Refractometers come in all sizes, shapes, capabilities, and prices. Some readers may recognize refractometry as a “high school” analysis method or a specialized technique for measuring specific analytes like sugar in water. Increasingly, lab and process engineers employ refractometry to provide quick measures of key quality attributes that under normal circumstances would require much lengthier assays on significantly more expensive equipment.
Check out these quick tips before shopping for a new freezer for your lab
Helmer has released new undercounter refrigerators and freezers that offer secure storage and consistent temperatures to provide safe storage of products while fitting under counters that meet the requirements for ADA (Americans with Disabilities Act) compliant counters.
Freezers and refrigerators are an integral part of any laboratory that requires temperature controlled storage.
It’s official: Sample and standards preparation are significant bottlenecks in highthroughput laboratories, particularly those partly or fully automated. Improved instrument sensitivity—and the need for speed and accuracy—have made sample prep a top priority.
Confidently perform solid-phase extraction (SPE) cleanup of very small volumes with high analyte recovery and clean extracts in low elution volumes that can be directly injected into your LC/MS/MS system.
Assays from academics to industry require shakers. In the life sciences, for example, one expert says the new uses of shakers basically mimic what you see in the industry, which is an increase in the use of genomics. He adds shakers are used in almost every application in some fashion. For example, shakers are widely used in cell culture work.
Atomic absorption (AA) has been known since the 19th century, but it was not until the 1950s, thanks to efforts by Alan Walsh at Australia’s CSIRO research center, that use of AA spectrometers became routine for metals analysis.
Ultraviolet-visible (UV-Vis) spectrophotometry is arguably the most common as well as one of the oldest forms of absorption-based analysis. UV and visible regions of the electromagnetic spectrum are contiguous: UV wavelengths range from 10 to 4000 angstroms; they are visible from 4000 to 7000 angstroms.
While titration is a basic analytical method, titrators are specialized instruments that perform titrations with minimal operator intervention. They can thus minimize errors, improve throughput, and facilitate documentation. There are two major titrator types: potentiometric acid-based designs and Karl Fischer titrators.
Vacuum pumps are an essential piece of equipment and are used in a wide variety of processes in most laboratories. Over the past 25 years, vendors have made significant innovative improvements to vacuum pumps, with important developments in high vacuum technology, corrosion resistance, vacuum control, and improvements in the efficiency and ecological impact of vacuum pumps.
VACUUBRAND’s BVC integrated aspiration station is a safe, convenient system with a small footprint and the power to support two users.
Measuring the viscosity of creamy, pasty or heterogeneous material presents a challenge for rotational viscometers when using traditional smooth geometries such as coaxial cylinder, cone-plate, or simple disk spindles.
Lab workers tend to treat water systems like utility or house water—open the spout and pour it out. That is partly true, as water systems have become ultra-reliable. What scientists often fail to note is how thoroughly lab operations depend on water quality. There may be some leeway in certain operations, such as cleaning glassware that will wind up in an autoclave, but even there, delicate techniques such as atomic absorption and polymerase chain reaction are extremely sensitive to impurities.
After 15 years of constant improvement, S.C.A.T. SafetyCaps belong to the global safety standard in pharmaceutical and chemical laboratories. They enable operators to get solvent vapors under control and create perfect solvent conditions for their HPLC systems.
