How to Choose the Best Lab Tubes
Material Matters
Glass: Borosilicate glass is favored for its excellent chemical resistance and ability to withstand high temperatures and autoclaving. It's ideal for reactions, distillations, and storing sensitive chemicals. However, it is fragile and can break.
Plastic: Common plastics include polypropylene (PP), polyethylene (PE), and polystyrene (PS). PP and PE offer good chemical resistance and are more durable and shatter-resistant than glass. Polystyrene is often used for disposable culture tubes due to its clarity but has limited chemical resistance.
Size and Volume Considerations
Lab tubes come in a wide range of volumes, from a few milliliters to hundreds of milliliters. The required volume depends on the scale of your experiments and the quantity of substances you need to handle.
Consider the dimensions (diameter and length) if you need tubes to fit specific racks, centrifuges, or heating blocks.
Closure Types for Secure Storage
Open-top: Suitable for short-term storage or experiments where easy access is needed, but offer no protection against evaporation or contamination.
Screw caps: Provide a tight seal, minimizing evaporation and preventing contamination. They are ideal for storing samples long-term or for transport.
Snap caps/Plug caps: Offer a quick and easy sealing solution, good for general laboratory use where a high degree of airtightness isn't critical.
Fitted plugs: Often used for specific glassware like test tubes, providing a basic seal.
Specialized Features
Some tubes are designed for specific applications, such as centrifuge tubes with conical bottoms for pelleting, culture tubes with sterile packaging, or cryogenic tubes for ultra-low temperature storage.
Look for features like graduated markings for volume estimation, frosted writing surfaces for labeling, or specific chemical treatments for enhanced performance.
Frequently Asked Questions
What is the difference between borosilicate glass and soda-lime glass for lab tubes?
Borosilicate glass offers superior resistance to thermal shock and chemicals compared to soda-lime glass. This makes it the preferred choice for applications involving heating, boiling, or exposure to corrosive substances.
Are plastic tubes safe for storing chemicals?
Many plastic tubes, especially those made from polypropylene or polyethylene, exhibit good chemical resistance. However, it's essential to check the compatibility of the specific plastic with the chemical being stored, as some plastics can degrade or leach into the contents.
What is the best type of tube for long-term sample storage?
For long-term storage, tubes with secure screw caps are generally recommended to prevent evaporation and contamination. Cryogenic tubes are specifically designed for ultra-low temperature storage, such as in liquid nitrogen.
Can I autoclave plastic lab tubes?
Some plastic tubes, particularly those made from polypropylene, can be autoclaved. Always check the manufacturer's specifications to confirm if a specific plastic tube is designed for sterilization by autoclaving, as not all plastics can withstand the heat and pressure.
What are graduated tubes used for?
Graduated tubes have markings along their side indicating volume measurements. They are useful for approximating the volume of liquids when precise measurements are not critical, saving the need for a separate graduated cylinder in some scenarios.
