Ahlstrom 1510-1100 Glass Microfiber Filter Paper, Grade 151, 110 mm, 100/pk

Grade 151 is designed for high-efficiency filtration of very fine particles, making it ideal for applications such as environmental testing, biochemical sample preparation, and filtration of precipitated proteins. It is commonly used in laboratory workflows requiring high purity and accuracy.

This filter paper offers fine particle retention down to approximately 0.7 µm, providing performance comparable to membrane filters while maintaining faster flow rates.

Glass microfiber filters provide higher loading capacity, faster filtration, and better chemical and thermal resistance. They are binder-free, which ensures low extractables and improved analytical accuracy, especially in sensitive lab applications.

Yes, Grade 151 is often used as a prefilter in combination with membrane filters, helping to remove fine particulates and extend the life of downstream filters. This is especially useful when working with viscous or particle-heavy samples.

The 110 mm diameter is ideal for standard laboratory filtration setups, including vacuum filtration and funnel systems. It provides a balanced surface area for efficient filtration without excessive material use, making it suitable for routine and analytical workflows.
