Frequently Asked Questions
Are the TUFFBLOK racks autoclavable?
Yes. The polypropylene construction withstands standard steam autoclaving, allowing repeated decontamination cycles between sample sets.
How does the 4-way expandable design work?
Each rack links to adjacent units on four sides, so technicians can build wider or longer configurations on the bench without purchasing separate base hardware.
What is included in pack 456950AST?
The pack contains four racks with lids in red, yellow, blue, and green — ideal for color-coding by assay, department, or priority level.
Do the lids stay secured during transport?
Yes. The included snap lids hold tubes in place, reducing spill and contamination risk when moving racks between stations or storage areas.
