BenchMark Scientific Part No. D1000
Homogenize most samples in under 30 sec. For volumes from 100µl to 250ml Supplied with both 5mm and 7mm generator probes Benchmark’s new handheld homogenizer, the D1000, is designed to rapidly homogenize, emulsify, suspend and disrupt biological samples. Ideal for use with microtubes, the homogenizer workds well with samples from 0.1mL to 250mL (depending upon the generator probe used). The D1000 is a rotor stator homogenizer, and works by drawing the sample, in liquid, into the generator probe with the variable speed rotor, and then forcing it out through the slots in the stator. This achieves mechanical shearing of the sample. As the sample is repeatedly drawn up and forced through the stator, additional shearing takes place. Most samples are completely homogenized in 30 seconds or less. A powerful, 130W motor drives the rotor at speeds from 8,5000 to 30,000 rpm. Speed is adjustable in six steps to meet sample processing needs. A separate on/off switch allows the homogenizer to be left at the appropriate setting. Generator probes are available in four sizes. The 5mm and7mm diameter have a 50mm length for use with samples in microtubes. The 10mm x 115mm is ideal for use with 15 and 50mL tubes and 14mm x 130mm for 50mL tubes and vessels up to 250mL. The unit is supplied with one each of the 5mm and 7mm generator probes. All the generator probes are made of stainless steel and can be sterilized by autoclaving.

Fast, efficient homogenization in about 35 seconds For all sample types, from soft tissue to bone Mix up to 24 tubes simultaneously Sealed 2.0ml tubes - eliminates cross contamination The BeadBlaster™ 24 completely lyses, grinds and homogenizes a broad variety of biological samples. Even the most difficult and resistant samples are fully homogenized, often in 35 seconds or less. The stainless steel tube carrier subjects up to 24 samples to an optimized, high speed, 3D motion, producing high energy impacts between the samples and micro-beads to release cellular contents. After homogenization, samples can be centrifuged and the supernatant collected for further processing. Operating parameters for the BeadBlaster 24 are set and displayed digitally. To protect fragile, heat sensitive samples, the unit can be programmed to operate in shortened consecutive cycles with a rest period in between. Up to 50 such programs can be stored in memory and recalled for future use. A transparent lid allows for visualization of samples, and features a mechanical lid lock that prevents opening owhen the BeadBlaster is in operation. A brushless motor reduces motor noise and provides maintenance free operation. Benchmark offers an assortment of prefilled tube kits for a variety of sample types. The popular Triple-Pure™ kits include acid washed, heat treated, zirconium beads. The beads are tested to be free of nucleases, making them ideal for molecular biology applications. A convenient starter kit (D1032-SK) is available to accommodate a broad range of sample types and optimize applications.

BenchMark Scientific Part No. Z206-A
Accepts tubes up to 50ml Compact, 11 x 14.5 inch footprint Suitable for urine and blood separations (including Platelet Poor Plasma) Optional adapter s for all common blood collection tubes The Z206-A Compact Centrifuge is suitable for a variety of applications inside both the clinical and research setting. Three angle rotor options are available permitting use with all common tube sizes from 0.2ml to 50ml. A unique 6 x 5ml swing out rotor is also available for clinical applications requiring horizontal separation within 5ml blood collection tubes. The advanced microprocessor controls feature an ergonomic turn knob that controls all settings (time, speed, accel/decel levels, etc.). The speed can be adjusted from 200 rpm up to a maximum speed of 6,000 rpm (corresponding to 4,427 x g) in the popular 50ml and 15ml rotors. The centrifuge lid features and automatic lid-lock that prevents it from being opened while the rotor is still in motion. In addition, a unique imbalance detection system is designed to automatically power down the motor in the event of improper loading of the rotor or any tube breakage. Compact, quiet, and versatile are just a few of the features found on the Z206-A centrifuge. Add to this, the proven safety features, and the result is the ideal centrifuge for a variety of clinical and molecular biology applications.

Eliminates weighing Fast dissolving, just two minutes Environmentally friendly, free from organic solvents Consistent, reproducible gels Enhanced resolution and clarity Researchers trust Agarose LE to meet their electrophoretic needs for a variety of applications. Now the same agarose is available in a convenient, no mess tablet. Agarose LE is refined in an advanced process that excludes the use of organic solvents. The result is a cleaner end product with significantly reduced environmental impact. The agarose can be used for analyses of nucleic acids from 150bp to 6kbp, protein electrophoresis and various blotting protocols. The low EEO of the agarose promotes increased electrophoretic mobility, yielding improved resolution and shorter run times. This also allows macromolecules and larger particles (subcellular fragments, viruses, etc.) to migrate more freely through the gel matrix. The consistently low EEO reduces band distortion (caused by counterflow) that can result from the presence of excessive sulfate-rich negative ions. The quick dissolving EZ Pack tablet contains 0.5g (500mg) of Agarose LE, eliminating the hands-on time and inaccuracies normally associated with weighing. Use of the tablet is not only convenient and cleaner, it also provides better consistency and reproducbilty gel to gel. Gel preparation is simple - add the desired number of tablets to electrophoresis buffer, alow to sit for two minutes and then heat and pour as usual. The resulting gels are highly transparent, have exceptional thermal stability (ensuring safe and easy handling) and exhibit exceptionally low absorption of chemical staining agents. EZ Pack Agarose Tablets are supplied in convenient blister packs for safe, clean dispensing.
