Selected User Reviews For Heathrow Scientific HS20623 Safety Bulb Pipet Filler (Pack of 3)
A safety bulb that is real and original is a great safety bulb. There is a distinct difference in the insert, which is hard and not soft like the originals, and the pipettes get stuck in there. My sample bottles have been spilled lots of times as a result of this. You have to be very careful when using them because if you put too much downward pressure then the needles stick, and if you put too little pressure, the needles do not.
It is very easy to remove the liquids with these little pipet bulbs. When I first saw their size, I was sceptical, but they do an excellent job.
It is convenient to be able to measure exactly how much they weigh because they fit in the palm.
There are better pipet fillers available on Amazon if you need one for certain applications.
Pipettes with a capacity of 10 ml are compatible with it.
I am very happy with this.
You can see them in the picture. They are a really good company for my tech.
