Hold a full run of test, culture or FACS tubes upright—then autoclave the rack.
MTC Bio test tube racks are heavy-duty polypropylene workstations for 12–17 mm tubes. Choose R1115 for 90 tubes 12–14 mm in diameter or R1117 for 60 tubes 15–17 mm in diameter. Each pack contains five flat-packed racks that snap together, with molded alphanumeric grids for sample tracking.

Why Labs Choose MTC Bio Test Tube Racks
Sized by diameter
Two well sizes cover 12–14 mm and 15–17 mm tubes.
Alphanumeric grid
Molded row and column markings help you locate samples.
Water-bath ready
MTC states the racks can be used in water baths without floating.
Autoclavable PP
Heavy-duty polypropylene ships flat and snaps together.
Which Test Tube Rack Do I Need?
12–14 mm tubes: R1115
90 places in 6 rows of 15. Use for 12 × 75 mm FACS and culture tubes and 12–13 mm test tubes.
15–17 mm tubes: R1117
60 places in 5 rows of 12. Use for 16 mm culture and transport tubes and other 15–17 mm tubes.
Microtubes or conicals?
For 0.2–2.0 mL microtubes or 15/50 mL conical racks, see MTC Bio storage racks and boxes.
Flat-Pack Racks That Build a Sturdy Workstation
The racks ship flat to save space, then snap together into a rigid rack. Molded alphanumeric markings along the sides give each position a reference, so you can map samples to a worksheet. The polypropylene construction is autoclavable, and MTC Bio states the racks stay in place in a water bath rather than floating.
Typical Applications
- Holding test tubes and culture tubes during bench processing
- Organizing 12 × 75 mm FACS tubes before flow cytometry
- Water-bath incubation of tubes within the rated diameter range
- Staging transport tubes and large cryogenic vials for labeling
Confirm material compatibility and your method’s requirements before use. No additional performance or regulatory certification is implied.
Practical Bench Tip
Match the rack to the tube’s outside diameter, not its nominal volume. Confirm that tall or conical-bottom tubes seat securely before loading a full rack into a water bath.

Frequently Asked Questions
Are these an alternative to Nalgene Unwire test tube racks?
They serve the same job with different specifications. Thermo Scientific Nalgene Unwire polypropylene racks 5976-0013 (13 mm) and 5976-0016 (16 mm) hold 72 tubes in a 6 × 12 array, are molded in one piece and are stated by Thermo Fisher to be not autoclavable. MTC Bio R1115 holds 90 tubes 12–14 mm and R1117 holds 60 tubes 15–17 mm; both snap together from a flat pack and are autoclavable. Position count and footprint differ, so do not assume an identical layout. Trademarks belong to their respective owners; comparison does not imply endorsement, affiliation or common manufacturing origin.
Can R1115 replace a Nalgene 13 mm rack such as 5976-0013?
For 12–14 mm tubes, R1115 can serve the same purpose with 90 positions instead of 72. It is not identical: the footprint and array differ (6 × 15 versus 6 × 12), and R1115 is autoclavable while the Nalgene polypropylene Unwire rack is not. Check bench space and any automation or labeling layout before switching. Trademarks belong to their respective owners; comparison does not imply endorsement, affiliation or common manufacturing origin.
Which rack fits 12 × 75 mm FACS or culture tubes?
R1115. It accepts tubes 12–14 mm in diameter, which covers 12 × 75 mm FACS tubes and 12–13 mm test and culture tubes.
Which rack fits 16 × 100 mm tubes?
R1117. It accepts tubes 15–17 mm in diameter, including 16 × 100 mm culture and transport tubes.
Can I autoclave these racks?
Yes. MTC Bio specifies autoclavable polypropylene for both R1115 and R1117. Follow your facility’s validated autoclave cycle.
Will the racks float in a water bath?
MTC Bio states the racks can be used safely in water baths without floating. Confirm stability with your tube load and water level.
How many racks come in a pack, and are they assembled?
Each catalog number is a pack of five racks. They ship flat and snap together.
What are the dimensions of R1115 and R1117?
R1115 measures 247 × 105 × 63 mm and R1117 measures 245 × 110 × 72 mm (L × W × H).
