The photo shows good-sized stir-bars, but in actuality, the LARGEST one was 1/4"! From the picture, I assumed the largest was 2". Be sure you want test-tube-sized stir bars!!

Tiny stir bars perfect for spinning 0.2 - 2.0 mL reactions in small tubes. Spinpack product works perfectly well. Supplier provides clear dimensions "Contains six stir bars, two each in the following sizes: 0.315 x 0.059" (8 x 1.5 mm), 0.276 x 0.079" (7 x 2 mm), 0.394 x 0.1184" (10 x 3 mm)". Use a ruler to check if these are a good fit for your application.

Title says it all. There's not much else to say. Good construction, standard packaging, and they spin like the aught to.

Excellent quality, built to last. I use these with a small VWR stirrer in a commercial R&D lab and they work great.
