Pyrotell was the first LAL reagent licensed by the US FDA. It is easy to use and is available in both economical Multi-Test Vials (MTVs) and convenient Single Test Vials (STVs). Pyrotell is a robust reagent, producing firm, easily read clots and is resiliant to interfering substances. The gel-clot test does not require sophisticated equipment and software and is the simplest LAL test to implement.


Pyrotell is available in a variety of sensitivities: 0.03 EU/mL; 0.06 EU/mL; 0.125 EU/mL; and 0.25 EU/mL.

Sample to LAL Ratio

Reconstituted Pyrotell reagent is used at a ratio of 1:1 and a volume of 100 μL/test.

Pyrotell-T is used to quantify endotoxin in kinetic turbidimetric tests. Pyrotell-T can be used with the Pyros Kinetix® Flex tube reader and incubating microplate readers. When used with the Pyros Kinetix Flex tube reader, Pyrotell-T gives a highly economic, flexible and sensitive LAL assay.


When used in a Pyros Kinetix Flex tube reader, the maximum sensitivity is 0.001 EU/mL. The unique formulation of Pyrotell-T allows a wide selection of standard curves to be used, giving the user flexibility, speed, and ease in performing assays.

Sample to LAL Ratio

The ratio of sample to LAL is determined by personal preference and sample chemistry (interference patterns). Reconstituted Pyrotell-T LAL reagent is used at a ratio of 1:1 or 4:1 and a LAL volume of 100 μL/well (48 tests/vial) or 50 μL/well (96 tests/vial).

Pyrochrome is a versatile quantitative reagent that is used to perform kinetic or endpoint assays. It is a sensitive and flexible reagent that can be used for testing in compliance with the USP, EP and JP bacterial endotoxins test chapter. Pyrochrome is offered with either Pyrochrome Buffer or for endotoxin-specific testing, with Glucashield® Buffer. Pyrochrome can be used with the new Pyros Kinetix® Flex tube reader at a 1:1 and economical 4:1 sample to LAL ratio.

Pyrochrome can be used for a wide variety of endotoxin tests, ranging from standard water testing to samples requiring high sensitivity, such as intrathecal products and those requiring high dilutions to overcome interference.

It is also offered in a diazo kit for endpoint tests. (The diazo reagents shift the absorption wavelength making it especially useful for testing samples with color interference.)


The sensitivity for chromogenic assays is determined by the lowest standard concentration on the standard curve used for the assay. The maximum sensitivity of Pyrochrome is 0.001 EU/mL when run in Pyros Kinetix Flex tube reader or incubating microplate reader with Glucashield Buffer.

Sample to LAL Ratio

In the Pyros Kinetix Flex tube reader, Pyrochrome can be used at an economical ratio of 4:1 using 50 μL of reagent per well or at 1:1 using 100 μL/well. In a microplate reader, the reagent is used at a ratio of 1:1 and a volume of 50 μL/well (60 tests/vial) or 100 μL/well (30 tests/vial).

Control Standard Endotoxin (CSE)


Control Standard Endotoxin (CSE) is a widely used standard for endotoxin testing. It is a purified extract from E.coli O113:H10, the same strain used for the United States Pharmacopeia and the European Pharmacopeia Reference Standard Endotoxin (RSE).

CSE is an economic alternative to the RSE. CSEs are standardized against the RSE as indicated on the Certificate of Analysis, so the results can be reported in Endotoxin Units (EU) and International Units (IU). CSE can be used for all routine LAL testing. A 10 ng/vial CSE is made specifically for use with our Pyrochrome chromogenic reagent.

Depyrogenation Controls

In addition to their use as standards for controlling LAL test, the 0.5 μg CSEs can be used for validation of depyrogenation processes. They may be used directly, without reconstitution, as depyrogenation indicators (recommended for 0.5 μg) or can be reconstituted and endotoxin added to challenge articles (recommended for 125 μg).

LAL Reagent Water (LRW)

lal reagent

LRW is intended for reconstitution of LAL reagents and CSE, and to dilute samples and standards for LAL assays. LRW is not for human or animal injection. LRW contains less than 0.001 EU/mL endotoxin and less than 1.56 pg/mL glucan.
