Lonza 4D-Nucleofactor System

The Nucleofector technology is a major improvement of the well known electroporation technology. The (more) Nucleofector technology involves a combination of optimized electrical parameters and specific Nucleofector solutions for different cell types. This combination permits the crucials step: delivery of the DNA of interest straight into the nucleus. As the DNA quickly reaches the nucleus, expression can begin without delay. The nucleofected cells are thus ready for analysis after a short incubation time of only 2 – 8 hours. DNA quality: 1 – 5 µg plasmid concentration per nuclefection sample (100 µl), plasmid concentration can be increased up to 10 µg per sample. This may lead to higher gene transfer efficiencies, but at the same time may increase mortality of the cells. Cell density: 2 x 105 – 1 x 107 cells per nuclefection sample for suspensions cells 2 x 105 – 2 x 106 cells per sample for adherent cells Cell densities of < 2 x 105 cells per smaple are not advisable beacause the gene transfer efficiency may decrease and mortality may increase. Dimensions (WxDxH): 300 x 230 x x110 mm Weight: 2.5 kg

The BTX HT-200 plate handler allows for the Highthroughput System HT 25 or HT 96 for advanced molecu (more)lar delivery. The HT 96 (96-well) plates or the HT 25 (25-well) plates can be electroporated using a BTX generator (models: ECM 830 and ECM 630) with a plate handler. The Model HT-200 automatically switches columns in a Multi-well plate during electroporation using the Auto-track sensing featute. The Auto-track sensing allows rapid electroporation of an entire plate by setting up all columns and pressing one button. Voltage Range: 0 to 3000V DC Pulse Length Range: 10 µsec to 10 sec Pulse Number Range: 1 to 99 Dimensions (WxDxH): 230 x 215 x 140 mm Weight: 4.8 kg Including: 1x 96-Well Disposable Electroporation Plates, 4 mm, 250 µl, pkg. of 1 1x 96-Well Disposable Electroporation Plates, 2 mm, 125 µl, pkg. of 1 1x HT 25-Well Adapter for Plate Handler

This listing is for a Jenway 3540 pH & Conductivity Meter. The unit is in full working condition an (more)d is ready for immidate realese. The Jenway 3540 is a combined pH and conductivity meter designed for use in laboratories where both parameters need to be measured. It offers a space-saving and flexible approach to measuring pH and conductivity. Key Features Simultaneous display of pH and conductivity: Two independent channels prevent interference between probes. Additional modes: Resistivity, salinity, TDS, and mV measurements are available. Data logger: Autosave and print options with storage of up to 500 readings (250 for each mode). Probes sold separately: Glass combination pH electrode, glass conductivity probe (K=1), and ATC probe are available. Specifications Ranges: Conductivity (0.01µS/cm to 1.999S/cm), pH (2 to 20.000), temperature (10.0 to 105.0°C or 14 to 221°F), and salinity (0 to 99.9ppm). Input impedance: Greater than 1012 ohms. Temperature compensation: Manual or automatic, with a range of 0 to 100°C. Dimensions: 210 x 250 x 55 mm (L x W x H).

This antivibration table is intended for mass comparators. It is made of powder-coated steel and a m (more)assive granite plate placed on top. The table has a safety feature to prevent accidental slipping of the stone, as well as vibration dampening rubbers. Due to low construction, the need to lift large masses to a considerable height is reduced.
