Yeast Colony Counter

The new ProtoCOL 2 automated colony counting and zone measurement system can be used for quick and easy analysis of standard and large plates. The system offers a combination of a unique lighting method and a new total viable count (TVC) software that makes counting colonies as small as a pinprick, fast and accurate. Because the ProtoCOL 2 has an integrated processor there is no need to purchase a separate computer. The five separate ProtoCOL 2 software modules can all be integrated into a CFR 21 Part 11 environment, allowing scientists to purchase only those needed for their laboratory. The available software modules include colony counting, spiral plate counts, AMES test counts, and inhibition zone measurements. The new ProtoCOL 2 is perfect for microbiology laboratory scientists looking for a sensitive, easy-to-use, yet inexpensive colony counter or zone sizing system.

Benchtop Evaporator

The EZ-2 Elite is designed to remove high boiling point solvents and deliver enhanced solvent recovery thereby improving final drying of stubborn samples and enabling fast lyophilization of HPLC fractions. The high-performance scroll pump used with the EZ-2 Elite delivers deeper vacuum than the diaphragm pumps used on other EZ-2 systems. This advance plus internal enhancements to the heat vapor duct and system components enable the EZ-2 Elite to routinely evaporate challenging high boiling solvents including DMSO and NMP. In addition, these enhancements ensure that such challenging solvents only condense in the SpeedTrap. The EZ-2 Elite is designed to concentrate or completely dry samples. The system will accommodate a wide selection of sample holders enabling evaporation from most common sample container formats including round-bottom flasks up to 500 ml, tubes up to 160 mm long, custom reaction blocks, and shallow or deep-well microplates.

Bacterial Transformation

The new Eppendorf Eporator offers a fast, simple, and safe option to transform bacteria, yeasts, and other microorganisms with DNA/RNA. When bacteria or yeast strains are exposed to short high-voltage pulses, macromolecules such as plasmid DNA can diffuse into the cell through temporary pores in the cell membrane. The results are highly reproducible, and in comparison with chemical methods, electroporation yields up to 10 times higher transformation efficiency. Two new program buttons, designed for storage and recall of most commonly used parameters, along with the simple one-button operation, guarantee intuitive use for faster sample handling. State-of-the-art electronics and an integrated electroporation chamber offer higher safety for the user and minimize the risk of sample loss. Eppendorf offers electroporation cuvettes with three different gap widths. Due to its compact design, the Eporator can be transported easily within the lab and stored during times when it is not in use.

Automatic Fusion machine

Sample preparation by the fused bead technique is widely accepted as giving better precision and accuracy than most other techniques when analyzing minerals, ceramics, and similar samples by X-ray fluorescence (XRF). The Vulcan fusion system uses automatic fusion control to achieve better sample uniformity and repeatability. The Vulcan MA comes in several different versions. The basic XRF version has two, four, or six fusion stations, with automatically controlled flame temperatures under microprocessor control and the facility to store up to 10 different melting programs. Stable flame temperatures and simplicity of operation ensure good sample-to-sample repeatability. Controlled temperature ramping is also possible. Other configurations are designed for sample preparation for ICP or AAS, or even a mixture of XRF and ICP or AAS, and it is possible to combine the Vulcan with a dedicated fume extraction system to provide an integrated sample preparation workstation.

biochemical detector

The SpectroSens monitoring and data analysis control unit is a benchtop control center capable of monitoring up to eight independent inline SpectroSens optical sensors. SpectroSens sensors employ an innovative technology that interprets changes in refractive index to provide real-time process monitoring. The new data-monitoring unit advances the company's systems by providing a built-in, touch-screen interface while reducing the footprint by over 50 percent. Due to its new ergonomic form and smaller size, the SpectroSens unit is perfectly suited for use in a range of environments, from a small process-development laboratory up to industrial scale requirements. The multichannel capabilities of the device allow it to be connected to a number of SpectroSens sensors, whether in a single, multistage process or in situations where multiple processes are running in parallel.
