Feature Of Water Sample Bags
- High-Quality PE Material: Made of high-molecular polyethylene (PE), this bag offers excellent flexibility and tensile strength. It is chemically resistant and resistant to cracking.
- Screw-On Spout: Equipped with a sealed screw cap, it opens and closes smoothly and seals securely. It allows for easy control of pouring speed to prevent sample spillage and contamination. Screw opening: 22 cm. Other sizes available upon request.
- Stand-Up Design (Stand-Up Pouch): The widened base allows for a stable, stand-up operation without the need for additional support. It is suitable for use on benchtops or in the field, making it easy to label, record, and collect samples.
- Writable Labeling Area: The bag features a designated writing area for marking sample number, sampling location, date, and other information, facilitating sample tracking and batch management.
- Multiple Sizes Available: Available in capacities from 250 mL to 1000 mL, supporting OEM customization and batch sterilization. We also offer sterile sample bags with wire closure.
- Sterile, Ready-to-Use Packaging: Pre-sterilized, preventing cross-contamination.
FAQ Of sterile sample bags for liquid collecting
How to use water sampling bags?
- Take a sterile water sample collection bag, pinch the neck of the bottle, and unscrew the cap.
- Gently shake the bag to fully expand it.
- Keep your eye level with the scale line and add the collected sample to the bag, taking care to avoid contaminating the bottle opening with your fingers or other objects.
- Finally, tighten the cap.
What are the advantages of a screw-top design for water sample bags?
The screw-top design effectively prevents sample leakage while also making it easier to control the pouring flow and reducing the risk of contamination during handling.
What is the difference between water sampling bags with sodium thiosulfate and those without?
The main difference lies in sample preservation and intended analysis.
1. Disposable Liquid Bag With Sodium Thiosulfate
- Feature: These bags contain a pre-added amount of sodium thiosulfate (Na₂S₂O₃), either as a liquid or powder.
- Function: Sodium thiosulfate neutralizes residual chlorine in the water sample, preventing it from affecting microorganisms or chemical components.
- Applications:
- Microbial testing of drinking water (total coliforms, E. coli, etc.)
- Environmental water analysis where residual chlorine may interfere with results
- Advantages:
- Protects microbial viability and chemical integrity.
- Ensures accurate and reliable analytical results.
2. Liquid Sampling Bag (Without Sodium Thiosulfate)
- Feature: These sterile bags are pure and do not contain any chemical additives.
- Applications:
- Sampling for chemical analysis where residual chlorine is not a concern
- Situations where laboratories add preservatives themselves
- Advantages:
- No interference with chemical composition.
- Maintains the original state of the water sample.
