Unlock Rapid, Precise Analysis with the MacroRAM Raman Spectrometer
The MacroRAM Raman Spectrometer is engineered to deliver fast, reliable results across a wide range of applications. Whether you're in a fast-paced industrial setting or a dynamic academic lab, the MacroRAM streamlines your workflow, saving you valuable time and resources.
Key Benefits:
- Quick, Easy, and Efficient Raman Spectroscopy
- Raman spectroscopy requires little to no sample preparation, saving you time, money, and consumables, resulting in a low cost of ownership.
- The simple and easy installation of the MacroRAM and the short warm-up time of less than one minute means you can start measuring samples immediately, eliminating delays and maximizing productivity.
- Superior Sensitivity and Wide Dynamic Range
- The high quantum efficiency of the BI-NIR CCD (~4x more QE in the NIR than a standard OE CCD) allows for measurement of the C-H, N-H, and O-H stretching regions, providing more information about the sample than other macroscopic Raman systems on the market. This CCD combined with the high-powered 785 nm laser delivers exceptional sensitivity, allowing for the measurement of low concentration samples.
- On the other hand, the wide dynamic range of the CCD (55,500:1), combined with the fully adjustable laser power, allows for the measurement of samples of varying concentrations—all on a single system!
- Safety in Any Environment
- Safety is paramount in any environment, whether in academia or industry. The MacroRAM offers Class 1 laser safety when using the fully enclosed internal compartment. A lid safety interlock ensures that the laser does not turn on until the lid is completely closed, and turns off immediately once the lid is opened, minimizing any potential safety risks.
- When using an external fiber coupled probe, multiple external safety interlocks and an internal shutter provide an extra layer of protection, which is particularly important when multiple users operate the system.
- Robustness and Versatility
- The compact and robust design of the MacroRAM makes it ideal for both laboratory and field applications, expanding its versatility for various applications.
- The MacroRAM enables incredibly fast measurements—fractions of seconds—allowing you to track rapidly changing processes in real-time, at-line, in-line, and/or in-process. This is crucial for applications like monitoring polymerization reactions or other dynamic chemical processes.
- Effortless Operation and Powerful Analysis
- Our user-friendly LabSpec software simplifies operation, allowing you to obtain spectra with a single press of a button.
- For advanced data processing and analysis, LabSpec software offers a complete solution to extract the precise information you need from your samples—quickly and effortlessly. And, with seamless integration of spectral database searching software, you can identify materials instantly, all with a single click!
- The LabSpec software also enables 21 CFR Part 11 compliance to meet FDA guidelines for pharmaceutical applications.
- Flexible sampling options
- The MacroRAM offers a wide array of sample holders (cuvette holder, powder/solid holder, external probes, flow cell, temperature drawer, etc.), providing the flexibility to measure all types of samples quickly and easily.
- The ability to connect external probes extends this versatility, enabling measurements of liquids, larger samples, and other challenging materials through immersion or stand-off techniques.
- Ideal for Teaching Laboratories
- In any teaching environment, safety is of utmost importance. The MacroRAM has Class 1 laser safety when measuring in the fully enclosed internal compartment, ensuring the laser cannot be turned on unexpectedly, and minimizing any potential safety risks.
- To facilitate the use of the MacroRAM in an undergraduate teaching laboratory setting, a series of educational labs are available. To learn more about these labs, please visit MacroRAM Educational Labs

Accessories
HPLC Flow Cell
With a sample capacity of 20 μL, this non-fluorescing fused silica cell is ideal for on-line monitoring of Raman samples. The cell maintains high sensitivity because it has a large aperture for collecting the excitation light to the sample and spontaneous Raman emission from the sample. The flat sides allow maximum throughput while keeping the scattering of the incident radiation to a minimum. In order to use this cell, the user must also have the thermostatted cuvette holder.
Standard Quartz Cuvette
With a 4-mL volume, this cell measures 10 mm × 10 mm in cross-section, and comes with a Teflon® stopper to contain volatile liquids.
Reduced Volume Cuvette and Adapter
Reduced volume cuvettes are available in 250 µL or 500 µL volumes. Each reduced volume cuvette requires an adapter to fit properly into the standard cuvette holder.
Fused Silica Cuvette
This 2-mL to 4-mL non-fluorescing fused silica cell can accept a magnetic stirrer, has a 10-mm path length, and includes a white Teflon® cap that prevents sample evaporation.
Thermostatted Cuvette Holder
The Thermostatted Cuvette Holder keeps a sample at a constant temperature from -20°C to +80°C. From 5°C to +80°C the temperature is maintained with just water. Below 5°C the temperature is maintained by an ethylene glycol/water mixture pumped through an external circulating temperature bath (not included). The holder also includes a magnetic stirrer, enabling mixing of turbid or viscous samples. For temperature measurements, the user must supply their own or purchase the Temperature Bath.
Solid Sample Holder
The Solid Sample Holder is designed for samples such as thin films, powders, pellets, microscope slides, and fibers. The holder consists of a base with a dial indicating angle of rotation, upon which a bracket, a spring clip, and a sample block rest. This holder comes standard with every MacroRAM.
Cuvette Holder
The Cuvette Holder is designed to hold standard 10 mm x 10 mm cuvettes for measurements of liquids. With additional adapters, reduced volume cuvettes or smaller cuvettes can also be placed in the Cuvette Holder. This holder comes standard with every MacroRAM.
SuperHead
The SuperHead is a high efficiency remote Raman probe which enables in situ non-invasive chemical analysis to be undertaken. The purpose of the SuperHead is to efficiently deliver the laser beam to the sample material, and to collect and filter the returning Raman signal.
The SuperHead uses a single FC/PC terminated fiber for delivering the laser excitation and another FC/PC terminated fiber for signal collection. High efficiency filters incorporated within the probe provide effective laser and Raman filtering.
The SuperHead can perform measurements in a non-contact/non-invasive mode or in an immersion mode, using specific accessories.
Temperature Bath
For studies of samples whose properties are temperature-dependent, use theTemperature Bath along with the Thermostatted Cuvette Holder (see above). The controller circulates fluids externally, with tubes leading to the sample chamber. The temperature range is from –20°C to +80°C. Sensor and all cables are included with the Temperature Bath and it is available in a 110V and 220V version.
External Probes
Various external immersion and touch probes are available to add to the MacroRAM. External probes can be easily connected to the MacroRAM for measurements outside of the sample compartment to accommodate larger or irregularly shaped samples.
