A Simple and Sustainable Pathway to Lab Filtration

The process of filtration can be found across many diverse industry applications, and is utilised for things like mineral processing, sewerage treatment, and even asbestos analysis for the maintenance of healthy spaces.

Filtration of water and gas with precise separation technologies is an integral part of many laboratories' workflow, particularly for cell culture, protein research, water testing, and bioprocess design.

For routine sample filtration, it’s important to choose the most compatible filter type and material. Scientific accuracy often relies on the compatibility of the implements used, but this is sometimes overlooked for the sake of convenience, says Claudia Biantara, Portfolio Leader for Consumables at Thermo Fisher Scientific.

“It is our aim to make this selection process easier and more streamlined, so that laboratories can spend more time on the work at hand. We have a comprehensive range of filters available through our partnership with Cytiva Whatman, who are trusted by the industry for their premium-quality products.”

Cited in the EPA, ASTM, and ISO protocols for environmental monitoring, Cytiva Whatman’s range encompasses a broad selection of filter types including Glass Microfibre or Cellulose Filter Paper, Extraction Thimbles, and Low-metal TCLP.

As a global provider of technologies aimed at advancing development for manufacturing and the delivery of therapeutics, Cytiva leverages on a heritage of innovation dating back hundreds of years. Aligning with Thermo Fisher Scientific’s sustainability values, they are focused on closing the loop in the plastics value chain, rethinking packaging, and using resources like water responsibly.

“We truly believe that when it comes to the scientific workflow, a small change today will make a big impact tomorrow,” Claudia Biantara says. “Our selection of Cytiva Whatman products gives customers a simpler way to meet these sustainability goals, while also maintaining a high level of accuracy.”

Combining fine particle retention with good flow rate

The Whatman Binder-Free Glass Microfibre Filters (Grade GF/C) are designed for processes involving air or water monitoring. They can be used as pre-filters for membranes, in cell harvesting, liquid scintillation counting, marine chemistry and biochemistry, particularly for collecting suspended solids in potable water, natural and industrial wastes.

Optimising solid-liquid extraction studies

Whatman’s Cellulose Soxhlet Extraction Thimbles are commonly utilised for lipid, waste, gas, and pesticide analysis, as well as food and soil samples. Designed with mechanical strength and retention in mind, they are constructed from high-quality alpha cellulose cotton linter for compatibility with automated Soxhlet extractor systems.

A trusted product that’s ready to use

The Whatman 934-AH Glass Microfiber Filters are now available in a ready-to-use (RTU) format, eliminating the need for pre-treating prior to use. The most widely used filter for total suspended soil analysis, they feature an aluminium pan for superior fine particle retention at high flow rates.

This renders them highly suited to water monitoring applications such as rivers, lakes, and coastal waters, as well as discharge from industrial or wastewater treatment plants.
