EXAPURE PA (Polyamide) Disc Filters

The EXAPURE Disc Filters PA are made of a high chemical resistant nylon (polyamide) membrane, which has been designed for applications as sensitive as the filtration of HPLC solutions.

• wide range of applications
• offer accurately controlled pore size distribution and higher strength and flexibility which ensure reproducibility and consistency
• membrane material (polyamide) is carefully selected to release the lowest extractible
• packaging: box., quantity: 100/box., colour: white, not sterile, metal-free
• exists also sterile individually packed

EXAPURE PA Syringe Filters

• designed for purification, isolation and separation
• maximised flow rate for minimised dead volume
• housing: polypropylene
• packaging: bag., quantity: 100/bag., not sterile, connection: Luer-lock / Luer-slip

EXAPURE PTFE Syringe Filters

• designed for purification, isolation and separation
• maximised flow rate for minimised dead volume
• housing: polypropylene
• packaging: bag, quantity: 100/bag., not sterile, connection: Luer-lock / Luer-slip

EXAPURE PES Syringe Filters

• for the filtration of sterile media, serums, buffers and other aqueous solutions
• a glass microfiber pre-filter ensures an economical filtration of serums while maintaining the filtration capacity of the PES membrane, which is specifically selected for its low protein binding properties
• individual packaging ensures the filter sterility until utilisation
• maximised flow rate for minimised dead volume
• housing: polypropylene
• packaging: bag, quantity: 100/bag., sterile, color: white, connection: Luer-lock / Luer-slip

EXAPURE In-Line Filters

• designed to connect directly into an HPLC line to simultaneously filter and degas the mobile phase as it is being used
• high-flow polypropylene membrane for mobile phases containing organic solvents or other highly corrosive liquids such as acids or bases.
• 1/8" MNPT filter connection is designed to match the most difficult specifications for leak-free applications, or Luer Lock
• The EXAPURE In-Line Filters PP 5-50 filter with ease highly loaded as well as viscous solutions without leaking
• housing made of a specifically selected polypropylene grade for sterile applications as well as against highly corrosive chemicals.
• the 5 µm porosity filter particularly well the coarser particles that would rapidly obstruct conventional 0.2 or 0.45 µm filters. The EXAPURE 5 µm In-Line Filters are fulfill the most demanding requirements in the chemical, but also in the food and ink industry.
• packaging: individual, quantity: 10/bag, colour: white, not sterile

EXAPURE Filters packed in roll bande

• compatible with the most dispensers
• sterile
• metal free
• 600 pieces
• gridded

Thimbles for extractors and probes (SOXHLET)

They are made of pure cellulose, neutral cotton and without fat. These thimbles are moulded in one piece. Very resistant. Used during the extraction for analysis of mud, asphalts, food products and in many devices for dust control.
