2.1.15 /U - ULTRA VIOLET LIGHT DECONTAMINATION UNIT (where
applicable)
Following is the recommended use of the /U optional feature. The information given is, to the
best of the Company’s knowledge and belief, accurate and reliable. However, no warranty,
guarantee or representation is made to its accuracy, reliability or completeness. Much will
depend upon the specimens and substances being worked on and other decontamination
procedures being used.
CAUTION: UV-C radiation is dangerous and excess exposure can cause skin and eye damage.
The germicidal lamp has a peak short wave radiation of 254nm, and combined with some
reflection from the stainless steel chamber will irradiate bacteria and viruses within the chamber,
however, any bacteria trapped in shadows or hidden pockets will not be irradiated and will
remain active.
To prevent airborne contamination in the chamber due to convection air currents caused by the
refrigeration system it is recommended that the UV system is switched on at all times the
cryostat is not being used.
The life of the 6W TUV lamp is 5000 hours, after which it should be replaced.
Open the window and press the ultra violet light decontamination unit into the window recess to
help with decontamination when the instrument is not in use. Plug the lead into the UV socket
on the control panel and switch on.
2.1.16 /Y - GLOVE PORT (where applicable)
For access to the cryostat chamber, press the glove port unit into the lower half of the window
recess and then close the window until it seals against the glove port unit.
Allows hands to access the cryostat chamber without opening the window and may be used in
conjunction with the foot switch (see above). Once glove port has been fitted, simply remove the
porthole plugs to allow access. When finished, replace porthole plugs or remove the complete
unit by reversing the procedures above.
