The unassuming 90ml HDPE narrow mouth reagent bottle is a workhorse in both laboratory and travel settings. Made from high-density polyethylene (HDPE), a robust and chemically resistant plastic, these bottles offer a convenient size (90 milliliters) for storing and handling moderate quantities of liquids. The narrow mouth design allows for controlled dispensing and minimizes spills, making them a versatile tool for various applications.
Applications in Laboratory Settings
The laboratory is where the 90ml HDPE narrow mouth reagent bottle truly shines. Its durability and chemical compatibility make it ideal for storing and dispensing a wide range of laboratory chemicals.
- Chemical Storage and Dispensing
- Acids: HDPE offers good resistance to many diluted acids, commonly used in laboratories. However, it's crucial to check the specific acid and concentration for compatibility. For instance, sulfuric acid can degrade HDPE over time.
- Bases: Strong bases can react with HDPE. Sodium hydroxide (NaOH) solutions should be stored in glass containers for safety. Weaker bases like ammonium hydroxide (NH4OH) may be suitable for short-term storage in HDPE, but caution is advised.
- Solvents: HDPE is an excellent choice for storing various organic solvents routinely used in labs, such as ethanol, methanol, acetone, and isopropanol. These solvents are unlikely to react with the HDPE material.
- Experimental Use：These bottles are perfect for holding reagents used in specific laboratory procedures.
Dilution Techniques: Preparing dilutions is a fundamental laboratory skill. A 90ml bottle can be used to store the stock solution and dispense precise volumes for dilution.
Staining Protocols: Biological staining procedures often involve multiple staining solutions. These bottles can hold the different stains used in the process.
Solution Preparation and Transport:
The leak-proof design of these bottles with lids makes them ideal for preparing and transporting small volumes of solutions
- Buffers: Phosphate-buffered saline (PBS) and other commonly used buffers can be prepared in these bottles and transported to different lab areas.
- Mobile Phases: In chromatography techniques, mobile phases are the solvents used to elute components from a column. A 90ml bottle can be used to prepare and transport a small volume of mobile phase for specific analyses.
- Standards and Reference Materials
The translucency of the HDPE allows for easy identification of contents, making these bottles suitable for storing reference materials or standards. These might include pre-made solutions of known concentrations used for calibration purposes in various assays.
Applications for Travel
The benefits of 90ml HDPE narrow mouth reagent bottles extend beyond the laboratory. Their compact size, leak-proof design, and compliance with travel regulations make them valuable companions for any traveler.
TSA-Compliant Carry-on Liquids
The Transportation Security Administration (TSA) enforces the 3-1-1 rule for liquids in carry-on luggage. This regulation restricts passengers to containers holding no more than 3.4 ounces (100 milliliters) of liquids, gels, aerosols, creams, and pastes. A 90ml bottle falls perfectly within this limit, allowing travelers to bring essential liquids on board.
Travel-Sized Toiletries
Packing light is key for many travelers, and these bottles provide a convenient way to carry essential toiletries in TSA-approved sizes. Examples include:
- Contact lens solution
- Hand sanitizer
- Mouthwash
- Facial cleanser
- Lotion (consider viscosity)
- Sunscreen (consider viscosity)
- Choosing the Right Bottle
While HDPE offers good chemical resistance, it's important to check the specific chemicals you plan to store for compatibility. Some manufacturers may offer HDPE bottles with additional liners or coatings for enhanced chemical resistance.
The narrow mouth design is ideal for controlled dispensing but may not be suitable for liquids with high viscosity. For thicker liquids like lotions or creams, consider wider mouth bottles specifically designed for easier dispensing.
Additional Applications
Beyond laboratories and travel, these versatile bottles can find uses in various settings:
Craft Supplies: Artists and hobbyists can use these bottles to store paints, inks, dyes, or small quantities of solvents.
Small Parts Storage: Beads, screws, nuts, bolts, and other small parts can be organized and stored in these bottles for easy access.
Sample Collection and Storage: In various fields, collecting and storing small samples is crucial. These bottles can be used to hold soil samples, plant specimens, or small insect collections.
Conclusion
The 90ml HDPE narrow mouth reagent bottle is a testament to the power of simple design and quality materials. Its durability, leak proof design, and compliance with regulations make it a versatile tool for a surprising variety of applications. From the precise world of scientific research to the practicalities of travel, these bottles offer a reliable and convenient solution for storing, transporting, and dispensing liquids.
