A viscometer great for the analysis of drug and biological samples
The viscosity of chemical and biological samples is important to know in several research, clinical, and QA scenarios. Professionals working in life sciences, medicine, and pharmaceuticals will be elated to know there is a viscometer capable of measuring low-viscosity samples, handling very small volumes, exerting minimal shear stress, maintaining sterility and gas atmosphere, and much more!
KEM’s EMS-1000S measures viscosity by quantifying the rotational dynamics of a sample-immersed spherical probe spun using Lorentz forces. The instrument has a wide measurement range of 0.1 to 1,000,000 mPa·s (cP), measuring with high accuracy and repeatability even at super-low viscosities. It provides convenient measurement modes for determining the concentration, temperature and shear rate dependence of viscosity. The
instrument’s heating/cooling system quickly and stably controls sample temperature to between 0 and 200°C.
The EMS-1000S-compatible sample tubes (and probes) can be autoclaved to prevent biological contamination, handy for sample reuse. Tubes can be hermetically sealed to maintain a certain gaseous atmosphere such as nitrogen-saturated, anaerobic, etc. Samples down to 90μL in volume can be measured, great for scarce and expensive samples. Contact-free measurement means no clean-up, making it safer and improving operational effi ciency. The EMS-1000S is extremely user-friendly, just insert the tube, close the lid, and press start.

Biopharma assay developers and clinical research labs face the ongoing challenge of balancing effi ciency, cost-effectiveness, and result accuracy. Multiplexing, or maximising the number of targets per sample, is a key strategy to achieve these goals. Thermo Fisher Scientifi c’s new Applied Biosystems™ TaqMan™ QSY2 probes facilitate this process by demonstrating improved assay performance retention during the transition from single-plex to six-plex assays. This advancement empowers researchers to develop multiplexed in-house assays faster, unlocking the full potential of their qPCR instruments.
The TaqMan QSY2 probes feature a novel quencher design that enhances signal-to-noise ratio and reduces background noise, particularly with TaqMan 5’ nuclease qPCR probes. Equipped with Cyanine 5 and Cyanine 5.5 long wavelength dyes, these probes allow for multiplexing in the far- red spectrum, enabling advanced target detection capabilities. Comparative studies have shown that TaqMan QSY and QSY2 probes outperform their counterparts, offering greater sensitivity, a broader dynamic range, and better performance retention when scaling from single-plex to six- plex assays.
Manufactured in ISO 13485 certifi ed facilities, the new TaqMan QSY2 probes provide healthcare and biopharma assay developers with confi dence in target detection, ensuring unmatched accuracy and reproducibility. Applications for these probes include microbial pathogen detection, monitoring impurities and fl uctuations in bioproduction processes, and gene expression studies.
With features such as increased sensitivity, brighter signal production, and effi cient scaling to multiplex assays, the TaqMan QSY and QSY2 probes enhance assay performance while optimising effi ciency in assay development. Thermo Fisher’s commitment to providing accurate and reproducible results is further underscored by the availability of a full portfolio of dyes and quenchers for maximum assay design fl exibility.
