Does anyone know what I can keep in with my raws to keep them fresh? I was thinking silica packets like you get in prescriptions, but maybe that’s wrong. Someone mentioned it in this thread a while back, but I can’t seem to find it. Any help would be appreciated.

Silica packs in sealed glass jars would be correct. Disregard the plastic bag in freezer advice and other garbage recommendations.

Not sure buddy I stopped at 200. I think the enanthate esters are pretty forgiving. I'd GUESS that with 2/20 it might hold up to 300 but that's a guess

I wondered about this too but I literally have not seen one person go beyond 200mg/ml of mast E with a 5-10% overage. I know it's enanthate but so is primo and mast may have a high molecular weight. Never checked.

This kept me at 200 which is easy with 18 or 20%bb. Would have loved to go 300mg though.

It's worth a shot. Now that you mention it, I did od mine at 10% so 220 isn't a problem.

If you want to know how high you can go with something, try it. Kind of like learning to ride a bike, not that hard.

Pinned a 1.1ml of it this am
Pushed fine through a 29ga slin pin
Zero pip .

Anyone willing to share a few options on scales? I know I need something that measures .001 grams, but I’m not sure what the average cost is, etc. If someone could share what exact kind they use that would be awesome. Thanks.

My Gemini-20 has been great, inexpensive too. Then again it maxes out at 20g. Not sure in what scale you are going to be brewing, definitely recommend it though.

Small scale. Going to grab one of these. Thanks

I did 250 with no overdose. Held fine with 20% and mig 840. I'm sure I could have gone higher.

Favorite brand of BA/BB when ordering from the 2day shipping site or does it really not matter?

Also, found some interesting info while researching in the lab about using a certain type of filter I can't remember if it was PVDF or PTFE but ones of them doesn't actually have the all clear to filter both BA and BB from a lot of filter manufactures and both filters membrane seem to show up a lot around here, along with Nylon. Also RC is a recommends media from a bunches of companies for both BA and BB but I nevers hear it mentioned, do they not make them our size or some other reason no one uses them?

I thought that the main filter media restriction was more around PTFE not being able to be used for the stronger solvents (EO and Guac)? But PVDF being gtg for just about any of our brews?

 

[JackSmooth]

That dry clave I snagged up is awesome. I see them on eBay all the time for about 250-350. You can only fit a 250 media bottle at a time with the 25 vials. But it works great. If you're not brewing liters at a time it's perfect.

Nice new avi bro. Your ink is fucking sick!

@XmadXscientist
How about using a Vaccum sealer? Would that be suffice? And perhaps throw a couple packets for Ultra Safe Measure?

If they’re Mylar bags maybe but put them in mason jars too as almost every type of bag readily available via retail still transfer moisture and that what will cause raws to degrade faster.

Need to orders more membrane filters for both oil and bac waters use. It's either Nylon or PTFE I know both can be used but is there really a preference? I can't find 47mm PVDF or that's would be in the question as well.

Recently used pvdf membrane for bac water, worked perfect. I’ve used both nylon and ptfe for my oils, mostly nylon.

Pvdf would deff be the better kind to use so u don't have to worry about certain chemicals eating through it

What type of bag do u recommend besides vacum sealed I keep my bags submerged in rice inside of a big coffee can like container but its plastic not metal do u think that will suffice about a year is the longest they will sit

Can’t finds 47mm PVDF membranes, if anyone knows of a place to by it I’ll look ins to it. Think I’ll go with nylon, I don’t think it’s hydrophopics so I can use it on bac water easily. I know they make hydrophilic PTFE but not sure how easy they are to get, a search pulled up one source, min order 400.....

olytetrafluoroethylene
(PTFE)/Teflon®:
Hydrophobic membrane. Resistant to
organic solvents as well as strong acids
and bases. Low protein binding. Low in
extractables. Main applications are the
filtration of non-aqueous samples. Prior
to filtering of aqueous samples the
membrane must be pre-wetted with
a water-miscible organic solvent.

Polyvinylidene Difluoride (PVDF):
Hydrophilic membrane. Resistant to a
broad range of organic solvents. Low
protein binding.

Polypropylene (PP):
Hydrophobic membrane. Resistant to a
wide range of organic solvents.
Polyethersulfone (PES):
Hydrophilic membrane. Broad solvent
compatibility. Suitable for filtration of
aqueous and compatible organic sol-
vents. Higher liquid flow than either
PTFE or PVDF. Low in extractables.
Low protein binding.

Nylon/Polyamide (NYL):
Hydrophilic membrane. Resistant to a
range of organic solvents. Suitable for
use with high pH samples. Binds pro-
teins hence not suitable for protein
recovery applications.

Cellulose Acetate (CA):
Hydrophilic membrane. Limited solvent
resistance. Very low protein binding
capacity and hence excellent for protein
recovery applications.

Cellulose Nitrate (CN):
Hydrophilic membrane. Limited resist-
ance to organic solvents. High liquid
flow rate. High protein binding capacity
and hence not suitable for protein
recovery applications.

Regenerated Cellulose (RC):
Hydrophilic membrane. Resistant to a
very wide range of solvents. Suitable for
use with either aqueous solutions or
organic solvents. Compatible with
HPLC solvents. Very low protein binding
capacity and hence excellent for protein
recovery applications.

Hey I just googled 47 mm pvdf filters an some came up on Amazon an eBay like 30 bucks worth hope it helps
