very near the barrel top and bottom. Consider where dies may fall. If they are dropped on Nylon
carpeting or similar materials they can quickly form holes. Protective mats may be needed.
DYNISCO POLYMER TEST recommends keeping hot piston rod and hot die in the
chamber/barrel; this precludes someone picking it up inadvertently. Be sure to hold the piston
by the top insulator.
Electrical Hazard
Your Dynisco Lab Melt Flow Indexer contains high voltage inside the housing. DO NOT remove
the housing or any part of its outer covers; there are no user serviceable parts inside. Service
should only be done by a qualified DYNISCO Service Technician. Be sure the outlet used to
power the indexer is properly grounded.
Calibration Thermometers may use Mercury
To calibrate the temperature on the indexer, a thermometer containing about 8 grams of mercury
may be used. Every lab with mercury thermometers or equipment containing mercury must be
prepared for breakage. Note that mercury exposed to air “evaporates” at room temperature,
producing an invisible, tasteless, odorless and dangerous vapor. Thermometers have been used
for decades in laboratory equipment and when used properly provide an accurate and effective
means of calibration. Keep the thermometer in a safe place where it will not be crushed or
otherwise broken. When using the thermometer be careful not to drop or bend the glass. Place
a hot thermometer onto cotton patches to cool. Never put a hot thermometer in contact with cold
metal or cold solvent because the thermal shock can crack or shatter the glass. Mercury is
extremely toxic and should be handled accordingly.
A material safety data sheet (MSDS) for mercury (Hg) can be found on the Internet. Observe
local, state and federal hazardous waste disposal laws when disposing of any broken
thermometers. If packaged in a sealed plastic container and labeled with the following symbol:
Broken thermometers and their spilled mercury can be sent back to the manufacturer.
UPS will accept these packages provided they are labeled and the material is in a secure
container. See Princo support vendor for address information.
