Re: 0.0001M HCI
No...I Just made this up for one of my teachers experiment.. I diluted a 0.5m down to make it.. basically its about 3 drops into 999.98ml of water as i was making a Litre...the correct dosage for diluting a 0.5m is 0.2ml, but if you are making it straight from 32% HCL it is 0.009ml..Hope this helps

Antibiotic Sensitivity Testing
Morning Everyone,
My HT is looking into doing the Antibiotic Sensitivity Testing and was wondering what bacteria is the safest to use and the matching Antibiotic. Also would like to know do they come in sets ready made. Thanks

Re: Luminol
I don't know if there is any shelf life for luminol, especially in a school setting. Might be different if you're trying to track down an offender who is on the run! Once made up, it has a very short shelf life of only about two hours. I have a good recipe for detecting blood if you need it. Hi Mer...

Re: Magnets
I've found the IEC ones are quite good. I've ordered more of these and am waiting on them. Also, one of my teachers wanted a certain type of magnet and found a company, AMF Magnetics that have a huge range, although don't know the quality but suspect they may be better than some of the cheaper &quo...

Re: Wooden Test tube racks
I have slowly replaced my wooden ones that were broken and beyond repair and the plastic ones that had been melted with the metal racks that 12 or 15 test tubes from small to large. I haven't heard anything about chemical residue on the wooden ones but it would be good to hear about
