General description

The Scienceware vacuum desiccator has a unique shape which offers maximum interior clearances for more or larger contents without crowding the benchtop. The thick walls ensure a rugged shatter resistant unit that simply stores a vacuum or stays sealed even if not under vacuum. The polypropylene stopcock (PTFE plug) which is included has a vivid, red handle and a hose connection that accepts 1/4 in. (6.4 mm) I.D. vacuum tubing.

The top section can be lifted off using the large ribbed knob at the top center. A neoprene O-ring offers a secure seal, which does not require grease, but is unaffected if grease is applied. A rigid, perforated polypropylene plate, 1/8 in. (3.2 mm) thick is removable and supports the contents, leaving space underneath for desiccant backup if desired.

  • Small footprint with 13% more interior volume than typical desiccator domes
  • Glass transparent, shatter resistant polycarbonate upper section offers unobstructed viewing of contents
  • Polypropylene lower section has excellent chemical resistance and can be used with incandescent crucibles supported on porcelain plate
  • Polypropylene stopcock with PTFE plug controls airflow to gently release vacuum
  • Holds a vacuum of 29.9 in. (759 mm) Hg for 24 hours at room temperature without need for vacuum grease
  • Not compatible with organic solvents and vapors
  • Parts are autoclavable at 121ºC for 20 minutes at 15 psi. All parts that have vacuum grease must have grease reapplied. (Stopcock)

Anti-prion protein (PrP) monoclonal antibody 132, which recognizes mouse PrP amino acids 119-127, enables us to reliably detect abnormal isoform prion protein (PrPSc) in cells or frozen tissue sections by immunofluorescence assay, although treatment with guanidinium salts is a prerequisite.
