Half Area microplates are compatible with the same pipetting, dispensing, and reading devices you use for standard 96-well plates. The wells retain the standard 9 mm spacing, but are smaller in diameter to conserve samples and reagents. Tissue culture treated plates have chimney wells for decreased risks of cross-contamination. Clear bottom for distortion-free reading. RNase free, DNase free, non-pyrogenic, and free of DNA polymerase inhibitors. Radiation sterilized. Growth area per well 15 mm². Working volume per well: 15-175 µl. Includes lids.
