How do I use my Kemmerer bottle?

1. Lower the bottle on a line to the desired depth.
2. All-Angle™ and Tugger™ trip heads lock the seals open before lowering into the water. In the open position, water flows smoothly around the bottom seal and into the cylinder, thereby obtaining an accurate and representative water sample to the microgram (mg/L) level
3. If using a Tugger trip, you need to know when your sampler is at the correct depth for closing. Tie a small float on the line above the sampler at the desired sampling depth. When the float sinks, tug the line to close the bottle.
3. Drop a messenger or tug on the Tugger™ trip head
4. The 2 ears open and top seal falls, closing both ends.

How do I use a Van Veen Grab or Dredge?

1. The Van Veen Grab requires a winch (66-C10), winch mount (66-C52) and stainless steel cable (61-B14) for proper operation. Attach one end of the cable to your winch and the other to the dredge. Ensure that all connections are very tight to prevent loss of the sampler.
2. Set the Pinch-Pin (tripping mechanism) on the dredge. The Pinch-Pin must be inserted with the flat portion facing up and down. Be careful not to place fingers or hands on or into any pinch points.
3. Lower the dredge through the water column. Make sure that in the final 1-2 feet there is little to no disturbance.
4. Trip the dredge by allowing the line to become slack. The jaws should clamp shut, grabbing a sediment sample.
5. Winch the dredge to the surface in a slow, even manner.
6. Bring the dredge into your boat and tilt slightly to pur off the water. Be careful not to pour out the sediment!
7. Empty the contents of the dredge into a Ponar Wash Frame (188-E50).
8. Collect and handle samples as your procedures dictate.
9. Decontaminate the dredge between each unique sample location, or have a clean, dedicated dredge for each sample location.

How do I use a Turbidity Tube?

1. Fill tube with your water sample.
2. Look down the tube.
3. Drain off water until the secchi disk design is visible.
4. Record the reading on the scale.

How do I use a Standard Ponar Grab or Dredge?

1. The Standard Ponar Grab requires a Winch (66-C10), winch mount (66-C52) and stainless steel cable (61-B14) for proper operation. Attach one end of the cable to your winch and the other to the dredge. Ensure that all connections are very tight to prevent loss of the sampler.

How do I use a Secchi Disk?

1. Tie disk to calibrated line, lower into shallow water.
2. Record depth at which black and white quadrants cannot be distinguished.
3. Lower further, then raise until you can determine white from black again
4. Obtain the index of transparency- how turbid the water is.

How do I use a Petite Ponar Grab or Dredge?

1. Using a bowline knot, attach the necessary length of rope to the Wildco Petite Ponar dredge.
2. Set the Pinch-Pin (tripping mechanism) on the dredge. The Pinch-Pin must be inserted with the flat portion facing up and down. Be careful not to place fingers or hands on or into any pinch points.
3. Lower the dredge through the water column. Make sure that in the final 1-2 feet there is little to no disturbance.

6. Bring the dredge into your boat and tilt slightly to pur off the water. Be careful not to pour out the sediment!
7. Empty the contents of the dredge into a Wildco Wash Bucket (190-E25) or Ponar Wash Frame (188-E50).
8. Collect and handle samples as your procedures dictate.
9. Decontaminate the dredge between each unique sample location, or have a clean, dedicated dredge for each sample location.

How do I select the right Kemmerer?

For general sampling:
1200, 1204, 1220, 1230 – E32 kits: These range from 0.4 – 3.2 L and are constructed of 316 SS with polyurethane seals.
1200-C12 kits: 1.2 L and is constructed of transparent acrylic with polyurethane end seals.
For drum sampling and confined areas:
1204-E32, 1204-E42 kit: Small, compact bottles only 7.4” (187 mm) in length, designed especially to fit in small areas.
For trace organic sampling:
1204-E42, 1200-E42, 1200-G32, 1295-B32 kit: 1.2 L, 316 SS with teflon or silicone end seals; or all-Teflon bodies and seals. These can sample industrial solvents, strong acids and bases and other corrosive chemicals at temperatures to 450°F. Includes cable.

How do Beta bottles and Alpha bottles differ?

These bottles are very similar in use and appearance. Both are Van Dorn samplers that come in the same sizes and in PVC and transparent acrylic. The only differences are in the end seals and latex closing tubing. These differences are enough, however, to make the Beta™ better suited to sampling trace metals.

The blue polyurethane seal used in Alpha™ bottles may leach some mercury and phosphorous (among other contaminants). However, it is durable and long-lived. The white ASA plastic seal used in Beta™ bottles does not leach mercury. However, it is not as durable.

The black latex tubing on Alpha™ bottles is highly resistant to decay from sunlight and water. However, it may leach a very few heavy metals. The amber latex tubing on Beta™ bottles is less resistant to sun and water but does not leach contaminants.

How do 1200 and 1500 Kemmerers differ?

The 1200’s last longer because they have stainless steel parts (and sometimes stainless steel bodies). However, the 1500’s are more versatile because there are no metal parts to touch the sample.

1500’s come in acrylic and PVC; 1200’s come in stainless steel or acrylic only (no PVC). 1200’s have a wider variety of materials than 1500’s. Both come with silicone seals for trace metal sampling or polyurethane seals for general sampling.

How are liner tubes held?

1. The length of the core tube is 16 mm (d”) less than its corresponding liner tube. The nosepiece pushes the core catchers and liner tubes securely against the corer head.
2. Because the liner tube projects from the bottom core tube when the nosepiece is removed, you can easily grip the liner tube to remove it. You can also install the liner tube cap before removing the liner tube from the core tube.
3. Liner tubes and core tubes are the full length listed above.
