Ours is on a timer which comes on about 7am - til 6pm. However, what do people do about flammable cupboards etc? It is located inside the chemical store but when I open the door to the flammable cupboard I am just about knocked over backwards from the fumes!

Thanks. I will have a look at their website.

Prima, could you please tell me about the Pasco probe - is it an independent unit or does it have to connect to a data logger? Could you please tell me where you purchased it from and the price?
Thanks

Sorry I had not realised I can not put those web addresses up. I don't seem to be able to insert a picture so I have added an attachment. If anyone has experience with any of these could you please let me know what you think.

Hi Bigmack. Have you had a chance to decide if you want them?

Does anyone use a face mask or respirator when dealing with organics? I seem to be especially sensitive to them and even with decanting them in the fume cupboard and using gloves, I develop a headache very quickly and yesterday felt quite nauseous. I would like better protection before I use them ag...

Would love to know where you purchase your preferred variety. If you are not allowed to put the company name up here could you please PM me. Some types definitely fall to pieces very quickly and it wastes a lot of time repairing them.

Hi Would any of you people who are clever with repairs be interested in an old Ohaus balance or an oscilloscope? I have been advised that the cost to repair them is not worth it, however I am reluctant to just toss them. If you were interested in fiddling with them to see if you can get them working...
