Sampling Bottle FAQ
Q: How should I clean sampling bottles before use?
A: For general applications, rinse with deionized water 3 times. For trace analysis, soak in 10% nitric acid for 24 hours followed by triple rinsing with ultrapure water. Always dry completely before use to prevent contamination.
Q: What's the shelf life of unused sampling bottles?
A: Properly stored sampling bottles have virtually unlimited shelf life. Keep them in original packaging in a clean, dry environment away from direct sunlight. For sterile bottles, check the sterilization indicator and expiration date (typically 2-5 years).
Specialty Sampling Bottles
We offer specialized sampling bottle variants including:
- Amber bottles for light-sensitive samples
- Wide-mouth bottles for viscous liquids
- Pre-sterilized bottles for microbiology
- Certified clean bottles for ultra-trace analysis
Sampling Bottle FAQ
Q: Can sampling bottles be reused?
A: Yes, but with limitations. HDPE bottles can typically withstand 5-10 sterilization cycles before material degradation occurs. Glass bottles are more durable but require careful inspection for cracks. Never reuse bottles for different sample types without proper decontamination to prevent cross-contamination.
Proper Sampling Techniques
Always follow these best practices when using sampling bottles:
- Select appropriate bottle material based on sample characteristics
- Fill to 80% capacity to allow for thermal expansion
- Label immediately with permanent marker or pre-printed labels
- Store samples at recommended temperatures
- Transport in approved containment systems
Industry Applications
| Industry | Common Uses | Recommended Type |
|---|---|---|
| Environmental | Water quality testing | EPA-certified bottles |
| Pharmaceutical | Raw material sampling | Pre-sterilized glass |
| Food & Beverage | Quality control | Wide-mouth HDPE |
| Petrochemical | Fuel analysis | Chemical-resistant HDPE |
Sampling Bottle FAQ
Q: How do I choose between HDPE and glass sampling bottles?
A: Consider these factors: For harsh chemicals or high temperatures, choose glass. For field sampling or shipping, HDPE is more practical. When analyzing for trace metals, glass prevents adsorption. For organics analysis, HDPE is often preferred. Always check your analytical method requirements.
