Hi

You using the Boiling Tubes for boiling (as opposed to the medium sized test tubes)?

I only allow any boiling or heating in the larger size tubes- the med ones spit

ok Lada I hear you. I wanted instant tannin free wood. I figure then that its not going to happen overnight. I will keep changing every day and see what happens. I remember one tank I had ages ago, but in some wood that I bought from the petshop to use a hiding places for teh fish. The water was so ...

Anyone know of a way to quickly leach the brown tannins from natural wood? I have boiled and rinsed my sticks 3 times, , over 3 days- and the water is still as brown as when I first started. :-( I am buying new fish this afternoon, and they need the wood for their teeth. But I dont want a brown tank...

I'll get mine? Plasctacine?
yes please.
beats preparing pracs

Ocker, you know you want to.... and with all that time on your hands.....

I wash our towels, lab coats and cloths in the home Ec washing machine, then pop into drier afterwards.
How do you manage without a washing machine? One place I worked in didnt have a washing machine, it was stressful, and towels hanging everywhere

we dont have science focus. Anyone want to send the prac please?

Just remember, that from Jan 2012, with the new HAZ SUBS legislation, MSDS are called SDS', but the suppliers still in pracice labelled msds , UNTIL they produce their new ones before the end of the 5 year grace period. Hazardous substances and DG are now called Hazardous Chemicals. The schools Haza...

Make sure that your celery has enough leaves to allow transpiration, to draw water up. Can use red food colouring if you have no eosin.
Place the celeryin the dye water out in the lab, with cutting boards. scalpels or razors or hand microtomes. the teachers and studetns are to cut it themselves

Thanks Rosalie

I found an instrcution page and seems its a filter wool pad

yes for sure at that price they should gold plated!
what type of hardware store material does your hubby use? these are large white pads, like rigid filter wool, but kind o f woven , not loose -IF i remember correctly

I have an Aqua One 2700 water pump that s ervices a 5 foot long tank. Works really well. However, its been running for 12 mths now non stop, and was told upon purchase that I need to replace the pads every 9-12 mths, or when water quality begins to fail. Water quality still good, but been over 12 mt...

I have a central point for the sand bucket, that being the "Spills Kit" corner. Makes a good barrier to stop spilled liquids from running, as well as can be used to smother small fires. Since they are kept in the prep room area and out of student reach, they dont accumulate rubbish. Also v...

Thanks everyone for all you help. This is SO helpful

Hi Narelle If you want a pure culture of euglena, you can buy from a bio supply company. But if you dont mind some microbeast cousins in there :crazy: , you can just chuck out the old infusion, and start afresh with new hay infusions. I find manure with a bit of straw or hay in it a very helpul edit...

Thanks Ocker
