Test Tube Rack 4 Pack for 15 mL Conical Centrifuge Tubes, 12 Well Stands

Four open frame benchtop racks, one in each color: Red, White, Blue, and Yellow, so every project, user, or workstation gets its own. Each rack holds twelve 15 mL conical centrifuge tubes upright and visible in a compact 4.5 x 3.5 x 2.5 inch footprint, weighing just 2.8 ounces. Designed and manufactured to order in the USA by DC Additive Pros in tough polymer. All four arrive fully assembled and ready to use.

Measured specifications, per rack

Every number below was taken with calipers on a finished rack, not estimated from a drawing.

• 12 wells, 18.44 mm each, sized for the industry standard 17 mm conical tube (17 x 120 mm) and accepting tubes, vials, and dropper bottles up to 18 mm
• Two-point tube support: each tube is guided by the deck ring and a centering pocket in the base, set 50 mm apart, so tubes stand upright instead of leaning
• A drain hole under every well lets rinse water and condensation pass through instead of pooling, so the rack dries between uses
• Open sides keep tube labels and volume graduations visible without lifting a tube out
• Comes apart in seconds: the press fit deck, base, and side panels pull apart for cleaning or flat storage and press back together by hand, no tools or hardware
• Each rack 111 x 92 x 63 mm, 2.8 oz
• Wipes clean with isopropyl alcohol or warm soapy water. Not autoclavable.

Built for research and teaching labs, veterinary clinics, mobile phlebotomy kits, peptide and reagent work, and classroom science. Compatible with the industry standard 17 x 120 mm conical centrifuge tube sold by all major laboratory brands. Made to order in the USA. Tubes not included.
