Racks & Vessels
Racks are dedicated to 75 ml digestion vessels. The rack should be used for either quartz vessels or Teflon
®
vessel and not a mixture of each. A rack is
assembled by placing the digestion vessel in the microwave tube extender and placing the bottom of the digestion vessel or Teflon
®
sleeve support on
the tube support on the bottom or the rack. The safety pressure cap is tightened by hand until the bottom of the Safety Pressure Cap is snug against the
top of the plunger liner.
Never use a quartz or a quartz Teflon
®
vessel sleeve which appears cracked or damaged!
Excessive tightening is not required and may cause damage. Only a snug fit is required.
After weighing the sample in a quartz vessel and adding acid, place the Teflon
®
cap on top of the vessel then place the plunger liner on top of the Teflon
®
cap. The Teflon
®
cap seals on the intersection of the quartz vessel and tapered edges of the Teflon
®
cap. The Teflon
®
cap is held into place when the
Safety Pressure Cap is screwed into place.
Place the vessels in the ‘
Mini WAVE
Rack’.
Place the vessel in microwave tube
extender and place under the safety
Pressure Cap. Hold the vessel by hand
during the process.
Tighten the safety pressure cap until the
bottom of the cap is snug plus an 1/8 of a
turn. Or use the torque wrench accessory
#010-600-090 set at 14 in/lbs.
The rack needs to be aligned with the
rotating mechanism on the lid. Place
tube position 1 towards the front of the
cavity.
Tubes may vent if the
digestion
temperature is above
200 °C.
Always hold the vessel during insertion into and removal from the rack. There is a possibility that vessels may fall.
Always allow the vessels to cool prior to venting and wear appropriate eye protection and gloves prior to
performing this operation. This should only be done in a fume hood.
Remove and rinse the Teflon
®
caps with plunger liner. Using the vessel volume calibration lines, samples
can be normalized directly in the vessel.
