Gelatin capsule vials provide a convenient, inexpensive means of storing small or brittle insects. Some kinds of small insects may even be reared successfully in these disposable capsules. For temporary or permanent storage, capsules, along with data labels, may be pinned through one end with a standard insect pin. Capsule vials are translucent, approx. 7.5 x 20mm; size 0 (8 grains).
