This blog post will help clear up some commonly asked questions and give you a better understanding what you can expect to see when handling cuvettes used in cryogenic experiments.<br /><br /><span style="color: rgb(255, 0, 0);">Important</span>: <span style="font-style: italic; font-weight: bold;">All cuvettes</span>, regardless of if they were made for cryogenics or not will eventually crack from the stress. Keep in mind these are glass and glass is fragile! That being said, let's get started.<br /><br /><span style="font-weight: bold;">1. Can cuvettes be used for cryogenic experiments?</span><br />Absolutely! Special care must be taken to ensure that cuvette does not break upon the first usage.<br /><br /><span style="font-weight: bold;">2. What can be done to reduce the chances of cracking?</span><br />Ok this can get tricky. Mostly breakages occur due to the stress caused from either cooling or heating the cuvette. You <span style="font-weight: bold; font-style: italic;">must gradually decrease and increase the temperature</span> or you will have some nice quartz shards to look forward to.<br /><br /><span style="font-weight: bold;">3. Can a cracked cuvette be repaired?</span><br />Sorry to be the bearer of bad news but 99.9% of the time cracked cells cannot be repaired.<br /><br /><span style="font-weight: bold;">4. Why are some cuvettes labeled cryogenic cuvettes while others are not?</span><br />This is simple. The cuvettes that are labeled "cryogenic" are better equipped to handle the dramatic stress from the temperature changes. These cuvettes are welded, which gives the cells additional strength over fire fused cuvettes. Most cuvettes in today's market are fire fused, keep an eye out for this because if you intend to use them for cryogenics say goodbye to your $200 investment.<br /><br /><span style="font-weight: bold;">5. Does NSG Precision Cells manufacture cryogenic cuvettes?</span><br />Good question! Actually yes we do. We are one of the few manufacturers who make these cells.
