Visual chemical tests

Manufactured from high quality PTFE with excellent resistance to all chemicals. Manufactured from molded, pure PTFE with a smooth internal finish. Flat base enables a flat contact to the surface for effective heat transfer. PTFE beakers have excellent resistance to chemicals and temperature stability from -200°C to +260°C.

PFA jars store solutions, paste and bulk materials with no concern about leaching, corrosion, contamination or evaporation. They are resistant to corrosive liquids, acids, solvents, sensitive reagents, and staining solutions. PFA jars feature a large mouth for easy access and non-stick surface for easy cleaning. There is an area for identification marking on the side of the jars. Stackable, these jars have a knurled top for secure grip to facilitate easy opening and closing.

• Chemically resistant
• Ultra-pure
• Heat resistant and usable to cryogenic temperatures
• Secondary inner seal design for safety and integrity
• Ideal for storing digestion samples

Griffin Beakers, PTFE are non-contaminating and completely inert to highly corrosive reagents. They are non-wettable, unbreakable, lightweight, and heat resistant. Easy to clean, these beakers have a broad spout for easy pouring. They can be heated on a hot plate up to 288°C when proper care is exercised. The specially molded bottom allows rapid heat transfer.

• Can be heated to 550°F (288°C) and used in a microwave
• Chemically resistant to acids and bases
• Ultra-pure

Transparent. Teflon^® FEP bottle with leakproof Teflon^® ETFE screw cap. Highly resistant to chemicals, corrosion and temperature. Autoclavable - cap should be unscrewed and sat loosely on neck before autoclaving.

Highly transparent. Class A tolerances according to DIN EN ISO 1042.
The PFA screw cap guards against contamination.
Outstanding chemical resistance, can be used with strong oxidants, highly concentrated acids and alkalis, hydrocarbons, and ketones.
With laser-engraved lot number and batch certificate. Thermal stress up to 121ºC (autoclaving) does not permanently exceed the tolerance limit.
To preserve the ring mark, do not clean at temperatures exceeding 60ºC.

The advantages of PFA

• Long-term maintenance of low-concentration reference materials in PFA containers
• No memory effects
• Practically no carryover, no cross-contamination due to the extremely hydrophobic, anti-adhesive and smooth surfaces
• High thermal stability, from -200°C to +260°C
• Chemical inertness against nearly all chemicals
• Good transparency and dimensional stability, suitable for volumetric instruments
• Easy to clean
• Use of high purity raw materials

Screw cap, jet and feed tube are one-piece moulded from ETFE. Ideal for contamination-free work and suitable for trace element analysis.

Griffin Beakers, PFA have a specially machined bottom designed for rapid, efficient heat transfer. They are transparent for easy viewing and graduated for easy measuring. They feature a non-stick, easy-to-clean surface.

• Can be heated up to 260°C and used in a microwave
• Ideal for ultra-pure applications
• Low metal ion content for trace metal analysis

These graduated cylinders offer all the advantages of non-stick inert fluoropolymers. PFA is temperature resistant from -196°C to 260°C and has the lowest metal ion content. As a result, Chemware^® cylinders are excellent for trace metal analysis.

• Easy-to-read graduations
• Smooth pouring, drip-free spout
• Broad base for stability

• Chemical and corrosion resistant
• Temperature resistant from -270 to +250 ° C
• Leak-proof Teflon ™ PFA screw caps
• Autoclavable

These wash bottles feature a wide-mouth opening for convenience in filling and pouring of all types of liquids. Non-stick and easy to clean, fluoropolymer construction provides superior flex life and mechanical strength. As PFA contains the lowest concentration of trace metal ions of all fluoropolymers, these bottles are ideal for ultra-pure applications and environmental work.

• Wide-mouth for easy filling
• Chemically inert and leak-proof
• Flexible nozzle with 360° swivel; small orifice allows accurate content dispensing
• Transparent and break resistant
• Molded-in graduation marks
