Frequently asked questions
Does this cap provide a truly secure seal?
Yes, these caps are precision-molded from low-density polyethylene (LDPE). This high-quality material is specifically engineered to ensure a tight, reliable seal that remains secure during rigorous laboratory procedures, including:
- Centrifugation
- Agitation
- Refrigeration
Is the design easy to remove?
Absolutely. Each cap is designed with a single-thumb tab, which allows for quick and ergonomic removal. This feature is particularly helpful for maintaining efficiency in high-throughput workflows.
Will these caps save space in my racks?
Yes. The design is specifically optimized for space efficiency. Because of the single-thumb tab configuration, you can arrange your tubes in close proximity within standard laboratory racks without the closures interfering with one another.
Are these safe for individuals with latex sensitivities?
Yes, these closures are 100% latex-free. They are manufactured without natural rubber latex, ensuring they meet standard laboratory safety protocols for all users.
Which types of tubes are these compatible with?
These caps are designed for 13 mm diameter tubes, making them highly versatile for various laboratory needs, including:
- Blood drawing tubes
- Glass test tubes
- Plastic culture tubes
What is the primary material used for these caps?
The closures are constructed from high-quality Low-Density Polyethylene (LDPE). This material was chosen for its flexibility and ability to create a robust, consistent snap-fit seal.
How many caps are provided in each order?
Each bag contains 1000 individual snap cap closures, providing a high-volume supply perfect for busy clinical or research environments.
Are these caps suitable for refrigeration?
Yes. The LDPE material maintains its integrity and secure sealing properties even during refrigeration, making them a reliable choice for sample storage.
Is the material durable during centrifugation?
Yes, the precision-molded construction is designed to withstand the physical demands of centrifugation, ensuring your samples remain securely contained throughout the process.
What is the specific diameter of these closures?
These caps are engineered specifically for 13 mm diameter tubes. Please ensure your glass or plastic test tubes match this diameter for an optimal, airtight fit.
