Pipette Tip Types

Pipette tips are classified into several types based on their functions and properties. Sterility is one factor that distinguishes pipettes. Some tips may be sterile and RNase-free (filter tip). Non-sterile tips, on the other hand, are typically autoclavable and useful in simple laboratory experiments such as serological tests.
Another consideration is their purpose; some require a longer head to prevent contamination (long tip), while others require precise measurement (low retention tips). Finally, size is a basis for differentiation; universal (non-sterile) pipette tips range from 0.1 to 1000 l.
