Waters Corp CORTECS Premier C18 VanGuard FIT Column, 2.7 μm, 2.1 mm, 150 mm
These general-purpose, high-efficiency columns are based on a solid-core particle, offering balanced retention for acids, bases, and neutrals at low and mid-range pH. They incorporate MaxPeak High Performance Surface hardware technology, which significantly reduces unwanted analyte/surface interactions that can lead to poor peak shape and losses in signal intensity. The column design protects the column from contaminants and increases column lifetime.
- MaxPeak High Performance Surface hardware technology.
- VanGuard Fit column design.
- Solid-core particle.

Med Vet International Aspir-Guard, Small, 3/Pack, J1494A
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.
