A guide to the physical properties of laboratory plasticware and how to use each type safely

Plasticware is required for a variety of laboratory processes but an understanding of its physical properties, and how this impacts compatibility with the chemicals the plasticware has contact with, is essential.

This blog provides an overview of the most common types of plasticware used within the laboratory environment, a summary of the key characteristics of each, and advice on which substances they are most and least suited for.

DWK - Tips for safely heating laboratory glassware

Heating laboratory glassware still requires care, even where products are designed specifically for use in such an environment.

There are a few reasons for this. Firstly, not all laboratory glassware will be of the same specification.

For example, borosilicate laboratory glassware provides a far lower co-efficient of expansion than other glass types such as Soda Lime glassware, which is also commonly used in the lab.

While products in the latter group are still suitable for a range of applications, it is important to consider the chemical suitability of the glass itself when subjecting it to heat.

Secondly, not all laboratory glassware is manufactured to the same quality standards.

Even within a category such as borosilicate glass, the quality of the raw materials used and key factors like the consistency of glass thickness can vary, with premium laboratory and scientific glassware brands such as Duran, Wheaton, Pyrex and Kimble offering more reliable heat resistance.

Finally, the way laboratory glass is heated also has a big impact on safety, regardless of the product used. Here are some tips for safe glass heating to follow in the lab.


Eppendorf - The Tip of the Iceberg: How Pipette Tips Influence Results

There is more to pipetting than the simple transfer of small amounts of liquid.

The exact and coordinated interaction between pipette and pipette tip is of critical importance.

Both components, each on its own as well as together as a system, must meet high quality standards to be able to deliver reliable, precise and reproducible results.

Discover more about the influence of the appropriate pipette tips can have on the pipetting result.

SLS - Kimberly-Clark Embraces Sustainability with The RightCycle™ Programme

Launched by Kimberly-Clark Professional™ in 2011, The RightCycle™ Programme is the first manufacturer-led programme to turn previously hard-to-recycle items into new consumer goods.  

When they created the programme, they began with a simple question: How can we help our customers divert PPE from the landfill and transform it into something new and useful?  

Ten years later, this revolutionary service has helped divert over 1,400 metric tonnes of waste for more than 800 customers.  

Through The RightCycle™ Programme, labs and cleanrooms can reach their sustainability goals, support zero waste to landfill initiatives, reduce waste disposal costs and protect the planet for future generations.  

Products you can trust to be a part of this programme.

How to Use Jointed Glassware Safely

Many traditional chemistry assemblies found in the lab require connected pieces of equipment.

Distillation, extraction, filtration and reflux processes all require various complexities of laboratory glassware assemblies, for example, and while many of the scientists who helped develop these techniques had to resort to custom made glassware, bungs and rubber tubing to connect items, the invention of interchangeable jointed glassware has meant many more - and safer - options are now available.

In this blog, we will look at the various types of jointed glassware available, where each type is most commonly used, and explore some basic techniques for its safe maintenance.


Cut costs, deliver results - Save up to £6900 over five years with CellXpert CO2 incubators

Did you know that running costs for a CO2-incubator easily excel its purchase price over time? Often hidden, costs are significant for regular replacement of fan-associated HEPA-filters or UV lamps, loss of lab space because of low vessel capacity, high gas consumption, or lack of flexibility for future lab needs. Also, increased lab downtime risk and potential sample loss due to unreliable contamination prevention can add significant costs.  

Cut costs, deliver results with CellXpert® CO2-incubators from Eppendorf.

How to Clean Laboratory Glassware Safely

Laboratory glassware has frequent contact with a range of substances on a repeated basis and ensuring that equipment can be re-used safely requires a robust cleaning process. Effective cleaning also helps to prolong the life of the products you used and protects the validity of future work. The act of cleaning glassware for reuse is often referred to as re-processing and can be carried out manually, with the use of automated washing equipment or a combination of both.

This blog outlines the core steps to effective re-processing as well as general tips for cleaning glassware safely.


Webinar: Essentials in Centrifugation - Better Safe than Sorry!

Watch the webinar now available on-demand.

Centrifugation is an ubiquitous method that helps separating mixtures by applying centrifugal force – each application involves different requirements regarding speed, volume or vessel type.  A centrifuge is a device, generally driven by an electric motor, that puts an object, e.g., a rotor, in a rotational movement around a fixed axis. Rotors spin very rapidly and generate extreme forces. It's therefore crucial to understand the principles of centrifugation to proper prepare for your next centrifugation experiment. 

Eppendorf introduced its very first centrifuge in 1964 and revolutionized life science research practices worldwide. With a range of centrifuges that goes from Minispin to Floorstanding Ultras, Eppendorf name remains synonymous with creative design, innovative technology and reliable performance that stand the test of time. In this webinar, they share precious knowledge with you and bring to you all essentials that you need to know for successful centrifugation experiments.  

In this webinar, the following topics will be covered: 

1. Basics of centrifugation

2. Tips & tricks on centrifugation such for different workflows, vessels, rotor types and adapters

3. Things that are good to know before the you go to your next centrifugation such as protocol transfer, safety aspects, aerosols & device maintenance

Watch the webinar if you are a young scientist who is new to the lab. This webinar is also be a refresher for more senior researchers or anyone who is interested in centrifugation.

SLS Raise Over £700 for Rainbows

As usual, we decided to fundraise for Rainbows Hospice for Children and Young People instead of sending Christmas cards last year.  

For the last ten years, many of us have decided to save the money that we would spend on sending Christmas cards to colleagues and instead make a donation to Rainbows Hospice for Children and Young People. The company supports this program with a corporate donation and each year we have been able to offer this incredible organisation contributions of several hundred pounds.  

This year we raised £718, which is a fantastic amount, far surpassing last year's total of £480.

Thank you to all who donated to this excellent cause!

Lonza - Discontinuation of classical cell culture media products in Europe and Africa

During the past years more and more customer increased their consumption of high value cell type dedicated cell culture media for research use provided by Lonza under the Clonetics or Poietics brand. In addition, Lonza could see a trend to serum free chemically defined media for manufacturing purposes.

At the same time, usage of so-called “classical media and buffers” under the BioWhittaker brand declined steadily causing production of small batch sizes and discards for many of these products. As result of these trends, Lonza has decided to discontinue a broad range of “classical Media and buffers” labelled “For Research Use Only” (RUO). Several, but not all of these media will be available labelled “For Further Manufacturing” (FFM). In addition, they are offering custom manufacturing of media for formulations required by customers.
