Help brewing L carnitine

[Walter Hype]

I make pipless L-carnitine 500mg/ml regularly, from bulk supplements.

264 ml distilled water ( heated /mag stirrer)
5ml HCI
Slowly add 250g L-carnitine bulk sups
( let stir for a few minutes will be a lil cloudy)
Add 5 ml BA
Add distilled water until you hit 500ml staring the entire time.
Filter through 22um filter (I use buchnar funnel with medium filter its actually a 20um) comes out crystal clear and ph is around 6-7

If you want to stick to something similar to the funnel idea but actually safe and sterile

Use a stainless steel clasp style

Buy 5 of them or more. They are great. Will never break. The filter is clasped using a special gasket and stainless steel plate. Zero bypass risk. Can be autoclaved. I use autoclave bags. Can put filter inside and just go to town. Can stack a pre filter on top if needed.

Accepts 47mm filter paper is readily available

PTFE is my preferred choice but I also use PES when I want water based.


Throughput is high and if your able to be quick and aspeptic you can hot swap filter paper but I tend to just swap funnels instead. Safer. Buy a few. They are very useful.


Your bottle top filter is fine however for water based. But if you do steroids I really recommend this. Many benefits going this route. Did I mention fully 316L stainless across the entire filter path?
