Hi All, I have a DELTA water still, from LABGLASS... This is an expensive bit of gear but this is one that I requested that we buy and I never look back. Just google Delta from Labglass and go from there. You won't be disappointed but YES you do pay for what you get. This is top of the range. Cheers...

Hi Girls,

Wishing I were there.

Hi All,

Trish, I have not received any correspondence regarding any Post Mac. conferences here on the Central Coast.

Sorry,

Hi All,

Ummmm, It's a trade secret...

Hi All, ri is on the money, the Pot. Permanganate is used in incendries where they inject Glycerol into ping pong balls filled with the Pot. Permanganate and they simply drop them from helicopters. (Dont want to forget which oine you filled otherwise it will be a quick landing). I'm not going to com...

Hi All,

Strontium Sulfate.

Hi All/Joy. The best option for this mixture is to discard this into sewage waste. This may sound drastic but for this mixture this will no doubt cause a fire.... The safest way to dispose of this mixture is with copious amounts of water. As I said this may be a bit drastic but the safest way for al...

Hi all, Fran.... One more thing you can re-juevenate a DEAD pH PROBE by a procedure that I have listed many years ago on this forum. If you search for it you will find it, it saves a lot of grief and will have the non-responsive pH electrodes working in no time. Rinsing with distilled Water is the o...

Hi Fran, The common hole to fall into is calibration of the pH probes and in my career I have done countless calibrations and even pH electrode re-juevinations. One question.... How well do you know the concentration of the pH 4.01 solution and what compound is it. (This matters quite a lot). The th...

Hi All,

It is better to make it fresh as oxidation with natural/artificial light will cause the Permanganate to be reduced to manganate (Brown) solution rendering the solution not fit for use.

Overnight storage can be performed by storing it in the fridge.

Hi Noona, Regretfully I must inform you that my Uni Residential Schools fall into the 2 weeks that the St Mary Conference is on. This seems to happen to me every year, I will endeavour to get there sooner or later (Sooner being the better option). But my heart is with all at the conference. Regretfu...

Hi All,

I will post spome things up soon. Just need to organise myself since now I am back in the drivers seat.

Cheers,

Robb.....

Hi All, Noona I have to regretfully say that my Uni Exams fall during the times of the Conference. The whole dissapointing thing being is that there is no break for me over the last three years. I am glad to be a presenter (Space or Chem or Physics) but I just can;t commit until I know my Dates at U...

Hi All,

I will have some photos to you soon, the pervious photos I removed as the posts were old and for security reasons I had removed them. I will have some new ones for you next week as I will be organised and up to date with all things happening.

Cheers,

Robb.....

Hi All, I have had a overwhelming reply in my Private Messages for people having the opportunity to mee myself. For those people already familiar to Chemtalk in 2007 you would have seen this post along with my photos. For those poeple interested would you like to see some updated photos of me as per...

Hi All, Kathryn, Well.... I have to conceed that Biology is not my favoured subject .......but we won't go there........ but yes I have performed the electrophoresis and what works well are amino acids and the good thing about these is that we can colour them using Ninhydrin.... brilliant...... Chee...

Hi All, For those of you whom could travel to my school at Lake Munmorah, would you be interested (an this is an invitation) in coming over for an Astronomy night.... I will be inviting our yr 11 and 12 kids only, and parents for an exclusive look at the night sky during possibly late Sept early Oct...

Hi All, Just reading the previous posts and I am amazed to read what I am actually seeing. Hmmmmm....... without being rude I can't believe how people can take things into their own hands without first double checking, even in literature. Of course Chemicals DO have expiry dates. Just look at exampl...

Hi All, Just to remind you all of off topic areas, it would be better if there are any changes to post from topics like changing from certain Chemicals to another, this allows others whom have little or no experience to peruse through relevant topic areas to pinpoint the answer they require. If Copp...

Hi All,

Trish I have sent a PM to you just topping off and reiterating what I have mentioned in the past.

Cheers,

Robb.....
