You should invite him to the forum…Imagine if we had a Chinese glass maker here too…This place would be bumping with customs stuff.
Thanks for the review on the seller and letting us know.

I currently can go from 250ml to 2000ml . I originally bought a 2000ml setup not realizing how much product was required to run it. So I started going smaller to be able to run.

I just did my 1st QWISO and I also realized how much crude it would take to run a 2l system. So my thoughts were to down size the system plus run a single cow. With this type of system should allow me to reach a lower vacuum with less possibility of vacuum leaks

Keep the cow just after a run keep heads in a jar and tails once jar reaches 250 ml You run em in a 500. Ml flask in the 2 liter mantel Some aluminium foil And iT works
This way your mains are perfect but You dont loose material

What are the main issues we see with Chinese made glass distillation setups? Shitty glass joints that don’t seal good? Implosions? How many ppl have had Chinese SPD units or other Chinese pieces in their setup break, crack or implode on them?

So I’m finally putting in orders for my SPD setup 
. Anyone use one of these for their head or side neck thermometer adapter? I like the idea of an o-ring there to seal it up for simplicity sake, but I think I have heard complaints of o-ring seals for SPD if memory serves me right.

Joints seizing and leaking are a big problem I’ve had happen several times using cheap gear very When using better quality like Rocco glass I’ve never had an issue. The other major issue that not many people talk about is inconsistencies in the glass (wall thickness, shape etc) and on the surface of the glass which cause friction, issues with heating, and air flow. These things eat your efficiency alive and produce inferior products. If the difference in price is, let’s say 3k between a cheap kit and nice quality kit I struggle with how it makes sense to not spend the money. All it takes is one leaky seal to ruin a batch. That batch costs way more then the difference in price.

@Poizzin How do you like the quality of your HK single cow. I am thinking about having that ebay seller make me a 5l xl head with 2 vigreux so i can pack it with 24/40 joints all around. That way I know I will not have any issues with setting up a small spd.
I’ve had good luck with the Chinese glass, they leak some but can be fixed with a little patience and good vacuum grease. I would love to try good glass but can’t afford it until I open my business. Right now I am in learning mode.

This take off is incredible. The flow is incredible compared to standard cow. I am still using a gl14 connecting to the cold trap. So my next purchase is the correct cold trap and kf25 adapter . Then the new delta 9 5l head

That’s great news. I have some so called American glass that not as thick as my Chinese stuff. So I am reluctant to change glass suppliers.
Honestly American glass can be good or bad just as Chinese glass can be bad or good. It all depends on where you get it, the quality of the materials used and the end price point.

No matter where you are you only get what you pay for. Here’s my system as of today.I will be doing very small custom runs so I don’t think I go over 1000ml. Boiling flask with be single neck as I will rely on temperature probes on the bottom of the boiling flask for my temp. reading’s 5l xl head and the single cow hooked up to a custom 24/40 female 1000ml cold trap with a 24/40-kf25 adapter directly to a ss bellows. I plan on running a hard line system to minimize leaks. What type of grease you use?
Currently dowcorning high vacuum grease

So is the idea on that adapter to use the isolation stopcock and swap receivers?

When turning a multi-distributer cow, is it as easy as just turning it on the head joint while running or do you need to depressurize for that as well?
