00:00If you've ever had a dialysis bag burst and ruin days of bench work,
00:03you know that picking reliable tubing is a huge deal.
00:07Today, we're looking at the top 5 dialysis bags for protein purification,
00:11and I've tracked down the best deals online so you can get clean buffer exchanges without
00:15blowing your lab's monthly budget. Kicking things off at number 1 is the
00:19MW-1000 Regenerated Cellulose Tubing. The standout feature here is that extra-tight
00:25cutoff combined with multiple width choices from 25 all the way to 77mm, making it unmatched for
00:32retaining tiny peptides and oligos. At just $12.90, it's worth picking up because low-molecular
00:39weight membranes are usually expensive, but this one delivers reliable retention without sample
00:44leakage. Next up in the second spot is the MW-8000-14000 Regenerated Cellulose Tubing.
00:51This is your classic, everyday workhorse membrane designed for standard recombinant proteins,
00:57antibodies, and routine desalting. Priced at an ultra-affordable $12.76 and sporting a stellar
01:044.9-star rating, it's worth every penny because you get low non-specific protein binding and
01:09consistent pore size at a fraction of name-brand costs. Number 3 is this 5-meter roll of regenerated
01:15cellulose tubing, which gives you options for 3,500, 7,000, or 8,000-14,000 Daltons.
01:22The real selling point is getting a continuous 5-meter bulk roll, giving you the flexibility to
01:28cut custom lengths for any tube or beaker setup. At $30.79, it's totally worth buying if you run
01:35high-throughput purifications and want to slash your per-prep expenses while keeping reliable tubing on
01:40hand. In the fourth spot, we have the MW-3500 Regenerated Cellulose Tubing. What makes this
01:47one shine is its combination of a 3.5-cata cutoff with multiple diameter options, letting you match
01:53your bag's width directly to your sample volume to minimize dead space. Sitting right at $15.58,
02:00it's a smart buy for mid-sized proteins and post-enzymatic cleanups where you need high recovery
02:05and zero hassle. Rounding out the top 5 is this 3,500 Dalton promotion-grade dialysis membrane.
02:12Its best feature is the exceptional membrane uniformity and clean material finish,
02:17backed up by thousands of orders and an impressive 4.9-star rating.
02:21Coming in at $20.93, it's worth the slight premium if you're doing sensitive downstream work
02:27like structural assays or crystallography where background contamination simply isn't an option.
02:32All the direct links to these dialysis bags are waiting for you in the description below so
02:37you can grab the right cutoff for your bench. If this breakdown saved you some research time,
