微型粉碎机

Cat. No. 2941, MicroMincer laboratory press complete with 10 pack of liner/seals

Cat. No. 294103, Ten pack of extra liner/seals

 

 

The MicroMincer is a compact, hand-operated screw press which homogenizes 0.3 grams or less of fresh plant or animal tissue instantly, without sample loss, heat generation, foaming or aerosol problems. The sample, without added buffer, is pushed through a 250 micron stainless-steel sieve under thousands of pounds force. The resultant extract can be deposited directly in microtubes. The stainless steel MicroMincer utilizes disposable polypropylene liners. Thus, multiple samples can be quickly processed without cleaning or risk of contamination between samples.

 

 

 

Microanalysis of cellular constituents.

Eliminates re-concentration of sample extract.

Direct sample extraction for PAGE and agar gel analysis.

Preparation of single-cell suspensions from tissue

 

 

Place the seal on the piston/screw.

Put 100 to 500 mg of tissue into the barrel of the disposable liner. It is usually not necessary to pre-chop the tissue.

Insert the piston/screw into the barrel of the liner and slide the assembly into the press cylinder.

Screw down the press. Extract exits from the pointed end of the liner. With very small samples, the extract may remain in the liner tip but can be removed with a micropipette or small spatula.

Continue screwing down the press until all of the sample has been extracted. More pressure beyond this point will shear the plastic tip and force it out of the press cylinder. However, should this happen the liner is a disposable item and no harm is done.

Unscrew the press and remove the used liner and the used piston seal. The metal poker provided is sometimes helpful. Proceed to the next sample.

 

Directly processes very small samples without dilution with buffers or solvent.

Simple to operate, without compressed gases or high pressure electro-mechanical pumps.

No heat, foam, or aerosols formed.

The only parts in contact with the sample are the cylinder liner containing a 250 micron screen and the piston seal (all disposable).

All parts easy to clean and sanitize.

Develops thousands of pounds/square inch to mince the entire sample. No Product is lost.

Disposable parts eliminate cleanup and contamination between samples.

 

Sample is pressed at a controlled speed through a screen having 250 micron openings.

Working capacity of 100 to 500 mg fresh, frozen or rehydrated plant or animal tissue.

316 stainless steel body, piston/screw and screen.

Cylinder liner and piston seal made of polypropylene and ethylene-propylene rubber, respectively.

All parts autoclavable.

Size: 2 cm diameter, 11 cm high, weight 300g.
