SEOHPipet Pipette Filler Bulb with Elastic Band Silicone Liner Seal

Works well as it should, no problems.

We use these to prepare standards in our lab. I found this set at a great price!

I have yet to use the pipette filler bulb but the price and shipping are amazingly much lower compared to other sellers and I didn't have to buy them 3 at a time. I won't hesitate to do business with them again. I'll like have to order other things since my lab kit is still incomplete. Thank you.

They're standard sized pipette bulbs and they fit my glass pipettes. They work as well as any other pipette bulb I've used.

Great.
