VWR® has expanded the VWR® carboy features and benefits by offering the Versatile Cap, Versatile Barb and state-of-the-art Spigot technology. These three components complement a wide array of applications supported by the VWR® Carboy. The leakproof cap insert with replaceable gasket enable users to quickly change the top connector of each carboy to match the application needs. Versatile Cap is stackable and is offered in both 83 mm (compatible with most industry carboys) and a 120 mm extra wide-mouth version that fits exclusively on VWR® 20 L and 40 L extra wide mouth carboys. To see homogenisation of solutions, closed adapter inserts with a clear window are available. Quick connect options are also a part of the many capabilities of this Versatile Cap technology. This includes quick-connect port combinations of two, three, and four. For bottom tubulation, Versatile Barb is used to replace the spigot and support flexibility in drainage, connection to a pump or automated equipment, or connection to a filling bell. Sanitary fitting connector is also available in order to enable the carboy to be used as a supply reservoir to a larger system.

These lightweight Standard Line pipettes feature a revolutionary suspension system which allows the shaft to retract slightly when pressed against a row of pipette tips. Each shaft moves independently, resulting in an even sealing force being applied to all 8 or 12 tips. The suspension system not only ensures secure tip sealing, but also eliminates tips being jammed.

PolarSafe Dots are made from chemically inert polyester with a unique adhesive formulated to adhere to laboratory glass and plastic ware. These dots will not only withstand conventional freezing (−80 °C) but can also be used for most cryogenic storage applications (vapour phase nitrogen storage at −196 °C). No need for separate labelling solutions for your cryo-preservation units and your ultra low freezers. The labels can even be used in incubators. PolarSafe Dots do not require self lamination to be effective. The sleeker labels mean your tubes will still fit most storage systems without the label sticking or being torn off. The wide range of sizes allow you to label your whole experiment permanently, from micro-centrifuge tube to cryovial, microtiter plate to storage boxes.

X-Gal is a chromogenic substrate for ß-Galactosidase that forms an intense blue precipitate. Used in conjunction with IPTG in a colorimetric assay, X-Gal allows differentiation of recombinants from non recombinants in cloning experiments with vectors containing the lacZ gene. It is also used in microbiology to detect microorganisms which have ß-Galactosidase activity.

These films are 240 µm thick white vinyl with adhesive, for use with white microplates. Light reflective properties of the film, when used to seal clear bottom plates, maximise the sensitivity of bioluminescence and chemiluminescence assays in bottom-reading luminometers. White films have also been used as a backing matrix for microscopy of punch-out samples from filter plates.

The shiroGEL mini vertical PAGE system is modular, allowing PAGE and electroblotting to be carried out in the same tank, simply by changing the inserts. The system features inserts for each application, and a common buffer tank in which to run them. Each insert has its own electrode assembly, which connects to the lid of the buffer tank. For safety, the power leads connect directly to the lid. When the lid is removed, power is disconnected from the system. The inserts also have a small pad that fits into position in the lid. This ensures that the lid is always properly placed and aids in its removal. The buffer tank is moulded to prevent separation and leaking. A variety of spacers, combs and other accessories are available to customise the system. All spacers and combs are colour coded or clearly labelled to indicate thickness.

Designed for ease of use and safe operation, the shiroGEL horizontal electrophoresis systems and accessories are built to withstand the rigours of everyday use. For leakproof performance the gel boxes and gel trays are moulded from thick acrylic. UV transparent gel trays aid in visualisation of samples. Cassettes protect the electrodes and allow for easy replacement. Gel casting is simple with the durable rubber casting gates. Slots in the sides of the trays allow for easy comb placement. The two-piece design of the combs allows for vertical adjustment, giving the user control over the depth of the well. The combs supplied with the systems are 1,5 mm thick. Multiple combs, including those compatible with multichannel pipettes and different thicknesses, are also available. The 'EasyLift' gel box lid is easily removed using the side tabs and pressure pads. The lid is domed, to prevent condensation from dripping onto the gel, and is surrounded by a drip ring, to help recover the condensate and maintain buffer concentration.
