Versatile double-ended design enables use as a spatula, spoon, scoop, scraper, stirring rod, or policeman. The unique hollow core minimizes thermal transfer for effective collection of liquid nitrogen frozen samples. Virgin polypropylene construction is resistant to dilute acids and bases. Autoclavable.   Antistatic micro spatula features two V-shaped, sharpened tip ends and is ideal for manipulating extremely small volumes of material. Standard spatulas feature a unique spatula/spoon end and a smaller scoop end. Macro spatula is 50% larger than the standard spatula and features a spatula/spoon end and a clump-busting pick end. The long shaft of the macro spatula eases access to material in larger containers.   ECO spatulas are produced with an additive that helps promote biodegradation in the polypropylene resin. Spatulas produced using this additive were found to biodegrade an average of 20% in the first 271 days of testing.   Biodegradation rates of ECO spatulas were measured according to the ASTM D5511 test method. Tests were conducted using 48% solids content; solids content in naturally wetter landfills range from 55% to 65%, while the driest landfills may reach 93%. Actual biodegradation rates will vary in biologically-active landfills according the solids content, temperature, and moisture levels of the landfill.   Length   Color Type VWR Catalog Number Unit 14 cm (51/2") Opaque Micro, Antistatic 80081-194 Case of 7500         Pack of 300 14 cm (51/2") Opaque ECO 89233-128 Case of 7200         Pack of 300 21 cm (81/4") Blue Standard 80081-188 Case of 7500         Pack of 300 21 cm (81/4") Opaque Standard 80081-190 Case of 7500         Pack of 300 21 cm (81/4") Opaque Standard, Sterile 89097-816 Case of 500         Pack of 100 31 cm (121/4") Green Macro 80081-192 Case of 3600 VWR?
