1 Care and Maintenance
Dust pr otection is provided by a fle xib le du st cover which
s hould alwa ys be us ed when the in s trument is not in u se. Th e
stand should be cleaned from tim e to tim e with a linen or lea-
ther c loth; alcohol must nol be used as it altacks th e pai nt , but
pe tro leum is well suited for clea ning the paint ed surfaces. Pale
spots on th e obj ec t stage c an be rem oved by ru bb ing with paraf-
fin
oi l or vaseline.
Particular ca re should be taken when undertaking s tudie s
using acids
or other aggre ss ive chemicals. Dire ct contact of
these substances with the stand or optics must be a voided
under all c ircumst ances, and all parts sh ould be carefully
cleaned a ft er u se . The optics must be kept sc rupul ously clean.
Du st ca n be removed from glass s urf aces by mea ns of a dry>
fine-haired brush, blowing gently acros s th e surfa ce whil st
brushing. If the
din is difficult to remove, a cle an cl oth , mois-
tened with distilled water , c an be u sed or , if trus also h as no
eff
ec t, p ur e al co hol may be applied . Parti cular car e should be
taken when clea ning anti~ref1ection coatings. Th e outer eye-
piece
surfaces an d the front eleme nt s of th e objectives have
coa ting s of approx imat ely the sa me hardn ess as glass and mu st
be correspondingly carefully clea ned .
Objecti ves s
hould not be screw ed apart during cleaning. If
damage or dirt is noticed ins ide th em, th ey should be re turn ed
to us for repair. Cleaning of the inn er su rf ac es of the eyepiec es
is also advi s ed against.
Micros
co pe s b ei ng used in hot and lor humid cJimat es r eq uir e
special
care . It should be ens ur ed that a build-up of fungus
do
es n ot occur, which is managed , in th e first place, by th o-
rough a
nd m et iculous cl ea ning and storag e in a cupboard
whose inside temperature is at least 5 OC above that of the
room.
It mu st al so be provided with ai ring holes, loosely
plugged with co
tton wool or ga uz e as protection aga inst dust. If
this type of st orage is not possible, the microscope mu st be
kept in a clos ed co ntainer with an ade qu ate amount of dr ying
age nt (e.g. silica ge l) . These me asures s hould be ta ken even in
laboratories
with air co nditioning . In warm and dry clima te s)
du st is the greatest ene m y. Th e ins trument should, ther efore,
be cove red with the du st cover immediat e ly after use or clean-
ing and s
tor ed in a c upboard. If a humid period of long er than
one m on th occurs, storage in a warm cu pboar d, as described
above, is d es irable.
Proper handling of the mi croscope will ensur e d ec ades of se r-
vice. If , however, a check over or repair becomes necessary,
