| Product Name | Amber Glass Reagent Bottles, Narrow Mouth, PTFE-Lined Screw Cap, 100/250/500/1000 mL Set |
| Catalog No. | IGM-HMM-0074 |
| Description | Assorted amber (actinic) borosilicate glass reagent bottles with narrow mouth and PTFE-lined polypropylene screw caps for light-sensitive chemical and reagent storage. Amber glass blocks ultraviolet (UV) light below ~500 nm while allowing visual inspection of contents through the brown-tinted glass, protecting light-sensitive reagents (fluorescent dyes, vitamins, antibiotics, photosensitive catalysts, enzymatic substrates) from photodegradation. The borosilicate glass (Type I, USP Class A) offers excellent chemical resistance, low thermal expansion, and minimal extractables, making it suitable for storing acids, bases, organic solvents, and high-purity reagents. Bottles are supplied in a graduated assorted set of four sizes (100 mL, 250 mL, 500 mL, 1,000 mL) with corresponding PTFE-faced polypropylene caps that provide a chemically resistant, leak-proof seal. |
| Intended Use | Storage of: light-sensitive biochemical reagents and standards; HPLC and LC-MS mobile phases and standard solutions; fluorophore and dye stock solutions; antibiotics and media supplements; photosensitive pharmaceutical and drug discovery compounds; enzymes and protein solutions; organic solvents; acids and bases; and any laboratory solution requiring protection from photodegradation. |
| Principle / Technology | Amber borosilicate glass contains metal oxide additives (iron, manganese, cobalt, and/or sulfur) that impart the characteristic brown-amber color and absorb UV and short-wavelength visible light (transmission <10% below 500 nm at 2 mm wall thickness). This UV filtration protects photosensitive compounds from photodegradation, photooxidation, and photoisomerization reactions catalyzed by UV and blue light. Borosilicate glass (SiO2-B2O3) provides low coefficient of thermal expansion (approximately 3.3 x 10^-6/C), good thermal shock resistance, and excellent chemical durability (Type I glass per USP <660>). |
| Detection Method | Bottles are ready-to-use; wash with appropriate solvent, acid/base, or detergent and rinse thoroughly with ultrapure water before first use; sterilize by autoclaving (cap must be loosened to prevent pressure buildup) or dry heat sterilization; for trace analysis, acid-wash with 10% HNO3 followed by thorough water rinsing. |
| Sample Type | Liquid reagents and solutions; solid reagents (powders, crystals, lyophilized materials); not for storage of hydrofluoric acid (etches glass) or strong alkaline solutions at elevated temperatures (>60 C) for extended periods (>24 h) which may etch glass. |
| Performance Range / Specifications | Glass type: Type I borosilicate (USP Class A); color: amber (UV-blocking, transmission <10% below 500 nm); capacity: 100 mL, 250 mL, 500 mL, 1,000 mL; mouth: narrow (approximately 18-30 mm ID depending on size); cap: polypropylene with PTFE-faced liner; graduation: molded or enamel, approximate; thermal shock resistance: delta T >100 C; autoclave safe: yes (121 C, 15 psi). |
| Sensitivity / LOD | Not applicable — laboratory glassware. |
| Specificity | Amber glass specifically blocks UV and short-wavelength visible light; PTFE liner provides chemically inert sealing surface compatible with most reagents. |
| Reaction Conditions / Protocol | Glass is chemically inert under standard storage conditions; PTFE is essentially chemically inert (attacked only by molten alkali metals, fluorine gas, and some fluorine compounds at elevated temperature and pressure). |
| Components / Formulation | Amber borosilicate glass bottles (4 bottles: 100 mL, 250 mL, 500 mL, 1,000 mL) with matching PTFE-lined polypropylene screw caps. |
| Storage Conditions | Store at RT (15-25 C); keep caps tightly closed when not in use; protect from physical impact (glass is breakable). |
| Shelf Life | Indefinite (glass is chemically stable); PTFE cap liner: 10 years recommended replacement. |
| Package Specifications | Assorted Set: 1 x 100 mL, 1 x 250 mL, 1 x 500 mL, 1 x 1,000 mL bottle with caps; or individual sizes in cases of 12. |
