Hi all,
I have a query from a colleague doing research on neuroanatomy as to
whether
it is possible ( with relative ease) to cut 20mu sections from JB4 resin
embedded tissue? Apparently these sections ae to be stained and then used
for stereomicroscopy. My experience is not that extensive to be able to
answer her, so I would appreciate some advice here
best regards--

I would disagree as I am on my third Shandon in a long career and have
never had a problem with any of them. Age and growth in nneds got them.
Currently we use a Pathcentre and it has been excellent. If you haven't
used one it is hard to comment on how they work and how the company works
with you. I have used VIPs and they are good. It is preference and
comfort on purchasing a unit.

I have not heard much good about the Shandon processor. For reliability go
with a VIP every time. This comes from MANY years in the field. I have
never had problems with one.

Subject: Re: [Histonet] Tissue processors
To all:
Sorry to bother the list with a question that has no doubt been addressed
in the
past, but now that we are looking into possibly replacing our tissue
processor,
I would like some input. It no longer is covered by a service contract and
things are starting to go wrong with it. We have a Hypercenter XL
(ThermoShandon).
We are a core pathology lab for a research group. Typically we run @
1000-1500
paraffin blocks/year, so we are looking at a processor that would meet our
needs. We have limited space, so something, size-wise, like the
Hypercenter XL
would be required.
What do most people prefer? If you would like to contact me off-list, my
email
is below.
Thanks!

Hi All,
We have a question regarding the disposal of formaldehyde. We were told at
our hospital that a consultant said it was okay to dump formaldehyde down
the drain. I believe they said it was okay to dump 15 gallons or so a day!
We are not to fond of this idea and would like to know what everyone else
is doing. How is everyone disposing of their formaldehyde? We would be
especially interested in what other hospitals in CT are doing.

I'm in Indiana. Here, it is up to the city. We dump all of ours down the
drain and supposedly the city has ok'd that. They say that our hospital is
big enough that all of the water used here will dilute the formalin enough
to make it ok. However I had heard, back when I was in school that formalin
kills the beneficial bacteria they use at water treatment plants. So I'm
opposed to putting it down the drain. . . yet, that's how we do it here.

First ... even if the local authorities allow this ... it doesn't make
"Green" sense to do it, especially when there are other very workable
alternatives. The path we chose was to purchase a very simple gravity feed
recycler produced and sold by Creative Waste Solutions (888) 795-8300.

We are discouraged from putting most any chemical down the drain. The MWRA
(Massachusetts Water Resources Authority) monitors mercury levels, etc. in
Boston Harbor (as well as waterways throughout the state) and will issue
steep
fines if labs are found to be dumping such waste down the drain.
Consequently,
our in-house Safety Office and our outside waste management company
(Triumverate
Environmental) monitor our waste. Alcohols, stains, and fixatives are
disposed of as hazardous waste.

The same recycler is used here for us. we are absolutely not allowed to
put formaldehyde/formalin or EtOH or Xylene down the sink. If you don't
use a recycler, hire a waste company to handle it.

We dump very little down the drain. Formalin has not been drained dump
since 1988. We used to have it hauled away, because the former
administration never got into re-cycling the formalin.
What we do today, is too de-formalize the formalin, test it and then drain
dumped if it passes. We buy the de-formalizer from Surgipath. We had to get
this approved the State and we have to keep our records for 5 years. I keep
the original and send a copy to the Director of Hazard Waste.

We collect ours and the Hazardous Waste Dept of the hospital collects
it. Now what they do with it I have no idea. We collect all our waste,
fixatives, stains etc. I know of at least 2 facilities in Houston that
pour theirs down the drain.
I am from Boston I was so pleased to read the steps they have taken.
They city spent a lot of money cleaning up the harbor.

Here's a message from Jennifer....(please respond to the list or her
directly.... thanks)
Hi everyone,
We are getting ready to start running immunos at our lab and we need to
install a DI water system. After talking to a friend who recently put in a
system at his lab, I realize that there is a lot more to it than just
simply putting a hole in the wall and tapping in some DI water. Anways, we
are going to start running them by hand but, eventually want to be able to
use an automatic stainer. Since the buffers require the use of DI water
and it is recommended to it in the pressure cooker or decloaker for heat
retrieval, we definitely need to put in a system. We will most likely be
starting out running just a handful of stains but, would like to be able to
increase that number eventually. Can anyone tell me what type of water you
use (ultrapure, Cap type 2 etc), how much water (gpm), how much space in
your lab it requires, do you need a certain pressure, and any other helpful
tips?
I appreciate it. Thank you.

Hi Margaret,
You are right you can take the girl from Boston but not Boston out of
the girl. Not to be picky...Bostonian...or has it been changed :0
My entire family is there and I go visit every summer.

Betsy,
Nice to hear from a (former)Bostonite. Although, if you are from
Boston, you
are always from Boston! You are right: the city did spend a lot of
money
cleaning up the harbor and all that feeds into it. MGH is right on the
Charles
River and I'm sure I don't have to tell you how disgusting that was!
When I
first moved here in 1968 (oops, dating myself!), I went sailing with
friends on
the Charles (Community Boating). We capsized and it's a wonder we all
did not
come down with typhoid!

We collect ours and the Hazardous Waste Dept of the hospital collects
it. Now what they do with it I have no idea. We collect all our waste,
fixatives, stains etc. I know of at least 2 facilities in Houston that
pour theirs down the drain.
I am from Boston I was so pleased to read the steps they have taken.
They city spent a lot of money cleaning up the harbor.

Jessica:
It is absolutely prohibited, "verboten" to dump formalin into the sewer
system. Try to check out other recommendations by this "consultant" and
take them with, at least, a grain of salt.
That guy does not know what is talking about and could get your lab in
serious trouble.

Hi All,
We have a question regarding the disposal of formaldehyde. We were told at
our
hospital that a consultant said it was okay to dump formaldehyde down the
drain.
I believe they said it was okay to dump 15 gallons or so a day! We are not
to
fond of this idea and would like to know what everyone else is doing. How
is
everyone disposing of their formaldehyde? We would be especially interested
in
what other hospitals in CT are doing.
Thanks,
Jessica Piche-Grocki, HT(ASCP)

Kind of a "Friday" type of question inasmuch as it could open some
"cutting" remarks.......how do others handle microtome blades that are
not totally used? Our situation is that we use the more expensive
"teflon coated" blades for certain tissues that are more delicate or
difficult to obtain the most optimal sections and use the ceramic coated
blades for routine microtomy. Obviously, the techs are oftentimes going
to have a blade with an area that is still very usable and the dilemma
is a safety issue as to where to place/store blades that are not ready
to discard! Any good ideas??? Appreciate any "kind" ideas!!
Thanks.....
