"Fill and Flip" Microplate Bead Loader

The Manual 96-well, Deep Well Microplate Loader is very simple to use.  The wells of a one ml 96-well microplate are filled to the top with beads (the 'donor' plate).  A 'receiving' one or two ml deep well microplate is positioned, up-side-down, over the filled microplate and the pair is manually inverted.  The two well microplate is now loaded with exactly one ml of beads in each well.  To facilitate this "fill and flip" method, a stainless steel frame is used to assure accurate positioning of the 'donor' microplate to the 'receiving' microplate.  Also included is a unique tray designed to catch and recover excess beads, a spatula, a 0.3 ml 'donor' microplate and a one ml 'donor' 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 are 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 or steel beads). The loader delivers a 0.4 ml load of beads to each well and is compatible with all 96-well, deep well microplates. Included is a 96-nozzle loading manifold, a hand held 110 VAC electrical suction unit and an on/off foot switch.

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 a "wall to wall" direction.  The block can be pre-cooled in a 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 a Stockwell brand 50 ml tube.  Other brands of 50 ml centrifuge tube may not fit properly.  If you need to use a different brand tube, please check with us first 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.

BioSqueezer

BioSqueezer

The BioSqueezer is used to "snap-freeze" (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 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 ground without thawing in a Cryo-Cup mortar and pestle for subsequent rapid extraction of labile nucleic acids, proteins and intracellular metabolite products.
