Turning the rack to one side will slant tubes 5° to produce a large surface area useful for aerobic cultures.

• Polypropylene construction
• Autoclavable
• Cannot be stacked
• Slant rack design reduces surface area

Turning to the other side will slant tubes 20° for a smaller surface area, which is ideal for anaerobic cultures and reduces the drying out of media during storage. Media-filled tubes are autoclaved with the rack in an upright position. While media is still hot, tilt the rack to the desired angle and allow media to harden. Rack can be used for incubating tissue cultures or submersion in a water bath. Choose from 13–16 mm or 16–20 mm tube openings in 40 numbered and lettered places. Not stackable.
