Need help measuring

I am looking for something but I don't know what it is called.
I am having lots of trouble trying to measure liquids with a needle and I was thinking that it might be easier to use something else.
I saw a hand held machine that looked like they just used one hand to suck up the liquid and then pressed a button to empty the liquid into a bottle. it looked really simple and easy to use.
I'm not sure if this makes sense and gives you any idea of what I'm trying to explain, but I'm open to all suggestions and help, and if you have an idea of what I'm writing about could you please include a web address.

Thank you for your help and Merry Christmas

 

Pipettes?

Pipette - Wikipedia, the free encyclopedia

Thanks for that Kev.
I think a pipette pump would suit my needs, just not sure how easy they are to use or even how use them.

 

Hi Ken .... I think a pipette pump or bulb with pipettes would be the best thing ever for you ... Wiltronics in Ballarat have a huge range of stuff at good prices and reliable delivery
the rubber bulbs fit on the end of the pipettes and suck liquid up into them ( you squeeze the air out ... insert pipette into liquid and when you let go of the ball it sucks the liquid up into the tube ... then to release you just squeeze the little valve bit on the side , and it lets air in slowly to allow the liquid to dribble out
there are also pumps that do the same and these are very accurate ( but cost a little more )

Glass pipettes

Polystyrene pipettes ( not as breakable , very cheap , but not as easy/quick to clean )
Wiltronics - Pipettes Serological Polystyrene Sterile

Bulb and pump fillers

Oh and I have had YEARS of playing with these and can walk you and Joanne thru using them

 

Thank you Fatman.
I have been looking at the handheld pipette pumps, but there are so many and very different prices, I'm getting a headache.
I might wait a day or two and have another look with a fresh head, if that makes sense.

 

No worries Bull ... I think a rubber bulb and poly pipette combo would be a good start for you ... get Jo to have a look with you )

You could also go the way I do and use poly measuring cylinders

( I got a cheap set of 5 off ebay )

They look very useful and I could pour the finished liquid into the bottles.
Are the easy to read?
I think plastic would be better for me incase something happened and I had an incident.

 

Yep very easy to read ... not as accurate as a pipette set up ... but if you are dealing in millilitre measurements rather than fractions of a millilitre they are good enough
The only drawback I found with them is the smallest measurement you can accurately make is 2 ml by itself be.comse the 10 ml cylinder ( the smallest) starts its scale at just under 2 ml , but for being accurate UNDER that I would use a syringe anyway ... but for measuring the larger components they are dead easy and fairly accurate

If you want precision tho ... pipettes are the way to go !

I would recommend the WILTRONICS ONES far above the ebay ones tho !!!

 

And to add to FM's comment ... the Wiltronic ones are very good, cheap and fast postage ... and absolutely fantastic if you make a large batch (I'm making 100ml batches as we speak ... be back in 1 minute )

 

Okay ... 3 minutes

If you go measuring cylinders and are worried about glass .. these are the ones to go for Bullos ( but the glass ones usually bounce lol )

 

Some of the measurements are less than a millileter, like 0.27ml for example.
I like the idea of the handheld pump, but not sure how easy it is to use and if you need to get the pipette bits and cut the build end off them or if they come with a nozzle with the mls on them.

 

Ok to clarify ... a pipette is just a long tube with very accurate markings on it so say in your case with the 0.27ml you would use a 1 ml pipette , suck juice up into it up to say 0.5 ml , then using the bleed valve ( the bit that lets air in slowly ) you let it drain down until you see it at 0.27ml .... then you take that liquid thats left in there ( the0.27ml ) and put the end of the pipette into your mixing bottle and drain it into it ... which gives you the exact amount you were after straight into the mixing bottle

Pipettes areTHE best way to accurately measure liquids , and with the use of the pumps can be very easy to use
a good video here

The video does show how to properly use the pipette, for 0.27ml you would draw 1ml of fluid, then let it drain down to the 0.73ml level. The tip is the no go zone, you will not know how much liquid you have in the pipette if including the tip.

 

I stand corrected ... I repeated the proceedure for a residual pipette instead of graduated ( residual takes into account the bit left in the tip lol )
... brain fart .. apologies !

As Filbert said . you do a subtractive bleed off

 

Does anybody know if a pipetor would be able to suck up VG?
Joanne can't look becuase she is very sick and she is making me confussed be.comse she has been spending the day in bed and when she gets out of bed she has been carrying a roll of toilet paper around with her so I'm not really sure if it her nose that is sick or her bottom.
She is coughing a lot though.
I am making her roasted lamb shanks, with roast pumkin, steamed broccoli, .comliflour and peas, and also some meat .comce from the trivet, which is whole roasted garlic, and finely diced carrot and onion and a little rosemary. Hopefully that will make her feel a little better.
Thank you for all your help Everyone.

 

Crikey ... I might get sick , just so you can cook for me !!!
VG will go into a pipette but it will be harder to suck up .... my advice would be to mix VG and PG together first in the right mix you want to thin it .
I would use cylinders to mix the bigger quantities ( over like 5 ml ) and leave the pipetting to the small amounts
Hope Joanne feels better soon ... give her a kiss on the cheek from me !
( not the bottom cheek , just in case it IS her bum she is sick out of LOL )

 

There are a few types of pipettes. We'd belooking at graduated ones here. You can get them with zero at the top or bottom, complete delivery type etc. but the problem here guys is the mixture is so thick that something like half of the measurement will be stuck to the sides. They are calibrated for water.
Same (stuck to the sides but to a less extent) goes for measuring cylinders. TC and TD types (to contain and to deliver) but again calibrated for water. eg, with a TD cylinder when measuring water, pouring out in one motion and held almost upside down for several seconds will deliver the correct amount. About half a mL of water will be left in it but its calibrated for that. With VG, there would be something like 20mls left in it unless you let it sit upside down overnight.
Could use the TC method and mix it all up to say 100mls then shake, then the mix will be ok. Problem this way is you only get one chance when filling each ingredient not to stuff it up.

Few types of pipettors (which I think is the pump you are talking about), the only type that would work properly is a positive displacement pipettor for thick liquids. It has a piston and acts like a syringe, one handed action, accurate and quick. But expensive and over the top as we get the same result using a 50cent disposable syringe.

It's a bit of a PIA sucking up VG through a needle. I have these special piston displacement jars that makes syringing quick, easy, fast and one handed with a syringing nipple . No air ever gets in the jar, you dont even ever have to lift the jar off the bench. I even have the different jars with different liquids stored away with the syringe still attached to each one and it is still airtight (in theory).

They are made out of PP and meant to be disposable (I keep reusing them) but I should post about it one day as it might be a good project for someone to make them out of SS and orings or something as a permanent storage / dispensing vessel.

 

Oh, forgot to mention, no needle is used with the jars, the the bare syringe tips fit directly in.
and Beakers are not meant to be accurate. 100mL could be anywhere from 75 to 125mL
