Safety Information and Warnings

Do not operate on the instrument components that form part of the work area of the TriPlus
RSH when it is in motion.
Use caution when working with any polymer tubing under pressure:
• Always wear eye protection when near pressurized polymer tubing.
• Do not use polymer tubing that has been severely stressed or kinked.
• Do not use polymer tubing, in particular no PEEK or Tefzel tubing when using
tetrahydrofuran (THF), dimethylsulfoxide (DMSO), chlorinated organic solvents,
concentrated mineral acids such as nitric, phosphoric or sulfuric acids, or any related
compounds.
Do not use vials without a sealing cap, or microtiter or deepwell plates without a plate seal.
Vapor phase from organic solvents can be hazardous and flammable. Acidic vapor phase can
cause corrosion to critical mechanical parts.
When sample vials have to undergo heating and agitation, it is important to consider the glass
quality. Use high quality glass only. Remember that depending on the application conditions,
high pressure can build up in the vial. Whenever a temperature greater than 60 °C is applied,
consider the vapor pressure of the solvent used to ensure that no excessive pressure builds up.
This is important when using a temperature above 100°C and especially at the maximum
temperature of 200 °C. Be aware that solid materials can also contain volatile compounds
such as water (humidity) which could cause build-up of excess vapor pressure.
Do not reuse headspace vials. During the process of washing the vial, micro-cracks can form
which will weaken the glass wall and increase the chances of the vial breaking.
In case of a single fault situation where the temperature control of the Agitator fails, there is
the potential danger that the device will heat up in an uncontrolled manner until it reaches
the cut-off temperature of the over temperature fuse, in this case, 240 °C. Based on this single
fault scenario, when working with flammable solvents, ensure that the solvent used has a flash
point which is 25 °C higher than the maximum potential temperature (240 °C) of the
Agitator.
When filling-up a standard reservoir or replacing a solvent such as a washing solvent, remove
the solvent reservoir bottle from the system to avoid a possible spill over the instrument.
Depending on the physical, chemical or hazardous properties of the solvent, use the
appropriate protective measures for handling.
