Optimize Technologies EXPGuard Column Cartridge, 1.5mm x 5mm, HILIC, 3µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape. Use with EXP™ Direct Connect and In-line Holders.
Mac-Mod Avantor ACE UltraCore SuperC18, 95 Å, 5 µm, 2.1/3.0 x 5 mm UHPLC Guard Cartridges (5/pk)
Avantor ACE UltraCore solid-core (core-shell) particle columns are ideal for MS work offering improved signal intensity and maximum response. These columns combine high efficiency separations with low back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability. Solid Core particle technology provides higher efficiencies per unit back pressure as compared to sub-2-micron UHPLC columns. Columns combine the proven advantages of UHPLC and HPLC columns with Solid Core Particle Technology. Solid-core columns can be used on both UHPLC and HPLC systems. Excellent peak shape and phases stability with extended pH. Highly inert, ultra-low bleed, designed for use with LC/MS compatible buffers. 2.5 and 5 µm particle sizes available.

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.
