Applications

• Protein Concentration, Nucleic Acid Concentration, Buffer Exchange, Dialysis, Desalting

Characteristic

• All materials are confirming to USP Class VI . In total, five molecular weight cut-off
• (MWCO) options are available, meeting the needs of filtering molecules in different sizes.
• The filter is structurally designed with a high-performance vertical single- (0.5 mL)/double-sided (5 mL & 15 mL) PES filtration membrane, featuring a larger effective filtration area and a higher flow rate.
• The 5 mL and 15 mL tubes are provided with supports, improving the stability of the structure, supporting a higher centrifugal speed, and reducing the filtration time.
• The protein recovery is increased to over 80%.
• There is a printed scale and a white area for writing on the tube, facilitating the identification and marking.
• DNase-free, RNase-free, non-pyrogenic

*The products are strictly controlled in accordance with ISO 13485 and ISO 9001 standards, and undergo strict leak-proof and chemical compatibility tests to ensure quality.

Dead stop

• Avoid spinning to dryness: The process does not require complete drying through spinning.
• Predictable concentration factor: Provides a reliable and predictable concentration factor.
• No need for calibration: No calibration is necessary when running multiple samples in parallel.
• Vertical membranes: The membranes are aligned with the filtrate instead of being perpendicular, leading to fewer clogs, reduced waste, and faster filtration.
• Single-step concentration: Capable of achieving 25- to 80-fold concentration in a single step.

Reliable

• Spin precious samples confidently: The unit allows for spinning precious samples with confidence.
• Robust and sleek design: The unit is designed to be sturdy and aesthetically pleasing.
• Leakage prevention: The unit is designed to prevent leakage, ensuring the integrity of the samples.
• Neutrally charged ultrafiltration membrane: The membrane has a neutral charge, resulting in low binding properties that enhance flux (filtration rate) and sample recovery.
• Excellent chemical resistance: The membrane exhibits high resistance to chemical substances, ensuring compatibility with a wide range of samples and solvents.
• Very low extractable: The membrane has minimal leaching of substances, ensuring that the filtered samples are not contaminated with unwanted compounds.
