BRANDplates® microplates
Plate types and colors

Construction and shape of the plates define the different plate types

   Standard microplates  

   Standard plates are available in all formats (96-, 384- and 1536-well).
   They are manufactured out of a single piece of polymer, PS, in transparent,
   or colored white and black, and are disposable.

 

 

   Microplates with transparent bottom

   Available in 96- and 384-well formats. They are manufactured out of white or black PS,
   with a transparent bottom made of PS. In general these plates are suited for applications
   like luminescence- or fluorescence measurements, when a transparent bottom is required.
   Because of the transparent bottom, the well contents can be seen readily and the plates
   can be used to perform transmitted light measurements. Furthermore the plates can be
   examined directly under the microscope, which can be quite important especially for
   cell-based assays. The pigmented upper structure reduces the crosstalk between the
   wells during detection.

Alphanumeric Color Coding of 96-well Plates

To enable an easy identification of the surface type and to facilitate the legibility of the alphanumeric coding, most BRANDplates® microplates in the 96-well format have a color-coded embossing.

Colors of BRANDplates® microplates

The application to be performed in the plate generally determines the color of the plates used. A basic rule is: transparent for colorimetry; white for luminescence; and black for fluorescence.

Transparent

White

Black

Transparent plates are especially suited for precise optical measurements because of their excellent optical characteristics. For this reason they are used for colorimetric assays, but also find use in the fields of cell culture and storage. Transparent plates are available as standard or low volume.

White pigmented plates are optimized for luminescence measurements. Because of the white coloration, the plates show a maximum reflection of the luminescence signals and minimize well-to-well crosstalk. White plates are available in standard, low volume, or with transparent bottom.

Black pigmented plates are optimized for fluorescence measurements. The plates show a minimal auto-fluorescence because of the black pigmentation, especially in the lower wavelengths, as well as minimized crosstalk between the wells. Black plates are available as standard, low volume or with transparent bottom.
