Laboratory Glassware

Description Connection System with screw cap and 2 or 3 GL 14 ports, PP, blue/grey Manufactured from Polypropylene Rigid or semi-rigid tubing of different diameters can be accepted by using a blue GL 14 open topped cap with one of the inserts. Available with 2, or 3 threaded outlets (ports). Four different tubing diameters (1.6 mm, 3.0 mm, 3.2 mm or 6.0 mm tubing outer diameter) can be used by changing the GL 14 inserts. By applying positive or negative pressure liquid can be pumped out of or into the bottle via the screw cap. Fully compatible with all the GL 45 threads and therefore highly versatile.

Description DURAN Manufactured from borosilicate glass 3.3 Due to the high wall-thickness of the vessels and the exact machining of the vacuum-tight ground joints on the lid and base, storage under vacuum is possible – even over extremely long periods. To accelerate the drying process, a vacuum can be applied via the stopcock Suitable for full vacuum (0 mbar) Spare parts such as lids, bases, stopcocks and caps can be interchanged as required

Description The DURAN® reservoir bottles have been specially designed for the storage and delivery of high-performance liquid chromatography (HPLC) mobile phases and solvents. Reservoirs have one central cavity for the inlet filter to allow the most efficient delivery of mobile phase to HPLC analyzers. A safer and more convenient alternative to flat bottomed glass media bottles, the conical bottom reservoirs allow a greater recovery of solvent, without having to tilt reservoir and risk solvent spill. The larger reservoirs allow longer, uninterrupted analyses. These are especially useful during a weekend or lengthy chromatographic analysis when there might be a risk of running out of solvents during unattended operation. The optimized conical design allows the safest and most efficient delivery of mobile phase to HPLC analyzers FEATURES & BENEFITS Manufactured from the material of choice for solvent bottles - borosilicate 3.3 glass. This material has an exceptional chemical durability offering a very low inorganic ion extractables profile, and the total absence of any organic extractables. DURAN® is a borosilicate glass type 3.3 as specified by the international standard ISO 3585, and is classified as a “Type I, Class A low-expansion borosilicate glass” as defined by ASTM-E438-1992. DURAN® glass is classified by the USP / EP / JP pharmacopoeias as a “Type I neutral glass” Retrace Code, and certificate for manufacturing lot traceability Available in five useful sizes 1/2/3.5/5/10 Liter. On the two larger sizes, the central cavity can accommodate magnetic stir bars for improved mixing. Side vent / drain hole in the base for ultrasonic bath degassing, or water drainage after cleaning. GL 45 thread fits standard HPLC connection caps. Durable white enamel volume graduations. Autoclavable at+121 °C or +134°C. Applications Mobile phase reservoirs for HPLC. Reagent supply to liquid handling systems.
