Designed to be used as a work or storage rack for a variety of pre- and post-PCR sample processing applications, our PCR Tube Rack works with other manufacturers' trays or retainer sets of cycle plates, individual tubes, and with eight or twelve-tube strips. Formatted in the standard 8 x 12 microtiter format and alphanumerically indexed, the rack provides convenient and error-free tube identification and comes with a clear lid with a stacking lip for easier stacking.
