What is a Seal of Quality? There are four levels of Seal of Quality — Platinum, Gold, Silver, Bronze — which are allocated to products based on the number of reviews they receive and the average rating of those reviews.

The latest laboratory instruments to earn a prized Seal of Quality have been announced in recognition of outstanding feedback received from scientists globally.

Seals of Quality recognize the top 0.1% of products that consistently receive the highest customer review ratings on SelectScience® and are designed to help scientists and healthcare professionals worldwide see at a glance the instruments and services their peers recommend the most.

Among the latest to receive a Seal of Quality is the LUNA™ Family of Automated Cell Counters by Logos Biosystems, which has now received well over 200 reviews from scientists around the world, with at an outstanding average overall rating of 4.8 out of 5 stars – making them only the sixth product in history to be awarded a Platinum Seal of Quality since the program was launched in 2017.

The LUNA automated cell counters are designed to offer incredible speed, accuracy, and reliability, and users have been impressed. Mike Licudi, from Imperial College London, left this review in August 2020: “I love the LUNA counter. It's so easy to use and it's fast. Love the fact that there are multiple counting modes and you can set it up to use your custom stains.”

Meanwhile, another cell counter is following hot on the LUNA’s heels: The environmentally-friendly CellDrop™ Automated Cell Counter has been awarded a Gold Seal of Quality, with over 100 reviews at an average rating of 4.8 out of 5.

The first imaging cell counter to remove the need for slides or plastic consumables, the CellDrop was only launched last year by DeNovix and has been receiving rave reviews ever since.

One recent 5-star reviewer of the CellDrop is Sarah Silk, from Oxford University, who writes: “Compact for benchtop and easy to use, with no consumables needed. Excellent customer service and guidance whenever required - highly recommend for quick and accurate counts.”

Another new Gold Seal of Quality recipient is the Mastersizer 3000 by Malvern Panalytical, a laser diffraction particle size analyzer designed to deliver rapid, accurate particle size distributions for both wet and dry dispersions with minimum effort.

One of over 100 reviewers who have shared their opinion the Mastersizer 3000, Sunil Kumar Gahlaut, from healthcare company USV, declares it the “best product to verify the particle size.” He writes: "Best product, best service, 21 CFR-compliant software, accurate and precise results.”

Agilent Technologies has also been awarded a Bronze Seal of Quality for two of its LC systems – the Agilent 1290 Infinity II LC System and the Agilent 1260 Infinity II LC System, which have now each received over 50 reviews at average ratings of 4.3 and 4.6 respectively. The latest awards mean Agilent has now earned a total of four Seals of Quality since the program was launched in 2017 — the other two being awarded to the Agilent 7890B Gas Chromatograph, which received a Bronze Seal of Quality earlier this year, and the Agilent 1200 Infinity Series LC, which became one of the first products to earn a Silver Seal of Quality back in 2018.

Expert reviewer Tabrez Shaikh, Indoco Remedies, writes of the 1260 Infinity II LC System: “A very good LC system for HPLC, UPLC or mass interference. The system is robust and vertically slim. It is also fast and precise. Data quality is very high.”

New Seals of Quality are announced quarterly — there are currently just over 50 lab products permitted to display a SelectScience Seal of Quality.

SelectScience Editor-in-Chief and Publisher, Kerry Parker, said: “I would like to take this opportunity to thank all our reviewers around the world for sharing their valuable opinions and also to congratulate these new Seal of Quality winners, who have been recognized by the people who matter most, their customers.”

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.
