One of the best auto lancets for microscopists. Spring loaded, lancet retracts back into body of device after use for safety. Disposable.
The Unistik 2 Extra provides a deeper poke for tougher, thicker skin or for a more more generous sample.
The Unistik 2 series is the only lancet in the market that you can actually reset the spring. Sometimes a person will move their finger just as you press the release. Instead of having a perfectly good unused lancet go to waste, here you can re-cock it for the individual you were using it with.
