Bottles are manufactured from Type I borosilicate glass.
Ideal for incubating diluted samples of sewage, sewage effluents, polluted waters, and industrial wastes to determine biological oxygen demand.
Specially designed shoulder radius sweeps all air from inside the bottle during filling.
Interchangeable stoppers have a tapered bottom that also prevents air entrapment.
Numbered versions supplied with bar codes for quick and accurate recording of bottle numbers.

BOD bottle used hold a water sample for testing and analyzing dissolved oxygen, organic material, and aerobic biological organisms.
Borosilicate glass body for chemical, thermal expansion, shock, and heat resistance.
Boston round shape for applications that require a rounded body, short neck, and narrow mouth to store liquid samples and solutions, and dry materials.
Pennyhead glass stopper with a tapered bottom that helps prevent air entrapment.
Unnumbered marking area to label for security and accountability.

FEATURE - Syringe filter nylon membrane diameter 13mm, pore size 0.22um, 100pcs.
HYDROPHILIC MEMBRANE - Nylon is hydrophilic membrane and an extremely clean and strong membrane with very low extractable levels. It is a good 'workhorse' membrane choice where acidic samples are not involved..
HIGH THROUGHPUTS - The Uniform aperture structure of filter nylon membrane offers a high dirty loading capacity, higher through-puts and higher flow rates..
NO LEAK- We use premium virgin polypropylene housing and welded with a high-quality membrane, so you can be sure your filter will never leak sample solvent..
AAPPLICATIONS - Tissue culture media preparation, filtration and clarification of biological fluids,Probe solutions,Protein and enzyme filtrations,Hybridization buffers..

【High Efficiency】COBETTER Ultrafiltration Centrifuge Tube can reach the concentration multiple of 80-100 times, and the general concentration time is 10-60min..
【High Efficiency】The RC membrane and smooth inner wall design have extremely low protein adsorption and can achieve a recovery rate of more than 90%..
【Wide applicability 】Both fixed angle rotors and swing bucket rotors are applicable..
