
| Compatibility | Fits all standard microcentrifuge rotors accepting 2.0 mL tubes; compatible with heating blocks, thermomixers, ice buckets, and tube racks; safe for storage at -80 C |
| Recommended Buffer System | Compatible with all standard buffers; resistant to guanidine-based lysis buffers, phenol-chloroform, and alcohol precipitation solutions |
| Application Notes / Precautions | Use aseptic technique when opening sterile packaging; if tube exterior contacts non-sterile surface, discard or disinfect before use in sterile applications; pre-label tubes before filling for efficient workflow |
| Batch-to-Batch Consistency | Tube dimension verified by automated optical comparator; gravimetric volume accuracy +/- 0.05 mL; sterility validation maintained per lot release documentation |
