Who Should Buy?
-
Biotechnology Research
Ideal for researchers needing to concentrate proteins or nucleic acids efficiently in small sample volumes.
-
Pharmaceutical Applications
Useful for drug formulation and purification processes, ensuring high-quality sample preparation in laboratories.
-
Clinical Labs
Perfect for clinical labs that require reliable filtration and concentration of biological samples before analysis.
-
Large Volume Processing
Not suitable for applications requiring larger volumes beyond 15mL, as it caps the sample capacity.
-
High-Viscosity Solutions
May struggle with highly viscous solutions, leading to inefficient filtration and longer processing times.
-
Budget-Conscious Users
Could be cost-prohibitive for users with limited budgets, given the purchase of packs and filtration costs.

Question:
What is the purpose of the Briscale 10kDa Ultra Centrifugal Filter?
Answer: The Briscale 10kDa Ultra Centrifugal Filter is designed to facilitate the purification and concentration of biomolecules such as proteins, peptides, and nucleic acids. By employing a 10kDa molecular weight cutoff, it effectively removes smaller contaminants while retaining larger molecules for further analysis. This is particularly useful in biochemistry and molecular biology, where concentrated specimens are often essential for enzyme assays or structural studies. -
Question:
Can the Briscale centrifugal filters be reused, or are they single-use only?
Answer: The Briscale centrifugal filters are intended for single-use applications, ensuring optimal performance and preventing cross-contamination between samples. While some users may inquire about cleaning methods for reuse, the integrity of the RC membrane and the potential for residual contaminants make single-use the safest choice. Researchers often stock multiple units to streamline their workflows when handling various samples, ensuring reliable and consistent results. -
Question:
What kind of samples can be processed with the Briscale 15mL filter units?
Answer: The Briscale 15mL filter units are versatile and can process a wide range of samples, including cell lysates, culture media, and biological fluids. Whether you are concentrating proteins from cell cultures or removing salt from nucleic acid solutions, these filters perform exceptionally well. Their compatibility with various sample types makes them an ideal choice in a laboratory setting, especially for those working with sensitive biological materials. -
Question:
How do I choose the right molecular weight cut-off for my application?
Answer: Choosing the right molecular weight cut-off (MWCO) for your application depends on the size of the biomolecules you aim to retain or remove. The 10kDa MWCO of the Briscale filters is well-suited for retaining large proteins while allowing smaller molecules, like salts and impurities, to pass through. It's crucial to understand the nature of your samples beforehand, as this will determine the efficiency and effectiveness of the filtration process in your experiments. -
Question:
What is the maximum spin speed recommended for these filters?
Answer: The recommended maximum spin speed for the Briscale 10kDa Ultra Centrifugal Filter is typically around 4,000 to 5,000 x g, depending on the centrifuge model and the specific demands of your experiment. Adhering to this guideline helps prevent membrane rupture and ensures optimal filtration results. Users often conduct preliminary tests to fine-tune their centrifuge settings and achieve the best possible outcomes for their specific sample types. -
Question:
Are these filters compatible with organic solvents?
Answer: The Briscale Ultra Centrifugal Filters are designed primarily for aqueous samples and may not be suitable for processing organic solvents. Using organic solvents can compromise the integrity of the RC membrane, leading to reduced filtration performance or even membrane failure. For applications involving organic solvents, it is advisable to consult technical specifications and consider alternate filter options designed to withstand such environments. -
Question:
How do I properly use the Briscale 15mL ultrafiltration tubes?
Answer: To use the Briscale 15mL ultrafiltration tubes, fill the sample into the upper chamber, securely cap it, and place it in a suitable centrifuge. Set your centrifuge to the desired speed and time based on your sample type and volume. After centrifugation, collect the concentrated sample from the lower chamber. It’s recommended to perform a small test run with known samples to refine your process before scaling up to larger batches. -
Question:
What is the storage requirement for these filters?
Answer: The Briscale 10kDa Ultra Centrifugal Filters should be stored in a clean and dry environment. It’s recommended to keep them in their original packaging until ready for use to protect them from contamination. Avoid exposure to extreme temperatures that may affect the integrity of the membrane material. Proper storage ensures that the filters maintain their functionality, allowing for reliable results during your applications. -
Question:
Can these filters handle high viscosity samples?
Answer: While the Briscale 10kDa Ultra Centrifugal Filters can handle a variety of sample viscosities, extremely viscous samples may lead to reduced filtration efficiency or prolonged processing times. For samples with high viscosity, it might be beneficial to dilute them with a compatible buffer before filtration. This adjustment helps to maintain optimal flow rates and ensures effective separation during the filtration process. -
Question:
Where can I buy Briscale Pack of 4 10kDa Ultra Centrifugal Filter 15mL Ultrafiltration Centrifuge Tube Unit with RC Membrane?
