Purchased for experimental work. I think that ease of use does not differ greatly from other products.
Speaking of what you are worried about when using pipettes, pipettes 1 - 10 mL will easily turn around when installing and removing chips, the amount collected will change there.
So it may be better to use once after confirming the collection amount and setting the reference position.
In addition, another person made a review related to the O ring, but with the answer attached, the type of the compatible O ring which is important is not written.
As we confirmed it, S - 11.2 was a substitute item.
Since the contact part with the chip is only the rubber band, the contact area with the chip is narrow, and when liquid is sucked and transferred to another place, the liquid drips down. Naturally, in that case, it was disqualified as a pipette for dispensing quantitative amounts. Even though I think that you are inserting tips firmly, it will be frustrating when liquid drips.
A certain amount of liquid dispensing in teaching material preparation.

Since we can quickly dispose a certain amount of liquid, I felt that it would shorten the preparation time of the teaching material and lead to a reduction in burden. I am involved in the junior high school science department, but even with multiple dispensing, there are not many extreme differences and it can cope well with the request content in the textbook experimental items. I think that it can be more reliable if there is a guarantee that we can cope with highly viscous liquid reagents and corrosive chemicals.
Use in practical training at high school (educational purpose)

I had almost no sense of incongruity with the same feeling of use as Pipettoma ○ I used in my school days. Ejector of chip is also attached. Since the body is transparent, I think it is easy to deal with contamination. Considering from the price, I think that it is quite profitable. I think that there was no more choice if it is personal use or practice at a high school.
