Frequently Asked Questions
How do the racks link together?
Each rack features four-way interlocking edges, so units connect along any side. Build rows, blocks, or custom layouts to match a given workflow, then separate them when reconfiguring.
Are the racks autoclavable?
Yes. Polypropylene construction tolerates standard autoclave cycles, making these racks suitable for sterilizing empty tubes or decontaminating the racks between batches.
What colors are included in a pack?
One pack contains four racks — red, yellow, blue, and green — enabling immediate color-coded sorting without ordering separate SKUs.
What tube sizes fit these square racks?
The square-well format accommodates common laboratory tubes used in benchtop sorting and staging. Confirm exact well dimensions against your tube diameter before ordering; our team can verify fit.
