<div dir="ltr">Hi Ani, <div><br></div><div>We've had Stirling SU780XLE, Thermo TSX70086, and Avantor "house brand" units running here at ASU NEON Biorepository over the past 5 years. All have similar energy use ratings, recovery times, warranties etc. Overall performance has been great - in 5 years we've had one unplanned service event. <div><div><br></div><div>Some items we considered - </div><div>Where will the unit be located. Is noise a concern? 110V or 220V power? </div><div><div>Could the freezer need to be relocated for any reason? <br></div></div><div>Is it helpful to be able to run the unit at different temperatures for any reason?<br></div><div>Does a manufacturer offer better "off the shelf" racks etc. to accommodate your specific sample container. Is this system interoperable with other freezers if there is a failure and you need to move samples quickly?</div><div>Is it necessary to eventually standardize to any particular brand or size? These Stirling and Thermo freezers both hold 700 standard cryoboxes but are different storage volumes overall. A different size may be more useful for odd-shaped or irregular sample containers.</div><div>Does the University have a purchasing agreement in place with any supplier? Sometimes we get freebies like racks, extended service agreement, initial setup etc. if there is a promotion.</div><div>Availability of local service vendors specific to that particular freezer.</div><div><br></div><div>Please feel free to DM if you want any other details.</div><div><br></div><div>Thanks,</div><div>Azhar</div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, May 14, 2024 at 11:00 AM Shoobs, Nate <<a href="mailto:shoobs.1@osu.edu" target="_blank">shoobs.1@osu.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<span>Despite all the bells and whistles (including a sleek looking ~smartphone app~ that automatically notifies me of temp fluctations), troubleshooting it was a major pain that involved exporting logs via USB 2.0 port on the unit itself, emailing
them to the fisher reps, and manually silencing alarms from the touch screen on the front door every few hours for a few days.</span></p>

<span><span>Thankfully</span></span><span> it was repaired under warranty, but I’d avoid this model if I were buying another one. If we hadn’t had another lab’s freezer in the building as backup, we would have lost all the recent

<span>We have been very happy with the new iteration of the Thermo Fisher -80 chest freezers. Granted we have not had them for very long (maybe a year) – they were purchased to replace failing older models. They are a lot more efficient in that the
compressors do not run constantly. The freezer shuts down when it reaches temperature and only kicks in again once it warms up by a degree or two. This puts a lot less strain on the compressors and will hopefully mean they will last a lot longer.</span></p>

<p class="MsoNormal" style="margin:0in;font-size:11pt;font-family:Aptos,sans-serif">
<span>Chest freezers are so much more efficient than uprights in holding temperature. Uprights lose so much temperature when the door is opened as the temperature literally just falls out of the freezer. Attached is a quote we received from Fisher
at the end of 2022 for both upright and chest however this includes out considerable University of Kansas preferred supplier discount – maybe UMich has something similar though</span></p>
