Multiwell plates



> Multiwell plates

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



> Adapter collars for biomek 2000

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



> BugStopper microplate capmat

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

> UniVac 1 vacuum to waste manifold

UniVac™ vacuum manifolds
UniVac™ 1 Vacuum to Waste Manifold
The Whatman UniVac 1 is a single station unit that can be used for evacuating all liquid from a filter plate to waste, when the filtrate is not required for further analysis.

UniVac 3 Vacuum to Collect Manifold
The Whatman UniVac 3 is a universal filter/collection manifold designed to hold all the UNIPLATE™ formats from 100 µL to 10 mL.



> UniVac 3 Vacuum to Collect Manifold

The specially designed drip directors beneath the UNIFILTER® plate ensure that the filtrate is directed into the corresponding well of the receiving UNIPLATE. The UniVac 3 comes complete with vacuum gauge, regulator and two-way control valve.
