Sterilized so they won’t contaminate your samples or lines, these liquid samplers are often used in food processing, pharmaceutical, and biotech applications. Unlike traditional sampling methods such as ladles and cups, they don’t expose samples to the surrounding environment. These samplers use gravity to draw out liquid through the needle directly into the bottle or bag. The needle has a luer lock connection, so it’s easy to remove the needle after you take the sample. You can also swap the needle out beforehand if your application needs a different kind.

Manufactured free of contaminants and allergens, all are BPA- and latex-free. They’re also TSE/BSE compliant, so they’ve never come into contact with any animal products.

Bottles have a leakproof lid, so they’re good for shipping and storing small samples. After you collect the sample and remove the needle, their membrane automatically seals. They come with a tamper seal label to put over the lid, showing if the bottle is ever opened. They're also phthalate-free.

Bags are best for taking large samples. All are ISO 10993 compliant, so they’re approved for use in medical devices. They meet USP Class VI, meaning they’re made of plastic that’s been tested to the highest standards to reduce the risk of leaching into biological samples.

All of these liquid samplers are typically used with sampling tube fittings.

Pump the handle to draw liquid out of a tank or drum through a hose into sample bottles. Only the hose and hose weight come into contact with the liquid, reducing the possibility of cross contamination.

Collect and measure buildup from the bottom of oil tanks, septic tanks, wastewater lagoons, and other areas. Unlike other samplers that only hold liquids, these samplers can draw in solids, too. They help you monitor sludge, which is important for maintaining healthy heating systems and meeting environmental regulations for sewage. Not for use with ethanol or ethanol-blended fuel.

Made of a strong plastic, these samplers are rigid enough to push through tough layers of sludge to collect a complete sample. A valve lets in liquids and solids, then blocks them from going out. Samplers are clear and marked with 1-ft. graduations, so you can view and measure what’s inside. Press down on the valve pin to empty.

These samplers consist of three hollow 5-ft. tubes. Screw together as many as you need to match the depth of your tank. Since they’re detachable, they’re easy to transport. Add extensions (sold separately) to make samplers longer.

Measure ingredients for your food processing line. To help you comply with Hazard Analysis and Critical Control Point (HACCP) programs, these spoons contain metal and chemical additives that make them set off metal detectors and show up on X-ray machines. They’re also bright blue, so workers can easily spot broken pieces that fall into your line. Made of polypropylene, they’re lighter than metal spoons and won’t scratch surfaces. These spoons are FDA compliant for direct contact with food.

Take liquid samples in sanitary environments—these sampling valves have a hygienic design, so they’re commonly used in breweries and wineries. With a body made of 316 stainless steel and a PTFE plastic seat, they resist the high temperatures and harsh chemicals of clean-in-place (CIP) processes. These valves have an extremely smooth surface, leaving no space for bacteria to grow. Quick-clamp connections, also known as tri-clamp fittings, are easily taken apart for regular cleaning. These valves are self-draining, so previous samples and cleaning chemicals won’t contaminate future samples. Both the seat and the silicone O-ring comply with FDA standards for direct contact with food and beverage.

To take samples, turn the thumb screw to open valves. Hang a bucket for sample collection from the bucket groove. Valves also have a leak detection port that will release a small amount of liquid to let you know when it’s time to replace all the valve seals.

Valves with a bent spout have a tab for connecting carbon dioxide testing devices. They’re often used for carbonated beverages. They shouldn’t be used with liquids that have solids in them, such as the grape skins or seeds in wine, as those can get caught in the outlet.
