As a professional chemist with more than 25 years of laboratory experience, it is easy to spot a product issue. While this bulb model is made with good design that works, the bulb we received is sticky to the touch. It is not normal for rubber products to be sticky, and in fact, stickiness could possibly mean that the rubber is so old that it is decomposing, or that the rubber polymer itself is defective in some way. If your finger sticks to it as if there was glue on the surface, then something is wrong. We are returning ours for a full refund.

I added this to a 50ml pipette and it works great. You can decant in two different ways.

Although more expensive then other ones Amazon sells, it is worth it. The Air, Suction, Exhaust button all work very well on mine. Rubber is soft not hard, and expecting it to last like it should. If you have ever worked in a lab it is like that quality, but you will have to pay for it.
