Med Vet International Aspir-Guard, Large, 3/Pack, J1494C
Prevent accidental aspiration Aspir-Guard prevents fluids and dental debris from being accidentally aspirated during a routine dental procedure. Numerous publications and textbooks state that the standard of care requires the use of a material to block the oropharynx from accidental aspiration of fluids that accumulate during every dental procedure. Aspir-Guard is a dehydrated PVA donut shaped product. When rehydrated, it has a soft gentle sponge like feel. It is placed over the distal end of the ET tube prior to intubation just outside the epiglottis. Attached strings are used to tie the Aspir-Guard to the roll gauze or old IV tubing used to secure the ET tube to the patient. After the patient is intubated, the Aspir-Guard is pushed into place to block the oropharynx from fluid aspiration. Once the procedure is finished, the Aspir-Guard is removed gently together with the ET tube. Three to a package.

Waters Corp Waters XBridge Premier BEH C8 VanGuard FIT Column, 2.5 μm, 4.6 mm X 150 mm
The XBridge Premier BEH C8 Columns provide less retention than C18 columns, facilitating rapid method development. They leverage trifunctionally bonded BEH particles for a broad pH range (1 to 12), excellent low pH stability, and minimal column bleed, alongside MaxPeak High Performance Surface hardware to enhance peak shape and signal intensity. The VanGuard Fit design extends column lifespan by protecting against contaminants.
- Less retentive compared to C18 columns, which is desirable for fast method development.
- Trifunctionally bonded BEH particles offer the widest usable pH range (1 to 12), superior low pH stability, and ultra-low column bleed.
- MaxPeak High Performance Surface hardware technology significantly reduces unwanted analyte/surface interactions, improving peak shape and signal intensity.
- VanGuard Fit column design protects the column from contaminants and increases column lifetime.

Waters Corp Waters VanGuard Cartridge, 450Å, 2.7 μm, 2.1 mm X 5 mm, 3 pk
BioResolve RP mAb Columns contain 2.7-μm superficially-porous-silica particles with an average pore diameter of 450Å. These particles are functionalized with a proprietary polyphenyl bonding process designed for LC or LC-MS analyses of intact IgG monoclonal antibodies and their fragments. This product acts as an all-in-one column protection solution by removing contaminants from the analytical workflow.
- Designed for LC or LC-MS analyses of intact IgG monoclonal antibodies and their fragments.
- Removes contaminants from the analytical workflow.
- Filters out contaminants to prevent them from negatively affecting the analytical column and data.
- Reusable, and a worn one can be replaced.
- Offers the same inner diameter and pH range as the corresponding polyphenyl column, ensuring chemical and mechanical stability.
