[Demelerlab] Cell housing defects

Wed Oct 11 06:57:49 MDT 2023

Borries,
It was nice speaking with you yesterday!  I will pass this information along to our business unit and service team.  I am sure they are going to inquire about the cell housing age.  I assume you likely have a fairly decent amount of cell housing and spare part inventory, but do you know how old these are?  IE- when these particular cell housings were ordered/received?

Thanks,
Nick

Hi Nick, We have a recurring issue with the glue used to keep the key guide inside cell housings in place. The glue seems to degrade/deteriorate over time, causing the key guides to fall out or pop up (see red circle), and when they stick out,

Hi Nick,
We have a recurring issue with the glue used to keep the key guide inside cell housings in place. The glue seems to degrade/deteriorate over time, causing the key guides to fall out or pop up (see red circle), and when they stick out, they prevent the user from inserting window holders or centerpieces, since the end of the guide pin is blocking it -see pictures below:
[cid:image001.png at 01D9FC20.FC94E630]    Pin is still in the key guide slot, but sticking out where the glue has broken down, blocking insertion of other cell components (window holders, centerpieces).

[cid:image002.png at 01D9FC20.FC94E630]   Here the key guide has fallen out completely, cell components can be inserted, but the alignment is not assured, which is critical for the centerpieces of course.

In the past I simply gave these housings to Richard Kanady (San Antonio) who would swap them out for me. I understand he took them back to their manufacturing and they would simply glue the keys back in. I got about 10 of them right now in this state that are currently useless. It would be great if you could swap them out or fix them, we badly need them for multi-sample experiments. I already asked my service engineer (Amit Singh), but apparently there is nothing he can do about this without the serial numbers on the housings, which are curiously all the same:
