"Fill and Flip" Microplate Bead Loader
The Fill and Flip Microplate Loader is simple to use and much faster than adding beads, one-at-a-time, to 96-well microplate wells. Handles a variety of loading needs including both spherical and irregular shaped bead media. Providing they are pourable and dry, seeds, milled agicultural products, resins and powdered solid chemicals can also be loaded.
The Microplate Bead Loader Kit consists of a bead loading platform with spatula , two different sized s.s. frames, one 0.3 ml 'measuring' microplate and one 1 ml 'measuring' microplate.
"Suction" Microplate Bead Loader
Of the three bead loaders we offer, the Suction-type 96-well, deep well Microplate Bead Loader is the fastest - Beads can be loaded into 96 deep well microplates at a rate of about 10 microplates per minute. It is limited to loading spherical glass or ceramic beads only (i.e., not irregularly shaped particles,heavier steel beads or non-beads, such as seeds and pourable chemicals). The loader delivers a 0.4 ml load of beads to each well and is compatible with all 96-well, deep well microplates.
The Suction-type Microplate Bead Loader includes a polycarbonate/polystyrene bead-loading manifold, a hand-held 115V AC vacuum unit and an on/off footswitch.

50 ml Tube Holder, Solid Aluminum
This tube holder is machined out of a 1.5 lb aluminum block and has the dimensions of a standard 2ml deep well microplate. It is used with the MiniBeadbeater-96 cell disrupter. One or two 50 ml screw cap centrifuge tubes are placed completely inside the cold block and the contents shaken in the "wall to wall" direction. The block can be pre-cooled in a deep freezer or, at cryo-temperatures, with dry-ice or liquid nitrogen.
Included with each vial block are 25 sterile, polypropylene 50 ml screw cap tubes (Stockwell brand, part # 3252).*
*Important note: To maximize the efficiency of heat transfer, this aluminum tube holder was designed to fit with close tolerance to the Stockwell-brand 50 ml tube. Other brands of 50 ml centrifuge tube may not fit properly. If you prefer to use a different brand tube, please check with us for compatibility.

BioChopper Kit
Our BioChopper Kit provides two simple tools to aid in preparing your tissue samples for homogenation.
BioCryo Tissue Grinder

Cat. No. 10810, BioMixer, 115 volt Includes three mixing attachments, grinding mill, and plastic stand.
Cat. No. 10810EUR, BioMixer, 230 volt Includes three mixing attachments, grinding mill, and plastic stand.
BioPulverizer
The BioPulverizer quickly fragments hard frozen tissue samples into tiny pieces the size of grains of sand or course powder. The primary benefit of pulverizing pieces of tissue is to optimize subsequent rapid and complete cell lysis using lytic solutions or mechanical homogenizers. For difficult tissues such as tendon, skin, and tumors it is an essential step (read more). The BioPulverizer is also used at room temperature to fragment friable, dry biomaterial such as non-oily seeds, bone and teeth.
There are four different hand-operated BioPulverizers for quickly pulverizing 10 mg to 10 g of frozen tissue.
Cat. No. 59012N, BioPulverizer, capacity 10-100mg
Cat. No. 59013N, BioPulverizer, capacity 0.1-1g

Cat. No. 792, BioRotator-6, 115 volt
Cat. No. 792EUR, BioRotator-6, 230 volt
NOTE: EACH BIOROTATOR-6 COMES WITH ONE ATTACHMENT OF YOUR CHOICE. SEE "BIOROTATOR ATTACHMENTS" BELOW TO SPECIFY.
BioSqueezer
The BioSqueezer is used to "snap-freeze" (quickly freeze) 10-100 mg of soft animal and human tissue. It does the same thing as a classic freeze clamp but is easier to use and gives more reproducable results.
Fresh tissue is compressed into a thin disc about the size of a small coin under pressure from a stainless steel clamp head that has been pre-cooled in liquid nitrogen or dry ice. Freezing occurs in a few milliseconds, thus offering a "snapshot" of metabolic events in the cells. The hard frozen disc is easily fragmented by hand or by grinding in a Cryo-Cup mortar and pestle for subsequent rapid extraction of labile nucleic acids*, proteins and other intracellular products.
* Very high molecular weight DNA is obtained by cryo-pulverizing hard frozen tissue using one of our dry-milling devices (see Cryo-Cup mortar and pestle, BioPulverizer , or MiniBeadbeater) followed by passive extraction (i.e., minimum physical stirring, pipetting or agitation during the cell lysis step in DNA extraction solution).
BioVortexer
The BioVortexer™ is a battery-powered motor drive designed to rotate stirring rods or plastic pestles in 1.5 ml microtubes. Rotating at thousands of revolutions per minute, it makes short work of dispersing centrifugal pellets or grinding small tissue samples.

DuelingSyringes™ Tissue Disperser
A low cost, disposable, tissue disperser for up to 100 mg samples of soft tissue (e.g., liver, brain and muscle). The Dueling Syringes™ tissue disperser is a significant improvement over the classic "syringe-needle-syringe" method of tissue dispersion. The needle is replaced with an embedded 500 micron stainless steel screen inside a 1 ml polycarbonate syringe. Manual passage of the sample back and forth through the screen is fast, gentle and efficient. Sold as a pack of five pairs of syringes.
Electric Juicer
Ideal for a one step preparation of cell lysate from most fruits and vegetables. Suitable tissues include tubers, squash, leafy tissues, fruits and pods. One of the few methods that do not require added liquid to obtain a cell free extract. Consequently, the highly concentrated proteins and biochemicals in the homogenate optimize down-stream purification or analysis steps. Not suitable for extracting animal tissue.
Electric Meat Grinder
This classic tool has two applications in the molecular biology area: 1) Preparing large amounts tissue (100g - >1 kg) for subsequent fast and complete cell lysis using a beadbeater, ultrasonicator, rotor-stator machine or high shear press and 2) recovering large quanties of viable single cells following incubation of the dispersed tissue with proteolytic enzymes that digest extracellular matrix.
Grinding Mill
This Grinding Mill cuts soft animal or plant tissue and some crushable 'dry' materials like some seeds and leaves. This attachment is powered by our BioMixer hand-held homogenizer.
LabTie™ "Gravity" Bead Loader
BioSpec is your source for LabTie™ Bead Loaders. The highly versitile dispenser, custom fit to your application, can quickly and accurately dispense beads, powders, seeds and irregular small partricles into a variety of industry standard plates, tubes, vials, or trays. This gravity-type loader can dispense a wide variety of sizes, shapes, densities, amounts, and volumes.

Leaf Tissue Punch
A modified paper hole punch, the leaf tissue punch produces a single 1/4 inch diameter disc. The punch holds a standard snap-top or screw-top 2 ml microvial in a fixed position while receiving the sample without further touching or manipulation.
Lever Tissue Press
The Lever Tissue Press is a top-of-the-line stainless steel garlic press improved in performance by the addition of a silicone-rubber gasket on the lever press piston.The press efficiently macerates or mechanically disaggregates 5 to 50 grams of fresh, soft plant or animal tissue. By 'soft' we mean nonfibrous tissue. Acceptible examples are muscle, brain, liver, plant fruits, some plant roots and tubers. An extra "can" is included to facilitate processing of multiple samples.
Mat Roller
1 1/2' rubber roller, for hand pressing mats onto microplates. Much easier than using your fingers but it is limited to low volume applications.
