PCR Tube Racks for Organized Sample Handling
PCR tube racks are polypropylene holders designed to organise, store, and support 0.2 mL individual PCR tubes and 8-strip tubes in a standard 96-well (8×12) array during reaction setup, thermal cycling preparation, and post-PCR processing. Features include alphanumeric well identification, autoclavable construction, translucent or colour-coded lids, and compatibility with 8-strip and individual tubes.
MBP Inc. supplies PCR tube racks alongside the full PCR Tubes range across the USA and Canada, with Quick Order and PO purchasing for research institutions. Request a quote today by contacting customerservice@mbpinc.net
PCR Tube Racks
What Are PCR Tube Racks?
PCR tube racks are polypropylene holders that maintain 0.2 mL PCR tubes and strip tubes in a stable 8×12 (96-position) upright array during reaction setup, pre-PCR storage, and post-amplification handling. They stabilise tubes during multichannel pipetting, prevent tip deflection when dispensing with an 8-channel pipette, and serve as organisational tools for pre- and post-PCR sample management. Most racks accept both individual 0.2 mL tubes and 8-strip or 12-strip tubes in the same 96-well footprint.

How to Choose PCR Tube Racks
Well Diameter and Tube Compatibility
Standard 96-well PCR racks have a 5.2 mm well diameter, compatible with most 0.2 mL thin-wall PCR tubes from Globe Scientific, Nest Scientific, Axygen/Corning, Eppendorf, and equivalent brands. Confirm the collar diameter of your specific tube brand before ordering if using non-standard tube geometry.
Lid: Hinged Flat vs Translucent Cover vs No Lid
Hinged flat lids lie flush when open for unobstructed pipette access; the lid can be closed to protect tubes during incubation or transport. Translucent polycarbonate lids allow visual sample inspection without lid removal — useful for barcode readers that scan through the cover. Lidless racks are the simplest format for bench use, where brief sample exposure is acceptable.
Colour Coding
Racks are available in single colours (blue, green, pink, yellow, orange) and assorted multi-colour packs. Colour-coded racks help segregate pre-PCR and post-PCR samples, reducing cross-contamination risk in labs without fully separated pre/post-PCR workspaces.
Autoclavability
Polypropylene PCR tube racks are autoclavable at 121°C (250°F) for sterilisation between use cycles. Polycarbonate lids withstand repeated autoclave cycles at standard sterilisation conditions.
SBS Footprint for Automation
Select PCR strip racks with an SBS/SLAS-compliant footprint (127.76 × 85.47 mm) to enable use with robotic liquid handlers and automated workstations when processing strip tubes on automation platforms.
Specifications Context
Standard 96-well PCR tube racks measure approximately 130 × 98 × 33 mm (L × W × H) with 5.2 mm well diameter and 9 mm well spacing. Polypropylene construction is chemical-resistant and autoclavable at 121°C. Alphanumeric embossed grid (A–H rows, 1–12 columns) matches the labelling of PCR plates and plates for straightforward sample mapping. SP Bel-Art 96-well PCR racks and equivalent formats from Heathrow Scientific and Globe Scientific are widely distributed in North American research labs.
