To support healthy rabbits, the total weight of both the pump and the filled reservoir must be less than 10% of the animal body weight. If you cannot find a pump that meets this requirement, while also meeting the volume and flow rate requirements for your study, remember that tethered infusion is still an option.

• Extremely lightweight pump is only 141g (not including the filled reservoir)
• Flow rates from 0.01-35mL/hr
• 50mL Reservoir
• BlueTooth + Software Option
• Small footprint (84.5 x 55 x 42mm) makes it easy to center on the animal
• Ideal for: this versatile pump is good for animals in a range of sizes, including rabbits that weigh 2kg or less. With flexible flow-rates, and optional software, it's ideal for standard infusion as well as group housing studies.

• Same weight and dimensions as the SAI 3D Mini, but with smaller reservoir and lower flow rates
• Flow rates from 0.005-5mL/hr
• Suitable for rabbits <2kg
• 20mL Reservoirs
• BlueTooth + Software Option
• Ideal for: CNS studies. This pump is our smallest available due to the small syringe size. It's great for studies that require very low flow rates, such as those used for dosing in the ventricular system for CNS delivery.

• Small and lightweight at 382g
• Can only be used with large rabbits >4kg
• Flow rates from 0.1-125 ml/hr
• 50, 100, or 250mL Cassettes
• Rental Option Available
• Ideal for: Labs that use a variety of species. It can be used for everything from large rabbits to full size pigs. The range of flow rates and high volume options make it an excellent overall laboratory pump.

How to externalize the catheter is an important, but challenging decision. The most common options include Vascular Access Ports (VAPs) or a luer hub on an externalized catheter. Miniaturized Catheter Access Ports are also growing in popularity for large animals after being originally developed for rodents.

• Our most commonly used rabbit VAP is our P.A.S. Port Elite due to the low profile
• VAPs are situated under the skin
• A non-coring (Huber) needle is required to access the VAP without causing damage
• Ideal for: Long term studies with intermittent access, especially if there are several days between access. VAPs are also perfect for studies that require group housing; since the port sits below the skin, it is protected from damage

• Hubs are easy to swab for clean access
• Luer Injection Valves (LIVs) can be accessed with a slip tip or luer-lok syringe- no needles required
• Ideal for: Shorter term studies. The catheter externalizes outside of the body and this makes it more vulnerable than a VAP. However, externalized catheters can be easier to use for repeated access studies, even if they are long term, since they can be easily accessed. The Luer option is the common approach for Ear Vein Catheterizations.

• 1, 2 and 3 port options available
• SAI buttons incorporate a smooth barb at the catheter connection- this creates the most reliable catheter-to-button connection
• Ingrowth cuff promotes fast healing and reduces incidence of seromas
• Ideal for: CABs can work for short or long term studies and for repeated or intermittent access. However, since these were developed for rodents, the tubing diameter can be too small for high flow or high viscosity solutions. Please note- at this time, SAI is unaware of the use of this tool in rabbit models, but the CAB has been used in ferrets and minipigs with success.
