12 - 18 month lab tech position in Tasmania

For those interested in a 12 - 18 month position in a Northern Tasmanian private school catering for 7-12 as a technician this may be your opportunity. I am intending to take this amount of time off beginning around May 2010 and I need a fill in. Expressions of interest to jnicholls@lcgs.tas.edu.au ...

Re: artifical blood typing

For the really tight I use this recipe. Done in spotting tiles or on slides kids look for precipitation (just tell em it like agglutination) it works fine. We use it in our forensics unit. Most of them store OK as well. The dye just makes it look a little bloodlike. Blood Test Simulation Antibody B ...

Re: Bacteria

Identifying bacteria to this level based on colony morphology may be difficult. It may be worth considering using some selective media in conjunction with morphology to get to the level of identification you require.

Re: Young's Double slit Apparatus

To make a double slit easily hold a glass slide over a candle until the slide goes black with soot. Hold two scalpel blades side by side and run across the slide. This will give you the a double line the width of a scalpel blade apart. Will work with backed razor blades as well. You can then easily ...

Focal length will be shorter in lenses with a greater curvature of the surface. In many cases the thicker ones will therefore have a shorter focal length.

I always thought the hardener was Methyl Ethyl Ketone Peroxide (MEKP)

I have always been led to beleive that it is extremely dangerous to the eyes. To the point of rapid blindness.

To all intents and purposes both the drano neat and diluted will both achieve the same pH. Give it to them diluted and dont tell them.

Re: Stock Concentrated HCl

Hi All, The sodium Hydroxide will keep for a good while, so the solution will remain fine if this is kept in HDPE bottles, otherwise it begins to attack the glass bottles it is kept in. The sodium Hydroxide doesn't break down as such as worktofish has suggested, as long as the base is kept as descr...

I work on conc HCl being 10 Molar. Makes a simple 1 in 10 dilution for 1M. I dont think your conc HCl is of a particularly standard concentration and you are loosing acid as soon as you open the bottle. Remembe that you cant make a highly accurate solution of NaOH anyway and it breaks down once mixe...

Brainiacs and magnetic cornflakes.

Has anyone tried this?? A strong magnet (probably neodynium) moved over floating cornflakes makes them move towards the magnet. The theory being that the "added iron" is magnetic. Have been asked by a staff member if this was a hoax. Short of neo magnets and hoping someone else can test th...

We do similar things with some fibre analysis. Have followed the old JJJ Ministers Malibu program and have now moved onto another prepared scenario called Who Killed Jamie Lawson. We blood test by using a range of precipitation reactions. Cheap as chips and still gives the same principles. If you wa...
