The cuvette caps that shipped were NOT of the old Dynalon quality. Though the sprues on these are much larger and unevenly cut the biggest problem is that these caps LEAK when used with the plastic (both polystyrene and PMMA) cuvettes. In the image provided the two caps on the left are the old Dynalon units (which perform perfectly) while the two units on the right are what was shipped. Looks close but there are very subtle differences in size and a noticeable differences in quality. I would suggest a new a more truthful name for the product be, "402364 Polyethylene Square Cuvette Cap, 19mm Depth (Bag of 1000) - These things leak"
