I have too!
I rinse them with distilled water afterwards and then store them in distilled water in the fridge. Test them before they go again but mine worked fine for almost 2 years doing this - just remember to take them out the fridge before the lesson so they have time to warm back up
I'm making agar plates and realised the CLEAPSS recipe doesn't state to use distilled water for nutrient agar (unless I missed something) but it specifically says so for other types of agar. I always have used distilled, but does it matter what I use / can I use tap water?
If they're sterile they should be fine, if you store in the fridge make sure they're stored upside down so that the condensation doesn't go onto the agar. I believe plates do not have to be stored in the fridge though
What are they doing with the plates? If you need an inoculated nutrient broth...
For some reason when I downloaded them the Rosalind one wouldn't work so I had to save it a different way, they're from https://medium.com/nevertheless-podcast/stem-role-models-posters-2404424b37dd if it helps!
@MadameToad @Julie Delaney thanks, I'll try both! I don't mind paying, I'm only in my twenties and I had a pharmacist last year tell me I 'didn't need one' so that's what makes me anxious about going without an appointment/school voucher. But I live with vulnerable people and get migraines when...
@Julie Delaney just tried there and thought I got one but my local are only offering it to those who are eligible for a free flu jab, so as I don't meet the NHS criteria it wouldn't let me :( so frustrating as they have lots of slots!
Love it, that is one of my favourite shows!!!
Retail therapy is needed sometimes and it's always nice to 'treat yo self' (anyone know what show that's from?!), think I might get a nice new cosy jumper as the prep room is freeeeeezing
Honestly I find that biology practicals are all over the place - one minute it works, the next it doesn't and for no obvious reason, so try not to let it affect you too much! Most teachers don't want to admit that they don't actually know what they're doing so it's easy for them to try to blame...
