Ultra-pure, virgin PTFE chips promote gentle, efficient boiling and help prevent overheating, even of highly volatile liquids. Ideal for continuous extraction methods. Stones minimize "bumping" during reflux and distillation. The boiling stones are not affected by acids, hydrocarbons, ketones, esters, alcohols or alkalis. They are easily cleaned and non-contaminating. Shows no trace of face acidity or alkalinity. They will not scratch or abrade glassware and leave no residue. Usable up to 288°C.

• Chemical resistant
• Ideal for boiling organic liquids
• Minimizes superheating

• Packing for distillation columns
• Chemically inert
• High surface area per unit of volume
• Minimum resistance to gas and liquid flow

These spatulas are designed for use in the most severe laboratory conditions. They are made of nickel-plated stainless steel and fluoropolymer coating. The coating eliminates surface buildup or loss of valuable sample due to sticking. Will not scratch or damage delicate surfaces.

• Extra heavy-duty PTFE coatings
• Resistant to low and high temperatures
• Use for handling chemically active materials

DIN EN ISO 15528. For liquids. Made of ultra pure and chemically inert PTFE/FEP for contamination-free sampling. Practical push button, single-handed operation. Suitable for point, cross-sectional, and bottom sampling. Ideal for sampling from open and closed drums, kegs, tanks, silos, water sources (ponds, lakes, streams, rivers). Suitable for all commercial kegs and drums with openings of at least 32 mm diameter. All surfaces are non-porous and crevice-free preventing accumulation of dirt. Only round-profile screwthreads, suitable for food hygiene applications, are used. Simple to dismantle and clean.

PTFE balls minimize "bumping" during boiling. They are inert and can be used up to 288°C. 100 balls per package.

• For column packing and mixing beds
• Resistant to most chemicals
• Non-contaminating

Bytac^® Bench protectors, FEP Film with Vinyl or Aluminum Backing. Inert to most chemicals - Non-stick; easy to clean - Use to resurface bench tops and line fume hoods. Contrasting work surface for viewing color changes during titrations. Protects surfaces against absorption of radioactive chemicals. Vinyl backing is recommended for all applications up to 93°C. Aluminium foil-backing is resistant to high temperatures up to 182°C for up to one hour.

Capillary Pistons are designed, developed, and manufactured to fit Gilson MICROMAN® perfectly. They ensure optimal performance of your MICROMAN® pipette across the full volume range.

GLP friendly, these colored clips identify or personalize your PIPETMAN^® by snapping on to the connecting nut to help avoid mix-ups. Made of polyacetal, they can be marked with permanent ink to indicate your name or application. COLORIS™ comes in 5 bright colors: red, green, yellow, blue and white.
