Cap Mats

Cap mats or sealing mats from Specialty Silicone Products (SSP) protect the wells that store samples for analytical research or laboratory testing. They’re used with microplates, plate-like devices that contain wells arranged in a rectangular matrix. Each well serves as a vial or test tube for an individual sample. At SSP, we use a proprietary silicone rubber to produce a precision-molded cap mat. 

SSP supplies cap mats that are made from a platinum-catalyzed, premium-grade silicone that’s been conditioned for low bleed. We also supply plate covers that are made from other polymers. The wells in these standard mats can be either square or round. The round wells have plugs that are either 7mm or 8mm in diameter. 

SSP also supplies standard cap mats for 384-well microplates for high-throughput, low volume screenings. Like 96-well microplates, these laboratory products support the use of robotics, automation, and liquid handling systems. Applications include sample collection, bacterial and yeast growth, cellular analysis, and luminescent and fluorescent assays. 

Cap mats from SSP are also available in custom configurations. We can create custom molds that meet challenging requirements for custom designs and colors. SSP has an in-house, on-site machine shop that designs, builds, and maintains all our molds. This significantly reduces lead time and costs for a new mold.  

See the product tables below for more information about standard cap mats from SSP. If you need custom sealing mats instead, click any of the Custom Septa buttons below. All our septa is Made in the USA at our Ballston Spa, New York facility. We use precision molding equipment, platinum catalyzed silicones, and other quality materials.
