Heirloom Indestrucible Stainless Steel Test Tube Racks

Description

These are indestructible stainless steel racks. These racks are 40 years old and there is no evidence of damage despite heavy usage and storage in water baths, freezers, and refrigerators.  These are an heirlooms that you will pass on.  I am not joking.  They were made with unusually high quality stainless steel by special order designed not to deteriorate in water.  Sorry the company is out of the business now so I cannot tell manufacturer.  Spend the money for these and they are forever and can be passed to the next generation of scientist.  There are two sizes: four large 6 x 12 array, 2.5 xm holes and seven small 6 x 12 arrays with 1.7 cm holes.
