So. homogenizers. Quite possibly the most violent of devices used in a laboratory. When you consider that the term ‘homogenize’ is a more scientific term for ‘beaten to a (literal) pulp’. This process is used for turning organic material (such as bone, wood, plants) in to a material that can be better examined.
While we joke about homogenizers beating organic materials to a pulp, keep in mind that what a homogenizer does is actually destroy the cell walls of a material. This process is called lysis. It has many uses, far too many to go into here.
Spectrum has already carried the excellent Benchmark Scientific Homogenizers the BeadBug and the BeadBlaster. These are fine devices but they have two disadvantages: one is their lack of portability, and two is that the material needs to be inserted in microtubes prefilled with mashing material (beads). Well, Benchmark has now added a new homogenizer to their product line, it is the D1000 Handheld Homongenizer:
The D1000 is a powerful, handheld homgenizer and is one of the most powerful and affordable of its kind on the market. Coming is at $949 the D1000 includes two generator probes, most other competitive models cost the same without generators and those generators can cost as much as the original unit!
The D1000 operates using a rotor stator that draws in the material, in liquid, into the generator probe and forces it out of the side slots. The motor is powerful (130W) and has 6 different speed settings from 8,500 rpm to 30,000 rpm. The power button is separate so that speed settings can be maintained. Most materials are homogenized in about 30 seconds or less.
As we already mentioned, the D100o, like any handheld homogenizer, depends on a generator probe to operate. The D1000’s price includes both a 5mm and 7tmm wide (both are 50mm long) generator probes. These probes are excellent for use with microtubes. The 5mm is a flat bottom probe while the 7mm is a saw-tooth design.
In addition, two optional generator probes are available: a 10x 115mm probe and a 14 x 130mm probe. The former being best for 15ml and 50ml tubes, and the latter being good for 50ml tube and larger vessels up to 250ml in capacity, such as flasks and beakers.
A stand for the D1000 will also soon be available so that the unit can be set up like a homgenizing station for those who prefer to bring the sample to the homgenizer rather.
