Description
A rapid and effective way to:
- Homogenize cells and tissues
- Release intact organelles
- Prepare cell membranes
- Release labile biochemicals
- Produce uniform and repeatable homogenates without subjecting the sample to extreme chemical or physical stress.
Parr Cell Disruption Vessels
Parr stainless steel vessels for processing cell suspensions by the nitrogen decompression method are made in several sizes with full opening heads and self-sealing closures which can be handled easily on any laboratory bench without special tools or fixtures. Each vessel has two valves and a pressure gage: one valve for charging with nitrogen and the other for withdrawing the homogenate and discharging it through an attached delivery tube. All of the fittings as well as the vessel itself are made of stainless steel with polished surfaces for good corrosion resistance and freedom from contamination. The individual parts are easily cleaned and can be thoroughly sterilized.
The 4635, 920 mL, vessel is the general purpose model with a capacity for treating samples ranging in size from a few milliliters up to 600 mL.
The 4639, 45 mL, vessel is designed specifically for small samples from 30 mL down to less than one milliliter. It has a tapered bottom that drains directly into the discharge valve, ensuring complete recovery of all of the sample.
The larger vessels, 4636 (1850 mL), 4637 (1 gallon) and 4638 (2 gallon), are intended for large volume applications. Users are urged to run preliminary experiments in the 4635 Vessel to confirm the suitability of the procedure before scaling up to these larger sizes.
