TFlow Rodent Anesthesia Mask

Simple non-stereotaxic stabilized rodent anesthesia and analgesia mask, equipped with gas-scrubbing port and stabilized base.



Many masks are:

Unstable by design

Instability requires researchers to use tape to hold the mask and tubes in place.
Instability compromises the face-mask seal.

No waste gas port

Many labs use home made masks such as from funnels and cut test tubes, while these can work they have no way of dealing with waste gas.

To Complex

Rubber diaphragms, required stabilizing tape, multiple parts, difficult to clean. These are not necessary for great non-stereotaxic rodent anesthesia.

TFlow has:

Simple stabilized base

The signature "T" base stops lateral and posterior roll.
Magnetized base for simple placement and storage.
Holes for pinning down the mask if that is preferred, and simple taping places if necessary.

Waste gas port

You don't need to have a scrubber (although we suggest it) to utilize this port.
If you don't want to use it, the mask still works perfectly by directing the gas towards the mouse and not allowing it to flow directly through.

Universal and Simple design

Simple cleaning, less breakage, intuitive user experience.
Standard TFlow mask properly fits mice, rats, and hamsters - instead of requiring different masks.

TFlow Specifications

Mask body is made from non-toxic and semi-flexible ABS Plastic resin.

Color of the mask can be added to notes during checkout or through a response email to your order confirmation. Available colors are gray, black, white, orange, and blue.

Masks have dimensions 74mm long by 58mm wide by 18mm tall. The shape of the cone is specifically designed to match that of rats and mice, allowing for all sizes of rodents to work with a single mask.

The magnets are neodymium and with all three, are capable of withstanding about 0.4 pound-force of pull.

Masks have a 200 degree Celsius melting limit and should generally be kept below 140 degrees. We suggest washing your masks with hot water and disinfectant, or using an autoclave that does not heat up above 140 degrees Celsius.
