Pall® 25 mm, In-line Filter Holders

• These 25 mm in-line filter holders are ideal for liquid or gas filtration.
• Ideal for liquid or gas filtration
• Lightweight
• For low pressure applications

The filter holder in Delrin plastic offers broad chemical compatibility and material strength. Likewise the stainless steel filter holder features durable construction with excellent chemical resistance and can withstand high operating temperatures and pressures.

These are lightweight and useful for low pressure applications such as in-line air cleaning, liquid filtering, or particulate sampling.

15mL and 50 mL screw cap centrifuge tubes that are now available in individual sterile packets. Individual packets eliminate the worry of whether or not tubes in an already opened bag are still sterile and creates an ease of not having to fumble around with open bags or racks of 50 tubes. These are sterile right up until the time you open the convenient easy peel package.

The conical 15ml and 50ml centrifuge tubes are made of premium polypropylene for clarity and centrifugal strength. Tubes and caps may be frozen at temperatures as low as -86°C. The maximum centrifugal force is 12,000xg for the 15ml tubes and 15,000xg for the 50 ml tubes*. Caps have a flat top surface for easy marking and labeling.

• Sterile, individually wrapped
• RNase, DNase, and Pyrogen free
• Easy peel wrappers
• Flat, markable screw caps

Pall® Polysulfone Filter Funnel

The 25 mm filter funnels are ideal for liquid clarification, vacuum filtration, scintillation counting studies, particle contamination analysis, etc.

Material options available

• The polysulfone filter funnels are less expensive than stainless steel filter funnels and more durable than glass hardware
• The stainless steel filter funnels are corrosion-resitant and offer excellent chemical compatibility.

Tacky Mat entrance mats are made from an incinerable polyethylene film that removes particulates before entering the clean room area. Seamless, one-piece construction allows full surface coverage and eliminates gaps between mats for large surfaces. Numbered tabs provide easy identification and sheet separation. Mats allow easy movability for carts and wheeled machinery as well as removal of wheel borne contaminants. Contains a special anti-microbial agent to provide long-lasting protection against bacterial growth.

SuperClear® Screw Cap Microcentrifuge Tubes

Pall® Biodyne® Nylon Transfer Membranes

• High sensitivity and low background for enhanced detection and resolution.
• Will not crack, shrink, or tear when subjected to multiple cycles of hybridization, stripping, and reprobing
• Membranes are intrinsically hydrophilic for easy wetting
• Offers superior performance with radioactive (Biodyne B membrane) and non-radioactive (Biodyne A membrane) detection systems

Four Chemistries Provide Versatile Adsorption Properties:

• Biodyne A Membrane - (Amphoteric Nylon 6,6) Membrane zeta potential can be modulated by changes in pH. Ideal for single probe or multiple rehybridizations, and applications where background is troublesome.
• Biodyne B Membrane - (Positively-charged Nylon 6,6) Pore surfaces are populated by a high density of quaternary ammonium groups. Our highest sensitivity nylon membrane for nucleic acid applications.
• Biodyne C Membrane - (Negatively-charged Nylon 6,6) Can be derivatized by coupling reactions through the carboxyl groups on the pore surfaces.
• Biodyne Plus Membrane - (Positively-charged Nylon 6,6 with an extremely high isoelectric point) With certain nonradioactive detection systems, it is more sensitive than Biodyne A membrane while exhibiting lower background than Biodyne B membrane.
