Plant Preservative Mixture (PPM), Plant Cell Technology
Price range: RM700.00 through RM5,071.00Brand:
Plant Cell Technology
Plant Preservative Mixture (PPM), is a broad-spectrum biocide/ for plant tissue culture. PPM™ is the ultimate solution to the never-ending struggle against microbial airborne, waterborne and endogenous contamination.
PPM™ is a heat-stable preservative/biocide which can be used to effectively prevent or reduces microbial contamination in plant tissue culture.
At optimum doses, PPM™, which stands for Plant Preservative Mixture™, is an extremely effective Preservative/Biocide, yet does not impair in vitro seed germination, callus proliferation and callus regeneration.
PPM™ prevents the germination of both bacteria and fungi spores. It is heat stable and therefore can be autoclaved with the media.
PPM™ can be, and should be used as a standard ingredient in plant tissue culture media, and is also substantially less expensive than commonly used antibiotics.
While PPM™ was principally designed to inhibit airborne contamination, waterborne contamination and contamination introduced from human contact, it can also — in many cases — be used to reduce endogenous contamination.
Despite the most stringent use of sterile techniques, the contamination of plant cell and plant tissue cultures remains a persistent problem that can result in losses ranging from small number of cultures to the loss of whole batches.

General description
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to the Enabling category of greener alternatives, thus aligns with “Design for energy efficiency”. Hole transport organic materials allow perfect energy level alignment with the absorber layer and therefore efficient charge collection, but are prone to degradation in ambient conditions. Click here for more information.
Application
In a recent study of a double-junction Quantum-Dot Light-Emitting Diodes (QD-LEDs), an impressive high quantum efficiency of 42.2% and a high current efficiency of 183.3 cd/A were achieved, which are comparable to those of the best vacuum-deposited tandem organic LEDs. Such high-efficiency devices are achieved by interface engineering of fully optimized single light-emitting units, which improves carriers′ transport/injection balance and suppresses exciton quenching induced by ZnO, and design of an effective interconnecting layer consisting of Poly-TPD mixed poly(9-vinylcarbazole) (PVK)/poly(3,4-ethylenedioxythiophene): polystyrene sulfonate/polyethylenimine ethoxylated-modified ZnO.
Indoor photovoltaics is one of the best sustainable and reliable energy sources for low-power consumption electronics, such as the rapidly growing Internet of Things.
In another recent study, Perovskite photovoltaic (PPV) cells with a mesoporous PPV (mPPV) structure using typical Spiro-OMeTAD as the hole transport layer (HTL) show the highest maximum power density (Pmax) of 19.9 μW/cm2 under 200 lux and 115.6 μWcm-2 under 1000 lux (without masking), which is among the best of the indoor PV. When PEDOT: PSS is replaced by Poly-TPD as HTL in the inverted PPV (iPPV) cell, the Pmax under indoor light improves significantly and is comparable to that of the best mesoporous mPPV cell.

RM3,561.00Brand:
Sigma-Aldrich
Synonyms
P3HT
General Description
Poly(3-hexylthiophene) (P3HT) is a regioregular semiconducting polymer. It is used in organic electronics primarily because of its regular end-to-end arrangement of side chain, which allows efficient p- p stacking of the conjugated backbones. On account of the alkyl side group, P3HT is rendered hydrophobic in neutral state. Solution-to-solid phase transformation and thin film formation of poly(3-hexylthiophene) (P3HT) was reported in a study.
Poly(3-hexylthiophene-2,5-diyl) (P3HT) is a poly(alkylthiophene) based semiconducting polymer that is hydrophobic at neutral state and has π-π conjugation in its backbone. It has a hole mobility is in the range of 10-3-10-1 cm2V-1s-1 and is commonly used in the development of field-effect transistors (FETs) for a wide range of applications.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with “Design for energy efficency”. Hole transport organic materials allow perfect energy level alignment with the absorber layer and therefore efficient charge collection, are prone to degradation in ambient conditions.
Applications
For the characterization and solid-state properties of this polymer, see J. Am. Chem. Soc. .
P3HT, an electron donor that acts as a semiconducting active layer in combination with an electron acceptor like fullerene derivative (6,6)-phenyl C61-butyric acid methylester (PCBM), can be used to fabricate bulk heterojunction (HJT) based organic solar cells (OSCs).[4][5][6][7] Volatile organic compounds (VOCs) and electric sensor devices can be developed by using Langmuir-Schaefer (LS) films of P3HT and poly(3-octylthiophene)(P3OT). It can also be used with polystyrene to process a nano-scaled polymeric coating through spray coating onto carbon nanotube (CNT) powders.
Poly(3-hexylthiophene-2,5-diyl) may be used to fabricate ZnO nanowire arrays based photodiode. Regio- regular poly(3-hexylthiophene-2,5-diyl) may find extensive use as a semiconducting layer in organic thin film field effect transistor (FETs).

This medium is suitable for the detection and enumeration of heat resistant molds in thermally processed fruits and fruit products.
Pigment production is a critical part of the identification of the fungus. The agar used in the medium is carefully screened to ensure correct pigment production by fungi such as Fusaria spp.
Composition of Potato Dextrose Agar
| Typical Formula * | gm/litre |
| Potato Extract | 4.0 |
| Glucose | 20.0 |
| Agar | 15.0 |
| pH 5.6 ± 0.2 @ 25°C |
Preparation of Potato Dextrose Agar, Oxoid
Suspend 39g in 1 litre of purified water and heat up to dissolve completely. Sterilise by autoclaving at 121°C for 15 minutes. Ensure the solution is well mixed before pouring.
To suppress the growth of bacteria, you can acidify the medium to pH 3.5 by adding 1 ml of lactic acid 10% SR0021 to each sterilized medium at 50°C. Note that the medium must not be heated after the addition of acid as it will destroy the gelling properties and results in hydrolysis of agar.
Storage Conditions and Shelf Life
Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
Store the prepared medium at 2-8°C.

Due to the presence of antibiotic Chloramphenicol in the formulation, the medium provides selectivity against bacteria as well as reducing harmful chemical handling in the laboratory.
Pre-supplemented Dichloran-Glycerol 18% (DG18) (ISO) Agar Base (Dehydrated), Oxoid Composition
| Typical Formula* | gm/litre |
| Casein Enzymatic digest | 5.0 |

| Chloramphenicol | 0.1 |
| pH 5.6 ± 0.2 @ 25°C |
Pre-supplemented Dichloran-Glycerol 18% (DG18) (ISO) Agar Base, Oxoid Preparation:
Suspend 15.8g per 500ml (31.6g/l) of distilled water and heat to dissolve completely. Before autoclaving add 220g of Glycerol per 1 litre of medium. Heat the complete solution gently to aid its dissolution of the glycerol. This has been found to be a key procedure to follow to allow proper dissolution of the glycerol. Sterilize by autoclaving at 121°C for 15 minutes. Cool to 50°C, mix well and pour into sterile Petri dishes.
Where bacterial overgrowth occurs from certain foods (raw meats) chlortetracycline hydrochloride at 50mg/L (dissolved in water and filter sterilised) is recommended.
Storage instructions
Store the dehydrated medium at 10–30°C and use before the expiry date.
Precautions
The dichloran compound used in this medium is Botran® 2,6-Dichloro-4-Nitro-Analine (CAS: 99-30-9).
Pre-supplemented DG18 (ISO) Agar (CM1151) contains Chloramphenicol in the base powder and is therefore considered a toxic compound which should be handled in accordance with good industrial hygiene and safety practice. Always consult the MSDS before handling the powder.
