Globe Scientific TUFFBLOK Rectangular Tube Rack with Lids (456950AST) adds snap-on lid protection to the TUFFBLOK linkable multi-tube system. The rectangular format holds four tube sizes — microcentrifuge, 12/13mm, 15/17mm, and 50mL — with individual lids for each section. Close the section you are not using to protect tubes from aerosol contamination, dust, and accidental dislodgement. Links together with other TUFFBLOK racks to form custom workstations.
Per-Section Lids for Selective Access
Open the microcentrifuge section while keeping the 50mL section closed. Only the tubes you are actively working with are exposed. During transport between labs, all four lids snap closed to prevent tube loss and cross-contamination. This selective access is critical inside biosafety cabinets where minimizing open-container time reduces aerosol exposure risk.
