The joy of giant pipettes

[Jameshowison]

If, like me, you enjoy using a speed stir, you might also enjoy using a giant pipette to get your 10ml samples. Beats bending over to stare at your test tube, then trying to remember whether meniscus goes up, down, or even happens on plastic. Plastic from which the scale is coming off anyway. No trying to decide if the unexpected results are inconsistency in your sample collection.

I've been using this one for the last year. It was ~$45 through Amazon (and that's still the price). Very simple to use (stick in pool, plunge, pull out, stick in tube, plunge again. Done).

You can also adjust this to get 5ml samples (if you are doing a high FC SLAM), I've also used it for 25ml (2x10ml, 1x5ml).

No affiliation, just sharing to have something to contribute for all I've learned here at TFP.

James,

I like the Taylor Sample-Sizer, but you do need to use Taylor cylinders..

SampleSizer, 10 & 25 mL, anodized aluminum (for 9056, 9057, 9058, 9198)

Thanks,

Jim R.

Yup, that is one pretty chunk of aluminum

Maybe tftestkits should sell the pipettes as an accessory.

I use a wash bottle to fill from pool and add to beaker - allows to squeeze at eye level with good accuracy

Might be a silly question, but how does this work? I don’t see a desc on the website. I have come to enjoy testing, but eyeball leveling is my least favorite part.
Thanks!

but how does this work?

Keri,

The sample-sizer is just a chunk of aluminum. You add sample water to the cylinder and then stick the sample-sizer in the cylinder and it displaces the sample water. If you put in the fat end you will be left of 10 ml sample, and if you put in the thin end, it will leave you with a 25 ml sample.

Simple, but works great for me.

Thanks,

Jim R.

Simple is the way to go. I think I’ll order one. Thanks!
