Unusual fungi
Hi all Looking for suggestions as to what an unusual fungi might be. (Sorry I don't have a photo.) It was a dark colour but had a very metallic sheen to it. Definitely fungi and just on our normal nutrient agar. The swab was just taken from somewhere within the lab. Never seen anything like it befor...

Re: Electrophoresis Kits
We have the Hexogel Electrophoresis unit from STEM Reactor. Can run 6 gels at the same time. We have been very happy with the unit and with the service from STEM reactor. Mostly we do the candy dye extraction but once per year we get in one of the DNA simulation kits.

Re: Incubator or oven
We have ordered an new incubator for next year. Our Thermoline has given up after 20yrs service. Repair was going to cost approx $800. We had the 43L but have decided to go to the next size up, 80L. Getting a Thermoline again.

Re: iron standard solutions
Managed to find the calculations from last year - it is more complicated than just weighing out a percentage as they have to be made from combining potassium thiocyanate and iron nitrate. If anyone is interested I will put up what I am doing.

Re: Plastic dropper bottles
Where do you source your bottles from? I am finding the dropper bottles seem to now be a wider bottle which does not fit in the unitrays.

I always describe myself as a science technician - as far as I am concerned I have the qualifications and are far more than an assistant!

data loggers
Hi all We have used the Data Harvest data loggers for ever. We are needing to purchase more data loggers and we are considering biting the bullet and going with a new brand as we haven't always been happy with the data harvest. What are others using and do you like them? Thanks in advance. Kathryn :)

Risk Assessment for Lab techs
Good morning
I noticed a conversation on the ASETNSW Digest about doing RA's for preparing experiments eg diluting acids etc. I have not thought about doing this before. Apart from dilution of acids and bases what else do you make RA's for (separate from the teacher RA's for experiments)?

Re: Chemical waste bottles
I was planning on having waste bottles for organics; inorganics (cobalt,copper, strontium); lead; nickel; chromium; zinc; silver. The 2.5L Hdpe bottles chemicals come in are stable so I would not be too concerned about them tipping over if they can be used for waste storage, and if I can source them...

Re: Chemical waste bottles
Hi all Having just done my first ever chemical waste pick-up in the 15 years I have been here, I am now trying to be more conscientious with chemical disposal. I am following the advice on Science Assist. Does the wastes need to be stored in glass bottles or can some be in plastic? Where have you so...
