Merck, 22449, Supelpure-O Oxygen/Moisture Trap

The oxygen-removing catalysts can reduce oxygen to less than 2 ppb when the level in the incoming gas does not exceed 10 ppm. Because the catalyst is coated on a Molecular Sieve, this trap also can remove water vapor. Dimensions: •120 cc Trap: 111/8in. (28.2 cm) long x 13/8 in. (35 mm) diameter •750 cc Trap: 161/2 in. (41.9 cm) long x 25/16in. (59 mm) diameter •S-Trap: 71/2 in. (19 cm) long x 59/16 in. (14.1 cm) wide x 1/2 in. (13 mm) diameter [total bed length = 193/4 in. (50.2 cm); the extended bed length ensures prolonged contact between the gas and the adsorbent and provides greater working capacity]
