[Standard requirements] The pesticide residue is distilled to 20mL. How do you do it?

This standard has strict requirements for the pre-processing and subsequent testing processes. The pretreatment process as mentioned is as follows: weigh 20 g of the thawed sample (accurate to 0.01 g) in a 250 ml stoppered conical flask, add 20 ml of water and 100 ml of acetone, homogenize for 3 min, filter the extract, and residue. The extraction was repeated once more with 50 ml of acetone, and the combined filtrate was concentrated in a 250 ml concentrated bottle and concentrated to about 20 mL in a 40 ° C water bath.

Now, do you still estimate the amount of quantification through timing and manual guards?

Let IKA give you a whole new choice. The RV 10 Automated Rotary Evaporator integrates patented quantitative distillation technology to make quantification accurate and simple!

How simple? !

You only need to set the initial volume and the distillation volume in the RV 10 automatic control type to achieve instrument quantification! As shown in the picture below:
