Default Liquid flux dispenser bottles

Last week I had a couple of contre-temps involving flux, one of which resulted in a messy puddle on the component side of a favourite piece of kit. A lot of meths and T-roll later I stopped to look at the dispenser bottle and saw it was splitting at the top. I have long since bought little polythene bottles to dispense common domestic and workshop liquids, including white spirit, penetrating oil, IPA and flux, and had already found they softened with xylene which then evaporates. I went looking what the professionals use and found a range of bottles, like this Multicomp ESD Flux Dispenser Bottle with Pen Tip, 57ml which additionally protects your flux against electrostatic discharge. With the price at £7.26 I decided only my flux needed such protection, but it looks like the right item, quote
"By its chemical nature, it will not have any chemical reactivity with solvents (such) as TCE or alcohol. The pH of the de-ionized water solution tested were the same before and after a seven day period. No colour or physical change was noted for any solvent tested"

While I was waiting for my order to arrive, I crossed a car park closely observing the ground in the hope of finding the last of the disposable vapes which have now been banned. No vapes, but I did find my first example of what it seems we will now be finding: discarded vape fluid bottles. This was of high quality, clearly meant to be resistant to TCE and alcohol.

These hold about 20ml, have only just enough flexibility to dispense one small drop at a time, and with the label peeled of look the part; 20ml seems a safe amount to have on the bench. Be on the lookout around park benches and bus stops!

Default Re: Liquid flux dispenser bottles

Useful tip!

The slightly bigger bottles ladies hair dye is supplied in are also great for things like PVA glue, water to wet your soldering iron sponge, and so on.
