SpeedStreaks^™ disposable inoculating loops are available in several styles and are color coded for convenience. The 1ul and 10 µl loops, each come in two different rigidities, rigid-hard, or flexible-soft, to fit a variety of streaking preferences. An inoculating needle is also available formed in the rigid-hard plastic. The loops are manufactured using a process that smoothes the edges, free of plastic burrs and will not gouge the agar surface. The loops are free from coatings and electrostatic charges that might interfere with wetting and transfer of the volume contained in the loop. The 1ul and 10 µl loops are calibrated and each box of 1000 loops comes shipped with a Certificate of Calibration that authenticates the accuracy of the loops. The loops are certified to deliver a volume within 20% of their stated volume. The loops are certified using the Colorimetric Evans Blue Dye Procedure.
