96 well cap 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 elastomer to produce a precision-molded cap mat. 

SSP supplies cap mats that are made from a platinum-catalyzed, premium-grade, FDA compliant silicone elastomer. For applications where an analytically pure mat is required, we offer an Ultra Low Bleed mat that has been specifically formulated to have minimum siloxane peaks that can interfere with results.

Our mat offering includes mats that have either round or square plugs. Our 96 round mats have two different diameter plugs; 7mm or 8mm. The 7mm diameter plug mats are typically used with plates that hold samples over 1ml. The 8mm diameter plug mats are shallow and are typically used with plates that hold less than 1ml.

All of our silicone cap mats are also offered with a cross slit for easy access through the plug by the pipette or syringe.

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. All our cap mats are made in the USA at our Ballston Spa, New York facility.
