Hi All,
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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. </div>
<div><br>
</div>
<div>Particularly interesting is the Medusa 82 which has the lowest cost and advertises better shelf life. Does anyone have experience with these HSQ alternatives?</div>
<div><br>
</div>

<div>Thanks,<br>
