Safety in the Lab

Safety matters. And in the lab, safety matters a lot.

However, selecting the safest type of labware for an application can be overlooked.

With more than 100 years of commitment to innovation across our business, we have created a wide range of products designed to improve lab safety, protecting you, your colleagues, and the materials you are working with.

Our lab safety products are divided into several core categories, each with their own safety benefits. To make key safety attributes easy to identify we have also introduced four safety badges.

Our Built Stronger badge is assigned to products with greater levels of robustness and durability.

Our Safer Handling badge is assigned to products that are easier to handle and use during day to day lab work.

Our Spill Protection badge is assigned to products that reduce the risk of accidental spills or leaks.

Our UV Protection badge is assigned to products that protect contents from UV light damage.

About Pyrex™

x

Originally developed in 1908 for use on the American railroads, PYREX™ borosilicate glass was designed to overcome a problem with train lanterns requiring a glass that could handle changes in temperature. The heat of the lantern flame conspired with the cold air of winter to shatter traditional glass lanterns.

Quickly realising that the superior thermal and chemical resistance properties of PYREX™ borosilicate glass made it the ideal material for use in laboratory glassware, Corning Inc. registered the PYREX™ brand name and went on to produce the first PYREX™ laboratory glass items - beakers and flasks - in 1915.

DWK Life Sciences continues to produce PYREX™ laboratory glassware under licence from Corning Inc., using traditional glassblowing techniques and the latest glass production technology.

Thanks to its revolutionary thermal properties and chemical resistance, PYREX™ continues to be a trusted tool of scientists around the globe.

About Quickfit™

x

First developed in 1934, Quickfit™ ground glass joints were designed as an alternative for scientists using rubber bungs, as well as glass and rubber tubing, to connect pieces of glassware.

Today, Quickfit™ jointed glassware is manufactured at DWK Life Sciences’ production facility in Stoke-on-Trent , U.K.

Quickfit™ glass items are manufactured exclusively from PYREX™ borosilicate glass which has a low coefficient of expansion that makes it ideal for use over a wide temperature range. PYREX™ is also highly resistant to chemical attack making it suitable for use with most acids, alkalis, and organic solvents.

Quickfit™ products surpass the requirements of ISO 383 and DIN 12242. A two stage grinding process ensures the formation of a precision 1:10 taper and super-fine surface finish.  This results in joints with an exceptionally good seal and a greatly reduced risk of joint seizure.

Unlike other joints, Quickfit™ sockets feature a rounded rim profile. This round design gives extra strength to the joint and is less prone to chipping than a square rim profile.

Liquid Handling and Media Preparation

In this fundamental but crucial step culture media and other reagents such as phosphate buffered saline (PBS) are prepared. The laminar flow cabinet must be cleaned to ensure sterility and a suitable container for media and reagent storage is needed.

 

Cell Maintenance

During this step, cells are transferred into the laminar flow cabinet and are passaged into a new culture vessel for further maintenance or use in a cell assay. Centrifugation is generally used to remove and refresh expired cell culture media.

Cell Incubation

The incubation step gives cells time and the optimal environment to facilitate cell proliferation. Incubation is typically performed over multiple days or weeks at 37°C. Cells will be inside a culture vessel held within an incubator during this stage. In the case of roller bottles, roller apparatus would also be required.

Cell Cryopreservation

The aim of cryopreservation is to freeze cells in liquid nitrogen for later revival. Expired media is removed through centrifugation and the cell pellet is resuspended in a solution containing DMSO. Cells are then transferred to a cryogenic vial which is designed to safely house cells in liquid nitrogen.

Analytical Sciences

In analytical science, there are a variety of analytical methods that can be used to elucidate the structure or monitor the reaction of a substance. NMR spectroscopy, as well as the various methods of chromatography, are the most commonly used methods.

In order to achieve the best possible working and measuring results, you need high quality glassware and equipment. As a leading manufacturer of laboratory glassware, DWK Life Sciences has an extensive range of products to meet your needs.

Nuclear Magnetic Resonance (NMR)

Nuclear magnetic resonance spectroscopy (NMR spectroscopy) is a spectroscopic method to elucidate the structure of molecules and compounds. Due to electronic interactions of single atoms with the neighbouring atoms, structural conclusions can be drawn. In addition to structure elucidation, the concentration and dynamics of molecules can be determined with this method. This analytical method requires very precise tubes with a constant diameter, a uniform wall thickness and excellent straightness across the entire tube. DWK Life Sciences offers an extensive range of NMR tubes and accessories for this method.

 

Chromatography

The aqueous separation of substance mixtures due to their interaction with a stationary phase and the associated distribution of the individual components is called chromatography. In combination with other analytical and separation methods, the individual components of a sample can be isolated and finally detected. WHEATON offers a wide range of chromatography vials and accessories. The vials are designed for trouble-free operation in most autosamplers. Products include, for example, 12mm x 32mm autosampler vials, headspace vials and shell vials. For use in GC and HPLC applications, the vials are offered with crimp, snap/crimp and screw caps. To ensure chemical compatibility with your sample, DWK Life Sciences offers a variety of different cap and septum materials.

Thin Layer Chromatography

One of the best-known chromatographic separation methods is thin-layer chromatography (TLC), which can be used to isolate individual components of a mixture of substances both qualitatively and quantitatively. The stationary phase (silica gel or aluminium oxide) is applied to a carrier plate, to the lower end of which the sample to be separated is applied selectively. Placed in a vessel with the mobile phase, the liquid rises up the plate. The sample is separated due to the different affinities of the individual components for the stationary and mobile phases, which are thus carried along to different extents in the mobile phase. The product range offered by DWK Life Sciences includes a variety of TLC chambers and jars as well as capillary tubes and other TLC accessories.

BOD Determination

WHEATON BOD bottles are ideal for incubating dilute samples of wastewater, sewage, polluted waters and industrial waste to determine the amount of oxygen required during the stabilisation of degradable organic matter by aerobic biochemical processes. DWK Life Sciences supports this special application with a selection of tubes and accessories.

    Volumetric Analysis

    The exact measurement of volumes is a daily routine task in the laboratory. This makes it all the more important to ensure the quality of the instruments required for this purpose, from volumetric flasks to stoppers, day after day, for every analysis over the long term. Volumetric instruments are integral parts of laboratory glassware that enable the precise measurement of liquids. This ensures high reliability and reproducibility of the measurement results. All DWK Life Sciences volumetric instruments are manufactured to the highest possible standards and meet or exceed the most stringent ASTM and ISO regulations as well as the tight tolerances required. Our range includes a variety of volumetric flasks and cylinders, pipettes and burettes as well as accessories.
