Bacteriostatic Water Glass vs Plastic Container
Bacteriostatic water glass vs plastic container is a crucial consideration for research laboratories, as the choice of container material can affect the quality and integrity of the water. Bacteriostatic water is a type of water that contains 0.9% benzyl alcohol, which acts as a bacteriostatic agent to prevent the growth of microorganisms. For research-grade supply, see BAC Water Depot's 10 mL vial catalog.
Importance of Container Material
The choice of container material is critical in research applications, as it can affect the leachables and extractables of the water. Leachables refer to the substances that can leach into the water from the container material, while extractables refer to the substances that can be extracted from the container material into the water. Type I borosilicate glass is a popular choice for bacteriostatic water containers due to its low leachables and extractables profile. According to the USP <71> monograph, Type I borosilicate glass is suitable for use in pharmaceutical applications due to its high purity and resistance to corrosion. In contrast, plastic containers may contain additives and impurities that can leach into the water, affecting its quality and integrity. For example, a study published in the Journal of Pharmaceutical Sciences found that plastic containers can leach bisphenol A (BPA) into water, which can affect the growth of microorganisms.

Comparison of Glass and Plastic Containers
| Container Material | Leachables and Extractables | Cost | | --- | --- | --- | | Type I Borosilicate Glass | Low leachables and extractables | $9.99 (single) | | Plastic | High leachables and extractables | $7.99 (single) | | Type II Borosilicate Glass | Moderate leachables and extractables | $8.99 (single) |
As shown in the table, Type I borosilicate glass has the lowest leachables and extractables profile, making it the preferred choice for research applications. However, it is also the most expensive option. Plastic containers, on the other hand, have a higher leachables and extractables profile, but are cheaper.

Choosing the Right Container for Your Research
When choosing a container for your research, it is essential to consider the specific requirements of your application. For example, if you are working with sensitive biological samples, you may require a container with a low leachables and extractables profile to prevent contamination. On the other hand, if you are working with less sensitive samples, a plastic container may be sufficient.

Considerations for Laboratory Use
When using bacteriostatic water in laboratory applications, it is essential to consider the potential risks and hazards associated with its use. For example, bacteriostatic water can be a skin and eye irritant, and can cause respiratory problems if inhaled. It is also essential to follow proper handling and storage procedures to prevent contamination and exposure.

People Also Ask
What is bacteriostatic water?
Bacteriostatic water is a type of water that contains 0.9% benzyl alcohol, which acts as a bacteriostatic agent to prevent the growth of microorganisms. It is commonly used in research applications, such as peptide reconstitution and lyophilization.
What is the difference between bacteriostatic water and sterile water?
Bacteriostatic water and sterile water are both types of water that are used in research applications, but they have different properties and uses. Bacteriostatic water contains 0.9% benzyl alcohol, which acts as a bacteriostatic agent, while sterile water is free from microorganisms and other contaminants.
Can I use plastic containers for bacteriostatic water?
While plastic containers can be used for bacteriostatic water, they may not be the best choice due to their high leachables and extractables profile. Type I borosilicate glass is a preferred choice for research applications due to its low leachables and extractables profile.
How do I store bacteriostatic water?
Bacteriostatic water should be stored in a cool, dry place, away from direct sunlight and heat sources. It is also essential to follow proper handling and storage procedures to prevent contamination and exposure.
What is the shelf life of bacteriostatic water?
The shelf life of bacteriostatic water depends on the storage conditions and the quality of the water. Generally, bacteriostatic water has a shelf life of 2-3 years when stored properly.
Can I use bacteriostatic water for human or veterinary use?
No, bacteriostatic water is for research and laboratory use only, and should not be used for human or veterinary use. It is essential to follow proper handling and storage procedures to prevent contamination and exposure.
