hehe - they haven't changed much. nowadays they're plastic, and have printed labels with barcodes, but yeah - still the same thing.
this would be for small tissue samples, like for example if someone died of a suspected heart attack, they'd send sections of the blood vessels of the heart to the pathologist to be examined macro and microscopically to confirm cause of death.
These bottles are for pieces about the size of the tip of your finger, about 1cm cubed. they go right up to massive tubs for entire organs - those are creepy.
and, as a vaguely-related side-note: all histological and pathological samples taken by hopsitals in the UK must be kept for five years. the microscope slides made from those samples must be kept for 20 years. The storage rooms are huge - and phenomenally morbid - i wonder what they do with all the samples when the hospital shuts down? presumably move them to another hopsital - they legally cannot throw them away.
Yeah, that's a slops sink. a sink with a flush as well as taps.
and yeah, the high cistern is fairly typical of old British plumbing. the tiolets at my school had cisterns all the way up there. i guess it provides more gravity and more force to the water.
you don't wear your everyday white labcoat when dealing with unknowns and potentially infectious stuff [such as dead bodies] because you don't want to get splashed with something nasty in the morgue and then walk out into the general hospital and spread it around.
often they wear blue or green coats - a bit like surgeons - in the morgue and they'll be thoroughly washed after use - at work we're not allowed to take out labcoats from the site, they have to be washed onsite, so nothing gets taken out or brought in on them
