Tisch Scientific PTFE Syringe Filters, 0.45 µm, 13 mm, 100/Pk - SF14467

Tisch Scientific's sales team brings fast, courteous service to every filtration order, from first quote through fulfillment. Because each syringe filter is dedicated to one sample, a failed or contaminated filtration stays isolated to its own analyst's run and leaves the next analyst's queue clear. The hydrophobic PTFE membrane suits gas, vent, and solvent-stream filtration and filters aggressive organic solvents without breakdown. The PP housing stays inert across common laboratory solvents and buffers in routine use while holding its seal true run after run and maintains a low-dead-volume internal flow path. Where small-volume samples must reach the instrument clean, low hold-up volume keeps sample loss minimal while the instrument stays protected from particulate damage.

Membrane Characteristics

• Membrane integrity holds across repeated autoclave sterilization cycles at 121°C to 134°C
• Chemical resistance spans the full pH 1 to 14 range
• Strong oxidizing agents like nascent chlorine and concentrated sodium hydroxide cause no attack
• Inert composition offers no nutrient source for microbial growth
• Gas-venting and liquid-blocking function survives repeated autoclave sterilization cycles

Housing Characteristics

• Polypropylene housing withstands rated backpressure from dense sample matrices without deformation
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Resists stress cracking from aqueous salt and buffer solutions

Particulates left in your organic solvents and reagents carry downstream into the step that depends on a clean feed. Reliable solvent prefiltration keeps a stray particulate from carrying into your downstream work before it carries into further processing. Standardize your filtration purchases across every method with volume pricing and documentation from the Tisch Scientific team.
