| Specification | Variant A • 30 mL | Variant B • 100 mL | Variant C • 250 mL |
|---|---|---|---|
| Capacity (mL) | 30 | 100 | 250 |
| Material | Borosilicate glass (high chemical resistance) | Soda‑lime glass (common container glass) | HDPE (high‑density polyethylene) |
| Color / Finish | Amber (light‑attenuating finish) | Clear (transparent) | Natural translucent |
| Typical Height (mm) | ≈ 70 mm | ≈ 110 mm | ≈ 150 mm |
| Maximum Diameter (mm) | ≈ 33 mm | ≈ 45 mm | ≈ 60 mm |
| Neck Finish / Thread | 20 mm standard thread (compatible with common 20 mm closures) | 24 mm standard thread | 28 mm standard thread |
| Common Closure Types | Dropper, Screw cap, Tamper band | Screw cap, Pump, Tamper band | Screw cap, Flip cap, Dispensing closures |
| Weight (typical, g) | ≈ 45 g | ≈ 150 g | ≈ 80 g |
| Wall Thickness (mm) | ≈ 1.8 mm | ≈ 2.2 mm | ≈ 2.0 mm |
| Volume Accuracy | ±1.5% | ±1.0% | ±2.0% |
| Manufacturing Tolerance | ±0.5 mm | ±0.6 mm | ±1.0 mm |
| Thermal Resistance | Compatible with autoclave; stable to ≥121°C (short cycles) | Resistant to moderate heat; autoclave compatibility limited—recommend chemical sterilization for repeated cycles | Service range approx. −40°C to +80°C; not autoclave compatible |
| Barrier Performance (Qualitative) | Excellent inorganic barrier; negligible gas/vapor permeation | Excellent barrier for most liquids; impermeable to liquids and most gases | Moderate barrier; higher permeability to gases vs. glass—best for short to medium term storage |
| UV Protection | Amber finish—reduces UV transmission to <10% in 300–400 nm band | No inherent UV protection (UVT >90%); add-on sleeves recommended for light‑sensitive products | Optional UV inhibitors available in material formulations |
| Sterilization Compatibility | Autoclave, dry heat, chemical sterilants (EtOH, H2O2) | Chemical sterilants recommended; limited autoclave use | Gamma, EtO compatible; avoid steam autoclave |
| Recyclability / End‑of‑life | Highly recyclable (glass stream); inert to many recycling processes | Highly recyclable (glass stream) | Widely recyclable where HDPE is accepted (recycling code 2) |
| Typical Applications | Essential oils, pharmaceutical samples, laboratory reagents | Cosmetic serums, flavorings, small liquid formulations | Personal care, household chemicals, bulk dispensing |
| Regulatory / Compliance Notes | Glass types commonly used for food and pharmaceutical contact; inert and non‑reactive | Suitable for many consumer and cosmetic contact uses; follow application‑specific testing | HDPE widely used for consumer products; verify additive content for sensitive formulations |
