[3dem] Gatan model 626 specimen cryo holder

[Sen, Anindito]

Tom (tom at tgstechnologies.net<mailto:tom at tgstechnologies.net>) has fixed our cryo holders, and we have been using the repaired holders successfully for a reasonable period of time. My vote goes to Tom.

I agree with Paul. We've sent both single tilt and double tilt holders and Tom does an amazing job.

Best,

Hi Yael,

I t has been a few years, but you could try Tom Schmelzer (tom at tgstechnologies.net) and see if he is still repairing these units.  I have personally used him multiple times for tip replacements and other side entry holder repairs.  I’ve found him to be very reliable and more affordable than the manufacturer.

I have no relationship with the above mentioned individual, just a satisfied customer.

Best,
Paul

Hi Yael,

We have broken the bin on the Model 626 cryo-specimen holder multiple times. Send it back to Gatan and they will fix it for you, but the cost is pretty high.

Best,

Zongli

Hi All,

Does anyone sell a Gatan Model 626 cryo specimen holder in working condition?

In addition, the pin on our holder broke. Does anyone have experience repairing it or know whether it can be fixed?

Many thanks,

Yael
