Mac-Mod Avantor Prevail Silica, 110 Å, 5 µm, 3.0 x 7.5 mm Guard Cartridges (3/pk)
Avantor Prevail HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. Avantor Prevail HPLC columns are silica based except for Prevail Carbohydrate ES. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes. Avantor Prevail HPLC columns are stable from highly organic to highly aqueous. Avantor Prevail HPLC columns are specialty phases for specific applications. Avantor Prevail HPLC columns provide excellent sensitivity with microbore and ELSD applications.

Waters Corporation Sentry Guard Cartridge, Amide, 3.5 μm, 4.6 x 20 mm
These Sentry Guard Cartridges are designed to retain extremely polar compounds, such as carbohydrates and sugars. They feature a chemically stable, trifunctionally bonded amide phase, stable from pH 2 to 11, for separating polar analytes across a wide range of polarity and pKa.
- Retains extremely polar compounds (e.g., carbohydrates, sugars).
- Chemically stable, trifunctionally bonded amide phase.
- Stable across a wide pH range (2 to 11).
- Separates polar analytes with varied polarity and pKa.
- Protects analytical columns by trapping particulates and strongly retained compounds.
- Ideal for HILIC applications, including sugars, glycols, and polar compounds.
- Compatible with common HILIC solvents (e.g., acetonitrile, water with buffers).

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.
