Hi Bernard
Our M300 at the Middlesex Hospital did 20 tests on every sample, so 6000 tests per hour. I've still got the trip counter from it.

Mike,
I have not been following this, however, I wonder if Clifford Riley's
Vickers M300 has been mentioned.
This was the only large multi channel analyser ever designed and build in
the UK. It was a challenger to the Technicon systems of the 1970's. Even
by today's standards it would be considered fast at 300 samples/h (note
samples not tests). It was generally configured as a 12 channel analyser.
Somewhere, I have a photograph and the prototype is in the British Science
Museum.
The rapid increase in the workload of clinical chemistry laboratories that
started in the late 1960s / early 1970s was not only due to the introduction
of mechanised analysers but also, and most importantly, to the use of
disposable needles and syringes. New less-expensive plastic materials
allowed this to happen. With out these, often neglected devices, we would
not have seen such a rapid rise in our workload. (Previous to the use of
these disposables, glass syringes had to be washed out and boiled ready for
reuse. The needles were also sterilised and after several, uses when they
became rather blunt, they were then re-sharpened and put back in use).
Therefore, my second recommendation would be the humble disposable needle
and syringe.
Best regards,
Bernard Rocks

Subject: 50 0bjects in Pathology
ACB members may or may not be aware that the RCPath with the help of the ACB
are planning an exhibition of 50 objects that changed Pathology for next
years 50th anniversary of the College. Rather foolishly I made 2
suggestions which have been accepted and I am hoping that members might be
able to help me. The items I suggested were the early Technicon
AutoAnalysers AAI and AAII (pre SMAC) and also the early Radiometer blood
gas analysers the AstrupE50101 or the Astrup trolley. Do any of the older
members have photographs of these items in a UK (or other) lab or are
willing to share their experiences with me. Both these instruments I believe
produced revolutionary changes in the services labs provided to clinicians.
I certainly remember the AAII system in Cardiff in the early 1970s and have
vague memories of the Astrup trolley at UCH but others might have clearer
reminiscences.
I will be away between 20-27 August and may be unable to reply until after
then depending on internet access.
Thanks in advance
Mike Addison
