Practical: How to keep temperature constant?

I'm doing an experiment for my A2 coursework using temperatures ranging from 5^oC to 50^oC. They need to be heated at these particular temperatures for a period of five days. We have one water bath at college and other people will need to use it during that time at different temperatures so I won't be able to use it. Any ideas? Thanks.

The college should really have enough water baths to do it... Water bath is only thing I can think of to do it :/ What are you heating for 5 days? :L

Plants.

I was thinking of something like an aquarium heater but none of them have the range of temperatures I need.

Hmm it's a tough one... we have to keep yeast warm for a respiration experiment but our college has enough water baths to do it :smile:

I'm sure you'll find a way round the issue good luck :smile:

Fill a beaker with hot water then put whatever you need to keep warm inside it. You can maintain the temperature using the addition of cold/hot water as required. e.g. keeping yeast from denaturing put it into a test tube then keep the test tube inside the beaker full of water.

An incubator would be ideal. A waterbath is less ideal for heating for that protracted period of time.

That's no good, the OP says they need to maintain the temperature for 5 days.

So I need to do the exact same thing but with meat, is it okay if you explain how you kept a constant temperature? (If you went through with it)
Please help as soon as possible.

Thanks! :h:

use thermostatically controlled water bath
