50 ml Tube Holder, Solid Aluminum

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.

BioPulverizer

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

BioSqueezer

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 grounding in a Cryo-Cup mortar and pestle for subsequent rapid extraction of labile nucleic acids, proteins and other intracellular products.

CryogenicTissueGrinder

CryogenicTissueGrinder

The CryogenicTissueGrinder is a high-speed blade mill that grinds 1-10 grams of microbial, plant, animal and human tissue having high water content (~70%) to a fine powder in the presence of excess dry-ice. At solid CO2 temperatures, the hard and brittle sample is powdered in seconds.  Pulverizing tissue at very low temperature stabilizes intercellular biochemicals and prepares the tissue for rapid extraction in an appropriate liquid media.

Electric Juicer

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.
