ISS Science for Everyone

Science Objectives for Everyone
The Portable Glovebox (PGB) was developed for the European Space Agency for use on the International Space Station (ISS); it can be transported around ISS and used in any laboratory module. The PGB confines accidental spillage of materials and helps prevent contamination of biological materials when the experiment containers are opened for observations, sampling, and fixations.

    Facility Description

    Facility Overview

    • The Portable Glovebox (PGB) confines accidental spillage of materials and helps prevent contamination of biological materials when the experiment containers are opened for observations, sampling, and fixations.


    • The PGB can be operated in the U.S. Laboratory/Destiny, Columbus Laboratory and the Russian Segment.
    The Portable Glovebox (PGB) is a multi-user facility for biological research on long-duration space flights to the International Space Station (ISS). The PGB is qualified to be used inside the U.S. Laboratory/Destiny, Columbus Laboratory and the Russian Segment. The PGB provides two levels of containment; the first level being the enclosure itself (box, gloves, filter), the second level is realized through a negative pressure of 4 mbar inside the box. Three-level containment can be achieved by placing the PGB inside the Microgravity Science Glovebox (MSG).

    The PGB has a sealed volume of 21 liters and two gloves for experiment manipulations inside. The gloves are mounted on a standard 4 inch glove ring that allows easy exchange. Different sizes of gloves can be mounted on these glove rings.

    The top, bottom and front window allow observing of the PGB activities. Both the top and bottom windows are completely removable which create an opening for experiment insertion. The front window is permanently mounted in the PGB. For future upgrades two standard 2 inch connection ports are provided on the sidewall.

    The outer dimensions of the PGB are 363 x 485 x 225 mm, with inner dimensions of 300 x 285 x 202 mm. A 28 Vdc power supply which can use EXpedite the PRocessing of Experiments to Space Station Rack (EXPRESS Rack), European Drawer Rack (EDR), User Defined Profile (UDP) Junction Box, MSG or the Russian Segment to draw power from the ISS. PGB also interfaces with bungee cord, seat track and quick disconnect brackets (camera mount) on the ISS. The standard operation of the PGB is using neoprene gloves. Then the PGB provides a single level of containment for experiment manipulation during operation. The internal volume of the PGB is about 21 liters and enclosed with respect to the environment. By using an electrical motor driven fan inside the PGB, the pressure of the working volume is lower than the cabin pressure. The enclosure is considered as one level of containment supported by the negative pressure. The PGB is particularly designed for the handling of materials in a manned environment.

    Operations

    Facility Operations

    • Crewmembers insert their hands in gloves attached directly to the facility ports. Using gloves, they can safely manipulate samples inside the sealed work area.


    • As investigations are conducted in space, the crew can see inside the PGB.
