Abstract: A test device (80) for testing for the presence of a substance in a sample held on a sample carrier (30) includes a holder (82) for holding a sample carrier (30) which includes one or more chambers (50,52). The test device (80) also includes an actuator for compressing or depressurizing the chamber(s) (50,52). The actuator is configured to prevent reinflation of the chamber(s) (50,52) after compression or depressurization.

Abstract: A novel, improved plant support devise, that is universally adaptable for holding one or more plants. This planter's pot is specifically designed for placement upon the top of any 4×4 inch object. Examples of objects it is intended for mating with may include the top of fence posts and/or mailbox posts. Said planter's pot is architecturally designed with a 4×4 inch, introverted opening in the center of the base of the pot. When met with, for instance, the top of a 4×4 inch fence post, the planter's pot introverted internal cavity would mate with the pot. It would sit, combined with the 4×4 inch object. No additional attachment devices are needed to secure such planter pot to its base.
