quantifying 1 gram of Oxalic acid crystals

[drex]

You would not expect a pharmacist to guesstimate the amount of active ingredient in any medicine prescribed, so why do it for medicine for your bees. As said , scales are cheap on eBay

1g.

I hope you are not making space cakes there Mr Redwood.., i found around half of a normal tea spoon heaped weighed 2gm, i have little tubs to put it in i know roughly how much is in there without weighing every time, the main thing to consider with the tea spoon do not compress it, it needs to be loose and fluffy so to speak.

Not far wrong there, I use a half teaspoon measuring spoon I had in a Christmas cracker that is exactly 2g heaped but not overflowing. I use to weigh them in the house and wrap them up but can be a bit fiddly at times JBM has the best idea, he bought lots of little plastic containers, he fills them in the house and when needed he flip the top and empty contents into the vaporiser

Just bought a set of ~Salter Scales from Sainsburys on Saturday past for £14-95 I think they were and accurate to 0.1G.

I wonder how true that claim is and if the calibration is adjustable?

 

[For want of a better word]

Callibration is easy
A 20 p coin weighs 5g
so weigh a selection of 20 p coins and take the average on your scales

If average is 5g your scales are accurate
if not....
ie if all your 20p coins weigh 5. 178g... weigh out 5.178 on your scales abd you will have 5g.

That would be 1.0356 scale reading for 1g or 2.0712g for 2g

Bet that the Apipoxall £11 for 35 pennyworth sachets are not that accurate!

Yeghes da

Calibration needs to be done at e higher end of the scales also.

Perhaps I could weigh 1 g here and send it via mail to you. Or I send £ 10 to you and you buy own digital balance from Lidl.

What a really generous and kind off.

Can anyone roughly quantify 1 gram of oxalic acid crystals?
would they represent the size of a pea or marble for instance? 1/4 teaspoon? 1/2 teaspoon etc?

I don't have any scales that are that accurate.

Purchase OA in 1 gram tablets . Packed in boxes of 100 tablets !

Buy some calibration weights...they cost less than 2 jars of your sold honey.

By a syringe from chemist and cut of the spout set plunger to 5ml for 3g
More than accurate enough and an easy way to dispense into hot pans.

It is rather OTT to talk about measurement exactitude to 0.1g when using a delivery method which relies on sublimated vapour flowing round a hive, landing on surfaces and varroa landing on it. There are BOUND to be areas in the hive which get more than others - and some which get a lot less.

All you want to ensure is that the dosage is not so low that it does not cover most of the surfaces. As overdosage by 100% (LASI) does no apparent harm, far better to slightly overdose as a matter of course..

 

[Eyeman]

These have worked very well and give consistent readings when tested against coinage and notes.
Not bad for under a £5

I think it's crazy to measure the dose to fractions of a gram. I fill the Varrox pan level for a single brood box, slightly heaped for B+1/2, heaped for double BB.
IMHO the advised doses are totally arbitrary.

The problems arise when a newbie doses with a tablespoon

These are cheap enough Look at this on eBay http://www.ebay.co.uk/itm/301207154139

Got one - why bover - bl**dy nuisance carting that to my three apiary sites.?

Make your life in the field simple.

Take one small plastic measuring spoon and weigh the contents when filled level with OA to the top - not heaped . It should weigh in the region of 2.5g +/- 0.3g

So now when you are a wet, windy dirty cold apiary surrounded by bees and with propolis and honey stained fingers/gloves, you don't need to mess about with weighing - but just fill the spoon level - or heaped - or half full depending on what you need.

For a hobby beekeeper that is all you need.. a fast simple easy to use method that is very easy to modify to give more or less than a standard 2.5g dose.

That is how I do it - and it ensures I make no mistakes in weighing/stand on the scales/etc etc..

If I can do it, anyone can

You can calibrate with coins.
