While the 3Rs are a constant with conscientious and responsible researchers, we too are always looking for ways to make our products better for you, and better for the animal. The most recent refinement to our product line is a new and improved two-channel Vascular Access Button™ for mice. There are two versions: one with a felt base, and the other a silicone mesh base.
What's it for?
The two-channel mouse button allows needle-free, aseptic access to two separate vessels in the mouse, most commonly the jugular vein and carotid artery. Common applications include glucose clamping, continuous infusion plus blood sampling and two channel infusion.
Why the change? What's different?
What else is new?
What is happening to the old two channel mouse buttons?
Once the previous generation of mouse buttons are sold out, they will be discontinued and no longer available.
Will my current parts (handling tool, tethers, caps, etc.) be compatible with the new buttons, or do I need all new stuff?
Your old blue VABMG handling tool will not work with the new two-channel button style. However, the new version of the VABMG, which is purple, is compatible with both the old and new two-channel buttons as well as single channel magnetic mouse VABs™, which are not changing. The old red magnetic caps (VABM2C) will not fit the new buttons; you'll need to order the multi-colored and much lighter VAMB2JC-5. All the other current components - tethers (VABM2T/25, VABM2T/25GCY), tether kits (KVABM2T/25), bile loop (VABM2L) - will all work with the new buttons.
When will the change take place?
This change goes into effect as soon as the old parts run out which should be in August-September 2022.
Do my surgical techniques need to change with a smaller button?
These new buttons should actually make the surgery easier for you as you will need a smaller incision in order to implant the button.
Is the price changing?
The button pricing remains the same as the prior designs. The VABMG handling tool price has increased due to material cost increases unrelated to the design change.
