LABORATORY EQUIPMENT

Core Extruding Apparatus

• Paleoecological analysis
• Precise, incremental core sample extruding and sectioning

Core Extruding Apparatus Includes:

• core tube funnels
  • standard sizes fit 5.0, 7.5 and 10.0 cm outside diameter polycarbonate core tubes
  • polyethylene runway with clear polycarbonate walls; stainless steel thumb screws secures funnel to core tube
  • polycarbonate spatula
    
    
• polyethylene piston assemblies
  • adouble integral "O" ings
  • hex nut can adjust the tension of the piston assembly at any point in the tube by using the adjustment wrench on the end of the extrusion rod
    
    
• incremental extrusion rod
  • used to precisely expel short sections (1.0 cm) of sediments (1.5 m length x 2.5 cm
    diameter)
  • a polyethylene baseplate supports the core tube bottom and freely slides along the extrusion rod; the core tube is pushed down until the sediment reaches the top of the tube
    
    
• rigid polycarbonate bushings
  • (1.0 cm height) are lipped to the 2.5 cm diameter aluminum extrusion rod between the baseplate and footpad
  • sediments can be precisely expelled as bushings are removed and core tube is pushed down in 1.0 cm intervals
