Laboratory Test Tube Rack Vector QR Code for Stickers

About this design

A laboratory test tube rack holds tall glass tubes filled with cyan, yellow, red and magenta liquid, set on a purple slab with a white sticker outline. The three finder squares are hidden inside the dark square frames of the rack, while the modules are carried by the dark bubbles, clips and rungs scattered across the tubes. Dark navy and plum shapes sit against pale glass and bright liquid, which keeps the pattern distinct throughout. The red tube in the center has a glossy bulb that adds a clear focal point.
