Liquid Level Detection: why your pump needs a sixth sense

By David Wold

Taste, touch, sight, hearing, smell…humans rely on five exquisitely powerful senses to negotiate even the most mundane tasks. Liquid handling robots don’t have that luxury; they are required to perform repetitive, high-precision tasks more accurately and reliably than humans could ever manage. Choosing pumps with inbuilt sensors for liquid level detection (LLD) gives your liquid handling pump the “sixth sense” it needs to avoid costly errors and ensure liquid transfer accuracy every time. Here’s what you need to know about LLD when choosing a pump for your automated liquid handling platform.

A 3-point check to simplify liquid handling syringe pump maintenance

By Maria Liwanag

The syringe pump is the workhorse of any automated liquid handling instrument. A single syringe pump may complete one cycle every second, and as many as 4 million cycles in its lifetime. Keeping your pump syringes and components in top condition will allow them to run smoothly and deliver their best performance. Over time, syringes may start to wear, and therefore volumetric and positional precision and accuracy are likely to decline. Maintenance and replacement will restore its performance.

How pressure sensors are empowering liquid handling monitoring and diagnostics

By David Wold 

The impact of pump pressure sensors on your automated liquid handling pump performance is often underestimated and underappreciated. The saying, “You don't know what you’ve got ‘till it's gone” applies to many things in life – including fluidic pumps. When device sensors are doing their jobs, the end-user will never know, but when the sensor feature fails to perform, the consequences can be costly and catastrophic. Today’s smart technologies empower pressure sensor functionality more than ever. Why are pump pressure sensors essential for automated liquid handling systems? What benefits do they offer? How do they increase functionality and address process security risks?

Pumping up genomics: how to engineer better NGS sample prep systems

By David Wold

With high-throughput genomics impacting every corner of biology, the demand for more efficient Next-generation sequencing (NGS) workflows is growing rapidly. Automating the process of NGS sample preparation is crucial to avoid inaccuracies due to human error, bottlenecks that delay sequencing results, and the additional expense of re-running sequences. What are the most important factors for an engineer to consider when selecting a pump to meet the stringent performance required for an automated NGS library preparation system?

Pumping blood: choosing a liquid handling pump for hematology applications

By David Wold

Today’s hematology labs are faced with escalating demands to deliver robust and accurate blood test results quickly. At the heart of automated diagnostic systems for blood analysis are liquid handling pumps, which must deliver precise and accurate results every time. As well as being reliable, they must also be affordable and easy to maintain. Unfortunately, not all pumps deliver to these exacting standards. What are the most important factors for an engineer to consider when selecting a pump to meet the stringent performance required for a hematology automation system?

How to secure long-term performance of OEM components for automated liquid handling

By Claudio Bui

When you design a complex laboratory automation system or device, every OEM liquid handling component that you integrate into it should be reliable, dependable and expected to perform to the highest industry standards.  Subpar quality is not an option. If the intended use of the system includes critical tests for clinical diagnostic purposes, the consequences of failure or poor performance of liquid handling components could be more costly than you bargained for, including irreparable damage to your company’s reputation and even worse – it could pose serious risks to patients’ health. Integrating components into your system that are reliable and have a durable design should be an essential consideration.

Four common pitfalls to avoid when choosing laboratory automation solutions

By Kevin Moore

When looking to maximize productivity in life science R&D, drug discovery, clinical studies or clinical diagnostics, laboratory automation is a crucial element. You may already have identified great solutions to automate individual applications and steps in your workflows, but unless these systems work together harmoniously, your lab’s overall productivity could still fall short of the mark. Whether your application area involves clinical diagnostics, genomics, cell biology, drug discovery, protein purification or something else altogether, we’ve identified some of the most common roadblocks to successful automation.
