AZLON® reusable plastic labware covers a broad range of applications in the modern laboratory. With over 800 products in the range, including storage bottles, wash bottles and volumetric items in a variety of plastic polymers, the AZLON® range encompasses all the plastic essentials needed for traditional science, food and industrial applications.

AZLON® products are manufactured to the highest quality standards utilising a range of plastic moulding techniques including blow and injection moulding to ensure superior product performance. Leadership in polymer science and innovation have combined to make AZLON® one of the most widely known and respected brands in durable laboratory plasticware.

The power of Azlon® patented Driplok® technology

AZLON® vented wash bottles were the first on the market with the discovery of Driplok® technology. The patented Driplok® vapour venting valve prevents evaporation and stops pressure build ups, putting an end to hazardous, costly drips and ensuring an accurate and continuous dispensing stream of liquid, even in the case of volatile solvents.

Don’t forget to combine the Driplok® vapour venting valve with the AZLON® custom printing service, allowing you to design your own artwork for the wash bottle of your choice.

Azlon® for food contact

AZLON® storage bottles, jugs, scoops, measuring cylinders and many more products in the AZLON® reusable plasticware range are suitable for food contact applications in accordance with EU and/or US FDA regulations.


The origins of the MBL® brand date back to the establishment of Morbank Limited in Pontypridd, South Wales in 1949. Morbank specialised in the manufacture of volumetric products manufactured from both borosilicate and soda-lime glass. Through a series of acquisitions, the MBL® brand became part of the DWK Life Sciences glass portfolio in 1987. Comprising of around 300 mainly volumetric products, MBL® is now a well-established glass brand of DWK Life Sciences.

All DWK Life Sciences manufactured volumetric products, including MBL® flasks and cylinders, are tested and calibrated in an ISO/IEC 17025 accredited calibration laboratory located at DWK Life Sciences’s glass manufacturing facility in Stoke-on-Trent, Staffordshire. Although all of our volumetric glassware is manufactured to comply with the relevant ISO or national standard, the ISO/IEC 17025 accreditation offers our customers an additional assurance of the accuracy and precision of our volumetric glassware.

The MBL® volumetric glassware range includes volumetric flasks, measuring and mixing cylinders, pipettes and burettes, all manufactured, tested and calibrated to the highest accuracy standards.

For almost 70 years, MBL® has gained an international reputation for its quality, accuracy and performance - a reputation that continues to this day.

Choose the right level of accuracy for your application

Products in the MBL® volumetric glassware range are available in two levels of accuracy – Class B or Class A/AS. Products calibrated to Class B accuracy tolerances are suitable for general use applications where high volumetric accuracy is not required. Class A/AS volumetric items should be used where higher volumetric accuracy is required, such as analytical applications, as the accuracy tolerances of a Class A/AS item are half those of the equivalent Class B product. MBL® Class AS pipettes and burettes are calibrated to the same accuracy as a Class A item, but the liquid outflow time is faster.

Most MBL® Class A volumetric items are available with batch conformity certification for traceability purposes. These certificates can be downloaded from the Support section of our website. MBL® volumetric and graduated pipettes are also available with individual calibration certificates, which are supplied with the products.


QUICKFIT® ground glass joints were first developed in 1934 by a British company, Triplex Safety Glass Company as an alternative to scientists using rubber bungs and glass and rubber tubing to connect pieces of glassware. Following the Second World War, Triplex established a new company, Quickfit® and Quartz Limited, to produce the new QUICKFIT® jointed laboratory glassware in Stone, Staffordshire as demand for this jointed glassware increased.

In 1958, Quickfit® and Quartz Limited were acquired by James A. Jobling & Co. Ltd. (the U.K. manufacturers of Pyrex® laboratory glassware). In 1973 James A. Jobling and Co. Ltd. was acquired by Corning Inc. and became part of Corning’s European Laboratory Division. The company changed ownership and company name a number of times over the subsequent years, becoming DWK Life Sciences Limited in 2008, following the break-up of Barloworld Scientific Ltd.

Today, QUICKFIT® jointed glassware is manufactured at DWK Life Sciences’s production facility in Stoke-on-Trent, Staffordshire.

All QUICKFIT® glass items are exclusively manufactured from PYREX® borosilicate glass which has a very low coefficient of expansion, making it ideal for use over a wide temperature range. PYREX® glass is also highly resistant to chemical attack and can be used with most acids, alkalis and organic solvents.

QUICKFIT® interchangeable conical joints are made to an accuracy that surpasses the requirements of ISO 383 & DIN 12242. A two stage grinding process ensures that the joints have a precision 1:10 taper and super-fine surface finish, resulting in joints that have an exceptionally good seal with a greatly reduced risk of joint seizure. The excellent surface finish also ensures that the joint will not leak and will be gas and vacuum tight.

Unlike the joints available from other manufacturers, 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.

What type of glass joint do you need?

A number of different joint types are available in the QUICKFIT® range, including conical joints, spherical joints, flange (butt) joints and screwthread joints. Conical joints are the most common type of ground glass joint and comprise a (male) cone and (female) socket.

Most QUICKFIT® conical glass joints are manufactured to comply with European ‘B’ length joint dimensions, as defined in ISO 383. DWK Life Sciences is able to supply many QUICKFIT® products in a range of joint sizes from 5/13 to 60/64.

Whatever the scientific requirement, from the construction of a simple reflux assembly to a complex fractionation apparatus, there is a choice of QUICKFIT® products available to meet that need. QUICKFIT® offers one of the most comprehensive ranges of jointed glassware available, all manufactured from PYREX® borosilicate glass.
