Safety-Multifly® winged needles are pre-assembled with a multi-adapter for a secure connection to S-Monovette® blood collection tubes. The needle safety device can be activated with one hand to reduce the risk of exposure to bloodborne pathogens through accidental needlesticks. The assembled Multi-Adapter is engineered to prevent contact with the back needle. Safety-Multifly® winged needles are available in two gauges and two tubing lengths. Individually wrapped and sterile.
