The Thermo Neslab Merlin M25 is a transportable, powerful, and extremely capable CFC- free chiller that provides users with an unchallenged level of dependability and versatility. The Thermo Neslab Merlin M25 Circulating has an extremely flexible temperature range. Because of its relatively small size and adaptable cooling range, the M25 Merlin is extremely well suited for both small and large laboratories. Along with an onboard LCD digital control and display, the M25 Merlin also features a precautionary temperature alarm to alert users whenever temperature thresholds are being reached.
The Barnstead MaxQ 2000 Orbital Shaker is ideal for shaking flasks, vials, beakers, Petri dishes, and other sample containers. Variable speed ranges and adjustable timer. Operates in temperature ranges of 0 to 40°C and humidity conditions of 20 to 80% non-condensing, enabling them to be used in incubators, warm rooms, environmental chambers and refrigerators.
Combine incubated and refrigerated temperatures with a small footprint by using Thermo Scientific MaxQ 4450 Benchtop Orbital Shakers. These versatile shakers are ideal for incubating a small number of vessels and are used for cell culture, solubility studies, extraction procedures, protein expression and many other applications.
Safely and efficiently operate Thermo Scientific Midi 40 CO2 Incubators. They use the Thermo Scientific IntrLogic II microprocessor-based control system with alphanumeric setpoint display of temperature, CO2, alarm, calibration and diagnostic functions. Enhanced microprocessor-based IntrLogic II control provides comprehensive control, monitoring and display of all incubator systems for safe, efficient operation. This is a fully featured 1.4 cu. ft. (40 L) incubator occupying less than 2 sq. ft. (0.6 m2) of space.
Operates in three modes; electric heat, steam heat, or electric and steam heat.
Ideal for the demanding requirements of daily lab applications, our range of general purpose (GP) freezers. Our line of GP Series freezers provide the reliability and security essential for the protection of sensitive lab samples in the -30°C range.
This Thermo Scientific Multi-Blok DryBath is built to provide uniform dry heating for microcentrifuge tubes, cuvettes, titer plates and various sized test tubes. The tubes are able to experience great heat transfer from the close contact to the block walls. These drybaths are used in many different areas of study including food sciences, chemistry, and clinical labs.
The Multidrop 384 Reagent Dispenser portions a wide range of solutions into 96- and 384-well plates across a 5 to 395μL volume range, providing reliable microvolume dispensing for pharmaceutical and biotechnology laboratories. It offers precise and reproducible dispensing results, high speed dispensing for high assay throughput, easy setup and easy integration with different robotic setups.
Multiskan Spectrum makes getting results easier, replacing separate spectrophotometers and microplate reading instruments by providing both functions in one convenient, compact instrument. The Multiskan Spectrum is truly two instruments in one, combining both cuvette reading capabilities and advanced microplate reading in one convenient, compact instrument. You can easily take quick absorbance measurements in a cuvette between the cycles of a microplate enzyme kinetics experiment.
For maximum flexibility, Multiskan Spectrum accepts all microplate for mats from 6- to 384-wells, as well as cuvettes from standard to ultra micro capacities in glass, plastic, or quartz. You can take multiple photometric readings per well on large format plates, or single measure ments requiring just 30 μl in 384-well plates.
Scanning range of 200 – 1000 nm. The built-in monochromator makes it simple to select any wavelength from 200 nm to 1000 nm in 1 nm steps without ever changing a filter. Sample absorbances can be scanned over the whole spectrum either in microplates or cuvettes.
Typical applications of the Multiskan Spectrum
Thermo Scientific™ NanoDrop 8000 is a muti-sample micro-volume UV-Vis spectrophotometer. With the NanoDrop 8000, you can measure more samples in less time with the same reliability and patented sample retention technology of the NanoDrop 2000.

• Necessary Cables
The NanoDrop 1000 Spectrophotometer measures 1 ul samples with high accuracy and reproducibility. The full spectrum (220nm-750nm) spectrophotometer utilizes a patented sample retention technology that employs surface tension alone to hold the sample in place. This eliminates the need for cumbersome cuvettes and other sample containment devices and allows for clean up in seconds. In addition, the NanoDrop 1000 Spectrophotometer has the capability to measure highly concentrated samples without dilution (50X higher concentration than the samples measured by a standard cuvette spectrophotometer).
UV/VIS spectrophotometry is simple for samples as small as 1 ul using the NanoDrop 1000 Spectrophotometer. The small sample requirement and ease of use make the NanoDrop 1000 Spectrophotometer ideally suited for measuring:
• Nucleic acid concentration and purity of nucleic acid samples up to 3700 ng/ul (dsDNA) without dilution
• Fluorescent dye labeling density of nucleic acid microarray samples
• Purified protein analysis (A280) up to 100 mg/ml (BSA)
• Expanded spectrum measurement and quantitation of fluorescent dye labeled proteins, conjugates, and metalloproteins
• Bradford Assay analysis of protein
• BCA Assay analysis of protein
• Lowry Assay analysis of protein
• Pierce Protein 660 nm Protein Assay
• Cell density measurements
• General UV-Vis spectrophotometry
