Review: Works great! - Works as described.
Review: Not the prettiest, but it works - I use this with a 10mL pipette. I originally got it for use with yeast culturing for my homebrewing where I need to measure out 10ml of wort into test tubes and also found that it is a handy way to get pool water from well below the surface when I measure chlorine without getting my arm wet up to the elbow. This bulb seems to work OK. The BB's inside tend to move around a lot and make their way out of the valve and out or into the bulb, so you need to be careful how you squeeze the valves. Once I figured that out, it seems to work OK. I am not sure how long this part will last. When I received it the rubber seemed slightly cracked on the surface and discolored. Maybe it had some sort of varnish on it. Anyway, it hasn't had any problem with cracking or leaking.

## Questions & Answers

**Q: about how many ml does this bulb suction up/ dispense?**
A: This tool is versatile as it can pipette any volume from 5ml to using superior valves (air expulsion and download). The fully compressed bulb syringe can suck about 150ml, if you want more volume, press the vertical valve and suction air expulsion more liquid again. Remember this all depends on the volumetric capacity of the pipette used. Less than 5ml pipettes are difficult to handle with this accessory seguiridad laboratory. I hope you find it useful.

First try it slowly drained with no control. For years I used these with no problems. Would not buy again.
