Dissection blocks
How does everyone clean wax dissecting blocks?
Do you clean them with disinfectant, remelt them, or something else?
Thanks

Re: Dissection blocks
We don't have wax blocks......the kids get large shallow plastic trays for dissections, & they go in the dishwasher for a good hot wash.

Re: Dissection blocks
Don't use them. I have used either cardboard or even large polystyrene trays from Coles, so that it's all chuck-able afterwards.
Peroxide would probably work - it would lift the left over proteins (blood) and sterilize at the same time.

Re: Dissection blocks
we have the old home eco plastic chopping boards, can go in the dishwasher, or wash by hand with cold water, then scrub with bleach then rinse. cant stick pins in them though

Re: Dissection blocks
I presume you put a sample in block of wax then slice with microtome knife drop shaving on surface of hot water till wax melts then fish out sample slice to put on slide.
I would just chop out sample than add wax to crucible for recycling

Re: Dissection blocks
I have stainless steel trays with wax in them. I pour bleach to cover the surface after use then wash later with warm soapy water. When the surface becomes too chopped up I remelt the wax in the tray on a hotplate. Usually it stinks. Am checking into alternatives to use instead.

Re: Dissection blocks
Sorry haven't heard of wax blocks for dissecting. I have changed to paper plates for dissections.
Re: Dissection blocks
Thanks all. The polystyrene tray idea sounds like a goer, as you can pin out the rats and then chuck them, tray and all.I had been cleaning with disinfectant and hot soapy water; and remelted when they got chopped up. As Lyn says it stinks the place out, even with good ventilation.
Thanks again.
Thanks again.

Re: Dissection blocks
What are people currently using for dissection trays? We have a heap of ice cream container lids but the bio teacher has requested actual dissection trays. Upon searching, I can only find the wax ones. I've never used those before. At my previous school we had shallow grey trays but I must be using all the wrong search terms because I can't find them. (I will keep looking because usually after I post a question like this it pops up in my next attempt at searching! ). We don't have a massive budget but I'm happy to spend a bit on something that's a little bit more sciencey-looking!

Re: Dissection blocks
We had those Grey shallow trays at old school to Rosalie .
Apparently they were Photographic development trays .
I couldn't find the original ones for Love nor Money but I did find some Newer ones .They all had a small pourer on one corner . I thought they looked strange but the Bio teacher said it was great for pouring the blood down the sink

Re: Dissection blocks
Hi Rosalie
I just purchased dissection trays from Haines ($24 ea) and they are great. Teachers happy with them. Prior to that we used plastic chopping boards from Woolies.

Re: Dissection blocks
I bought the thin chopping board style from Haines. They come in a pack of 10. Easy to put in the dishwasher. Some of the smarter teachers got the kids to put the boards down first, then newspaper on top - made for a much easier clean up.

Re: Dissection blocks
Probably because it was a link to an external company... sorry! I'm pretty sure I'm going with the photography trays now anyway.Wayne wrote: ↑30 Aug 2024, 11:12Says, "The requested topic does not exist"RosalieL wrote: ↑28 Aug 2024, 12:49 viewtopic.php?f=26&t=451/tech-tray-with-mat.html this one (if the link works)?

I honestly couldn't remember if I had or not ,so I just contacted Briony at my old school and she says she has had no issues at all with putting them through the Dishwasher .
