Thanks Ian. It was not a pleasant job but had to be done. I think the problem was not the maintenance staff but a power surge. Its happened before during the wet season because of the humidity and the building's wiring is ancient. I thought i had covered all bases only leaving the one fridge on, and...

I have wiped it out with vinegar, put bi carb, charcoal and vanilla essense in the fridge. The smell is slowly going away no where near as bad like monday. I guess its a matter of time. I might see about swapping the fridge over witht the one downstairs, and then i can use it for Marine Studies Diss...

Hey Rosalie,

Yeh I kept my hydrogen peroxide, I thought it may find some use. I had peptones, benzoin and other biological chemicals, will they be any good, Im thinking not.

That is very true It can only get better, I hope.

I still cant get rid of the smell, its horrid...any tips?

Hey all, Just having a little vent. Started yesterday, walked in to my prep room and there was an awful smell. I looked everywhere, then checked the fridge/freezer and it was off. I believe it had been off for quite some time as I had fruit flies having a field day, rotten meat. It was absolutely pu...

oh wow, guess hes leaving at a good time....

I can handle the humidity and heat here, but when its 44 C in Adelaide, you nearly cook to death...yuk

its a good site, glad i found it.

I haven't been to the riverland for years, nice place to unwind along the Murray. My dad said its been scorching hot down there, and he is coming to see me on Thursday, and its stinking hot here too!!

I am lucky, I have an old box full of em, but there is this company that you can purchase them from, a recycling place...

Hey all,

I have managed to find a poster holder down in our old storeroom but now I need to find the cardboard insert to hold the posters. I have found a few but have mould on them. I will have a look at Officeworks...should be able to find some.

Thanks

Dave

Hey fellow labbies.....I can almost see daylight....On holidays next Tuesday!!!! I can almost see myself sitting on Magnetic Island looking at the Barrier Reef!! Does anyone know where I can purchase a chart storage holder? I want one on wheels with the inserts for the posters. I don't want a wall o...

I wish I could get a little help sometimes. I am the only labbie here, Im 4 days a week (Get Wednesdays off) and If i am not here no one replaces me. My boss knows the labs so if someone needs anything, he has a pretty good idea. Last term i got violently sick with some sort of bird flu, I was sick ...

Does anyone know who tests/inspects fume cupboards in Cairns? I Need to get my fume cupboards checked.

Do you have to get them checked every year?

Thanks Dave

I make up about 30 plates at a time, 15 with the added bacteria and 15 normal nutrient agar (control), So they can be compared but the bateria added plates are so much better. I keep them in the fridge until they need to be used and last for up to a week or two. Once they are taken out of the fridge...

Has anyone ever added the bacteria to agar before pouring? I have been experimenting with agar and have got some awesome results. The teacher I am making them for have been teaching for well over 20 years and has said he has never had results like this, so I thought i would share my secret. I have b...

10g Agar
2.5g Bonox
1.5 Peptone
500ml Hot water

Makes about 30 plates.

I also make plates with the bacteria in the gel, allow the agar to cool to 50C then add bacteria (rhodospirillum works a treat) give it a mix. Alot better then onnoculating.

I get that too, when I say I work in a school, they automatically say "oh you get lots of holidays" and I reply, I wish I worked more because everytime the holidays come around, I can't do anything or go anywhere because I dont get paid. Sometimes I have to go a month without money, its no...

I work 28 hours a week with 35 science classes a week in 5 labs. We have about 750+ students and I dont work holidays. I am not sure how to work it out but i can tell you, I struggle and when I get teachers complaining, I don't let it worry me because I am not full time. If they complain hard enough...

Cairns is a beautiful place but a bit backwards, alot of things don't make sense, but it is a tourist town afterall and everyone lets there hair down. I came to Cairns for a working holiday and after a week, i said there is no way I am going back to Adelaide. I love visiting and seeing family friend...

I live just down the road from where that croc took the dog...very scary stuff!!!! I don't go walking around creeks in my area. Theres crocs everywhere in Cairns, they had one near a drain on Mulgrave road once whcih is right near the city. Their numbers are large and there always stalking the beach...
