Our Amber Screw-Cap Reagent Bottle is manufactured from soda‑lime glass (with borosilicate glass 4.0 or 3.3 optional), with amber glass effectively blocking UV and visible light. Featuring a standard GL45 threaded neck and a secure sealing cap, it provides a convenient and reliable sealing solution for light‑sensitive reagent storage. The cap offers excellent sealing performance and can withstand autoclaving — making it the ideal choice for pharmaceutical, biological, and food testing laboratories requiring light‑sensitive reagent protection.

Product Description
The Amber Screw-Cap Reagent Bottle is the ideal modern storage solution for light‑sensitive reagents, manufactured from soda‑lime glass (with borosilicate glass 4.0 or 3.3 optional). The amber glass effectively blocks UV and visible light to protect photolabile reagents from light‑induced degradation. The bottle features a standard GL45 threaded neck with a high‑quality sealing cap, providing excellent sealing performance that prevents evaporation, leakage, and contamination. The cap can withstand 121°C autoclaving, meeting the stringent requirements of pharmaceutical, biological, and food testing laboratories for light‑sensitive reagent storage.
Three Material Options
Soda‑lime glass (standard): Good chemical stability, moderate thermal expansion coefficient — cost‑effective for routine laboratory use
Borosilicate glass 4.0 (optional): Thermal expansion coefficient 4.0×10⁻⁶/K, thermal shock resistant to 250°C — improved chemical stability over soda‑lime
Borosilicate glass 3.3 (optional): ISO 3585 compliant, extremely low thermal expansion (3.3×10⁻⁶/K), thermal shock resistant to 280°C — ideal for autoclaving and demanding applications
Key Features
GL45 standard thread: DIN 168‑1 compliant, compatible with all GL45 accessories
Amber light protection: Amber glass effectively blocks UV and visible light (290–500nm) to protect light‑sensitive reagents
High‑quality sealing cap: Integrated sealing ring provides excellent leak‑proof and evaporation‑proof performance
Autoclavable: Cap withstands 121°C, 15psi autoclaving for sterile applications
Quality Assurance
Every bottle undergoes rigorous dimensional inspection, seal integrity testing, and visual examination to meet the high standards required in professional laboratories.
Note: Amber Screw-Cap Reagent Bottles feature the GL45 standard thread, compatible with all GL45 accessories including caps, connectors, and filtration units. When autoclaving, ensure the cap is slightly loosened to allow pressure equalization and prevent breakage. Select the appropriate material based on your requirements — soda‑lime for cost‑effectiveness, borosilicate 4.0 for improved thermal resistance, and borosilicate 3.3 for the highest thermal and chemical resistance.
Applications
Typical Uses
Pharmaceutical industry
Light‑sensitive API, intermediate, and finished product storage — GMP compliant
Biology labs
Light‑sensitive media, buffers, and sera — sterile storage with light protection
Chemistry labs
Light‑sensitive organic solvents, standard solutions, and corrosive reagents
Food testing
Light‑sensitive food additives and standard solutions
Environmental monitoring
Light‑sensitive water and soil sample collection and storage
Compatibility Recommendations
Amber Bottle + GL45 Cap
Standard configuration for general light‑sensitive storage
Amber Bottle + Filter Cap
Ideal for light‑sensitive sterile solution storage and dispensing
Amber Bottle + Aluminum Foil
Additional light protection when needed
Amber Bottle + Label
Use light‑sensitive labels with "Protect from light" warnings
Tip: The Amber Screw-Cap Reagent Bottle combines light protection with GL45 standard sealing — the ideal solution for safe, standardized photolabile reagent storage. For applications requiring higher thermal and chemical resistance, we recommend choosing borosilicate 4.0 or 3.3.
Operation & Maintenance
Amber Screw-Cap Reagent Bottle User Guide
03
Before Use
Inspect for cracks, chips, or scratches before use
Ensure the bottle is clean and dry to prevent contamination of reagents
Check that the cap's sealing ring is intact — no deformation or damage
Ensure proper thread engagement — cap rotates smoothly when tightened
04
Light‑Sensitive Storage Procedure
Fill with light‑sensitive reagent — do not exceed 80% capacity
Align the cap with the neck and tighten clockwise to a moderate level (do not overtighten)
Wipe the exterior clean and apply a light‑sensitive label (name, concentration, date, "Protect from light")
Store in a cool, dry, well‑ventilated area away from direct sunlight
The amber glass itself provides light protection — additional wrapping (aluminum foil) is optional
05
Autoclaving Procedure
Before autoclaving, loosen the cap by half a turn to allow pressure equalization
Autoclave at 121°C, 15psi for 15–20 minutes
Allow to cool to room temperature before tightening the cap
After autoclaving, inspect the sealing ring for integrity
06
Cleaning & Maintenance
Clean promptly after use to prevent residue from hardening
For routine cleaning, use detergent with a bottle brush, rinse 3× with distilled water
For stubborn residues, soak in dilute acid or specialty cleaning solution
Replace the sealing ring periodically to maintain sealing performance
Allow to air‑dry inverted on a draining rack
Care & Notes
Show care & notes
Safety Notice
Always inspect for cracks or damage before use — damaged bottles may break during use
When autoclaving, always loosen the cap — internal pressure may otherwise cause the bottle to burst
For volatile or corrosive light‑sensitive reagents, ensure the cap is fully tightened and the sealing ring is intact
Do not
Do not place reagent bottles directly on hot plates or open flames
Handle with care — avoid impact and rough handling