| Product Form | Amber borosilicate glass bottles with molded graduation marks; narrow mouth; PTFE-faced polypropylene screw cap. |
| Quality Control | Each lot: glass type (Type I USP, hydrolytic resistance per USP <660>); capacity within +/-5% of nominal; cap leak test (water-filled, inverted, 24 h, no leakage); cap torque test; annealed stress test (<30 nm/cm optical retardation); visual inspection (no cracks, chips, bubbles, or defects). |
| Key Features | Amber borosilicate glass for UV protection; Type I USP glass — low extractables; PTFE-lined caps for chemical compatibility; narrow mouth for controlled pouring; assorted set of 4 sizes; graduated for approximate volume measurement; autoclavable. |
| Purity | Borosilicate glass: SiO2 ~81%, B2O3 ~13%, Na2O ~4%, Al2O3 ~2%; extractables: USP Type I limits; heavy metals: within Type I glass specification; PTFE: virgin resin. |
| Concentration | Not applicable — empty storage containers. |
| Activity / Unit Definition | Not applicable — glassware. |
| Molecular Weight | Not applicable — glass and polymer materials. |
| Source / Origin | Borosilicate glass: molded from virgin glass melt (no recycled content); polypropylene caps: injection molded from medical-grade PP; PTFE liner: die-cut from virgin PTFE sheet; no animal-derived components. |
| pH Range / Optimal pH | Borosilicate glass stable for aqueous solutions pH 1.0-9.0 for extended storage; pH 1.0-12.0 for short-term use; alkaline solutions pH >9 at elevated temperature may slowly etch glass — for long-term storage of strong bases, use polypropylene or PTFE bottles. |
| Shipping Conditions | Ambient temperature; heavy padding to prevent breakage in transit. |
| Expiration Date / Stability | Indefinite (glass); replace caps every 10 years or if PTFE liner is damaged. |
| Regulatory / Compliance | For research use only; not for diagnostic or therapeutic use. USP Type I glass suitable for pharmaceutical packaging per USP <660>. Not intended for human injection of stored solutions without further sterilization validation. |
| Compatibility | Compatible with: acids (HCl, H2SO4, HNO3, acetic, formic, phosphoric), bases (NaOH, KOH at concentrations <1 M), organic solvents (acetone, acetonitrile, methanol, ethanol, isopropanol, DMSO, DMF, THF, dichloromethane, chloroform, hexane, ethyl acetate), aqueous buffers and salt solutions, protein and enzyme solutions, nucleic acid solutions, fluorophore and dye solutions, and standard laboratory reagents. Not compatible with: hydrofluoric acid (HF) — etches glass; strong alkaline solutions (>1 M NaOH/KOH) for extended storage at elevated temperature — etches glass; and some fluoride-containing solutions (NH4F, TBAF) which may etch glass. PTFE cap liner: compatible with essentially all chemicals except molten alkali metals and fluorine gas under extreme conditions. |
| Recommended Buffer System | Not applicable — storage container. |
| Application Notes / Precautions | Before first use, wash bottles thoroughly with laboratory detergent, rinse with tap water, then rinse 3x with ultrapure water, and allow to air-dry. For trace metal analysis solutions, soak bottles in 10% HNO3 for 24 h, then rinse thoroughly with ultrapure water. For organic trace analysis, rinse with the solvent to be stored, then dry in a clean oven at <100 C. Cap bottles tightly to prevent evaporation and contamination. The PTFE liner should face the bottle opening; do not overtighten (finger-tight is sufficient — overtightening may crack the cap or deform the liner). When autoclaving, loosen caps by half-turn to allow pressure equalization; tighten after cooling. Do not heat glass bottles directly on a hot plate; use a water bath or heating mantle. The graduated markings on the bottle are approximate (typically +/-5% accuracy); use graduated cylinders or volumetric flasks for precise volume measurement. |
| Batch-to-Batch Consistency | Capacity within +/-5% of nominal; cap leak-free; glass Type I USP classification verified; no visible defects. |
