Key Features
- Superior Borosilicate 3.3 Glass: Low thermal expansion coefficient, outstanding thermal‑shock resistance, safe for rapid temperature change without cracking。
- Excellent Chemical Inertness: Resistant to most acids, alkalis, salt solutions and organic solvents; minimal ion leaching to keep reagents uncontaminated.
- Autoclavable for Sterilization: Whole set (bottle, cap, pouring ring) can withstand 121°C high‑pressure steam sterilization for repeated lab usage.
- GL45 Standard Thread: Universal GL45 thread compatible with various lab accessories such as filter caps and sensor fittings, good interchangeability.
- Leak‑proof & Anti‑drip Design: Matching PP screw cap ensures tight sealing; pouring ring prevents liquid dripping while decanting liquids, avoid contamination.
- Permanent Graduation & Writing Area: Enamel scale fired into glass surface, will not wear off after repeated cleaning and autoclaving. Reserved writing spot for sample marking.
- High Light Transmittance: Clear glass for easy visual observation of liquid status; amber option for light‑sensitive reagents.
- Smooth Inner Wall: Easy to clean, reusable for multiple cycles; strict annealing treatment reduces internal stress for higher mechanical strength.
Applications
‑ Chemical laboratory reagent storage & sample preparation ‑ Pharmaceutical GMP testing, drug development ‑ Biotechnology, cell & microbial culture media preparation ‑ University teaching & scientific research experiments ‑ Environmental monitoring, water quality and soil sample collection ‑ Food safety quality control ‑ Petrochemical industry sampling and liquid storage
Suitable for water sample collection for microbiological analysis.
Wide-mouth bottle with a screw-on cap.
Does not react with components present in water samples.
Both the glass bottle and the cap are autoclavable and can withstand autoclave sterilization.
Notes
- Avoid sudden extreme temperature impact beyond 150℃ thermal‑shock range.
- Cap temperature limit is 140℃; do not exceed temperature requirement during autoclave.
- Not recommended for use with highly corrosive hydrofluoric acid and strong alkaline at high temperature.
- Graduation marks serve as volume reference only, cannot be used for precise metering analysis.
