--Two sampling methods: Preset Type / Pumping Type
--The syringe plunger is made of anti-tear, high-elastic ventilated silicon membrane, which ensures its excellent sliding performance and reduce the leakage at the same time.
--The unique build-in ventilated plunger could expel the residual air automatically, then self-seal when touching with blood so that the blood sample could be sealed effectively.
--The special technique of heparin coating inside the syringe ensures the sufficient mixture of heparin and blood, providing more accurate result.
--The sealing cap design could seal the sampler completely, totally avoid test error caused by the mixed air, and provide better condition for sample' s storage and transportation
