Whatman is dedicated to providing the most advanced technology for sample preparation to meet the growing demands of the life sciences market. Whatman filters are used worldwide for research, analysis and quality control in pharmaceutical and biotechnology industries. These high quality filters are provided in a range of multiwell analytical plates for pharmaceutical and life science research. 


Whatman utilises a unique patented process to encapsulate the filter media which ensures no crosstalk or contamination between wells. This patented technology allows for use of a variety of Whatman filter media. In addition, to further optimise the filter plates for specific applications, novel polymers, surface treatments, well densities, profiles and accessories are incorporated into the process. Our microplate technology is applied by a team of engineers, scientists, polymer engineers and filtration experts to ensure Whatman is at the leading edge of new developments.

The Whatman multiwell range of products provided is extremely diverse. The novel design of the filter plates enables a large number of applications to be targeted. Applications for disciplines such as sample preparation, genomics, filter based assays and SPE are served by the multiwell approach to filtration technology. Some core applications include sample cleanup, cell-based immunoassay, isolation of nucleic acids, sterile filtration of biological samples and compound library generation using parallel synthesis procedures.

Biomek™ and liquid handling system accessories
Designed specifically for the Biomek™ 2000 and F/X liquid handling systems from Beckman-Coulter™, Whatman Adapter Collars eliminate many of the problems common to generic vacuum systems such as cross contamination, unnecessary collection steps and the need for spacer plates.

The adapter collars are offered in two sizes to accommodate the wide range of Whatman specialty filter and collection plates-small, to enable collection into standard 300 µL collection and filter plates (~14 mm high), and medium, to accommodate collection into 800 µL collection and filter plates (~30 mm high). Chemically resistant and easy to install, Whatman Adapter Collars ensure quality is maintained in a wide range of high throughput applications. When vacuuming to waste during wash steps, the 96 well Filtrate Director assures crosstalk-free filtration by isolating the flow from each well without collecting it.

BugStopper™ microplate capmat
Whatman BugStopper™ Capmats provide a simple and reliable method for venting cultures being grown in a 24 well microplate. This reusable sterile closure, which is produced using chemically resistant biosafe silicone rubber, incorporates hydrophobic microfilters which provide an ideal vent for each well.

More efficient than plastic lids, test comparisons confirm that BugStopper Capmats improve cell growth and significantly reduce evaporation. The silicone rubber portion of the capmat reseals after puncture, thus keeping cell cultures sterile during inoculation or aspiration.

Sterile Venting Closures for Microplate Cultures
  • More efficient than plastic lids. Perfect for extended growth of slow growing bacteria and fungi
  • Positive seal for every well. Significantly reduces evaporation rate and eliminates well-to-well cross-contamination
  • Autoclave and re-use. Cost-effective; repeated autoclave cycles do not affect gas exchange or retention capabilities
  • Rated 99.9% efficient for bacteria and viruses. Restricts microorganisms while allowing H2O and CO2 to pass through the membrane
  • Prevents aerosol formation. Suitable for growth of infectious microorganisms
