Syringeless Filters

Syringeless Filters provide a faster and easier way to remove particulates from samples being prepared for High Performance Liquid Chromatography (HPLC)/ Ultra High Performance Liquid Chromatography (UHPLC) analysis. In fact, syringless filters allow you prepare samples in one third the time required by other methods. Add up the time savings, plus the money saved from cutting multiple consumables out of the sample preparation process and you′ll see huge benefits for your laboratory. Features and benefits •All-in-one filtration process allows you to process sample loads in one-third the time •Wide range of membrane choices from 0.2 and 0.45 μm pore sizes to meet specific sample application requirements •Compatible with most major autosamplers •Fewer consumables required. Reduce costs by up to 40% Applications Routine HPLC/UHPLC analysis Standard robotics on HPLC Composite assays Content uniformity Protein precipitation Solubility testing Dissolution testing Sample filtration Syringless filters are available for various applications: Autovial syringeless filters Autovial devices are comprised of two parts: a graduated filter barrel and a plunger. The proven design features an integral filter, built-in air purge and a support stand that protects the recessed slip-luer tip. They are available in a 5 mL and 12 mL volume capacity. Features and benefits •Ideal for hazardous samples. Self contained device eliminates risk of filter pop-off •Built-in air purge maximizes sample recovery •Sterile option available to maintain sample integrity •Unique prefilter design for difficult-to-filter samples Mini-UniPrep Syringeless Filter Mini-UniPrep is a preassembled filtration device consisting of a 0.4 mL capacity chamber and a plunger. The plunger contains a filtration membrane at one end and a preattached cap/septum at the other. The plunger is pressed through the sample in the outer chamber and positive pressure forces the filtrate into the reservoir of the plunger. Air escapes through the vent hole until the locking ring is engaged providing an air-tight seal. Within seconds the Mini-Uniprep can be placed into any able to contain 2 mL vials for injection into your instrument. The device can be used either manually or with a compressor unit. The multi-compressor can process up to 6 samples at one time, further improving sample processing time and reducing the risk of hand stress. The Mini-UniPrep device is designed to fit into any autosampler accommodating 12 x 32 mm vials. Alternatively the septum can be pierced with a needle and the sample drawn off for manual injection into an analyzer. Slit Septa Mini-UniPrep Syringeless Filter For high-throughput automation Features and benefits UniPrep syringeless filters UniPrep syringeless filters are preassembled filtration devices for the filtration and storage of laboratory samples. These devices are quick and easy to use and feature a plunger, filter and vial in one unit. They replace syringe-coupled filtration devices with single, disposable units. UniPrep devices function in a similar way to the Mini-UniPrep. However, UniPrep does not contain a septum in the cap and can be used to filter larger volumes (1 to 5 ml). Features and benefits •Integral storage vial saves time and minimizes laboratory waste •Built-in glass fiber prefilter means even difficult samples are quick and easy to prepare •Choice of membranes for wide sample compatibility
