I'm curious if this device has a stoppering function. I just sent them an email asking about it. I'll let you know.

From what I understand, I should have options rated down to -80 degrees Celsius. These only go down to -50. I also have a showroom in my country for a Chinese manufacturer. I'll definitely go there to talk to them and see the equipment before buying.

Just pointing out stoppering available in the same model.
I got in touch with HarvestRight’s support team, and unfortunately, none of their machines come with a stoppering function for sealing vials.
I also spoke with a lab technician who has some experience with lyophilization, and he shared a few important insights:
He also mentioned that the whole lyophilization process is often overcomplicated or “demonized,” but in practice, it’s relatively straightforward once you know the basics.
I also spoke with a lab technician who has some experience with lyophilization, and he shared a few important insights:
- Laboratory freeze dryers with a protruding dome should generally be avoided, as they have poor temperature stability, which can cause degradation of the samples and vials being lyophilized.
- It’s best to go for front-loading machines with proper doors and shelves.
- Ideally, the system should be rated down to -80°C. Of course, no machine will actually maintain that exact temperature under load, but the point is that if you’re running a large batch—say 200–300 vials—a unit designed for -50°C won’t hold that temperature under the stress of the higher volume. That’s why a -80°C spec is essentially a necessity.

You forgot C: basement dwelling over-posters who have to comment on every single thread as if they have expertise but they’re really just making shit up.

And passive aggressive pussies who start shit, unprovoked, once in a while to feel like they don't pee sitting down.

Your AI instruction list forgot step 1, which is test your raws.... so I wouldn't put much trust in the rest of it

With no consideration given to the expense of a proper facility to set the 90k worth of equipment into.
It’s called trial and error - not the same thing as mixing some powder into a cup of oil. If you wanna make a nice cake you better get off your keyboard and go get your hands dirty.
