Frequently Asked Questions
What tube diameter does this rack accept?
This rack is designed for 13 mm diameter test tubes and culture tubes. It is not intended for larger formats such as 16 mm or 18 mm tubes.
Does the rack arrive assembled and ready to use?
No — each rack ships unassembled. This format reduces shipping volume and makes flat storage practical. Assembly requires no tools and takes only moments before the rack is ready for bench use.
Can these racks be autoclaved for reuse?
Yes. Polypropylene copolymer is autoclave-compatible, making these racks suitable for reusable applications where steam sterilization or chemical disinfection between runs is required.
Is this rack suitable for regulated clinical laboratories?
Yes. The racks are lot-numbered for traceability, manufactured from BPA-free and phthalate-free resin, and are compatible with CAP-, CLIA-, and ISO 15189-accredited workflow documentation requirements.
