Branson 2510R-DTH Ultrasonic Cleaner

Branson 2510R-DTH Ultrasonic Cleaner

Cambridge ID #: 20417

Designed for performance, control, durability, and reliability for a variety of applications. The Branson 2510R-DTH is powerful enough to remove heavy oils, buffing compounds, and proteins, consistent enough to manage difficult laboratory cleaning, while also safe enough for delicate components or fine jewelry. Ultrasonic sound waves move through a cleaning solution, creating an effect called cavitation, which is the rapid formation and collapse of microscopic bubbles. The 40kHz transducers provide increased cleaning power with built-in sweep frequency for uniform cleaning throughout the bath.

Specifications:

 

  • Tank Capacity: 2.81 L
  • Temperature Range: Ambient to 69°C
  • Temperature Readout Accuracy: ± 4°C
  • Dimensions: 13.5” x 12” x 11.5” in (L x W x D)

VWR 9005 Environmental Chamber Incubator

Cambridge ID #: 15538

These accurate and reliable chambers are ideal for long-term high temperature and relative humidity (RH) testing. Designed to provide a wide range of environments, these units are suitable for both industrial and biotechnology specification testing, specifically continuous-duty projects.  All models are equipped with a gentle horizontal air flow system, which ensures stable, top-to-bottom temperature and RH uniformity. Low temperature models 9005L and 9010L feature CFC-free refrigerant. Relative humidity range may vary depending on temperature set point.  Digitally set, microprocessor temperature and humidity controllers allow precise setting with direct digital read-out in degrees and percentage RH.  The over-temperature safety control prevents possible damage to samples or equipment. A vapor generator compresses moisture and injects it into the chamber to provide controlled humidification. Automatic water level control maintains liquid level in humidity reservoir. Pressure coupling allows for easy hook-up of in-line plumbing or a carboy of distilled water. All units feature interior drain.

Specifications:

  • Temp range: 40 to 70°C
  • Capacity: 9 cu ft.

Persee A3AFG *NEW* Atomic Absorption Spectrophotometer

Persee A3AFG *NEW* Atomic Absorption Spectrophotometer

Cambridge ID #: 21357

Features:

The A3 Atomic Absorption Spectrometer is a high performance automated instrument designed to meet the requirements of the modern laboratory. Due to its versatility and performance it can be used for a wide range of applications. 

Three flame options are available to the user with the Air/Acetylene being the standard configuration. This flame can be used for nearly all standard elements while the N2O/Acetylene and the Air/LPG (natural gas) are available as an option for the more demanding of elements. All three flame configurations offer coded burner for full safety protection. 

The graphite head is fixed into the optical path to maximize performance and eliminate drift. The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system. Pyrolytically coated platform tubes are supplied as standard to improve the performance and eliminate many analytical problems associated with this technique. 

The flame and graphite furnace can be changed over by a simple selection in versatile AA Win Pro software.
