Microplates are manufactured from Clear Choice virgin polypropylene resin. They are produced with uniform external dimensions and tolerances to meet ANSI recommendations for compatibility with equipment and robotics. These plates are biologically inert, exhibit low binding characteristics, offer high temperature tolerance (–196 to 121°C/–321 to 250°F), and are resistant to many standard laboratory chemicals. Black plates are ideal for fluorescence polarization. Microplates feature alphanumerically coded wells with round, conical, or flat bottoms. Chimney well plates feature a chimney-like arrangement in which each well stands on its own to reduce the possibility of cross-contamination, and feature individual rims that rise above the surface of the plate to aid in sealing by cap mat, thermal sealer, or adhesive sealer. Stackable and autoclavable. Plates are supplied without lids. Dimensions: 128Lx86Wx15Hmm. Plates are free of detectable RNase, DNase, human DNA, and pyrogens. All plates have a footprint conforming to the ANSI/SBS 1-2004 Standard.
