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.
