A 12 ounce (360 ml) plastic collection bottle equipped with a semen filter sock and ported coupling cap. This is the bottle and filter assembly used in the complete collection kits but without the AV liner. This would be used as a component part for those who assemble their own kits. Collection bottles have a 38mm/1.5" opening.
Many breeders like to assemble their own kits, mix and match components, or reuse certain components, so they'll get their supplies separately. Semen collection coponents range from filters to liners to bottles.
