RSST New Tank Material Discussion

[HandbananA]

It appears the new RSST's have a different tank material so please discuss any info or issues you have here. The new ones have a milky white color vs the frosted glass look of the original tank. Also the new tank is smooth on the outside and textured on the inside while the original has texture on both sides(AFAIK).

Is it still Polypropylene?
If not, what is it?
Will it crack or melt with known tank killer juices?
Do you like the new tank?

I'm no plastics expert, but I believe the originals are polycarbonate. The newer ones are polypropylene. Polypropylene is supposedly more resistant to some chemicals. This is probably why the material was changed.

lol I guess I suck at making threads.

anyways I noticed the center tube is chrome plated brass, what a dissapointment

I don't really use tank cracking juices so I probably cant comment on how the material is holding up.. but I will say this - I have both of those in the picture and the first one seems much better built than the new one - I had threading problems and leaks with the newer one - the 1st one seems much more trouble free....

The threading problem seems to be happening with some of the newest ones. Some of the vendors are exchanging them. The leaking appears to happen with any of them. It's due to a poorly sized top center post seal.

Maybe on the newer version, but not on the first-run with the milky tank. Watch Todd's review -- he takes a tool and deeply scrapes the center tube because he thought it was chrome-plated as well, and discovered it's not.

Even if it were, I've never understood the concern over chrome plated brass. Chances are, your kitchen sink faucet is chrome plated brass. The temperatures inside an RBA will never approach the point where any breakdown of the metal might occur.

Not all chrome plating is equal

If you ever say the photos of the original Dream atty you would know what I mean as the chrome plating was lifting after a couple of tankfuls of juice had gone through them!

But

Like you, I don't have any real issue with it but I do keep a close eye on it to make sure it isn't lifting

Possibly, but the brass underneath is a definite concern. Most brass contains lead. I don't need that in contact with my juice. Not so much an issue on the RSST with the way the tank is designed, but they use this stuff in everything from ViviNovas to IGO-Ls.

From wikipedia:

"To enhance the machinability of brass, lead is often added in concentrations of around 2%. Since lead has a lower melting point than the other constituents of the brass, it tends to migrate towards the grain boundaries in the form of globules as it cools from casting. The pattern the globules form on the surface of the brass increases the available lead surface area which in turn affects the degree of leaching. In addition, cutting operations can smear the lead globules over the surface. These effects can lead to significant lead leaching from brasses of comparatively low lead content."

The milky white tank from recent rsst batches looks like it's made of polyethylene or LDPE. I know some juice bottles are made of this plastic but unsure how this compares to polycarbonate

probably HDPE, High Density Polyethylene, LDPE would be too soft, the milky white juice bottles are LDPE, the crystal clear ones are PET (Polyethylene terephthalate) which would also be great for tanks. Unlike Polycarb, PE is not effected most solvents.

Has anyone looked into a glass tank for the RSST?

Also, lead-free brass exists. I expect or should I say hope china is using this in their atomizers.

yeah I got one of the newer ones, I scraped it and the plating came off. I was just expecting it to be all ss.

I would think that any juice in contact with the center pin would never make contact with the wick, as it would eventually pool in the bottom of the device outside of the tank. I personally dont reclaim this liquid- just wash it up and down the drain it goes

 

[fooey]

Are you referring to the 510 center pin / pole? I'm having more voltage drop with my new rsst compared to a aga-t so if its chrome plated brass im going to sand the chrome off.

↑Yep. The center tube, whether it's stainless or chrome plated brass, won't come in contact with the coil, because of the tank design in the RSST. The center tube is shielded by the inner plastic tube, which is part of the tank.

This new tank, regardless of materials, looks nicer than the stock one at least... Do you guys know where to get one?

I was more concerned about it for the possibility of modding the RSST for a pyrex tank. It's already been done in the ceramic wick thread.

But agreed, it's not really an issue with the stock tank.

I have an early RSST and the center tube was chrome plated brass. I know this because it fell onto the floor and stipped the softer brass threads. Even if it doesn't come into contact with the juice, it's a bit annoying as it's advertised as all SS atty. I ordered a new one but have a feeling it will fail the same way if I drop it as the threads are way too fine to be brass and structural.
