Yeast Containers (same As Whitelabs Tubes)

[goatherder]

PET will start to melt around 75 degrees. If you are needing to autoclave then polypropylene would be a better choice.

Franko I think the Coopers PET caps fit these

[Franko]

yes they will

What a bummer, I gave 100 empty White Labs vials to Crozdog. I knew I should have held onto them.

I will second that. You will need to sterilise them when you get them. Why not buy less of a more durable container?

cheers

And we cant use the usual iodophor / starsan / <insert other sanitiser here> why?

So thats 2.25 cents, ++, the caps should come in at around 3-5 cents ++, worst case is 7.25c, about 8 cents including GST, plus freight.

If you can do them for 10 cents each, landed, I'm up for 2000. 3K if you need the numbers.

With all due respect these are the ones to get --- Linky
Ausdaub did an excellent job of obtaining & sending us these tubes. :beerbang: I am very, very happy with these.

I would be interested if these were available for a bulk buy.

I use tubes made by Sarstedt Australia at work they are graduated to 50mL in 5mL steps, they are made from HDPE we heat these past 120C as part of our process. I would guess they are 80mm long and 25mm across. And they have a point bottom.

We buy them science supplies australiaI don't know the price.

I have some similar containers waiting for me at the post office from ProSciTech. They're model number LP9025-UU, $19 per 50. Quite a bit pricier than a bulk buy, but straightforward.

Because when dealing with such small quantities of yeast for storage and stepping up, you need to minimise if not prevent contamination completely. Bacteria will multiply 10 times faster than yeast. Rememeber that they multiply by binary fission meaning an exponential scale.

Yeast farming requires the use of a sterile field.

$19 per 50 is OK, but I'd be wanting 20mL size minimum.
Glass or whatever, I don't have an autoclave, but at the current pricing of the plastic units I'll chance it with the sterilising.

The $19 per 50 ones I mentioned are 30ml. PP container and lid, so they're autoclavable/pressure cooker-able.

I think we have a winner.

Bugger using them for farming yeast...


Start cracking on about how to copy 'White Labs' labels and we get a brew day with Dr Chris White - PERMANENTLY!!!!

 

[Franko]

no worries

Because that would be sanitising, not sterilising...

How does Whitelabs sterilise/sanitise before packing? Doc, you went to their plant didn't you?
