Yes, it is possible to use these items for the control of static charge.

You are not required to use the StableWeigh Vessel with the vacuum manifold. You may use any container that fits within the outer sleeve. It has an inner diameter of 3.4 inches.

We are not familiar with that method and have not done any testing of this product with it.

We recommend a pump that has a minimum of 1.2 CFM air flow. If you experience uneven pull across the different stations please check to make sure the stopcocks have not come loose. This can lead to loss of vacuum. Look on the bottom of the manifold and check the nut holding the stopcock in place.

We no longer include a printed out list of the weights in the box. We plan to have a downloadable sheet in the future but it is not yet available.

They are different brands of the same type of equipment.

This product does not have a certificate of analysis.

The EPA approves methods based on the chemistry contained within, not the equipment that is used. While the method specifically state to use evaporation dishes of porcelain, high silica glass, or platinum; laboratories are free to use other materials. You must perform a duplicate QC analysis with the listed equipment and the alternative equipment. Keep this data on file. There are other documents found on this page (http://www.envexp.com/products/1-Wet_Chemistry/PW-Solids_Testing/TDSSW-StableWeigh_for_TDS) that will help with any other requirements.

We do not currently have that o-ring as a replacement part.

It is not programmable. This controller is the same as is found on our regular HotBlocks. You can pick a temperature up to 150°C and it will hold at that temperature for as long as the block is turned on. The block is intended for evaporation of the liquid only. You will still need an oven capable of maintaining 180°C for the second stage of the drying process.

Some size beakers will fit in the filling station. You would need to no use the inner shell to allow room for them to fit. There is a hole on the floor of each station that allows the vacuum to pull. It would need to remain uncovered.

These are the same filters as F92447MM, Washed and Dried Filters. They are glass fiber, 1.5 micron.

Please use part number TDS100S to request a sample pack of the StableWeigh vessels.

We do offer sample packs of the TDS vessels. Use item TDS100S. If you want a sample pack of the washed and dried filters please use item F92447MMS.

We have not put a recycling code on this product. It does contain a fluoropolymer, so it would be a category 7 at best. Check with your local recycling center for more guidance.

Standard Methods does not require replicate weights to obtain the initial tare weight of the evaporating vessel. It only requires replicate weights on initial weights for filters for TSS and on the final dry weight for all residue analyses.

The StableWeigh vessels haven’t changed size so they should fit in your filling station.

Standard Methods 2540C.3.b, 23rd Edition, does not require that the evaporating dish be weighed twice for verification of stability. It only states to heat the dish to 180 ± 2°C for ? 1 h in an oven, cool dishes to ambient temperature, and weigh. Our StableWeigh vessels meet these requirements and are specifically cited in SM 2540B.2.a, 23rd Edition, as an approved sample dish.

We do not sell the support stand separately.

The vessel can hold approximately 300 mL of liquid.

We highly recommend that some form of static control is employed when using our StableWeigh vessels. We have several static control products available if you do not currently have a system in place.

This is made of plastic, metal, and electrical components. This does not contain any radioactive components.

The StableWeigh vessels can hold about 300 milliliters.

Currently, StableWeigh is only method compliant with the ASTM D5907 method. There is an update coming very soon to SM2540 which will specifically allow for our vessels to be used. The method update will actually mention StableWeigh by name.

Any type/model of steam bath can be used to evaporate the samples to dryness. The method allows for you to use an oven to evaporate the samples as well. We recommend the temperature to be set between 103-105 C. Our filling stations support the vessel during filtration. They should then be placed in our modular rack, TDS200R, throughout the rest of the test.

Dimensions of 5-place modular rack:\r\nLeft to Right - 14.25\" \r\nFront to Back - 12.75\"\r\nTall - 4\"\r\n

Although they may look like plastic bags, they are vessels made from a proprietary polymer blend.

We do offer samples of our StableWeigh vessels. The part number is TDS100S.

These vessels were designed to replace traditional crucibles. They come preconditioned and preweighed so they are ready to use right out of the box. Filter your sample through a 1.5 um washed and dried glass fiber filter into the vessel. Place the vessel into an oven/steam bath to evaporate to dryness. Bake in 180C oven for 1 hour. Cool in desiccator to balance temperature (about 15 mins). Weigh the vessel with the residue. Calculate your TDS value. Discard vessel.
