The MicroMincer is a compact, hand-operated screw press which macerates 0.3 grams or less of soft fresh plant or animal tissue (e.g. muscle, liver, brain, epicotyl and pulpy leaf tissue) without sample loss, heat generation, foaming or aerosol problems. Much of the sample, without added buffer, is…

The Mini-Beadbeater-96 is high-energy, high-throughput cell disrupter. In a single 1-3 minute batch run it handles up to 192 samples using a deep-well microplate format or 45 samples in 1.5 or 2 ml screw-cap microvials. In a busy day thousands of samples can be processed. The MiniBeadbeater-96…

Stainless steel beads have a density of 7.9g/cc. They are used mostly for grinding leaves and seeds. They are made of Type 316 stainless steel - the most corrosion resistant available.

The Cryo-Cup Grinder consists of a stainless steel, semicircular bowl (or mortar) imbedded in a double walled, insulating cup. Up to 5 grams of hard frozen tissue is placed in the mortar precooled to liq N2 temperature. Using the special hand-held pestle made of non-heat conducting plastic, the…

A compact, low cost screw-press designed to pulverize 50-500mg of hard, brittle material such as bone or teeth. If fresh tissue is used, the sample is cooled in liquid nitrogen to make the tissue hard and brittle, inserted into in the pre-cooled pulverizer 'nut' and then crushed by manually…

Preliminary information suggests that plant and animal tissue can be disrupted more quickly with sharp-edged material rather than smooth beads. Particles are sold in one pound bottles. The sharp, hard edges of these irregular particles impart a knife-like cutting action during high-energy…

The Mini-Beadbeater-16 is a high-energy cell disrupter designed to handle four to sixteen samples at a time. The Mini-BeadBeater-16 disrupts microbial cells and plant and animal tissue by violently agitating four to sixteen 2 ml screw-cap microvials containing small glass, ceramic or steel beads…

The BeadBeater disrupts microorganisms, single-cell preparations and pulverized plant and animal tissue with better than 95 percent efficiency. Up to 80 grams (wet weight) of cells can be processed in a typical three minute run. Relying on a unique crushing or cracking action rather than high shear…

The BioMixer is a versatile high-speed blender/mixer. Designed for one-hand operation, the BioMixer can be used with any suitable beaker or vessel having at least a 2 inch opening. Three stainless steel attachments allow any combination of mixing, emulsifying, shredding or chopping. A grinding mill…

Tungsten Carbide has a density of 14.9g/cc. While very dense, this bead is not recommended for biopreps. It will leave your prep dirty. Note: These beads impart a brown-gray color to homogenates. This inert, colloidal tungsten-carbide can often be removed by centrifugation or filtration.

The BioPulverizer reduces tissue hard-frozen in liquid nitrogen to a fine powder. Because of the high water content, most fresh tissue becomes as brittle as glass at liquid nitrogen temperatures. A sharp blow with a hammer will shatter it into tiny pieces. Called freeze-fracturing or…

The Mini-BeadBeater-24 disrupts microbial cells and plant and animal tissue by violently agitating four to twenty-four 2 ml screw-cap microvials containing small glass, ceramic or steel beads and 0.1 to 1 ml disruption buffer. Even resistant samples like yeast, spores or fibrous tissue are…

The BioHomogenizer is a rotor-stator type tissue homogenizer designed to rapidly homogenize, disperse, and emulsify biological samples in aqueous media from 1 to 1000 ml. The BioHomogenizer includes both the motor and probe. The powerful 10,000 rpm motor is totally sealed and can be hand-held or…

The solid aluminum vial rack holds forty-eight 2ml vials. It is an important accessory for the MiniBeadbeater-96 bead mill. When temperature control of samples is a concern, the aluminum vial rack will keep the sample temperature at the desired temperature during the beadbeating process.

The BioRotator-6 is a compact, rotational mixer used for a wide variety of mixing needs. The mixing angle is fully adjustable and six mixing speeds are provided. When adjusted with the rotation axis of the motor in a horizontal position, a roller tube attachment (792E) permits hybridization and…

Small sample laboratory mixer and homogenizer Stainless steel rotor-stator Handy and mobile High speed, powerful 5,000 to 30,000 rpm motor with speed control Achieve any combination of mixing, emulsification, shredding or chopping. Homogenization in less than 1/2 mL treatable…

Small volume blender chambers with stainless steel blades suitable for smaller volumes.

The leaf tissue punch produces a single 1/4 inch dia. disc. The punch holds a standard snap-top or screw-top microvial in a position to receive the sample without further manipulation.

Zirconia/Silica has a density of 3.7g/cc (50% more dense than glass - good for spores and most tissues). Beads are sold in one pound bottles.

Chrome steel has a density of 7.9g/cc (used mostly for grinding leaves). Beads are sold in one pound bottles.

Thick-walled aluminum chamber with Teflon rotor. Working volume is 15 ml. The chamber can be precooled and the superior heat capacity and large mass of the 1/2 inch thick aluminum walls will keep the sample cold. The SASC-15 can also be combined with the BeadBeater ice water jacket (the later comes…

Tissue grinders are designed to gently homogenize fresh, soft tissue in an excess of an appropriate solvent. Most tissue grinders are made of glass or plastic. This all stainless-steel mortar and pestle (Potter-Elvehjem style) tissue grinder provides superior temperature control and greater plunger…

The BioSqueezer is used to quickly freeze 10-100 mg of soft animal and human tissue. Fresh tissue is compressed into a thin disc about the size of a small coin under the pressure of a stainless steel clamp head that has been pre-cooled in liquid nitrogen or dry ice. Freezing occurs in a few…

Garnet sharp particles are sold in one pound bottles. Average size +/- 20% Like Silicon Carbide sharp particles, these abrasive particles have sharp cutting edges that may accelerate lysis of plant and tough animal tissue in a Mini-Beadbeater vial. Unlike Silicon Carbide particles, Garnet…
