Replacement Power cord for VWR 1122S circulator

6 posts in this topic

Hey all,

I just scored a VWR 1122S circulator off eBay and need to find a replacement power cord before I start using it. I believe this circulator is manufactured by Polyscience and modeled after their CLASSIC series.

Does anyone know what I should be looking for in a replacement power cord? I have one here that is marked 10A 125V that fits the circulator perfectly. Would this work?

by 'rating' that cord is a little on the 'lite' side.  the device probably draws 15 A

if you cant find a thicker cord, you can set it up w that cord and after 30 min or so see if the cord feels hot, or overly warm


that would tell you you might want to move up to a thicker cord.

From what I can find this circulator draws 11 amps, I wouldn't feel safe leaving it running unattended using a 10 amp cord.  In the picture I'm looking at the power connector looks like it's the same thing you would find on a computer power supply, if so this one is rated for 13 amps;




If you have a Microcenter in your area they would probably have something suitable in stock, look for a 16AWG cord or thicker.

I went ahead and ordered a replacement cord from Polyscience. For reference it is marked 13A 120V.

      Can anyone illuminate me on the appeal of cooking meat by putting it in a plastic bag and boiling it? I've had this at many a (fine) restaurant and I fail to appreciate the ecstasy at which some seem to undergo when encountering (or offering) this preparation...
      Short of sounding absolutely ignorant, I realize that the technique affords great advantages to some products (like foie gras), but chicken? pork? Tender as they may be, I prefer a more natural way of "sealing" food - perhaps the age-old bladder or other non-porous offal
      I ask only because I wish that I could be "enlightened" and join the swooning masses when offered this preparation at a restaurant...

      I want to make mint spheres for use in a hot sauce. (Think lamb with mint caviar.)   Can this be done? Is it possible to make heat-stable spheres?   What is the most effective way to extract mint flavour from the raw leaves? I don't want the resulting spheres to contain alcohol as it will be served to children. My cursory investigations indicate that glycerol may be an alternative—has anyone done this?

      I recently did some halibut steaks sous vide. They were about 1 1/2  inches thick. I did them for 30 minutes at 122 degrees. When i took them out to brown them, they were very fragile. As I browned them they fell apart. They were delicious, perfectly cooked from an eating point of view, but ugly. Too hot, too long or both?

      Anyone tried this?
      I'm trying to think of something novel to do for my friends at an upcoming birthday weekend. We are renting a house in the Hunter Valley (Australian wine region) and food is a major component of our weekend. Last time I did fizzy fruit—the grapes and oranges were awesome and everyone enjoyed the unique experience. I want to do something quirky like that again.
      The whipping siphon is easy to transport so I'm interested in using it. The siphoned soufflé in Modernist Cuisine, volume 4 page 297, has a chocolate variation that does not require propylene glycol alginate or maltodextrin (I don't have those things in my pantry, yet). That looks like it might be a good one to try. Anyone done that and have some advice for me before I dive in?

      Besides the health concerns, deep frying steak is the best way to get an even colour and crust on steak. In my most recent experiment, I tried the technique of deep frying prior to, and after, cooking the steak sous vide. In the past, I had only fried the meat after it had been cooked.
      The meat was veal chops. As can often be the case, the meat was mishandled somewhere along the way. The obvious signs of this were indentations in the surface. This kind of thing makes it tricky to pan fry and get even colour.

      This soft meat is also tricky to vacuum seal as it can often be further compressed and misshapen in the process.
      I was delighted to observe that a short 45 seconds in hot oil fixed both of these issues! I didn't expect that. Nice. The meat plumped up and that indentation was gone. It also held its shape nicely when vacuum packed.

      Time and temperature matters. The difference can be just a few seconds or degrees. In the next picture, the time was the same but the oil was 20°C hotter for the steak on the left and the crust is noticeably darker. My next experiment will try 30 seconds at 200°C before and after.

      The goal is to keep the crust as thin as possible.

      I hadn't anticipated the secondary benefits of deep frying prior to sous vide. The plumping of the meat and slight firmness made them easy to package and present. I am curious whether anyone has observed this. I am also curious if it would it work in hot water, rather than oil.
