7mL Clear Plastic Vials with Secure White Screw Caps - Package of 10

These vials are excellent for scintillation counting as they have a low background count and are clear enough for specimen viewing and fill checking. They hold up to 7ml and have a dimpled bottom for use with filter paper counting. They are also very good for all types of sample preparation and storage. The vials are strong enough for storage in your coldest freezer. The white threaded caps have a specially designed threading. It is only a half turn from full, sealed closure to cap removal. This makes it much easier for use, especially when you have many samples to do.
