J which area are you in please.

The Wheatstone bridge is an electrical bridge circuit used to measure resistance. It consists of a common source of electrical current (such as a battery) and a galvanometer or a multimeter that connects two parallel branches, containing four resistors, three of which are known.

Your SDS should tell you. But it needs to go to chemical waste collection. In a jar or container well labeled.

Marama T I also had to goggle that one. Very interesting indeed.

Hi Kimmy68 I do not think there is any thing on that, I would be very interested if there is. The DoE put out the CSIS and the teachers should do a RA in there head. I agree with new teachers we need something.

My feeling is to get in touch with the place your purchased the item from. Sorry I know not much help.

Oxalic acid ONE OF THE BEST, my first port of call

What is the difference between Class A and B volumetric flask? The main difference between Class A and Class B glassware is their manufacturing materials. Class A is made of strong borosilicate material, while Class B is made from soda-lime material, which makes Class A glassware superior for chemic...

Guess it did;nt come with a SDS? Phone the people she brought it from.

What is the button battery law 2022? From 22 June 2022, businesses that supply button or coin batteries, or products containing button or coin batteries, in Australia must comply with these standards. The new safety and information standards require manufacturers to: create secure compartments so ch...

I would put that Ethanol was used on the label. to cover your back, if nothing else.

The CSIS is down right now, the online one that is. So I can not check.

Thank you for tea, ha ha

Cup of tea coming up for me Bigmack?

Just checked my cupboard, and Tetley extra strong, has staples, I purchased them on Wednesday this week.

Kassh see how the plastic lids are fine but the glass one is not. Removed the glass one and go for a plastic lid.

Sodium hydroxide stock solutions should be stored in plastic containers. Glass containers should be completely avoided in the preparation and storage of sodium hydroxide solutions.

Sodium hydroxide slowly reacts with glass to form sodium silicate, so glass joints and stopcocks exposed to NaOH have a tendency to "freeze". Flasks and glass-lined chemical reactors are damaged by long exposure to hot sodium hydroxide, and the glass becomes frosted. It should have a plast...
