To use older, open system Medela pump parts with a Spectra, you need to connect the Medela flange connector to your Spectra backflow protector. (If you plan on using both the Medela and Spectra pumps, I’d buy an extra set of tubing here, so that you have one set of tubing for each pump.)ģ Ways to Hack Your Spectra to Use Older Medela Pump Parts Some people are able to just pull the yellow end off. Because the new Medela parts are closed system, you don’t need a separate backflow protector.Īll you need to do is get the yellow end of the Medela tubing off, and then you can attach the Medela tubing directly to the Spectra pump. With Medela’s closed system pump parts, hacking them to work with a Spectra is pretty easy. Using New, Closed System Medela Pump Parts with a Spectra Medela has recently transitioned from their older open system pump parts to newer closed system parts, and the strategies are different depending on which parts you have.
Want to use Pumpin Pals flanges ( more on these here – also, buying an adapter for Pumpin Pals is an option).Prefer a separate flange and connector as it can be easier to attach your flanges and bottles while using a hands-free pumping bra.Were a Medela user before purchasing your Spectra, and you want to continue using your Medela parts and bottles.Hacking your pump might be necessary if you:
However, there are a number of situations where you might want to customize your pumping experience. Why Hack Your Spectra to Use Medela Pump Parts?Īll Spectra pumps come standard with 24mm and 28mm flanges, and now you can purchase additional breast shield sizes separately on their website. I only recommend products I love! More info here. This post may contain affiliate links, which means that if you click through and make a purchase, I’ll be compensated at no additional cost to you.

The CIP algorithm in ChemDoodle is validated against the test suite provided by Hanson et. Stereochemical features in your structures will be assigned "R", "S", "E", "Z", "M" and "P" descriptors. to remove any ambiguities and describe a completely consistent system for CIP assignments.ĬhemDoodle implements all 6 current CIP rules as well as auxilliary desciptors and mancude ring support. The most recent CIP rules from IUPAC were then algorithmically analyzed and standarized by Hanson et al.
These rules were adopted by IUPAC for naming standards and fully described in the Blue books. While flawed, they have seen many revisions over the decades and were clarified by the work of Paulina Mata. The CIP rules have long been the standard for describing configurations of stereochemical features in a molecule.
