For product availability, please fill out this form.

The Tandem cartridge with t:lock comes equipped with the latest insulin delivery technology by Tandem Diabetes Supplies, a trusted brand that makes cutting-edge products. Designed with a pouch inside of the t:slim cartridge instead of a syringe, and featuring the brand's patent-pending Micro-Delivery Technology™, this innovative cartridge allows maximum capacity in the most compact size. This cartridge is made to be used with t:slim Insulin Pump System supplies.

Please note that Tandem's t:lock insulin cartridges are only compatible with infusion sets that feature the t:lock locking mechanism. These cannot be connected to other infusion sets.

The design of the t:lock Connector is based on the customer's feedback about the process of filling the infusion sets with insulin. This updated design minimizes the amount of time it takes to fill the infusion sets and also reduces the amount of insulin used in the fill process by 4.4 units. The look and functionality is comparable to the original Luer-lock connector.

t:slim X2 3mL Cartridge Features:

  • T:lock Connectors boost the speed of the insulin-filling process.
  • Reduces time needed to fill the infusion set by 30 seconds.
  • Reduces the amount of insulin used in the fill process by 4.4 units.
  • Compatible only with the Tandem t:slim Insulin Pump System.
  • 3mL cartridge.
  • MPN: 1000727.
  • Box includes 10 cartridges.

T:slim Cartridges

Item received on time and in good condition. This order the items were not in a box but were in a flat container with a peel off lid. Everything was included as always and possible a more sterile process. Very happy.

Usually works okay

The needles packed with the syringes get plugged up about 30% of the time. I end up using a new needle to get the cartridge filled.

Tandem supplies

ADW has been an absolute life-saver for me. It was a nightmare trying to order insulin pump supplies until I found them, but once I did, I've had no issues at all with having my orders delivered on time and with all of my necessary supplies. I am so grateful for this incredible company, they truly have made ordering the equipment I need a walk in the park - thank you so much!

Great Service

Very speedy delivery and service - easy to order in the app when my son is getting low on supplies before his prescription renews. Has definitely saved us on a couple of occasions. Highly recommend!

Lifesaver

About a year ago my doctor's office was in disarray and I couldn't get my pump supplies approved by them for my provider. I was almost out of supplies and had to find a company that I could buy them outright from. ADW saved the day. Very prompt service and zero hassle.

A blessing!

ADW is a great blessing. Couldn't find a more affordable price for tandem pump supplies and G7 sensors for my son. Being single mom, low income and no coverage, every dollar counts.
