HPLC Guard Columns and Cartridges
Mac-Mod Evosphere C18/AR, 100 Å, 5um, 21.2 x 10 mm Monodisperse Fully Porous Guard Cartridge
Evosphere UHPLC and HPLC columns are 100 A Monodispersed Fully Porous Silica-based columns designed to combine the benefits of Fully Porous and Core-Shell particle technology into an improved particle design and morphology that brings cutting-edge loading capacity to ultra-high-resolution particle columns. The Monodispersed Particles provide similar efficiency to Core-Shell products when comparing them directly via particle size matching and significantly increase loadability which allows ultra-high resolution analytical separations to scale to preparative separations for isolation work if needed. The bonded phase chemistries are exciting as well to maximize selectivity with novel C12 bonded phase, 2 multi-modal C18/AR, and C18/PFP bonded phases, an extended and stabilized phenyl funtionality in the Diphenyl bonded phase, a polar endcapped AQUA phase, a Phenyl-Hexyl phase, a propyl PFP phase and the RP18-Amide bonded phases which is great for doing bases at low pH.

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.
