Disposable Liquid Samplers

Toss these samplers after you collect and transfer liquid samples—they’re disposable to reduce the risk of cross contamination.
Style C sampler bottles have a leakproof lid, so they’re good for shipping and storing small samples. They have a needle with a luer lock connection, so it's easy to remove or change the needle. The membrane seals automatically after you remove the needle. These samplers come with a tamper seal label to put over the lid, showing if the bottle has been opened.

Liquid Samplers


Steel with
Pull Ring
Collect liquid samples from drums, tanks, and other containers. These samplers open and close, so you can gather samples at a targeted depth in your tank. All are autoclavable, so you can sterilize them with steam.
Stainless steel samplers are the most durable and chemical resistant. They also resist corrosion. Less porous and less likely to scratch than plastic, they’re easy to sanitize. Open and close them by pulling up on the center ring.
Liquid Samplers for Extra-Large Tanks

Lower these samplers with a chain or cable to collect samples from the bottom of large tanks. Also known as bomb samplers, they open automatically when they touch the bottom of the tank or they can be opened manually with a pull line.
Large-Capacity Sterile Disposable Liquid Samplers

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 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.
These bags are best for taking large samples. They’re 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. Manufactured free of contaminants and allergens, they are BPA- and latex-free. They’re also TSE/BSE compliant, so they’ve never come into contact with any animal products.
These liquid samplers are typically used with sampling tube fittings.

Vacuum Samplers for Liquids

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.

Plastic Dippers for Harsh Chemicals
Collect and transfer acids, solvents, and other harsh chemicals. The bowl and handle on these dippers are PTFE, so they resist chemicals better than standard plastic dippers. For added durability, the handle has a stainless steel core. The threaded design lets you detach the bowl from the handle for easy cleaning and storage. To make the dipper longer, thread together as many extension handles (sold separately) as you need to reach your desired length.

Stainless Steel Measuring Spoon Sets



Measure small amounts of your material or ingredients. All spoons are stainless steel, so they’re easy to clean and sanitize.
Spoons with a long handle can reach over a foot to get to the bottom of large containers and bulk material sacks.
Flat-bottom spoons rest on surfaces without tipping over. You can use them as weigh boats.
Spoons that meet NSF/ANSI 2 adhere to sanitary standards for food-processing environments.

Stainless Steel Bleed Rings


- For Use With: Air, Natural Gas, Oil, Steam, Water
Create an access point in a pipe line where corrosion is a concern. Often used to relieve pressure or siphon and sample liquids, these bleed rings act as a port between two pipe flanges, eliminating the need to take apart your flanges to get inside. They include a plug, or replace the plug with your own fitting, valve, or probe. Made of stainless steel, these bleed rings resist rusting.
Install these bleed rings between two pipe flanges along with a gasket on both sides to avoid leaks. They’re designed to fit flanges that meet ASME B16.5.
304 stainless steel bleed rings keep corrosion at bay in wet conditions but will start to corrode when exposed to salt water. 316 stainless steel bleed rings withstand wet conditions as well as chemicals and salt water.

Steel Bleed Rings


- For Use With: Air, Natural Gas, Oil, Steam, Water
Access the inside of a pipe line to vent pressure, drain liquid, or take samples. These bleed rings act as a port where two pipe flanges meet, so you don’t have to disassemble your flanges to get inside. They include a plug, or you can attach your own fitting, valve, or probe. Made of steel, these bleed rings should be used in noncorrosive environments to prevent rusting.
Install these bleed rings between two pipe flanges along with a gasket on both sides to avoid leaks. They’re designed to fit flanges that meet ASME B16.5.

Sanitary Sampling Valves


- Valve Type: Stop Cock
- For Use With: Food, Beverage
- Specifications Met: FDA Compliant 21 CFR 177.2600, FDA Compliant 21 CFR 177.1550
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.
