[labnetwork] HSQ Alternatives

[Chang, Long]

Hi All,

I’m looking for HSQ alternatives since it’s expensive, has a 14 week lead time and comes in 250mL bottle. We waste most of the bottle due to it’s 6 months shelf life. Although we had some bottles still good after 2 years at 5C, it’s just a huge gamble after a year. We tried LN2 freezing, but it takes too much effort.

I’ve attached a table of the cost per mL for the alternatives I found assuming you want 100nm thick. The AQM and EMResist are in powder form and advertise 1 year powder shelf life and 3 months mixture shelf life. They can distribute the powder into many small bottles.

Particularly interesting is the Medusa 82 which has the lowest cost and advertises better shelf life. Does anyone have experience with these HSQ alternatives?
