These non-sterile 1/4cc or 1/2cc straws that have no wick and powder. These straws are used primarily as labeling straws that are often combined with 1/4cc to 1/2cc connection straw adapters to identify straws without removing them from their cryogenic canisters. Another popular use is as a 5" syringe extension when used with the syringe-to-straw adapter to draw up fluids from bottles or collection vessels, or even 'as-is' to pipette small samples to slides. Packaged in 100/pk or bulk 2,000/pk.
