Claim Text:
1. A system coupled to a negative pressure source for use transferring plant tissue explants from a first container having a first nutrient medium substrate adapted to provide nutrients to the tissue explants to a second container having a second nutrient medium substrate adapted to provide nutrients to the plant tissue explants, the system comprising: a flexible fluid conduit having a first end adapted to be coupled to the negative pressure source and a second end which is in fluid communication with the first end through an interior of the flexible fluid conduit; a handheld pen shaped instrument coupled to the second end of the flexible conduit, the handheld pen shaped instrument having an interior in fluid communication with the interior of the flexible fluid conduit; and a tip member removably coupled to the handheld pen shaped instrument, the tip member having an interior in fluid communication with the interior of the handheld pen shaped instrument and a first end having an opening in fluid communication with the interior of the tip member, the opening of the first end of the tip member being smaller than the plant tissue explants to prevent the plant tissue explants from entering the interior of the tip member when a negative pressure is present in the interior of the flexible fluid conduit, the handheld pen-shaped instrument, and the tip member.
