OPTI-GUARD® 1mm Biocompatible Guard Columns set the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OP…

The OPTI-GUARD® 3 mm Columns maintains the tool-free connectivity of the OPTI-GUARD 1 mm, but incorporates a cartridge based format to allow for a larger bed with more capacity. The two-part holder is designed for use with any analytical column to provide vital protection from dirty samples and strongly retained contaminants. An auto-adjusting stem conforms to any tube stop depth for a perfect zero-dead-volume connections.Key…

OPTI-SEAL® Piston/Plunger Seals are the longest lasting seals on the market. Machined from either of two proprietary polymer blends, UHMW-PE or ITB, Optimize Seals provide the ultimate in high pressure sealing capacity. For mostly aqueous buffered mobile phases, OPTI-SEAL® UHMW-polyethylene is the wisest choice. Specially designed to be more resistant to abrasion and wear than standard polyethylene seals, they can last up to s…

Optimize realizes that your time is valuable and should not be wasted worrying about fittings. For this reason, all Opti-Lock Fittings are precision machined in the USA for optimal quality and thread consistency. The machining process is the best way to ensure tight manufacturing tolerances and minimal product variance. What does all this mean? It means that every fitting you purchase from Optimize will perform just as well as…

Optimize Back Pressure Regulators utilize an active mechanism to maintain steady back pressure across a range of mobile phase viscosities and flow rates. Placing one downstream from your detector will prevent solvent decompression and bubble formation in the flow cell, reducing baseline noise and drift. Each pre-set Optimize stainless steel Back Pressure Regulator offers a 100µL internal volume and includes fittings for immedi…

Optimize Replacement Pistons/Plungers are, by design, a consumable part of the HPLC pump and should be replaced on a regular preventative maintenance schedule. To maintain peak performance and avoid unplanned downtime, sapphire pistons require inspection every six months with yearly or as-needed replacement. Optimize sapphire pistons offer optimal concentricity and resistance to wear. Each sapphire rod is specifically cut in r…

The OPTI-LYNX™ Quick Connect Filters allow you to connect any 10-32 valve/port for trapping or analytical column for pre-column filtration. With OPTI-LYNX™, accessing and changing the insert takes only a quarter turn. Replace traps, filters or change configurations in seconds, without tools. OPTI-LYNX™ traps and filters (ordered separately) come in several bed volume/ diameter/ porosity combinations, allowing you to find your…

The OPTI-LYNX™ Quick Connect Trap Columns allow you to quick-connect to any 10-32 valve/port for trapping or analytical column for pre-column filtration. With OPTI-LYNX™, accessing and changing the insert takes only a quarter turn. Replace traps, filters or change configurations in seconds, without tools. OPTI-LYNX™ traps and filters (ordered separately) come in several bed volume/ diameter/ porosity combinations, allowing you…

The OPTI-LYNX™ QuickConnect Guard Column is a high-performance, cartridge-based guard system, suitable for use with any 10-32 analytical column due to its auto-adjusting ZDV port adapter. OPTI-LYNX™ combines effective column protection with the convenience of quick-connect operation. Some cartridge-based guard column products offer convenience with a price: higher internal volumes. Optimize Technologies, refuse to compromise p…

The EXP Ti-lok Fitting features a two-stage locking mechanism ideal for PEEK-clad or sleeved fused silica, such as PEEKsil™ tubing. The two-stage fitting features a patented auto-adjusting titanium hybrid ferrule that seats in any port. The titanium collet locking mechanism provides a second grip point to even the pressure load over the tubing and not crush the silica. The incorporated rear collet locking mechanism is not remo…

Target Sufficiency® is the ability of a target system to respond to a therapeutic. It reflects the abundance and forms of the drug target protein, as well as other key system proteins that connect the target to disease phenotypes and enable response. Assessment of the target system requires an analysis platform that can simultaneously capture multiple precise protein measurements.

The ÄKTA ready™ 450 chromatography system is single use and has a  low flow rate and hold-up volume for efficient purification of small quantities in a GMP environment. 

The ReadyToProcess WAVE 25 rocker features integrated temperature sensors and load cells, designed for convenient handling and control of cell cultures up to 25 L. A filter heater is delivered with the system.  

The TT24-7 continuous air/gas monitoring system incorporates two electrically-cooled traps which operate in tandem to ensure 100% data capture.   The TT24-7 thermal desorption system is a robust, transportable thermal desorption unit, convenient for installation onsite or in mobile response vehicles as well as conventional laboratories. The TT24-7 interfaces to GC(MS) or process MS technology and incorporates two electri…

ACTI-VOC™ is a robust low-flow pump for sampling vapour-phase organic compounds (VOCs) onto sorbent tubes for subsequent analysis by thermal desorption (TD). Being lightweight, easy-to-use and intrinsically safe, ACTI-VOC is ideal for personal monitoring and a wide range of other air and gas sampling applications. Optimised for thermal desorption tubes Unlike other personal monitoring pumps on the market, ACTI-VOC is optimised…

Thermal desorption sorbent sampling tubes for air sampling. Backed up by fast and friendly service, Markes’ tubes provide optimum sampling and analytical performance. Our range includes everything from cost-effective packages of industry-standard tubes to the last word in sorbent tube innovation. Features: Our industry-standard (3½-inch (89 mm) long x ¼-inch (6.4 mm) o.d.) sorbent tubes are available in stainless stee…

Accurate and repeatable gas flow measurement. Accurate and repeatable gas flow measurement is fundamental to obtaining good results from your thermal desorption-gas chromatograph. The traditional bubble flowmeter, relying as it does on the reaction time of the operator, is a potential source of error.The digital flowmeter eliminates this source of error and makes gas flow easement easier and more accurate. The flowmeter allow…
