20 mL Headspace Vial Clear Screw Top (100/pk)

20 mL, 76x23 mm. Precision-Thread vials are an alternative to crimp top headspace vials. The design allows a leak tight seal with moderate twisting force. Since they do not require crimping, samples can be taken and sealed in the field without the need for sample transfer in the lab. Vials can be used either for traditional headspace analyses or SPME. Vials have rounded bottom and 18 mm diameter necks. Packaged: 10-1/2 in. x 8-1/4 in. x 3-1/4 in. Cardboard box; Weight: 1837 g.
