Oxalic acid (OA) vaporizer

The price differs greatly with the MK 350 now on sale for only $195 right now and the provap at a jaw dropping $485. The specs look pretty much the same equipment and time requirement wise. I’m also in Canada so our dollar is terrible right now so they are more like $266 and $662 Canadian

I just bought one of these. Looks like a great product at a fraction of the price.
I have not received it yet. But Looks like it will work great.
And Canadian built.

Thanks for the heads up guys. I just purchased one from Joerg and so far I was impressed by the customer service. I’ll let you know when I receive it and let you know my thoughts.

I asked what size of truck inverter he recommended and his response was a 1000w inverter. I will probably use a generator this year but will look into an inverter in the future. Thoughts?

The MK 350 has a serious design flaw in its stem. The first problem is that the soldier used to hold it has a melting point lower than the working temperature, it melts and the stem falls out.

The second problem (also with the stem) is that the bend is away from the heat and plugs easily. Unplugging it is not so easy. Looking at the competitors you can see that they figured this out and put any bends under the heater to keep them hot and clear.

I have pointed this out to them and hope they fix it as the rest of the MK 350 seems fine. Time will tell on that front.

How's the plugged stem rate on that one compared to your other one? The bends in the MK 350 get clogged every other hive.

No problems with mine unless you push the end into some propolis. It also gets up to operating temperature in 2 minutes, I guess I could claim to have the most efficient band heater vaporizer out there. Dont even have to do a special offer to beat the price either.

So I did go ahead and purchase the MK 350 with great customer service however I have yet to use it. I will give my thoughts on it in a bit of a review on this thread come November’ish when I plan on using it. I will be using it on 40 colonies so I should see any and all problems this year but hopefully it is smooth sailing.

Quality does count for something. Tomorrow will be inoculation #2 of a 3X5 series for 2020 for the start of the fourth trouble free year for my PrpVap110. Yes, I do clean it up after use. It has been a blessing.

Well I guess the Easy Vap and Easy Vap Pro are not good at knocking in fence posts, But the first one I made in 2017 is still going strong.

I just came across another vaporizer and wondered if anyone had experience with it

Effectively Treat For Varroa Mites | Honey Bee Care
The MK 350 terminator

At about half the price of what I would call the standard provap 110

ProVap 110 Sideliner/Commercial Vaporizer :: OxaVap – Your Source for Oxalic Acid Vaporizers

I guess I’m in the market and wondering if anyone has experience with either of these or advice. Also if there are other competitors?

I have a nice little machine shop so I just made a new Stainless Steel cook pot with a heat sink and aluminum caps for my MK 350. It's much better than to one it came with but I need to build one with most the stem under the heater. I'll need a different heater for that so this will need to get me by.

I did figure figure out a quick fix for clogged stems. Keep a mini torch nearby and heat the stem until the clog turns to vapor. It's fast and doesn't cool your pot. View attachment 57813 View attachment 57815
