Product Description

The DeNovix DS-11+ spectrophotometer uses standard quartz or disposable cuvettes for up to 10 mm pathlength absorbance measurements (190-840 nm). Cuvette applications include nucleic acids, proteins, colorimetric assays, OD600 and custom standard curves. Systems include a cuvette block heater for Kinetics studies from 37-45°C.

Manufacturers Trust D.A.I. Scientific

D.A.I. is proud to represent an innovative and award-winning company like DeNovix.

DeNovix was formed in 2012 by a group of scientists and engineers with proven track records of manufacturing innovative products. They are driven by their passion to support and facilitate the advances made in today's scientific community.

The award-winning instruments by DeNovix are powered by their EasyApps® software. Pre-configured apps ensure that workflows are optimized and simple to use.

Each DeNovix instrument has the ability for onboard data storage. If you have to export your data, you can email, download to a USB or even print.

Product Features

SmartPath® Technology
The proprietary algorithms provide ultra-precise results by using real-time absorbance feed assessments to determine the optimum pathlength with which to measure the sample. This enables a best-in-class lower detection limit (0.75 ng/uL dsDNA, 0.60 ng/uL RNA or 0.04 mg/mL BSA) and the highest max detection (37500 ng/uL of dsDNA or 1125 mg/ml of BSA protein).
EasyApps® Software
DeNovix Spectrophotometers and Fluorometers are compact, stand-alone instruments with intuitive, EasyApps® for quantifying DNA, RNA and Protein. Pre-configured apps ensure that workflows are optimized while simple-to-use Custom Method apps enable researchers to quickly create and save methods. EasyApps® software also provides a multitude of choices for reviewing and exporting results. DeNovix SmartQC™ software alerts the user and advises on potential issues.
Always Calibrated
The DS-11 Series uses a high precision screw and optically encoded motor combination to make precise and reproducible pathlength adjustments. The system does not require regular calibration checks. There is no downtime or expense required for routine calibration like many other spectrophotometers.
Best in Class 1 uL Sensitivity and Highest Absorbance Capability
DS-11 Series Spectrophotometers set the industry standard for the lower detection limits of 0.5 -1.0 uL UV-Vis sample analysis. Detect to 0.75 ng/uL dsDNA, 0.60 ng/uL RNA or 0.04 mg/mL BSA. The DS-11 can measure samples with absorbance values as high as 750 absorbance units (at a 1 cm equivalent path length). This translates into 1125 mg/ml of BSA protein or 37500 ng/uL of dsDNA

Why D.A.I. Scientific

  • Does It Matter Where You Buy Your Lab Equipment?
    Not all lab equipment suppliers are created equal. Here is why you should get a quote from D.A.I. Scientific:
  • Competitive Prices
    Since we directly represent the manufacturer, you get the best price available — unlike a distributor who buys the product and then marks up the price to you. We have long term relationships with these manufacturers that provide not only a great price but superior equipment packages.
  • Providing the Right Recommendations
    We work with a lot of lab equipment consultants and architecture and engineering firms to provide recommendations for new buildings or renovations. But we’re your resource no matter what. Companies continually call us for ideas and recommendations on equipment purchases even after a project is finished, and we’re happy to help.
  • 50+ Years of Experience
    We’ve sold thousands of pieces of lab equipment, which means we know how to avoid common challenges and pitfalls that can occur during a purchase. If you need help with purchasing a single piece of equipment, or an entire lab for a new building, let our experience save you time, money and unnecessary headaches.
  • No Surprise Fees
    We believe in complete transparency, which means we won’t surprise you with any fees during the process. We’re up front about our pricing, and our goal is to help you understand the complete cost from order and delivery to setup and training.
  • Training
    Our experienced, factory-trained representatives have the specialized knowledge to answer your questions and help you pick out exactly what you need. They can also help you set up your equipment, provide training for you and your lab technicians and answer questions over the lifespan of your product.
  • One-Source Provider
    We have a long history of working with market-leading manufacturers, and customer service is our top priority. Whether you need a single replacement unit for your lab or an entire equipment package, D.A.I. Scientific is your one-source provider for all your laboratory equipment needs.
