... - 2ml Clear GC sample vials included blue ABS Screw Cap & Septa (Red PTFE/White Silicone Liner) This PTFE/Silicone septa with PTFE chemically inert before being penetrated and strongest repetitive sealing ability-recommended for multiple penetration sampling.
✅APPLICATION - Standard Autosampler Vial for HPLC & GC Chromatography, sample vials can be used for high performance liquid chromatography and gas chromatography for reliable analysis results.

...pta can reduce flat pins curving and When collecting in large quantities, prevent negative pressure from forming in the sample bottle. It is highly recommended to use pre-opening septa for Shimadzu, Hitachi and other autosamplers with finer needle specifications.
APPLICATION - Standard Autosampler Vial for HPLC & GC Chromatography, sample vials can be used for high performance liquid chromatography and gas chromatography for reliable analysis results.

PACK OF 100 || 100 sheets of no. 1 chromatography filter papers.
LARGE || Each sheet measures 23" x 18" and is very thin.
FOR SEPARATION || Used in chromatography to separate a sample into its component parts - Used to test for the presence of various materials, to monitor the rate and progress of a reaction or to determine the purity of a product.
USEFUL IN FUN EXPERIMENTS || Can be used for various experiments in the laboratory and at home - Paper allows students to separate most water-soluble inks into their original blended pigments to reveal their hidden coloration.
ABSORBENT || Absorbs liquids and provides more surface area for evaporation meaning more and faster evaporation which, in turn, means more vapor which is often desired.

Screw thread autosampler vials are made of borosilicate glass.
20mL Clear autosampler vial with 20mm jaw cap.
Sample Vials with unique thread design ensures consistent seal and can be reused, not volatile, easy to use.
Vials can be used for high performance liquid chromatography and gas chromatography for reliable analysis results.
Vials require fewer turns to make a tight seal, saving you time, especially when you consider how often vials need to be opened and closed, and how many samples you have.

SimPure Mixed Cellulose Ester (MCE) membrane filter is composed of cellulose acetate and cellulose nitrate. the MCE membrane is biologically inert, it is one of the most widely used membranes in analytical and research applications.
Gridded filters have clearly defined grid lines spaced at 3.1 mm intervals. The special ink used is non-toxic and completely free from bacterail growth inhibitors.
The gridded Mixed Cellulose Ester (MCE) membrane are ideal for colony counting and sterility testing.
The gridlines on the membrane's surface eliminate eye fatigue during colony-counting without affecting the growth of colonies. And allows color reactions to be easily observed.
Sterile gridded MCE membranes are unsupported, naturally hydrophilic membranes.

Kit includes bottle of electrolyte, 1 sanding disc and 6 screw-on cap membranes.
Response time (T95 - from 0 to 100 percent) = 8 seconds.
Flow dependence after 4 minutes = 25 percent.
