Hi! We have released a new product to the Pioreactor family: the Pioreactor 40ml!

Congrats! Great work guys 
This is really cool - thanks!
One quick question - I noticed there’s an autoclavable vial holder for 20mL vials:
However, is this compatible with the 40mL vials? Or is there a 40mL specific one coming out later?
Thanks!
Victor
Also - the Temperature Expansion Upgrade Kit is only compatible with the 20mL Pioreactor, right?
Do you know if there will be a 40mL version of that some time as well please?
Thanks,
Victor
Yes, this is only compatible with the Pioreactor 20ml. We have a solution later this year for the 40ml.
This can be used with the 40ml, but it’s pretty top heavy, so I wouldn’t recommend it. Again, we’ll have a native 40ml solution later this year (maybe soon!)
I was wondering if there’s been any update on this? I noticed that the upgrade kit for the 20mL is no longer available, but I can’t find any announcement or forum thread on the topic.
Perhaps v1.5 makes the expansion kit unnecessary?
Hi @KarstenSkogs,
Good point: no announcement was made. We quietly discontinued the Temp Expansion Kit (we have some in the office still if really needed). The stacking HATs idea, while fun and cute, wasn’t a cost-effective solution. It also changed the geometry of the Pioreactor too much (i.e. needed longer cables, made upgrades harder, etc).
For the v1.5, we actually have another solution we’ve been planning that skips the in-situ probe. More details in the new year!
Thanks for the quick response!
I’ve been planning a new array, and some of the feedback I’ve gotten for our existing unit is that the temperature response times are too long, especially since it is sometimes preferred to add 1-5mL of cold reagents at a specific time, and the data soon after the addition is of the most interest. I have been thinking of a system for preheating the air supply to the array, which may help the temperature deviations, but with this information, I’ll probably wait to see what’s in the pipeline.
Hi @KarstenSkogs,
In our experiments, we have been diluting 2-12 mL cold reagent. However, we never experienced long response time, in fact it was immediate in most of our experiments. One question I had in mind is whether you tried to modify the config.ini Kp parameters at the [temperature_automation.thermostat] and if you did, how was your experience?
In our case, modulation of the Kp parameters was a successful solution to modulate the response time.
