Glass Microfiber filters, grade MG 1387/1 are used as pre-filters. Application: Analytical Sample Preparation
Filter Paper for Qualitative Analysis, Grade 1289, made from fine pulp and linters with a content of more than 95% α-cellulose. Ash content ≤ 0.1% according to DIN 54370. Wet strength. These qualitative filter papers are used for analytical purposes and general laboratory work when not gravimetric analyses are required. Their wet strength allows them to be used for pressure or vacuum filtration. Also, if necessary, the filter cake can easily be removed from the filter with a water jet or spatula.
Filter boards, Grade C 160, with increased wet strength for the filtration and absorption of liquids.
The Q3400 grade is made from 100% high purity quartz microfibers and pre-treated with heat to ensure excellent weight and dimensional stability. The filters are particularly well suited for emission control at temperatures of up to 900°C and when the highest cleanliness requirements are placed on the filter. An analysis of trace elements is carried out for each batch and documented with a certificate of analysis. Application examples: - Determination of the dust mass concentration according to EN 13284 1: 2001 - Emission monitoring at high temperatures (air pollution) - Analysis of hot and acidic gases - Analysis of trace elements - Analytical and gravimetric analysis - Determination of the mass concentration of PM10/PM2.5 in the exhaust gas according to ISO 23210: 2017
Filter Paper for Quantitative Analysis, Grade 391, made from 100% cotton linters ash-free (ash content ≤ 0.01% according to DIN 54370). Wet strength. Color coded box to facilitate selection. These filter papers are used for quantitative and gravimetric analysis as well as for pressure or vacuum filtration. They are made from 100% cotton linters with >98% alpha cellulose content and are acid washed to achieve ash free and high purity.
Filter Paper for Chromatography, Grade FN 30 This high-purity paper grade is not only ideal for blotting and chromatography, but also for applications where the absorption properties of the paper are important, such as in diagnostics and life science.
Filter Paper for Qualitative Analysis, Grade 1289, made from fine pulp and linters with a content of more than 95% alpha cellulose. Ash content ≤ 0.1% according to DIN 54370. Wet strength. These qualitative filter papers are used for analytical purposes and general laboratory work if not gravimetric analyses are required. Due to their wet strength they can be used for pressure or vacuum filtration. Also, if necessary, the filter cake can be removed effortlessly from the filter by using a water jet or spatula.
Disposable Gelatine Filters; sterile; individually packed in 3 polyethylene bags with label on innermost bag; 10pcs
Filter Paper for Qual. -Techn. Analysis, Grade100/N, Smooth, Sheet Roll Filter material: Cotton Linters and Refined Pulp (> 95 % alpha-cellulose)
The stainless steel syringe filter holder Ø 25 mm is recommended for the filtration of volumes of up to about 100 ml. No seal required: the upper part can easily be mounted on the lower part with the enclosed clamping tool and seals completely. The filter support in the lower and upper part ensures filtration in both directions. Heat resistant and the chemical compatibility depends on the inserted filter type only.
Polycarbonate filter holder; top part
3-way valve for syringe filtration attachments. In conjunction with a syringe and a filtration attachment on the outlet side, continuous filtration can be carried out with this valve.
Stainless steel filter holder 142 mm_ TC. For In-Line installation. GMP-complying. The inlet and outlet connectors are sanitary flanges, which are integral parts of the top and bottom plates. They assist in making the holder easy to clean and simplify the In-Line installation. A suitable clamp allows, with the legs removed, to adjust the outlet at any height. With silicone-O-ring gaskets.
Stainless steel filtration device with 2 liter infusion cylinder for sample preparation and sterile filtration of serum This device is ideally suited for the separation of undissolved constituents from samples in order to determine the proportions of sludge samples that can be eluted with water. With a capacity of 2 liters, the device can handle the entire sample volume be filled; the large opening makes it easier to fill in the liquid. Pressure filtration avoids the loss of volatile components. A filter area of 130 cm² guarantees short filtration times. The device is also used for sterile filtration of liquids that are difficult to filter, such as serum.
Glass vacuum filtration device. Glass filter holders are available for both low volume filtration with a 30 ml attachment (filter diameter 25 mm) as well as for larger volumes with 250 ml attachment (filter diameter 47/50 mm). They can be sterilized either through autoclave (max. 134°C) or dry heat (max. 180°C). The filter-supporting glass frit ensures an even distribution of residues.
