Frequently asked questions
Are these caps compatible with all 13 mm tubes?
These caps are engineered specifically for 13 mm diameter tubes. Due to their precision-molded design by Sarstedt, they provide a consistent and reliable seal on standard laboratory tubes of this size.
Is the skirted design better than standard caps?
Yes. The skirted design provides an extra layer of protection by overlapping the rim of the tube. This creates a much more reliable seal, significantly reducing the risk of accidental leakage or evaporation during sample handling.
Can I use these for sterile applications?
These specific caps are non-sterile. They are intended for standard laboratory use, storage, and processing where a sterile environment for the closure itself is not required.
Are these easy to handle manually?
Yes, they feature vertical ribbing along the upper circumference. This grip-friendly design makes it much easier to apply or remove the caps manually, even when wearing laboratory gloves.
Is the seal tight enough for transport?
The skirted design is specifically engineered for a secure, tight seal. While they are excellent for storage and handling, they are designed primarily to prevent leakage and contamination during routine lab procedures.
Are these a genuine Sarstedt product?
Yes, these are authentic Sarstedt closures (Model 65.724). Choosing Sarstedt ensures you are getting laboratory-grade precision and consistent compatibility across your supply.
What material are these caps made from?
These caps are manufactured from high-quality, durable polystyrene. This material is chosen for its structural integrity, ensuring the caps remain secure and maintain their shape during routine laboratory use.
Is the case size suitable for high-volume labs?
Absolutely. These are provided in a bulk case of 10,000 units, making them an ideal, cost-effective solution for facilities that handle a high volume of samples daily and require a steady, consistent supply.
How should I store these caps?
As these are non-sterile polystyrene components, they should be kept in a cool, dry, and clean environment. Maintaining them in their original packaging will help keep them free from dust and contaminants before use.
Are these caps transparent?
Yes, they feature a clear, semi-transparent appearance. This allows for easy visual inspection of the tube contents without needing to remove the cap.
