Features:
Specifications:
-
A test tube is a glass tube with one end open and the other end closed.
-
The closed end is rounded.
-
They are primarily used for qualitative assessment and comparison.
-
A common place to see these is the biochemistry lab.
-
When a large number of samples need to be tested and compared, test tubes are used to make this easier.
-
They are also easily capped with a rubber or glass stopper.
-
They are generally held in a test tube rack specifically designed for this purpose.
-
If heated or unsafe to touch with bare hands, a test tube tongs can be used to move them.NEVER heat a capped test tube.
Versatile Laboratory GlasswareOur borosilicate glass test tubes offer excellent chemical and temperature resistance, making them well-suited for a variety of laboratory purposes. With multiple sizes and capacities, these test tubes provide flexibility for chemical sampling, biological experiments, and routine lab work. Their smooth, transparent finish allows for easy observation and handling.
Built for Durability and ReusabilityDesigned for repeated use, these test tubes are easy to clean and can withstand both autoclaving and standard laboratory heating. Their uniformly rounded bottom and cylinder shape make them ideal for mixing and heating chemical solutions safely. The non-reactive glass is compatible with most laboratory reagents, ensuring reliable performance.
FAQ's of Test Tubes:
Q: How do I properly clean and sterilize these reusable glass test tubes?
A: To clean and sterilize the test tubes, rinse immediately after use, then wash thoroughly with laboratory detergent and water. For sterilization, place the tubes in an autoclave at the recommended conditions for borosilicate glass. This material is designed to withstand high temperatures without compromising integrity.
Q: What are the main benefits of using borosilicate glass test tubes in laboratory experiments?
A: Borosilicate glass test tubes offer excellent chemical resistance and high temperature durability. They do not easily react with most chemicals, ensuring your results remain uncontaminated. Their reusable nature also makes them cost-effective for repeated laboratory use.
Q: When should I choose a test tube without graduation markings?
A: Test tubes without graduation markings are ideal for qualitative experiments, general mixing, heating, or procedures where precise volume measurement is not required. This design keeps the glass robust and simplifies cleaning.
Q: Where can these test tubes be sourced in India?
A: These test tubes are widely available across India through authorized laboratory equipment dealers, distributors, exporters, manufacturers, retailers, suppliers, traders, and wholesalers. They are standard items in most scientific supply catalogs.
Q: What capacities and sizes are available for these laboratory test tubes?
A: The test tubes come in various diameters (e.g., 10mm, 12mm, 16mm), lengths (commonly 75mm, 100mm, 150mm), and typical volume capacities such as 5ml, 10ml, and 15ml, allowing selection based on specific experimental requirements.
Q: Are these glass test tubes suitable for heating substances directly over a flame?
A: Yes, the borosilicate glass used in these test tubes is designed for excellent thermal resistance. It can safely withstand direct laboratory heating, such as with a Bunsen burner, provided proper precautions are taken.
Q: What process should I follow to ensure the safety and longevity of these test tubes?
A: Handle the test tubes carefully to avoid mechanical shocks, especially at the rims and bottoms. Always allow the tubes to cool gradually after heating and avoid rapid temperature changes. Inspect regularly for cracks or chips and retire any damaged tubes from service.
