Grain jar lids... Simple question
#23488854 - 07/29/16 10:20 AM (7 years, 7 months ago) |

I bought these lids to use on my grain jars..
The vendor said that they are supposed to be used for that, but come to find out with extra reading, that the syringe filter isn't optimal for GE with a grain jar..
So heres my question. Ive obtainted some tyvek envelopes, and was wondering if instead of using the entire circle size of the lid, could i just use a square cutout like the photo below? Or am i missing some crucial point of info for the circle size? Yes i have the blue injector ports.

I can't say for sure, but I think I remember folks recommending against postal tyvek?
To answer the question, no you don't need filter covering the whole lid. Yes you can just cut out a hole and RTV some filter material over it. Size isn't too critical, about the size of a dime I would say. Though I have some that are borderline pinhole size and some that have two filter holes the size of nickels that work okay, you can't fuck the hole size up too badly is what I'm saying.
Here's a good cheap tek that uses EZ-felt, cheap/superior to tyvek.

In that picture that is a circle of a synthetic filter disk over the hole, and would be a better choice for you than Tyvek. SFDs last a long time, most people replace Tyvek after one or two runs. Other options would be ez felt or polyfill.
You can buy SFD's and trace a coin, cut them out and silicone them over the hole after ruffing up around the hole with sand paper so the silicone holds better. You can get enough for about 8 lids out of one SFD.

I would use a SFD. You can buy them in small sizes or get full sized filters and cut them down yourself. Use high temp silicone (red) to attach the filters.

I'm gonna be honest here, you could use a plain unmodified plastic lid if you wanted. It's just less forgiving.

But to that end, Whatman are better suited to LC tho I have used em for grains. However I would say if you were looking to make permanent lids to avoid tyvek, which is a bit sketch. Like many things it can be made to work but is unforgiving.

I drill a 3/8" hole through a plastic storage lid. Could also use two piece metal lids, but I like the simplicity of the one piece lid.
cut up some EZ Felt or SFD material
'glue' it on like the above posters explained. (kinda a mess, but you can handle it).
good luck

Thank you guys all so much for your replies.
I am planning on using SFD its just i have to order them online bc all i can find in stores are coffee ones. Does anyone know a store that carrys em?
Im looking for something to use tonight, or a way to use what i have. I dont plan on sticking with tyvek, i just want my first two grain jars to get started. I didnt stagger my projects like i shouldve. So im looking to use tyvek for tonight, then within a week, getting the SFD shipped here and having a more permanent solution.. Ya know what im sayinn?

3/8" hole stuffed tightly with polyfill. Been doing it that way for months, No problems whatsoever, super easy, no stress, no mess.

did you read the full thread, especially this post which most SHIP detractors either ignore or possibly never thought of, because I cannot remember a decent response to say it does not work.

Ports are definitely not useless. When working with LI or LC it's nice to not have to mess with a SAB. Just clean the port, flame the needle and bam!

Ports are garbage. I still use them out of laziness but still do all injections in a SAB you're stupid not to for how simple and easy it is to set up a sab. It's an upside down box...

Good thing I didn't call anyone stupid. But I did imply it takes stupidity to think a SAB is a hassle. It's like not putting your shoes on before leaving. That's how stupid it sounds to waist the time on 90+ minutes of sterilization and the electricity or gas, and then the raw materials. Just to not have to flip a plastic box over

I guess if the method didn't work you might be right about it being a waste. I'll use my SAB for the work I deem it necessary.

SAB would have been the difference between 89% success and 100%. Or 8oz vs 9

If you plan to do g2g you dont really need injection port, just stuff poly in ~1cm hole and you have it. If you plan on using any type of lc or spores make ~3mm hole and cover it with rtv. Theres no need for complex lid systems. If your sterile tehnique is good you can unscrew lids and squirt under without the need for rtv ports. Try to better your sterile tehnique, not your lids.. Its harder, but it pays out in the end.
