Question 4

how to use syringes to ensure more accurate measurements?

Answer 4

use appropriate sizes

• use smaller syringes for smaller volumes for greater precision
• use larger syringes for larger volumes to minimise the number of pulls which will make it easier to keep track, reducing the chances of error

when dispensing the liquid from the syringe into the beaker/test tube etc, insert the nozzle into the test tube before pushing down the plunger, reducing the chances of it spilling
