COBETTER Bottle Top Filters PES PVDF Lab Filtration

Description

Product Overview

COBETTER Bottle Top Filters are designed for high-performance laboratory filtration, utilizing asymmetric PES membranes for superior flow rates and hydrophilic PVDF membranes to minimize protein binding. Constructed with polysulfone bottles and lids, along with HDPE funnel adapters and screw caps, these filters are available in 500 ml and 1000 ml sizes with options for 0.2μm PES or hydrophilic PVDF membranes. Each package includes easy-read graduations and ergonomic grips for enhanced handling, ensuring precise and efficient filtration processes in demanding research environments.

Usage

These bottle top filters are ideal for filtering cell culture media, buffers, and reagents in research laboratories, providing reliable sterilization and clarification. They are commonly used in biotechnology, pharmaceutical development, and academic research settings where maintaining sample integrity is critical. The target audience includes lab technicians, researchers, and scientists working with sensitive biological samples that require consistent, low-binding filtration to avoid contamination and ensure accurate results.

Why Choose Us

COBETTER Bottle Top Filters stand out due to their compliance with ISO 9001:2015 quality management systems and USP Class VI standards, guaranteeing safety and reliability. Gamma irradiation at 25-45 kGy ensures sterility, while the low endotoxin levels (< 0.25 EU/mL) make them suitable for critical applications. The combination of high flux membranes and durable materials provides long-lasting performance, reducing the need for frequent replacements and supporting consistent laboratory workflows.

FAQ

What applications are these filters suitable for?

They are designed for filtering cell culture media, buffers, and reagents in research laboratories, ensuring sterility and clarity for sensitive biological samples.

How do I choose between PES and PVDF membranes?

PES membranes offer higher flow rates, while PVDF membranes provide lower protein binding; select based on your specific sample requirements to optimize performance.

Are these filters sterile and safe for use?

Yes, they undergo gamma irradiation and comply with USP Class VI standards, with aqueous extraction containing less than 0.25 EU/mL endotoxins for safe laboratory use.

What sizes and packaging options are available?

Available in 500 ml (9 or 18 per pack) and 1000 ml (4 per pack) configurations, with options for membrane types to suit different laboratory needs.

How do I handle disposal or recycling of used filters?

Follow local regulations for laboratory waste disposal; the materials are durable but should be treated as biohazardous if contaminated with biological samples.
